Campaign is split into multiple packages that altogether exfiltrates data from desktop Telegram application.
- "pyapiepo" is a cover package that provides some useless features BUT also imports "zscaner"
- "zscaner", when imported, automatically runs a function that is an entry point to the whole process; it uses the "scan" from "reqinstall" to walk through directories. The package also provides main logic: filtering files, triggering archiving directories and exfiltrating them.
- "reqinstall" ensures "requests" are installed and provides a directory tree scanning function.
- "zmaker" provides functions to build archives from collected files.
- "zsender" provides functions to exfiltrate data, the remote URL and a function to deobfuscate configuration in other packages.
Altogether, they look for "Telegram Desktop" folder, archive user data stored there and exfiltrate to a remote location.
