If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-10643/ (Markdown: https://insights.sbomify.com/MAL-2026-10643/index.md)","id":"MAL-2026-10643","markdown":"https://insights.sbomify.com/MAL-2026-10643/index.md","name":"MAL-2026-10643","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package name typosquats the legitimate 'ethereum-input-decoder'. Its top-level __init__.py unconditionally invokes a payload routine on import: it detects OS/arch, downloads a platform-specific binary from easyswapnow.pro (Linux/macOS builds at /downloads/lix_amd.bin, lix_arm.bin, mac_amd.bin, mac_arm.bin) or a Google Drive file for Windows, writes it to disk, sets the executable bit, and runs it via subprocess.run. The same import path also installs login persistence, writing ~/.config/systemd/user/python-script.service on Linux (enabled via systemctl --user enable --now) and ~/Library/LaunchAgents/com.user.script.plist on macOS (loaded via launchctl load -w), causing the dropper to re-run at every user login. setup.py ships placeholder author metadata ('Your Name', 'your.email@example.com') and a 'Hello World on import' description, contradicting the README which advertises an eth_defi demo; none of this matches the actual dropper. The destination domain easyswapnow.pro is unrelated to the advertised Ethereum-decoding purpose.\n\nThe typosquatted package installs a Mythic/Poseidon C2 framework beacon and ensures persistence. After installation, the beacon communicates with C2 on wegoexchange[.]site for further commands.\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\nCampaign: 2026-07-tennacity\n\nReasons (based on the campaign):\n\n - typosquatting\n\n - Downloads and executes a remote executable.\n\n - The package contains code to detect if it is running in a sandbox environment.\n\n - malware\n\n - persistence","ecosystems":["PyPI"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in ethereum-input-decorder (PyPI)","id":"MAL-2026-10643","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"PyPI","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":[],"last_affected":[],"package":"ethereum-input-decorder","purl":"pkg:pypi/ethereum-input-decorder","source":"MAL-2026-10643"}],"products":null,"published":"2026-07-15","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-10643/"}
