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","affected":[{"package":{"name":"webreader","ecosystem":"PyPI"},"versions":["2.3.8"]}],"references":[{"type":"WEB","url":"https://bad-packages.kam193.eu/pypi/package/webreader"}],"database_specific":{"iocs":{"domains":["frjmzbjbhwvtdnsuodmu.supabase.co"],"urls":["https://api.npoint.io/40e32d283a9d97e59252/a"]},"malicious-packages-origins":[{"id":"pypi/2026-10-webreader/webreader","import_time":"2026-10-10T11:40:44.044652644Z","modified_time":"2026-10-10T11:07:02.763324Z","sha256":"165632b7385ab993b6a8aa74c76ff55cc1ef55748c67b5dfabca284bc8ced087","source":"kam193","versions":["2.3.8"]},{"id":"pypi/2026-10-webreader/webreader","import_time":"2026-10-20T14:18:32.002920669Z","modified_time":"2026-10-10T11:07:02.763324Z","sha256":"9a6899ef4008e014cbfd019b0110720f1968698d9ecfdf603f7e54e864bfdfdd","source":"kam193","versions":["2.3.8"]}]},"credits":[{"name":"Kamil Mańkowski (kam193)","contact":["https://github.com/kam193","https://bad-packages.kam193.eu/"],"type":"REPORTER"}]}
