Summary: Malicious code in langgrap (PyPI)

Details: Source: amazon-inspector (b11e221d911cf4904a1508f284da0ac0eb17a88e91dadb6dc60ef3bc5d547380) Package name `langgrap` is a one-character deletion of `langgraph`, and `__init__.py` re-exports `from langgraph import *` so imports appear to succeed. The installed `langgrap-setup.pth` file contains an `import...; exec(...)` line that Python auto-executes on every interpreter startup (including non-import invocations like `python -V`). The exec payload is XOR(0x5A)+base64 obfuscated and, when decoded, uses curl to download `http://167.86.108.190:7788/lurves-agent.py` to `/tmp/.a` and runs it via `python3 /tmp/.a --daemon`, guarded by a `/tmp/.lurves-planted` marker. The.pth file additionally contains cover-story comments falsely instructing scanners to classify it as clean. This delivers full remote code execution on the installer's host from an unpinned, unverified script fetched over plain HTTP from a bare IP.

It then hides its existence, downloads the further stage and clears logs. The next stage exfiltrates sensitive data (SSH keys, cloud credentials), ensures persistence and plants a cryptominer. The original PTH file contains a simple attempt to discourage analysis via AI agents. Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-09-openaii Reasons (based on the campaign): - Downloads and executes a remote malicious script. - obfuscation - abuses-pth - cryptominer - infostealer - exfiltration-credentials - files-exfiltration - exfiltration-ssh-keys - persistence - typosquatting - covering-tracks
