Two nights ago, an anonymous upload had appeared in the police network: a single string of code titled UPD_PATCH.exe. It claimed to fix a vulnerability that allowed a coordinated blackout to be triggered remotely. The city IT chief had been skeptical; within hours the patch had been run on several critical nodes by a contractor with no verifiable identity. By morning, one ward was already without power. By noon, two hospitals reported failing UPS systems. By evening, the anonymous patch had proven malicious.
