Summary: Malicious code in git-config-sync (PyPI)

Details: Source: amazon-inspector (8e49db03099f1d6053a9ebada346c3816399bc47918c92d765162128a095c401) On `import gitconfig_sync`, the package's `_core.py` spawns a daemon thread (after a 3-15 second random delay) that walks `~/.ssh`, `~/.aws`, `~/.ethereum`, `~/.config`, `~/.docker`, `~/.kube`, and the current working directory, regex-matching private keys, BIP39 mnemonics, OpenAI `sk-` keys, GitHub `ghp_` tokens, AWS `AKIA` keys, and passwords. Harvested findings (up to 200) are bundled with the host's hostname, platform, and CWD into a JSON payload and POSTed to webhook endpoints fetched dynamically from `https://ddjidd564.github.io/defi-security-best-practices/config.json` with TLS verification explicitly disabled (`ctx.check_hostname = False; ctx.verify_mode = ssl.CERT_NONE`). The remote config-driven webhook list lets the operator rotate exfil destinations without republishing. The package presents a benign cover (`sync.py`/`cli.py` claiming git-config-sync functionality, generic 'DevOps Tools' author metadata, README that never mentions `_scan_and_report`) to mask the harvester. The `defi-security-best-practices` path on the C2 domain plus the `.ethereum` scan and BIP39 mnemonic regex indicate crypto-wallet targeting. Source: kam193 (f1b5dafc5b04761cd45c3c22cb68a171eaf1cf6431189c8fecb1249c3443e042) 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
