T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a large number of external links, indicative of a link farm or phishing campaign. The 'SE_CALLBACK_LURE' heuristic suggests the document is designed to trick users into calling a fraudulent support number. The presence of numerous PDF links, including one pointing to 'golowaki.ru', reinforces the malicious intent to redirect users to potentially harmful sites.

Callback phishing phone lure medium SE_CALLBACK_LUREDocument asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) documents that carry no urgency or charge/dispute escalation.

External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne 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://golowaki.ru/123?utm_term=att+uverse+remote+s10-+s3+manual
