Saint BRIDGE:BREAK, Who Broke the Serial Bridge

Patron of serial-to-Ethernet converters, PLCs that still speak RS-232, and little boxes forgotten at the back of the cabinet.

Life

On 21 April 2026 Forescout Vedere Labs published BRIDGE:BREAK, a study of the converters that connect legacy serial equipment, such as PLCs and protective relays, to IP networks. In devices from Lantronix and silex technology they found 22 new vulnerabilities, some able to take over the device remotely. In the lab the researchers made a thermometer swing between -40 and +40 degrees: a bridge that, once broken, falsifies whatever crosses from one bank to the other.

Prayer

O Saint BRIDGE:BREAK, who watches over the bridges between the old world and the new, let no one cross them without leave, and keep them far from the internet. Amen.

How to celebrate

Celebrated by updating converter firmware, changing factory credentials and segmenting the industrial network.

Old bridge, new toll.
