The CVE-2021-31955 bug \u201cis affiliated with SuperFetch, a feature first introduced in Windows Vista that aims to reduce software loading times by pre-loading commonly used applications into memory,\u201d they explained.\n\nThe second flaw, CVE-2021-31956, is an Elevation of Privilege vulnerability and heap-based buffer overflow. Kaspersky said that attackers used this vulnerability alongside Windows Notification Facility (WNF) \u201cto create arbitrary memory read/write primitives and execute malware modules with system privileges.\u201d\n\n\u201cOnce the attackers have used both the Chrome and Windows exploits to gain a foothold in the targeted system, the stager module downloads and executes a more complex malware dropper from a remote server,\u201d they continued. \u201cThis dropper then installs two executables, which pretend to be legitimate files belonging to Microsoft Windows OS. The second of these two executables is a remote shell module, which is able to download and upload files, create processes, sleep for certain periods of time, and delete itself from the infected system.\u201d\n\nBoris Larin, senior security researcher with Kaspersky\u2019s Global Research and Analysis Team (GReAT), said that the team hasn\u2019t been able to link these highly targeted attacks to any known threat actor: Hence the name PuzzleMaker and the determination to closely monitor the security landscape \u201cfor future activity or new insights about this group,\u201d he was quoted as saying in the press release.\n\nIf the current trend is any indication, expect to see more of the same, Larin said. \u201cOverall, of late, we\u2019ve been seeing several waves of high-profile threat activity being driven by zero-day exploits,\u201d he said. \u201cIt\u2019s a reminder that zero days continue to be the most effective method for infecting targets. Now that these vulnerabilities have been made publicly known, it\u2019s possible that we\u2019ll see an increase of their usage in attacks by this and other threat actors. That means it\u2019s very important for users to download the latest patch from Microsoft as soon as possible.\u201d CVE-2021-31199/CVE-2021-31201The two Enhanced Cryptographic Provider Elevation of Privilege vulnerabilities are linked to the Adobe Reader bug that came under active attack\u00a0last month (CVE-2021-28550), ZDI explained. \u201cIt\u2019s common to see privilege escalation paired with code execution bugs, and it seems these two vulnerabilities were the privilege escalation part of those exploits,\u201d he explained. \u201cIt is a bit unusual to see a delay between patch availability between the different parts of an active attack, but good to see these holes now getting closed.\u201d CVE-2021-33739Breen noted that privilege escalation vulnerabilities such as this one in the Microsoft DWM Core Library are just as valuable to attackers as RCEs. \u201cOnce they have gained an initial foothold, they can move laterally across the network and uncover further ways to escalate to system or domain-level access,\u201d he said. \u201cThis can be hugely damaging in the event of ransomware attacks, where high privileges can enable the attackers to stop or destroy backups and other security tools.\u201d\nSource: threatpost.com (Click Link)Recent News* https://www.blackhatethicalhacking.com/wp-content/uploads/2021/06/Untitled-design-1-1-90x90.png RockYou2021: largest password compilation of all time leaked online \u2013 8.4 billion entries17 hours ago\n* https://www.blackhatethicalhacking.com/wp-content/uploads/2021/06/microsoft-exploit-90x90.jpg Windows Container Malware Targets Kubernetes Clusters1 day ago\n* https://www.blackhatethicalhacking[...