Giant leak reveals Chinese infosec vendor I-Soon is one of Beijing's cyber-attackers for hire

Leaked documents posted to GitHub reportedly from Chinese infosec vendor I‑Soon detail a hacking‑for‑hire operation that bids for government work, claims tools to compromise Linux, Windows, macOS, iOS and Android, and describes hardware hacking (e.g., a poisoned power bank) and data exfiltration capabilities; analysts view the trove as valuable insight into China’s outsourced offensive ecosystem but find no clear evidence of unique zero‑day capabilities or confirmed widescale exploitation so far.
