Google Chrome’s Zero-Day Drama: Trinper Backdoor Hits Russian Targets!
Google Chrome recently patched a flaw that TaxOff exploited as a zero-day to deploy the Trinper backdoor. The attack began with a phishing email disguised as a forum invite, leading to a sandbox escape vulnerability. Trinper’s multithreading allows for stealth and efficient data capture, while its command server extends its capabilities.

Hot Take:
Google Chrome’s security flaw was like leaving the door open with a welcome mat saying “Hackers Welcome!” But don’t worry, the cavalry arrived, wearing Google’s armor, to patch the breach and kick out the unwelcome guests. Meanwhile, TaxOff and their Trinper backdoor were too busy playing hide and seek with sensitive information to notice they were being evicted. Lesson learned: don’t click on suspicious links, unless you enjoy unexpected digital guests!
Key Points:
- TaxOff exploited a Google Chrome zero-day vulnerability to deploy the Trinper backdoor.
- The attack was executed via phishing emails disguised as event invitations.
- The Trinper backdoor, written in C++, used multithreading for stealthy operations.
- Positive Technologies linked the attack to similar campaigns dating back to 2024.
- The hacking techniques share similarities with another group, Team46, suggesting a possible connection.