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-01T20:02:37.506753Z"}, {"uuid": "9c6b98c9-e5f2-49ed-9d36-4596f7824703", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-31194", "type": "seen", "source": "https://t.me/hacking_Attack/8310", "content": "Black Hat Ethical Hacking\nWormable Windows Bug Opens Door to DoS, RCE\n\nhttps://www.blackhatethicalhacking.com/wp-content/uploads/2017/11/black-hat-locks-and-electronics.jpg Wormable Windows Bug Opens Door to DoS, RCEPost Views: 89 \nReading Time: 2 Minutes\nMicrosoft\u2019s May 2021 Patch Tuesday updates include fixes for four critical security vulnerabilities, including a\u00a0patch for a concerning wormable vulnerability found in the Windows OS.\nThe good news is that none of the vulnerabilities are being actively exploited in the wild, according to Microsoft, though three are listed as publicly known. The fixes\u00a0address security flaws across Microsoft Windows, .NET Core and Visual Studio, Internet Explorer (IE), Microsoft Office, SharePoint Server, Open-Source Software, Hyper-V, Skype for Business and Microsoft Lync, and Exchange Server. Besides the four critical bugs, 50 are rated \u201cimportant\u201d and one is moderate in severity. Critical Microsoft Security Patches for May 2021The critical bugs in this month\u2019s Patch Tuesday release are:\n\n* CVE-2021-31166: A wormable HTTP protocol-stack issue in Windows 10 and some versions of Windows Server allowing remote code-execution (RCE)\n* CVE-2021-26419: A scripting-engine memory corruption vulnerability in Internet Explorer 11 and 9 allowing RCE\n* CVE-2021-31194: An RCE bug in the Microsoft Windows Object Linking and Embedding (OLE) Automation\n* CVE-2021-28476: An RCE vulnerability in Microsoft Windows Hyper-V CVE-2021-31166 \u2013 WormableThis most concerning critical bug for researchers is an HTTP protocol-stack issue that would allow RCE with kernel privileges or a denial-of-service (DoS) attack. The HTTP protocol stack enables Windows and applications to communicate with other devices; it can be run standalone or in conjunction with Internet Information Services (IIS).\n\n\u201cIf exploited, this vulnerability could enable an unauthenticated attacker to send a specially crafted packet to a targeted server utilizing the HTTP protocol stack (http.sys) to process packets and ultimately, execute arbitrary code, and take control of the affected system,\u201d Eric Feldman, cybersecurity researcher with Automox, wrote in an analysis.\nSee Also: Lemon Duck Cryptojacking Botnet Changes Up Tactics Worse, Microsoft noted that the bug is wormable, so that it could be used to self-replicate across the internal network and affect internal services that may not have been exposed.\n\n\u201cThe vulnerability announced has the potential to be both directly impactful and is also exceptionally simple to exploit, leading to a remote and unauthenticated DoS (Blue Screen of Death) for affected products,\u201d Steve Povolny, head of advanced threat research and principle engineer at McAfee, said via email. \u201cWhile this vulnerability has the potential to lead to code execution in the Windows kernel, this type of weaponization is a much higher bar for exploitation. However, if RCE can be achieved, cybercriminals would likely have the capability to create a worm, leading to self-propagation of the vulnerability across networks and the internet.\u201d\n\n\u201cFor ransomware operators, this kind of vulnerability is a prime target for exploitation,\u201d Kevin Breen, director of cyber-threat research at Immersive Labs, told Threatpost. \u201cWormable exploits should always be a high priority, especially if they are for services that are designed to be public facing. As this specific exploit would not require any form of authentication, it\u2019s even more appealing for attackers, and any organization using HTTP.sys protocol stack should prioritize this patch.\u201d\n\nDustin Childs, researcher with Trend Micro\u2019s Zero Day Initiative (ZDI), noted in a blog, \u201cBefore you pass this aside, Windows 10 can also be configured as a web server, so it [...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-01T20:02:43.895833Z"}, {"uuid": "4b5b4aab-538e-462c-9487-9047e8d08383", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-31199", "type": "seen", "source": "https://t.me/hacking_Attack/12055", "content": "nt.

