Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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-2026-17927/ (Markdown: https://insights.sbomify.com/MAL-2026-17927/index.md)","id":"MAL-2026-17927","markdown":"https://insights.sbomify.com/MAL-2026-17927/index.md","name":"MAL-2026-17927","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"fabtoolkit executes a payload (embedded as a CHILD string run via `subprocess.run([sys.executable,'-I','-c',CHILD],...)`) that fetches a JSON config from https://transfer.archivete.am/H2Uxm/fabdeploycheck-config.json with TLS verification disabled (`ssl._create_unverified_context()`) and dispatches on config-supplied `kind` values: `file` reads arbitrary filesystem paths, `run` executes attacker-supplied argv via subprocess, `http` issues attacker-chosen requests with Bearer tokens chained from previously-read files, `tcp` probes ports, and `revsh` forks a daemon that polls `base+'/'+ident+'-cmd.txt'` and pipes the returned bytes into `/bin/sh -c`, PUTting stdout/stderr back to the same host. Collected file contents, command output, HTTP responses, and probe results are packed into an in-memory zip and PUT to transfer.archivete.am under an attacker-chosen report name. Before daemonizing, the payload walks `/proc/*/cmdline` and SIGKILLs processes whose cmdlines contain `FABDRV3`, `fabdrv2`, or `connection ready`, enforcing single-instance persistence and clearing prior variants. The entry points `python -m fabtoolkit` and any import path reaching `selftest()`/`check()` trigger the payload. The destination is an anonymous public file-transfer host; config-controlled file reads enable harvesting of credentials such as `~/.aws/credentials` and `~/.ssh/*` along with cloud metadata via the `http` kind. The package has no legitimate functionality matching its naming.","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 fabtoolkit (PyPI)","id":"MAL-2026-17927","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":"fabtoolkit","purl":"pkg:pypi/fabtoolkit","source":"MAL-2026-17927"}],"products":null,"published":"2026-10-19","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-2026-17927/"}
