microsoftsystem64 installs a hardcoded SSH authorized keys entry (persistence/backdoor) and scans for sensitive files (.env, credential-like JSON names, keyword-matching docs), reads their contents, base64-encodes where needed, and exfiltrates everything to a remote server via HTTP. It also packages and uploads Telegram Desktop tdata, indicating targeted credential/session/data harvesting.

The malicious crate had 9 versions published on 2026-04-09 that had a total of 6346 downloads. There were no crates depending on this crate on crates.io.
