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-2026-15859/ (Markdown: https://insights.sbomify.com/MAL-2026-15859/index.md)","id":"MAL-2026-15859","markdown":"https://insights.sbomify.com/MAL-2026-15859/index.md","name":"MAL-2026-15859","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 '0requests' is a one-character variant of the popular PyPI package 'requests'. On import of the top-level package, __init__.py enumerates os.environ and collects every variable whose name begins with SECRET, API, TOKEN, or KEY, then opens a TCP socket to a host/port taken from the TS_HOST and TS_PORT environment variables and sends the serialized dictionary of credential-shaped variables. The same import path spawns a python subprocess that connects to the same TS_HOST:TS_PORT, sends a 'SHELL' marker, and sleeps to keep the socket open, providing a remote-controlled shell channel on the host. Console output includes '0requests installed -- targeting requests' and a '[typosquat] exfiltrating' log line, confirming intent.\n\nDuring import, the code exfiltrates potentially sensitive env variables. In all analyzed versions the exfiltration target was a localhost, suggesting it was just a test.\n\n---\n\nCategory: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research \u0026 co, with clearly low-harm possibilities.\n\nCampaign: 2026-09-0requests\n\nReasons (based on the campaign):\n\n - exfiltration-env-variables\n\n - typosquatting","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 0requests (PyPI)","id":"MAL-2026-15859","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":"0requests","purl":"pkg:pypi/0requests","source":"MAL-2026-15859"}],"products":null,"published":"2026-09-03","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-2026-15859/"}
