If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-5756/ (Markdown: https://insights.sbomify.com/MAL-2026-5756/index.md)","id":"MAL-2026-5756","markdown":"https://insights.sbomify.com/MAL-2026-5756/index.md","name":"MAL-2026-5756","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On `pip install easyaillm`, setup.py runs `exec(base64.b64decode(...))` which decodes to code that fetches https://pastebin.com/raw/hEF5HaFc, treats the response body as a second URL, downloads that URL's bytes to `pkg_installer.exe`, and executes it via `os.system('cmd /c pkg_installer.exe')`. The attack stages are concealed behind a base64 blob and `exec()` indirection, while the package metadata advertises an unrelated LLM/Roblox API purpose as cover. The pastebin source is mutable and anonymous, allowing the operator to swap the second-stage URL and ultimately the executed binary at any time. Installing this package on Windows results in arbitrary attacker-controlled code execution on the installer's machine.\n\nDuring installation, the obfuscsted code attempts to download and start a malicious executable.
