Admins are being cautiousAs BleepingComputer reported\u00a0last week, after the proof-of-concept exploit code for CVE-2021-26084 became public, threat actors started to scan for vulnerable Atlassian Confluence instances to install cryptocurrency miners.\n\nWhile many attackers used the exploit to install the open-source, cross-platform XMRig Monero cryptocurrency miner, they could also leverage the vulnerability for more damaging attacks.\n\nLast week, administrators of the Jenkins project discovered that one of their deprecated Confluence server fell victim to one of these attacks.\nSee Also: Complete Offensive Security and Ethical Hacking Course \u201cThus far in our investigation, we have learned that the Confluence CVE-2021-26084 exploit was used to install what we believe was a Monero miner in the container running the service. From there an attacker would not be able to access much of our other infrastructure\u201d \u2013 Mark Waite, Jenkins Documentation Officer\nAlthough there is no evidence suggesting that the attacker stole developer credentials, Jenkins project managers are being careful and have reset passwords for all accounts in the integrated identity system that also included the deprecated Confluence service.\n\nThe admins also said that they \u201care taking actions to prevent releases at this time until we re-establish a chain of trust with our developer community.\u201d The affected Confluence service is no longer active and privileged credentials have been rotated.\n\nCVE-2021-26084 is a remote code execution vulnerability in Atlassian Confluence that can be exploited without authentication. News about it emerged on August 25, when the company published a security advisory.\nSee Also: Critical Valve Bug Lets Gamers Add Unlimited Funds to Steam Wallets\nAbout a week later, technical details became publicly available along with proof-of-concept exploit code. Threat actors started leveraging so heavily that the U.S. Cyber Command (USCYBERCOM) issued a warning\u00a0about mass exploitation.\nhttps://www.bleepstatic.com/images/news/u/1100723/2021/USCyberComConfluence.jpg \n<figcaptionsource: USCYBERCOM \nSee Also: Offensive Security Tool: Pegasus Spyware \u2013 Decompiled See Also: Hacking Stories: Andrian Lamo \u2013 The \u2018homeless\u2019 HackerSource: www.bleepingcomputer.com (Click Link)Recent News* https://www.blackhatethicalhacking.com/wp-content/uploads/2021/09/unnamed-e1630998483665-90x90.jpg Critical Auth Bypass Bug Affect NETGEAR Smart Switches1 day ago\n* https://www.blackhatethicalhacking.com/wp-content/uploads/2021/09/loyalty-card-90x90.jpg Brute-Force Attacks Target Inboxes for Gift Card Data2 days ago\n* https://www.blackhatethicalhacking.com/wp-content/uploads/2021/09/Braktooth-New-Bluetooth-gaps-threaten-countless-devices-1024x576-1-90x90.jpg Bluetooth Bugs Open Billions of Devices to DoS, Code Execution5 days ago\n* https://www.blackhatethicalhacking.com/wp-content/uploads/2021/09/wordpress_plugin_vuln-90x90.jpg Gutenberg Template Library & Redux Framework Bugs Plague WordPress Sites6 days ago\n* https://www.black[...]", "creation_timestamp": "2026-09-01T20:02:25.255003Z"}
