In mid-March 2025, Kaspersky technologies detected a wave of infections by previously unknown and highly sophisticated malware. In all cases, infection occurred immediately after the victim clicked on a link in a phishing email, and the attackers’ website was opened using the Google Chrome web browser. No further action was required to become infected.
All malicious links were personalized and had a very short lifespan. However, Kaspersky’s exploit detection and protection technologies successfully identified the zero-day exploit that was used to escape Google Chrome’s sandbox. We quickly analyzed the exploit code, reverse-engineered its logic, and confirmed that it was based on a zero-day vulnerability affecting the latest version of Google Chrome. We then reported the vulnerability to the Google security team. Our detailed report enabled the developers to quickly address the issue, and on March 25, 2025, Google released an update fixing the vulnerability and thanked us for discovering this attack.
