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.

Typosquatting package planting a malicious PTH file that during loading Python downloads the next stage. 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.
