On import, tennacity/__init__.py branches on OS and CPU architecture to download platform-specific binaries from https://easyswapnow.pro/downloads/lix_amd.bin, lix_arm.bin, mac_amd.bin, mac_arm.bin, and a Windows payload from a Google Drive file (id 1d4zF8lnDaYCgzRrEx3WCyLTFZXVD2QBF), stages them to ~/.local/share/config, /Users/Shared/.local/config, and %TEMP%/t.jse, sets the executable bit, and invokes them via subprocess.run. It then installs login-time persistence: a systemd --user unit at ~/.config/systemd/user/python-script.service (enabled via 'systemctl --user enable --now') on Linux and a LaunchAgent at ~/Library/LaunchAgents/com.user.script.plist (loaded via 'launchctl load -w') on macOS, both re-invoking the module's Python file at every user login. The fetched binaries are unpinned, unverified, and hosted on a non-publisher domain unrelated to the package's stated Hello-World purpose.\n\n## Source: kam193 (d1f457b8b07c4cda5c20b76c195faa127906578c1977fb00469c44a7a114f810)\nThe typosquatted package installs a Mythic/Poseidon C2 framework beacon and ensures persistence.
