Advisory PublishedCVSS 9.6/10
The file `e.py` implements a textbook data-theft pipeline: it creates a ZIP archive via `shutil.make_archive` from a target folder path (likely staging sensitive files from the filesystem), then immediately POSTs the archive to a Cloudflare Worker endpoint via `requests.post(WORKER_URL, files=...)`. The Russian-language comments embedded in the code — '[+] The archive was successfully created in Temp' and '[*] Sending the archive to Cloudflare Worker...' — confirm the author's intent is to exfiltrate data to an attacker-controlled backend proxied through Cloudflare. This is the classic attacker pattern of using Cloudflare Workers as a C2/exfil relay to obscure the true destination.
