MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded links to other PDF files, a technique often used for SEO spam or to direct users to malicious content. The heuristic 'SE_CALLBACK_LURE' suggests a phishing or tech-support scam context, further supported by the presence of URLs in the document body. ClamAV detection confirms this as malicious, specifically identifying it as 'Pdf.Phishing.TtraffRobotInstall-7605656-0'. No scripts were extracted from this sample.

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
