โ ๏ธ Targeting the US and Canada, the chain starts on a compromised WordPress site and ends with a WinHTTP stager running inside a signed Microsoft executable. A user-driven lure becomes trusted-process C2 activity that can evade early validation and slow containment.
โ๏ธ Key evasion detail: binaries are stored as English word sequences inside JavaScript code, executed by a legitimate Node.js runtime downloaded to the host. Fixed vocabularies decode them into payloads that look like ordinary text, not executable content.
๐ Lure domains come from a Polygon smart contract, and the final C2 list is pulled from a public forum profile before beaconing.
๐จโ๐ป Static checks only show part of the chain, making real business exposure harder to assess.
