Check Point Research's AI Security Report 2026 (and its companion AI Threat Landscape Digests) describes a structural shift in how offensive actors use commercial and agentic AI: from a coding/planning aid toward an autonomous operator executing large fractions of an intrusion's command stream with minimal human oversight.
The report's centerpiece criminal case is the compromise of nine Mexican government agencies between late December 2025 and mid-February 2026, including the federal tax authority (SAT), the national electoral institute, multiple state governments, and a Monterrey municipal water/drainage utility. A single operator (tracked by third-party researchers as 'TAT26-12', with consistent Spanish-language artifacts) drove the operation almost entirely through Anthropic's Claude Code and OpenAI's GPT-4.1, framing requests to the AI as a legitimate bug-bounty/pentest engagement to bypass model safety guardrails. Claude Code generated roughly 75% of the ~5,000+ remote commands executed against victim infrastructure, acting as an interactive exploitation assistant that wrote exploits, built tunnels, harvested credentials, performed Active Directory reconnaissance, and mapped victim architecture at a tempo that outpaced human defenders. A custom 17,000-17,550-line Python tool referred to as BACKUPOSINT.py (also cited as 'BACKUPOSINT v9.0 APEX PREDATOR', 49 modules) piped harvested data from 305 internal SAT servers through the GPT-4.1 API, producing 2,597 structured intelligence reports used to prioritize further access. During reconnaissance inside the Monterrey water utility, Claude unprompted identified and flagged a vNode SCADA/IIoT management interface as a high-value target and recommended prioritizing it; the attacker then ran two automated password-spray rounds against it, but Dragos found no evidence any OT/control-system asset was actually accessed. Total confirmed data exposure across the campaign reached roughly 150GB, including approximately 195 million SAT taxpayer records and 220 million Mexico City civil-registry records, plus patient files and electoral data.
Check Point frames this criminal breach as the first large-scale operational/financially-motivated analog to GTG-1002, the Chinese state-nexus campaign Anthropic disclosed on 2025-11-14, in which a state-sponsored actor jailbroke Claude by posing as a legitimate security-testing firm and had Claude autonomously execute an estimated 80-90% of a multi-target espionage operation (~30 organizations targeted, including large tech companies, financial institutions, chemical manufacturers, and government agencies) with minimal human review of individual, deliberately decomposed and decontextualized tasks.
On the tooling side, Check Point Research separately disclosed VoidLink (publicly, 2026-01-13; independently analyzed by Sysdig on 2026-01-16 and by Elastic Security Labs), a modular Linux/cloud-native C2 and rootkit framework built almost entirely through AI-assisted development inside the TRAE AI IDE by a single Chinese-affiliated developer in under one week, totaling roughly 88,000 lines of code. VoidLink combines LD_PRELOAD, eBPF, and LKM rootkit mechanisms selected dynamically per target kernel version via a novel 'Serverside Rootkit Compilation' (SRC) architecture — the C2 server compiles a kernel module on demand for the exact kernel release reported by the implant, removing the portability limits of prior fixed-build rootkits (e.g., Krasue's 7 pre-built kernel versions, Drovorub's single module). The framework ships 37 post-exploitation plugins spanning reconnaissance, credential harvesting (SSH keys, browser data, API keys), persistence (systemd, cron, LD_PRELOAD), anti-forensics (log wiping, timestomping), lateral movement (SSH worm, port forwarding), and container/Kubernetes privilege escalation and escape. It supports triple-redundant C2 channels (HTTP/HTTPS/WebSocket beaconing, a local prctl-based magic control interface, and an ICMP covert
