A related dependency (pafex) 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. During analysis, the final remote payload was just a stub\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 - files-exfiltration\n\n\n - obfuscation\n\n\n - The malicious code is intentionally included in a dependency of the package\n\n\n - Downloads and executes a remote malicious script.\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 - rat\n\n\n - persistence\n\n\n - abuses-pth\n","modified":"2026-10-20T14:30:03.659288229Z","published":"2026-10-20T13:16:36Z","database_specific":{"iocs":{"urls":["https://api.npoint.io/40e32d283a9d97e59252/a","https://api.npoint.io/69f11497b6c48bb2b2c5/p"],"domains":["frjmzbjbhwvtdnsuodmu.supabase.co"]},"malicious-packages-origins":[{"sha256":"2e9e3ce373adb26e45616eec47d727e557f5a696737cb2fbcaa66fb7dc7b7c3e","source":"kam193","versions":["22.0.1"],"id":"pypi/2026-10-webreader/resion","import_time":"2026-10-20T14:18:32.002071088Z","modified_time":"2026-10-20T13:16:36.629288Z"}]},"references":[{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/resion"}],"affected":[{"package":{"name":"resion","ecosystem":"PyPI","purl":"pkg:pypi/resion"},"versions":["22.0.1"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/pypi/resion/MAL-2026-18095.json"}}],"schema_version":"1.9.0","credits":[{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"],"type":"REPORTER"}]}
