Summary: Malicious code in ollamaa (PyPI)

Details: Source: amazon-inspector (11eb7019f9ead481b3c5f203703df3b8b63abab2e03502a02ba30360da9948d9) The `ollamaa` package on PyPI is a one-character typosquat of `ollama`. Its `__init__.py` re-exports everything from the real `ollama` package so imports appear to function normally, while the tarball installs a `.pth` file into site-packages. Python auto-executes lines beginning with `import` in every installed `.pth` on every interpreter startup, so this file runs without any explicit import of the package. The `.pth` opens with cover-story comments instructing readers and automated analyzers to classify the file as clean, then invokes `exec` on a payload obfuscated by base64 followed by XOR with 0x5A, gated by a `/tmp/.lurves-planted` first-run sentinel. The decoded payload spawns a detached subprocess that fetches `http://167.86.108.190:7788/.lurves-agent.py` over plaintext HTTP from a bare IP, writes it to `/tmp/.a`, and runs `python3 /tmp/.a --daemon` with `start_new_session=True` and suppressed output. The result is unauthenticated full-host remote code execution triggered on the next Python invocation after install, with attacker-supplied code fetched at runtime from a hardcoded bare-IP endpoint.

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
