Seriously? Akira’s Bypassing MFA on SonicWall VPNs.
Oh, joy. More security theater falling apart. The Akira ransomware group is apparently waltzing through supposedly secure SonicWall VPN accounts with multi-factor authentication enabled. How? Some zero-day vulnerabilities in the SMA 100 series VPN appliances, naturally. Because *of course* it’s a zero-day. It’s always a fucking zero-day.
They’re exploiting these holes to steal credentials and then use those to encrypt systems. SonicWall is patching (eventually), but the damage is already done. They’ve been at this since August, so if you’re running one of these ancient boxes, assume you’re compromised. And don’t even *think* about relying on MFA as a silver bullet – it clearly isn’t.
The affected versions are SMA 100 series before 9.2.4.5 and 10.0 series before 10.0.7.3. Update your shit, people! Or better yet, rip those SonicWall things out and use something that isn’t constantly leaking like a sieve. But hey, who am I to tell you what to do? Just sit there and get owned, apparently.
And for the love of all that is holy, check your logs. Look for suspicious activity. Though honestly, at this point, it’s probably easier to just rebuild everything from scratch.
Related Anecdote: I once had a sysadmin tell me MFA was “unbreakable.” Three weeks later, he was begging me to help him recover from a phishing attack that bypassed it. Unbreakable, my ass. People are stupid. Systems are flawed. Expect failure. Always.
