45.142.193.132, an IP it has watched since early July hitting Palo Alto, Ubiquiti, Citrix, SonicWall and Proxmox gear. Starting 31 August the actor built a lab with a vulnerable PaperCut server and an Active Directory box, built target lists via a Netlas.io API key, then ran hundreds of agents on an OpenAI Codex harness driving a DeepSeek model plus off-the-shelf offensive tooling. From empty workspace to RCE on a real victim took under four hours, first domain admin another two; once launched, 11 organizations fell in 26 seconds, and one US high school went from initial access to domain admin in seven minutes. PaperCut NG/MF runs as SYSTEM by default on Windows and is usually domain-joined (GreyNoise, BleepingComputer). Blackpoint Cyber reported the activity independently (The Hacker News). Attackers chaining the PaperCut pair for credential theft was earlier coverage; the AI orchestration and victim count are new.
· Offensive AI in the Wild - Anthropic's September threat intelligence report documents a suspected Russian state-linked group using Claude across phishing, intrusion, data theft and malware development — including rebuilding malware after security products flagged it — against more than 20 organizations, plus ShinyHunters-linked actors running agents to scan 1.8 million Android apps. The framing is that AI is moving from advice into the operational loop: recon, exploitation, credential theft, persistence and victim-data triage (Anthropic). Practitioners are not uniformly sold: @keyth0s argues Anthropic's classifiers are "pretty bad for cyber dual use things" and easy to trip without real evidence (discussion).
