A related dependency (pafer) contains code to load the pickle. During unpickling, malicious code embeded in the pickle file is automatically executed. It then establishes persistence via a PTH file and downloads the next stage payload. It finally acts like a RAT, allowing remote exfiltration and code execution.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-10-webreader\n\n\nReasons (based on the campaign):\n\n\n - rat\n\n\n - Downloads and executes a remote malicious script.\n\n\n - obfuscation\n\n\n - The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.\n\n\n - abuses-pth\n\n\n - persistence\n\n\n - The malicious code is intentionally included in a dependency of the package\n\n\n - files-exfiltration\n","modified":"2026-10-10T11:45:03.481597357Z","published":"2026-10-10T11:11:35Z","database_specific":{"iocs":{"domains":["frjmzbjbhwvtdnsuodmu.supabase.co"],"urls":["https://api.npoint.io/40e32d283a9d97e59252/a"]},"malicious-packages-origins":[{"id":"pypi/2026-10-webreader/pafer","import_time":"2026-10-10T11:40:44.044102873Z","modified_time":"2026-10-10T11:11:35.029137Z","sha256":"a74b7c5b356a87fe0262954cbedbcc432497ab25edaccbade0ce9ce04b16a8c9","source":"kam193","versions":["0.9.7","0.9.8"]}]},"references":[{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/pafer"}],"affected":[{"package":{"name":"pafer","ecosystem":"PyPI","purl":"pkg:pypi/pafer"},"versions":["0.9.7","0.9.8"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/pypi/pafer/MAL-2026-17756.json"}}],"schema_version":"1.9.0","credits":[{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"],"type":"REPORTER"}]}
