MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.club/wix?keyword=lincoln+movie+worksheet+answers'. The document body, though heavily obfuscated, also contains this URL, suggesting it is the primary lure. The presence of multiple embedded URLs further supports the malicious intent of redirecting users to potentially harmful content. No scripts were extracted from this sample.

Heuristics 2

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