CVSS 5.2\n* CVE-2021-31201\u00a0\u2013 Microsoft Enhanced Cryptographic Provider Elevation of Privilege Vulnerability. Rating: Important. CVSS 5.2 CVE-2021-33742This RCE vulnerability exploits MSHTML, a component used by the Internet Explorer engine to read and display content from websites.The bug could allow an attacker to execute code on a target system if a user views specially crafted web content. The Zero Day Initiative\u2018s (ZDI\u2019s) Dustin Childs noted in his Patch Tuesday analysis that since the vulnerability is in the Trident (MSHTML) engine itself, many different applications are affected, not just Internet Explorer. \u201cIt\u2019s not clear how widespread the active attacks are, but considering the vulnerability impacts all supported Windows versions, this should be at the top of your test and deploy list,\u201d he recommended.\n\nThe vulnerability doesn\u2019t require special privilege to exploit, though the attack complexity is high, if that\u2019s any consolation. An attacker would need to do some extra legwork to pull it off, noted Satnam Narang, staff research engineer at Tenable, in an email to Threatpost on Tuesday.\n\nImmersive Labs\u2019 Kevin Breen, director of cyber threat research, noted that visiting a website in a vulnerable browser is \u201ca simple way for attackers to deliver this exploit.\u201d He told Threatpost via email on Tuesday that since the library is used by other services and applications, \u201cemailing HTML files as part of a phishing campaign is also a viable method of delivery.\u201d Sophos decreed\u00a0this one to be the top concern of this month\u2019s crop, given that it\u2019s already being actively exploited by malicious actors. See Also: Jeff Moss, aka Dark Tangent, the person who founded DEF CON and Black Hat CVE-2021-31955, CVE-2021-31956: Used in PuzzleMaker Targeted MalwareCVE-2021-31955 is an information disclosure vulnerability in the Windows Kernel, while CVE-2021-31956 is an elevation of privilege vulnerability in Windows NTFS. The ZDI\u2019s Childs noted that CVE-2021-31956 was reported by the same researcher who found CVE-2021-31955, an information disclosure bug also listed as under active attack. They could be linked, he suggested: \u201cIt\u2019s possible these bugs were used in conjunction, as that is a common technique \u2013 use a memory leak to get the address needed to escalate privileges. These bugs are important on their own and could be even worse when combined. Definitely prioritize the testing and deployment of these patches.\u201d\n\nHe was spot-on. On Tuesday, Kaspersky announced that its researchers had discovered a highly targeted malware campaign launched in April against multiple companies, in which a previously unknown threat actor used a chain of Chrome and Windows zero-day exploits: Namely, these two.\n\nIn a press release, Kaspersky said that one of the exploits was used for RCE in the Google Chrome web browser, while the other was an elevation of privilege exploit fine-tuned to target \u201cthe latest and most prominent builds\u201d of Windows 10.\n\n\u201cRecent months have seen a wave of advanced threat activity exploiting zero-days in the wild,\u201d according to the release. \u201cIn mid-April, Kaspersky experts discovered yet a new series of highly targeted exploit attacks against multiple companies that allowed the attackers to stealthily compromise the targeted networks.\u201d\n\nKaspersky hasn\u2019t yet found a connection between these attacks and any known threat actors, so it\u2019s gone ahead and dubbed the actor PuzzleMaker. It said that all the attacks were conducted through Chrome and used an exploit that allowed for RCE. Kaspersky researchers weren\u2019t able to retrieve the code for the exploit, but the timeline and availability suggests the attackers were using the now-patched CVE-2021-21224\u00a0[...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-01T20:02:38.010201Z"}, {"uuid": "77153de7-536f-45af-9ded-201889e360dc", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-31194", "type": "seen", "source": "https://t.me/hacking_Attack/8311", "content": "is impacted as well. Definitely put this on the top of your test-and-deploy list.\u201d CVE-2021-26419This second critical bug affecting Microsoft\u2019s legacy browser allows RCE, and offers several avenues of attack, according to researchers.\n\n\u201cIn a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website,\u201d explained Feldman. \u201cAn attacker could also embed an ActiveX control marked \u2018safe for initialization\u2019 in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.\u201d\nSee Also: Offensive Security Tool: EyeWitness The best way to counteract this bug is ditching IE, noted Breen.\n\n\u201cInternet Explorer needs to die \u2013 and I\u2019m not the only one that thinks so,\u201d he told Threatpost. \u201cIf you are an organization that has to provide IE11 to support legacy applications, consider enforcing a policy on the users that restricts the domains that can be accessed by IE11 to only those legacy applications. All other web browsing should be performed with a supported browser.\u201d CVE-2021-31194The third critical bug exists in the Microsoft Windows OLE Automation, which in and of itself should place it on the priority-patch list, according to researchers.