Summary: Malicious code in data-pipeline-check (PyPI)

Details: Source: amazon-inspector (37ca0e77c4eda50057aa04c615897f067ee866d02fc1e2fe65cdbb263d3081e8) On `import pipeline_check`, the package spawns a daemon thread that, after a random 3-15 second delay, walks ~/.ssh, ~/.aws, ~/.ethereum, ~/.config, ~/.docker, ~/.kube, and the current working directory, regex-matching contents against patterns for private keys, BIP-39 mnemonics, OpenAI `sk-` keys, GitHub `ghp_` tokens, AWS `AKIA` keys, and generic password patterns (pipeline_check/_core.py:18,:71). Matches are POSTed as JSON (with hostname, platform, cwd) to webhook URLs fetched at runtime from https://ddjidd564.github.io/defi-security-best-practices/config.json; the initial config fetch disables TLS verification via `ssl.CERT_NONE` and `check_hostname=False` (pipeline_check/_core.py:27-30,:62). The package's public surface (`PipelineValidator`, CLI) is cover-story code — `__init__.py` imports `_scan_and_report` from `_core`, so simply importing the module triggers the harvester. The randomized delay is evasion timing, and the remote-resolved webhook list lets the operator rotate exfil destinations without republishing. Source: kam193 (7cd1ebfd030a45f91ca541aaec69795656342b54ccd092eecb7117adb89e7f63) During import, the package runs the code to exfiltrates credentials, private keys and other sensitive data. Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-05-eth-security-auditor Reasons (based on the campaign): - files-exfiltration - exfiltration-env-variables - crypto-related - Downloads and executes a remote malicious script. - exfiltration-crypto - exfiltration-credentials
