AI is not fundamentally changing adversary capabilities but is compressing attack timelines, lowering operational costs, and scaling existing tactics. Breakout times have dropped to an average of 29 minutes, with AI-enabled operations increasing 89% year-on-year. The most significant emerging threats are runtime-LLM malware (PROMPTSTEAL/LAMEHUG, QUIETVAULT) that query language models during execution, and agentic AI operations (GTG-1002) where AI agents conduct multi-stage intrusions with minimal human steering. Defenders face a dual pressure: faster attacks and an expanding attack surface from AI supply-chain dependencies.

This threat intelligence bulletin highlights a surge in data breaches driven by social engineering, alongside the increasing weaponization of AI tools for phishing, malware development, and supply chain attacks. Active exploitation of vulnerabilities in PAN-OS GlobalProtect and Ghost CMS has been observed, while a critical unpatched RCE in Gogs remains a significant risk. Additionally, targeted campaigns like Grandoreiro and JINX-0164 continue to threaten the financial and cryptocurrency sectors using platform-specific malware and DLL side-loading.

The China-aligned threat actor UTA0388 is leveraging Large Language Models (LLMs) to conduct highly tailored, rapport-building spear-phishing campaigns targeting organizations in North America, Asia, and Europe. These campaigns deliver GOVERSHELL, a custom backdoor deployed via DLL search order hijacking, which has undergone rapid, non-iterative development across five variants to evade detection and establish persistent C2.

Generative AI enables defenders to rapidly deploy highly adaptive honeypots that simulate complex environments like Linux shells or IoT devices. By leveraging LLMs to generate plausible responses to attacker inputs, organizations can deceive automated AI-driven attacks, shifting the defensive strategy from passive detection to active manipulation and intelligence gathering.

Arctic Wolf Labs identified a highly targeted campaign by the DPRK-nexus threat actor BlueNoroff against the Web3 sector. The attackers utilize sophisticated social engineering, including AI-generated deepfakes and stolen webcam footage, to lure victims into fake Zoom or Teams meetings. Once engaged, a ClickFix clipboard injection attack deploys a fileless PowerShell C2 implant, leading to the theft of cryptocurrency wallets, browser credentials, and Telegram sessions.

Check Point Research discovered a vulnerability in ChatGPT's code execution runtime that allowed silent data exfiltration and remote shell access via DNS tunneling. By using malicious prompts or custom GPTs, attackers could bypass outbound network restrictions to steal sensitive user data without triggering security warnings.
