Siemens Vulnerability: When Your Smart System Gets a Little Too Smart!
Siemens APOGEE PXC and TALON TC Series devices have a vulnerability causing unsolicited BACnet broadcasts, leading to partial denial of service. Siemens suggests protective network measures since no fix is planned. For ongoing security updates, check Siemens ProductCERT Security Advisories. CISA warns to keep these systems off the web—unless you enjoy cyber roulette.

Hot Take:
Siemens’ BACnet devices have taken a liking to unsolicited chatter, and CISA is taking a step back, leaving Siemens to play cybersecurity babysitter. With no fix in sight, it’s like watching a soap opera where the villain just won’t die! Siemens suggests power cycling as the best therapy for these chatty devices, while CISA advises a VPN and a sturdy firewall to keep the gossip in check.
