SonicWall Snafu: Hackers Hijack VPNs with Crafty Backdoor Shenanigans!
Unknown miscreants are having a field day with end-of-life SonicWall VPNs, deploying a new backdoor and rootkit called OVERSTEP. While the devices are patched, these digital Houdinis still wriggle in, stealing credentials and leaving no trace. The attack has data theft and extortion written all over it.

Hot Take:
Why do these cybercriminals have to be like raccoons? Always rummaging through our virtual trash cans, looking for tasty bits of data to steal. And what’s with the backdoor and rootkit? It’s like they’re house-sitting our networks and leaving the place a mess! Maybe it’s time we start treating our cybersecurity like a “no trespassing” sign instead of an “open house” invitation.
Key Points:
- SonicWall VPNs, despite being fully patched, are under attack by cybercriminals using a backdoor called OVERSTEP.
- The attackers, known as UNC6148, are exploiting vulnerabilities and possibly even zero-day flaws.
- The malware allows persistent access, data theft, and concealment of malicious activities.
- Google’s Threat Intelligence Group is on the case, urging users to check for indicators of compromise.
- There’s a potential link to ransomware activities, though it’s not confirmed.
