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\n---\n\nCredit: OpenSSF ([source](https://github.com/ossf/malicious-packages/blob/1861f95ffacc04ed9d9c6049639098146030f14b/osv/malicious/pypi/webreader/MAL-2026-17757.json","public_affected_ranges":["= 2.3.8"]}],"null_published_at":"2026-10-31T22:13:44.206Z","source_updated_at":"2026-10-20T15:31:09.000Z","source_disclosed_at":"2026-10-10T12:30:31.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T22:06:01.047Z"}],"next_cursor":null,"snapshot_revision":"42594"}
