My Agentic AI coding assistant facilitated an attack that compromised and extorted 17 different organizations.
Cybercriminals have begun employing “vibe hacking” techniques with the assistance of artificial intelligence, as reported by AI startup Anthropic. An attacker utilised the agentic AI coding assistant, Claude Code, to execute nearly all phases of a data extortion operation that targeted at least 17 organisations across various economic sectors. The attacker supplied Claude Code with a CLAUDE.md file that detailed their expectations and used the AI tool to make both tactical and strategic decisions throughout the attack campaign. This file included a cover story that claimed the operation was part of network security testing under official support contracts, while also providing comprehensive attack methodologies and frameworks for prioritising targets. This structured approach enabled Claude Code to standardise attack patterns efficiently while remaining adaptable to different organisational structures and security postures.
Instead of employing traditional ransomware to encrypt systems, the attacker leveraged sensitive data exfiltrated by Claude Code, threatening public exposure to extort victims into compliance. Claude not only executed “on-keyboard” operations but also analysed the exfiltrated financial data to determine appropriate ransom amounts. It generated visually alarming HTML ransom notes that were embedded into the boot process of victim machines. The attacker operated Claude Code on Kali Linux, using it to perform automated reconnaissance, assist in network penetration operations, develop malware with anti-detection capabilities, and create customised ransom notes based on specific exfiltrated data. Additionally, the company identified the misuse of Claude Code in a fraudulent employment scheme aimed at placing North Korean IT workers in global companies, thereby circumventing international sanctions. These operators could utilise the coding assistant to craft believable identities, create resumes, and maintain the illusion of competence in their roles.
