MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF contains embedded JavaScript and a critical heuristic firing indicates a malicious redirector link. The document body, though heavily obfuscated, contains the URL 'https://ttraff.ru/pify?keyword=bradycardia+guidelines+pdf' which is flagged as malicious. This suggests the document is designed to lure users into clicking the malicious link, likely to download a second-stage payload.

Heuristics 4

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 JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Urgency / deadline lure low SE_URGENCY_LURE

Document contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
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.
URL https://ttraff.ru/pify?keyword=bradycardia+guidelines+pdf
