In mid-March 2025, Kaspersky technologies detected a wave of infections by previously unknown and highly sophisticated malware.

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. Kaspersky researchers 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, which was then reported to the Google security team.
