Unmasking I-Soon | The Leak That Revealed China’s Cyber Operations

**Unmasking I-Soon**: Leaked internal documents from I‑Soon (a PRC-affiliated hacking contractor) reveal marketing materials, client targeting lists, employee chats, technical documentation for offensive tools (including custom hardware and malware/C2 details), and claimed compromises of governments, pro‑democracy groups, universities, and NATO; the trove offers rare visibility into China's contractor-driven cyber‑espionage ecosystem, complicates attribution, and highlights both operational tradecraft and risks to defenders.
