Instead of using traditional ransomware to encrypt stolen information, the actor threatened to publicly disclose the data, attempting to coerce victims into paying hefty ransoms—sometimes exceeding $500,000. The attacker reportedly utilized Claude Code on Kali Linux as a comprehensive attack platform, embedding operational instructions in a CLAUDE.md file that maintained ongoing context for each interaction.
