MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. This suggests a phishing or SEO poisoning attack, aiming to redirect users to potentially malicious content. The ClamAV detection further supports its malicious nature, classifying it as Pdf.Phishing.TtraffRobotInstall. No scripts were extracted from this sample, and the document body was heavily obfuscated, limiting further analysis of the specific lure.
