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\n\n## Affected packages\n\n- `resion`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"abyssal","depthScore":70,"depthScoreParts":{"impact":52.3,"likelihood":0,"exploitation":18,"ransomware":0},"changes":[]}
