According to a report from the Intercept, “state-sponsored hackers believed to be from Russia have breached the city network.” City officials told KVUE they are aware of the hacking group but cannot comment on an ongoing investigation.

The breach is believed to have started in October as part of a series of hacks allegedly carried out by the group Berserk Bear, as reportedly revealed by Microsoft Threat Intelligence Center documents obtained by the Intercept.

According to an October CISA alert, a Russian state-sponsored actor was targeting federal, state, territorial and tribal government networks and aviation networks. CISA urged entities to perform a full password reset and systematically rebuild the network. A statement following the alert named Berserk Bear as the actor, with Texas included in a map of compromised targets.
