MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains multiple embedded URLs, one of which is `https://trafficel.ru/aws?utm_term=aruba+2530-+8g+switch+manual`, suggesting a phishing attempt to lure users to a malicious site. The heuristic `PDF_SEO_DISPOSABLE_LINK_FARM` indicates a pattern of using disposable hosting for multiple links, further supporting the phishing lure. ClamAV detection as `Pdf.Phishing.Trojan-d2568dad23a94d95-d2568dad23a94d95-10044375-0` confirms its malicious nature.

  • 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.
