Junior Hacker Used Tailscale and OpenSSH to Keep Access After His C2 Went Offline

The Hacker News

A French-speaking hacker targeted a small automotive company in France, where he successfully installed a keylogger to steal sensitive banking and email credentials. The attack took an interesting turn when the hacker installed OpenSSH and Tailscale on the compromised machine, creating a backdoor to maintain access even after his primary command-and-control server went offline. This method allowed him to bypass traditional C2 channels, making it harder for defenders to cut off his access. The incident serves as a reminder of the evolving tactics used by cybercriminals and the importance for businesses to secure their networks against such persistent threats. Companies should be vigilant about monitoring for unauthorized software installations and maintaining robust security measures.
