Rise of Evil LLMs: How AI-Driven Cybercrime Is Lowering Barriers for Global Hackers

As artificial intelligence continues to redefine modern life, cybercriminals are rapidly exploiting its weaknesses to create a new era of AI-powered cybercrime. The rise of “evil LLMs,” prompt injection attacks, and AI-generated malware has made hacking easier, cheaper, and more dangerous than ever. What was once a highly technical crime now requires only creativity and access to affordable AI tools, posing global security risks. 

While “vibe coding” represents the creative use of generative AI, its dark counterpart — “vibe hacking” — is emerging as a method for cybercriminals to launch sophisticated attacks. By feeding manipulative prompts into AI systems, attackers are creating ransomware capable of bypassing traditional defenses and stealing sensitive data.

This threat is already tangible. Anthropic, the developer behind Claude Code, recently disclosed that its AI model had been misused for personal data theft across 17 organizations, with each victim losing nearly $500,000. 

On dark web marketplaces, purpose-built “evil LLMs” like FraudGPT and WormGPT are being sold for as little as $100, specifically tailored for phishing, fraud, and malware generation.

Prompt injection attacks have become a particularly powerful weapon. These techniques allow hackers to trick language models into revealing confidential data, producing harmful content, or generating malicious scripts. 

Experts warn that the ability to override safety mechanis