\n\n\u201cTo exploit the vulnerability, an attacker could host a specially crafted website designed to invoke OLE automation through a web browser,\u201d explained Justin Knapp, Automox researcher. \u201cHowever, this approach requires that the attacker bait a user into visiting the maliciously crafted website.\u201d\n\nHe pointed out that OLE technology has frequently been used to mask malicious code within documents and for linking to external files that infect systems with malware.\n\n\u201cIn 2020, the CISA released an alert detailing the top 10 routinely exploited vulnerabilities, which identified Microsoft\u2019s OLE as the most commonly exploited technology by state-sponsored cyber-actors,\u201d he said. \u201cConsidering the prevalent exploitation of OLE vulnerabilities, including those that had been flagged years ago, organizations should immediately prioritize patching all outstanding OLE vulnerabilities.\u201d See Also: Hacking Stories: Xbox UndergroundCVE-2021-28476The last critical bug is found in Windows Hyper-V, which is a native hypervisor that can create and run virtual machines on x86-64 systems running Windows. It can allow an attacker to execute arbitrary code, Knapp said:\u00a0\u201cTo exploit this vulnerability, an attacker could run a specially crafted application on a Hyper-V guest that could cause the Hyper-V host operating system to execute arbitrary code when it fails to properly validate vSMB packet data. Successful exploitation could enable an attacker to run malicious binaries on Hyper-V virtual machines or execute arbitrary code on the host system itself.\u201d\n\nThat said, Microsoft noted that an attacker is more likely to abuse the bug for DoS attacks in the form of a system crash rather than RCE, Childs pointed out, which mitigates the vulnerability\u2019s CVSS score of 9.9.\n\n\u201cBecause of this, it could be argued that the attack complexity would be high, which changes the CVSS rating to 8.5,\u201d he said. \u201cThat still rates as high-severity, but not critical. Still, the bug check [system crash] alone is worth making sure your Hyper-V systems get this update.\u201d Publicly Disclosed VulnerabilitiesChris Goettl, senior director of product management at Ivanti, told Threatpost that the biggest patching priority should be the publicly disclosed bugs \u2013 even though there is as yet no known malicious exploitation.\n\n\u201cThe top concern from the Microsoft updates this month is the update for Microsoft Exchange that[...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-01T20:02:43.708759Z"}, {"uuid": "c902f4e2-f8d1-4db0-b6cc-6d6afb1d8fb9", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-31195", "type": "seen", "source": "https://t.me/hacking_Attack/8312", "content": "includes the fix for CVE-2021-31207, which made its debut in the 2021 Pwn2Own competition,\u201d he said.\n\nThe bug tracked as CVE-2021-31207 is only rated as \u201cmoderate,\u201d but the \u201csecurity feature-bypass exploit was showcased prominently in the Pwn2Own contest and at some point details of the exploit will be published,\u201d Goettl explained. \u201cAt that point threat actors will be able to take advantage of the vulnerability if they have not already begun attempting to reverse engineer an exploit.\u201d\n\nThere two other publicly disclosed vulnerabilities resolved by Microsoft this month that exist in Common Utilities, found in the NNI open-source toolkit (CVE-2021-31200), and in .NET and Visual Studio (CVE-2021-31204).\n\n\u201cCommon Utilities and .NET and Visual Studio are less likely to be targeted, but due to the public disclosures they should not be ignored for long,\u201d Goettl added.

It\u2019s not clear what the range on such an attack would be, but you should assume some proximity is needed. You\u2019ll also note this CVE is from 2020, which could indicate Microsoft has been working on this fix for some time.\u201d Windows Graphics, SharePoint Server PatchesA trio of local privilege escalation flaws \u2013 two in the Windows Graphics Component (CVE-2021-31188, CVE-2021-31170) and one in SharePoint Server (CVE-2021-28474) \u2013 caught Breen\u2019s eye.\n\nAs for the first two, he noted they could be chained with another bug, such as the wormable bug listed above, to become highly dangerous and allow for WannaCry-style attacks.\n\n\u201cThis kind of vulnerability is often used by attackers after they have already gained a foothold through an initial infection vector, like phishing or via another exploit like the RCE in HTTP.sys (CVE-2021-31166),\u201d Breen noted via email. \u201cThe attackers are looking to increase their privileges so they can move laterally across a network or gain access to other accounts that may have access to more sensitive information.\u201d\n\nMeanwhile, the SharePoint bug allows an authenticated attacker to run code on remote SharePoint Servers.\n\n\u201cAs this is post-authentication, it\u2019s likely to be used as part of post-exploitation and lateral movement phases of an attack, rather than the initial-infection vector,\u201d Breen said. \u201cAttackers could gain access to sensitive documents or even replace real documents with weaponized versions, enabling the compromise of more user devices across the organization\u2019s network.\u201d Microsoft Exchange Server PatchesMicrosoft also patched four vulnerabilities in Microsoft Exchange Server.

