MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file was detected by ClamAV as 'Pdf.Phishing.Trojan'. Static analysis revealed multiple external URIs embedded within the PDF, some of which are hosted on domains that appear to be link farms or disposable hosting. The document body is heavily obfuscated and unreadable, but the presence of external links and the ClamAV detection strongly suggest a phishing or malware distribution attempt. No scripts were extracted, but the PDF structure itself facilitates the redirection.

  • Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARM
    Small PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.
