Further, they disclosed the details after examining DevilsTongue attacks on their clients.\nCandiru started abusing the zero-day in March and targeting users in Palestine, Turkey, Yemen, and Lebanon.\nThe flaw, tracked as CVE-2022-2294, is a high-severity heap-based buffer overflow in WebRTC. Its successful exploitation may lead to code execution on the targeted device.\nAfter being reported to Google, the tech firm patched the exploited zero-day on July 4, which has been under active exploitation in cyberattacks.\n\nSince the bug exists in WebRTC, it also impacts Safari browser but the exploit found only work on Windows.\n\n*Attack vectors*\n\nThe spyware operators have used watering holes and spear-phishing tactics in their attacks.\nThis attack requires no interaction with the victim, such as clicking on a link or downloading a file. \nInstead, a user is made to open an already compromised website or the one created by hackers in a Chromium-based browser or Chrome. \nIn one instance, the attackers infected a website used by a news agency in Lebanon and inserted JavaScript snippets to enable XSS attacks, and redirected targets to the exploit server.\nIn the Lebanon case, the zero-day allowed shellcode execution inside a renderer process and further chained with a sandbox escape flaw that Avast failed to recover for investigation.\n\n*What was the target?*\n\nAfter the initial infection, the DevilsTongue spyware used a BYOVD (bring your own driver) step to elevate the privileges and achieve read and write rights to the infected device's memory. Researchers believe the cybercriminals used the spyware to learn about what news stories the targeted journalist are working on.\n\n*Conclusion*\n\nThe recent report sheds light on the dangers of services offered by commercial spyware vendors. These vendors are developing or buying zero-day exploits to target people asked by their clients. Thus, always protect data with powerful encryption and update devices with the latest security updates.", "creation_timestamp": "2022-07-30T13:19:16.000000Z"}
