Researchers have discovered that 100 Chrome extensions, published through five different accounts, are part of a coordinated campaign designed to steal user data and create backdoors. These malicious extensions utilize shared command and control (C&C) infrastructure, indicating a well-organized effort by the attackers. Users who have installed these extensions are at risk of having their data compromised, which could lead to identity theft or other forms of online fraud. This incident serves as a reminder for users to be cautious when installing browser extensions and to regularly review their installed add-ons for any suspicious activity. The findings underscore the need for enhanced scrutiny of browser extensions to protect user privacy and security.