You\u2019ll also note this CVE is from 2020, which could indicate Microsoft has been working on this fix for some time.\u201d Windows Graphics, SharePoint Server PatchesA trio of local privilege escalation flaws \u2013 two in the Windows Graphics Component (CVE-2021-31188, CVE-2021-31170) and one in SharePoint Server (CVE-2021-28474) \u2013 caught Breen\u2019s eye.\n\nAs for the first two, he noted they could be chained with another bug, such as the wormable bug listed above, to become highly dangerous and allow for WannaCry-style attacks.\n\n\u201cThis kind of vulnerability is often used by attackers after they have already gained a foothold through an initial infection vector, like phishing or via another exploit like the RCE in HTTP.sys (CVE-2021-31166),\u201d Breen noted via email. \u201cThe attackers are looking to increase their privileges so they can move laterally across a network or gain access to other accounts that may have access to more sensitive information.\u201d\n\nMeanwhile, the SharePoint bug allows an authenticated attacker to run code on remote SharePoint Servers.\n\n\u201cAs this is post-authentication, it\u2019s likely to be used as part of post-exploitation and lateral movement phases of an attack, rather than the initial-infection vector,\u201d Breen said. \u201cAttackers could gain access to sensitive documents or even replace real documents with weaponized versions, enabling the compromise of more user devices across the organization\u2019s network.\u201d Microsoft Exchange Server PatchesMicrosoft also patched four vulnerabilities in Microsoft Exchange Server. The flaws (CVE-2021-31198, RCE; CVE-2021-31207, spoofing; CVE-2021-31209, security bypass; and CVE-2021-31195, RCE), are all rated important or moderate.\n\n\u201cCVE-2021-31195 is attributed to Orange Tsai of the DEVCORE research team, who was responsible for disclosing the ProxyLogon Exchange Server\u00a0vulnerabilities that [were] patched in an out-of-band release back in March,\u201d Satnam Narang, staff research engineer with Tenable, told Threatpost. \u201cWhile none of these flaws are deemed critical in nature, it is a reminder that researchers and attackers are still looking closely at Exchange Server for additional vulnerabilities, so organizations that have yet to update their systems should do so as soon as possible.\u201d\n\nAnd finally, Ivanti\u2019s Goettl noted that several Microsoft products have reached end-of-life and won\u2019t be getting support going forward.\n\n\u201cThis month marks the final update for several Windows 10 and Server [...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-02T01:03:18.737353Z"}, {"uuid": "9447541d-af2b-4070-be03-170e9e298f9d", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-31195", "type": "seen", "source": "https://t.me/hacking_Attack/8312", "content": "includes the fix for CVE-2021-31207, which made its debut in the 2021 Pwn2Own competition,\u201d he said.\n\nThe bug tracked as CVE-2021-31207 is only rated as \u201cmoderate,\u201d but the \u201csecurity feature-bypass exploit was showcased prominently in the Pwn2Own contest and at some point details of the exploit will be published,\u201d Goettl explained. \u201cAt that point threat actors will be able to take advantage of the vulnerability if they have not already begun attempting to reverse engineer an exploit.\u201d\n\nThere two other publicly disclosed vulnerabilities resolved by Microsoft this month that exist in Common Utilities, found in the NNI open-source toolkit (CVE-2021-31200), and in .NET and Visual Studio (CVE-2021-31204).\n\n\u201cCommon Utilities and .NET and Visual Studio are less likely to be targeted, but due to the public disclosures they should not be ignored for long,\u201d Goettl added.

