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

The PDF file contains a link farm heuristic, indicating a large number of external links. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall' further supports a phishing or malware distribution intent. The document body, though heavily obfuscated, contains text related to 'Indonesia visa form' and includes multiple URLs pointing to PDF files, suggesting a lure to download malicious content. No scripts were extracted from this sample.

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
