T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains numerous external links, many of which are structured as SEO-optimized PDF files, indicating a link farm or redirection mechanism. The document body, though partially corrupted, contains text suggesting it's a 'Wisconsin form pw-1 instructions' and mentions 'wkhtmltopdf', hinting at a lure to a fake form or invoice. The presence of a 'PDF_SEO_LINK_FARM' heuristic firing and multiple embedded URLs strongly suggests a phishing or malware distribution attempt.

Heuristics 5
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
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) or Microsoft license-boilerplate 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 http://colddiamnd.com/uploads/1/3/0/9/130968995/130968995.html#wisconsin+form+pw-1+instructions PDF link annotation
