Siemens BACnet Vulnerability: When Your Network Throws a DoS Party!
As of January 10, 2023, Siemens BACnet ATEC devices have a vulnerability that could lead to a denial-of-service attack. While CISA won’t update advisories, Siemens suggests securing network access. For the latest info, check Siemens’ ProductCERT Security Advisories. Remember, a power cycle a day keeps the denial of service away!

Why bother updating your ICS security advisories when you can just “Siemens” your way out of it?

So, if you’re in the “denial of service” business, pack your bags and move to a BACnet network near you! But remember, Siemens advises you to protect your devices as if they’re the last cookie in the jar. Stay safe, or at least stay entertained while your network goes down in style!
