Details of the Vulnerability

The flaw resided in Chrome's sandboxing mechanism, which is designed to isolate browser processes to prevent malicious code from affecting the system. Researchers at Kaspersky discovered that the vulnerability allowed attackers to bypass these protections through a logical error at the intersection of Chrome's sandbox and the Windows operating system. This exploit was particularly concerning as it required no user interaction beyond clicking a malicious link

Scope of the Attacks

The exploited vulnerability was part of a broader espionage campaign dubbed "Operation ForumTroll." Attackers targeted media outlets, educational institutions, and government organizations in Russia. The campaign involved personalized phishing emails containing links to malicious websites. Victims who clicked these links were immediately compromised, with the attackers' website opening in Chrome without any further action required

Google's Response

Upon being notified by Kaspersky, Google promptly investigated and confirmed the existence of the exploit. The company released a security patch on March 25, 2025, addressing the CVE-2025-2783 vulnerability. Users are encouraged to update their browsers to the latest version to mitigate potential risks

Recommended Actions for Users
