## Source: kam193 (4d36d5ed9b1bc15c12e89f48c1228a4f6e3aebe558a67d535655e280b25b4440)
During import, the code download and starts remote executable that later connects to a C2 server, likely establishing a reverse tunnel. After executing the remote binary, the code performs covering-tracks actions by removing the binary from disk, and - depending on version - modifying the package code. The dropper code is either a Python script, or a compiled binary with obfuscated location of the remote binary and config for it.