The CVE-2021-31955 bug \u201cis affiliated with SuperFetch, a feature first introduced in Windows Vista that aims to reduce software loading times by pre-loading commonly used applications into memory,\u201d they explained.\n\nThe second flaw, CVE-2021-31956, is an Elevation of Privilege vulnerability and heap-based buffer overflow. Kaspersky said that attackers used this vulnerability alongside Windows Notification Facility (WNF) \u201cto create arbitrary memory read/write primitives and execute malware modules with system privileges.\u201d\n\n\u201cOnce the attackers have used both the Chrome and Windows exploits to gain a foothold in the targeted system, the stager module downloads and executes a more complex malware dropper from a remote server,\u201d they continued. \u201cThis dropper then installs two executables, which pretend to be legitimate files belonging to Microsoft Windows OS. The second of these two executables is a remote shell module, which is able to download and upload files, create processes, sleep for certain periods of time, and delete itself from the infected system.\u201d\n\nBoris Larin, senior security researcher with Kaspersky\u2019s Global Research and Analysis Team (GReAT), said that the team hasn\u2019t been able to link these highly targeted attacks to any known threat actor: Hence the name PuzzleMaker and the determination to closely monitor the security landscape \u201cfor future activity or new insights about this group,\u201d he was quoted as saying in the press release.\n\nIf the current trend is any indication, expect to see more of the same, Larin said. \u201cOverall, of late, we\u2019ve been seeing several waves of high-profile threat activity being driven by zero-day exploits,\u201d he said. \u201cIt\u2019s a reminder that zero days continue to be the most effective method for infecting targets. Now that these vulnerabilities have been made publicly known, it\u2019s possible that we\u2019ll see an increase of their usage in attacks by this and other threat actors. That means it\u2019s very important for users to download the latest patch from Microsoft as soon as possible.\u201d CVE-2021-31199/CVE-2021-31201The two Enhanced Cryptographic Provider Elevation of Privilege vulnerabilities are linked to the Adobe Reader bug that came under active attack\u00a0last month (CVE-2021-28550), ZDI explained. \u201cIt\u2019s common to see privilege escalation paired with code execution bugs, and it seems these two vulnerabilities were the privilege escalation part of those exploits,\u201d he explained. \u201cIt is a bit unusual to see a delay between patch availability between the different parts of an active attack, but good to see these holes now getting closed.\u201d CVE-2021-33739Breen noted that privilege escalation vulnerabilities such as this one in the Microsoft DWM Core Library are just as valuable to attackers as RCEs. \u201cOnce they have gained an initial foothold, they can move laterally across the network and uncover further ways to escalate to system or domain-level access,\u201d he said. \u201cThis can be hugely damaging in the event of ransomware attacks, where high privileges can enable the attackers to stop or destroy backups and other security tools.\u201d\nSource: threatpost.com (Click Link)Recent News* https://www.blackhatethicalhacking.com/wp-content/uploads/2021/06/Untitled-design-1-1-90x90.png RockYou2021: largest password compilation of all time leaked online \u2013 8.4 billion entries17 hours ago\n* https://www.blackhatethicalhacking.com/wp-content/uploads/2021/06/microsoft-exploit-90x90.jpg Windows Container Malware Targets Kubernetes Clusters1 day ago\n* https://www.blackhatethicalhacking[...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-02T01:03:13.285957Z"}, {"uuid": "1a0a1167-8e73-4c01-b348-08309bd92354", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-31199", "type": "seen", "source": "https://t.me/hacking_Attack/12055", "content": "nt.

The Zero Day Initiative\u2018s (ZDI\u2019s) Dustin Childs noted in his Patch Tuesday analysis that since the vulnerability is in the Trident (MSHTML) engine itself, many different applications are affected, not just Internet Explorer. \u201cIt\u2019s not clear how widespread the active attacks are, but considering the vulnerability impacts all supported Windows versions, this should be at the top of your test and deploy list,\u201d he recommended.\n\nThe vulnerability doesn\u2019t require special privilege to exploit, though the attack complexity is high, if that\u2019s any consolation. An attacker would need to do some extra legwork to pull it off, noted Satnam Narang, staff research engineer at Tenable, in an email to Threatpost on Tuesday.\n\nImmersive Labs\u2019 Kevin Breen, director of cyber threat research, noted that visiting a website in a vulnerable browser is \u201ca simple way for attackers to deliver this exploit.\u201d He told Threatpost via email on Tuesday that since the library is used by other services and applications, \u201cemailing HTML files as part of a phishing campaign is also a viable method of delivery.