MITRE ATT&CK

T1566.002 Phishing: Spearphishing Attachment T1204.002 Malicious File: Malicious Link

The PDF document contains a large number of embedded links, many of which point to a redirector infrastructure identified as malicious. The primary malicious URL is https://ttraff.ru/wb?keyword=leed%20ap%20bd+c%20exam%20preparation%20guide%20. This behavior is consistent with a link farm designed to drive traffic to potentially harmful sites, likely for SEO manipulation or to host further malicious content. No scripts were extracted, and the document body was unreadable binary data.

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.
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

Small 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.
