MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF document contains a link farm and presents itself as a guide for applying for a 'Fastag', which is a common lure for phishing or scam operations. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of external links, and 'SE_CALLBACK_LURE' suggests a callback phishing or tech-support scam pattern. The ClamAV detection further confirms its malicious nature. No scripts were extracted from this sample.

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