\u201d Sophos decreed\u00a0this one to be the top concern of this month\u2019s crop, given that it\u2019s already being actively exploited by malicious actors. See Also: Jeff Moss, aka Dark Tangent, the person who founded DEF CON and Black Hat CVE-2021-31955, CVE-2021-31956: Used in PuzzleMaker Targeted MalwareCVE-2021-31955 is an information disclosure vulnerability in the Windows Kernel, while CVE-2021-31956 is an elevation of privilege vulnerability in Windows NTFS. The ZDI\u2019s Childs noted that CVE-2021-31956 was reported by the same researcher who found CVE-2021-31955, an information disclosure bug also listed as under active attack. They could be linked, he suggested: \u201cIt\u2019s possible these bugs were used in conjunction, as that is a common technique \u2013 use a memory leak to get the address needed to escalate privileges. These bugs are important on their own and could be even worse when combined. Definitely prioritize the testing and deployment of these patches.\u201d\n\nHe was spot-on. On Tuesday, Kaspersky announced that its researchers had discovered a highly targeted malware campaign launched in April against multiple companies, in which a previously unknown threat actor used a chain of Chrome and Windows zero-day exploits: Namely, these two.\n\nIn a press release, Kaspersky said that one of the exploits was used for RCE in the Google Chrome web browser, while the other was an elevation of privilege exploit fine-tuned to target \u201cthe latest and most prominent builds\u201d of Windows 10.\n\n\u201cRecent months have seen a wave of advanced threat activity exploiting zero-days in the wild,\u201d according to the release. \u201cIn mid-April, Kaspersky experts discovered yet a new series of highly targeted exploit attacks against multiple companies that allowed the attackers to stealthily compromise the targeted networks.\u201d\n\nKaspersky hasn\u2019t yet found a connection between these attacks and any known threat actors, so it\u2019s gone ahead and dubbed the actor PuzzleMaker. It said that all the attacks were conducted through Chrome and used an exploit that allowed for RCE. Kaspersky researchers weren\u2019t able to retrieve the code for the exploit, but the timeline and availability suggests the attackers were using the now-patched CVE-2021-21224\u00a0[...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-02T01:03:13.762203Z"}, {"uuid": "de0ed9f9-5bf3-4a3b-ad24-81bcda3185b8", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-31194", "type": "seen", "source": "https://t.me/hacking_Attack/8311", "content": "is impacted as well. Definitely put this on the top of your test-and-deploy list.\u201d CVE-2021-26419This second critical bug affecting Microsoft\u2019s legacy browser allows RCE, and offers several avenues of attack, according to researchers.\n\n\u201cIn a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website,\u201d explained Feldman. \u201cAn attacker could also embed an ActiveX control marked \u2018safe for initialization\u2019 in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.\u201d\nSee Also: Offensive Security Tool: EyeWitness The best way to counteract this bug is ditching IE, noted Breen.\n\n\u201cInternet Explorer needs to die \u2013 and I\u2019m not the only one that thinks so,\u201d he told Threatpost. \u201cIf you are an organization that has to provide IE11 to support legacy applications, consider enforcing a policy on the users that restricts the domains that can be accessed by IE11 to only those legacy applications. All other web browsing should be performed with a supported browser.\u201d CVE-2021-31194The third critical bug exists in the Microsoft Windows OLE Automation, which in and of itself should place it on the priority-patch list, according to researchers.\n\n\u201cTo exploit the vulnerability, an attacker could host a specially crafted website designed to invoke OLE automation through a web browser,\u201d explained Justin Knapp, Automox researcher. \u201cHowever, this approach requires that the attacker bait a user into visiting the maliciously crafted website.\u201d\n\nHe pointed out that OLE technology has frequently been used to mask malicious code within documents and for linking to external files that infect systems with malware.\n\n\u201cIn 2020, the CISA released an alert detailing the top 10 routinely exploited vulnerabilities, which identified Microsoft\u2019s OLE as the most commonly exploited technology by state-sponsored cyber-actors,\u201d he said. \u201cConsidering the prevalent exploitation of OLE vulnerabilities, including those that had been flagged years ago, organizations should immediately prioritize patching all outstanding OLE vulnerabilities.\u201d See Also: Hacking Stories: Xbox UndergroundCVE-2021-28476The last critical bug is found in Windows Hyper-V, which is a native hypervisor that can create and run virtual machines on x86-64 systems running Windows. It can allow an attacker to execute arbitrary code, Knapp said:\u00a0\u201cTo exploit this vulnerability, an attacker could run a specially crafted application on a Hyper-V guest that could cause the Hyper-V host operating system to execute arbitrary code when it fails to properly validate vSMB packet data. Successful exploitation could enable an attacker to run malicious binaries on Hyper-V virtual machines or execute arbitrary code on the host system itself.