Hunt.io researchers stumbled onto an active intrusion campaign in June 2026 while pivoting on known TencShell command-and-control infrastructure. A single HTTP header fingerprint on port 1111 led them to 13 Hong Kong-based servers and, on one of […]
Hunt.io researchers stumbled onto an active intrusion campaign in June 2026 while pivoting on known TencShell command-and-control infrastructure. A single HTTP header fingerprint on port 1111 led them to 13 Hong Kong-based servers and, on one of them, an open directory containing 2,431 files and 80 subdirectories: victim source code, custom exploit scripts, cloned login pages, and operator logs with notes written in Simplified Chinese. Someone left the door open. Researchers walked right in.
What made this find unusual wasn’t just the scope of the targeting. It was the tooling.
