Meet the Brains Behind the Malware-Friendly AI Chat Service ‘WormGPT’

Summary: WormGPT, a private chatbot advertised on HackForums as an uncensored alternative to ChatGPT for writing malware, has begun restricting topics including ransomware, financial crime, and BEC after customers used it for those purposes. Its creator, a 23-year-old Portuguese programmer who goes by "Last" and was identified as Rafael Morais, says roughly 200 customers have paid for licenses priced from 500 to 5,000 Euro, and that only about 30 to 35 percent of the work is his.

What's compelling: A service built and sold explicitly for cybercrime drew about 200 paying customers before its operator started adding guardrails, and he still claims on HackForums and Exploit that WormGPT will produce Rust malware "99% sure" to be fully undetectable by most antivirus products.