\u201d\n\nThat said, Microsoft noted that an attacker is more likely to abuse the bug for DoS attacks in the form of a system crash rather than RCE, Childs pointed out, which mitigates the vulnerability\u2019s CVSS score of 9.9.\n\n\u201cBecause of this, it could be argued that the attack complexity would be high, which changes the CVSS rating to 8.5,\u201d he said. \u201cThat still rates as high-severity, but not critical. Still, the bug check [system crash] alone is worth making sure your Hyper-V systems get this update.\u201d Publicly Disclosed VulnerabilitiesChris Goettl, senior director of product management at Ivanti, told Threatpost that the biggest patching priority should be the publicly disclosed bugs \u2013 even though there is as yet no known malicious exploitation.\n\n\u201cThe top concern from the Microsoft updates this month is the update for Microsoft Exchange that[...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-02T01:03:19.163724Z"}, {"uuid": "fe262a2d-b3ab-478f-a53f-33b491a762b1", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2021-31194", "type": "seen", "source": "https://t.me/hacking_Attack/8310", "content": "Black Hat Ethical Hacking\nWormable Windows Bug Opens Door to DoS, RCE\n\nhttps://www.blackhatethicalhacking.com/wp-content/uploads/2017/11/black-hat-locks-and-electronics.jpg Wormable Windows Bug Opens Door to DoS, RCEPost Views: 89 \nReading Time: 2 Minutes\nMicrosoft\u2019s May 2021 Patch Tuesday updates include fixes for four critical security vulnerabilities, including a\u00a0patch for a concerning wormable vulnerability found in the Windows OS.\nThe good news is that none of the vulnerabilities are being actively exploited in the wild, according to Microsoft, though three are listed as publicly known. The fixes\u00a0address security flaws across Microsoft Windows, .NET Core and Visual Studio, Internet Explorer (IE), Microsoft Office, SharePoint Server, Open-Source Software, Hyper-V, Skype for Business and Microsoft Lync, and Exchange Server. Besides the four critical bugs, 50 are rated \u201cimportant\u201d and one is moderate in severity. Critical Microsoft Security Patches for May 2021The critical bugs in this month\u2019s Patch Tuesday release are:\n\n* CVE-2021-31166: A wormable HTTP protocol-stack issue in Windows 10 and some versions of Windows Server allowing remote code-execution (RCE)\n* CVE-2021-26419: A scripting-engine memory corruption vulnerability in Internet Explorer 11 and 9 allowing RCE\n* CVE-2021-31194: An RCE bug in the Microsoft Windows Object Linking and Embedding (OLE) Automation\n* CVE-2021-28476: An RCE vulnerability in Microsoft Windows Hyper-V CVE-2021-31166 \u2013 WormableThis most concerning critical bug for researchers is an HTTP protocol-stack issue that would allow RCE with kernel privileges or a denial-of-service (DoS) attack. The HTTP protocol stack enables Windows and applications to communicate with other devices; it can be run standalone or in conjunction with Internet Information Services (IIS).\n\n\u201cIf exploited, this vulnerability could enable an unauthenticated attacker to send a specially crafted packet to a targeted server utilizing the HTTP protocol stack (http.sys) to process packets and ultimately, execute arbitrary code, and take control of the affected system,\u201d Eric Feldman, cybersecurity researcher with Automox, wrote in an analysis.\nSee Also: Lemon Duck Cryptojacking Botnet Changes Up Tactics Worse, Microsoft noted that the bug is wormable, so that it could be used to self-replicate across the internal network and affect internal services that may not have been exposed.\n\n\u201cThe vulnerability announced has the potential to be both directly impactful and is also exceptionally simple to exploit, leading to a remote and unauthenticated DoS (Blue Screen of Death) for affected products,\u201d Steve Povolny, head of advanced threat research and principle engineer at McAfee, said via email. \u201cWhile this vulnerability has the potential to lead to code execution in the Windows kernel, this type of weaponization is a much higher bar for exploitation. However, if RCE can be achieved, cybercriminals would likely have the capability to create a worm, leading to self-propagation of the vulnerability across networks and the internet.\u201d\n\n\u201cFor ransomware operators, this kind of vulnerability is a prime target for exploitation,\u201d Kevin Breen, director of cyber-threat research at Immersive Labs, told Threatpost. \u201cWormable exploits should always be a high priority, especially if they are for services that are designed to be public facing. As this specific exploit would not require any form of authentication, it\u2019s even more appealing for attackers, and any organization using HTTP.sys protocol stack should prioritize this patch.\u201d\n\nDustin Childs, researcher with Trend Micro\u2019s Zero Day Initiative (ZDI), noted in a blog, \u201cBefore you pass this aside, Windows 10 can also be configured as a web server, so it [...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-02T01:03:19.341824Z"}]}
