MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a heuristic indicating it's an SEO redirector link, disguised as a free download lure. This link points to 'https://trafficel.ru/aws?utm_term=15+meter+beep+test+free', which is likely used to deliver a malicious payload or conduct phishing. No scripts were extracted, but the presence of a redirector strongly suggests a malicious intent to lure users to a compromised site.

Heuristics 3

  • Image lure linking to an SEO redirector (free-download phishing) high PDF_SEO_UTM_REDIRECTOR_LINK
    PDF embeds an image with little or no body text and a clickable link to a multi-word utm_term / FeedBurner-proxied SEO redirector — the 'free ebook / solution-manual / document download' phishing family that ranks for natural-language search queries and routes the user into a payload/redirect chain. The PDF carries no exploit; the risk is the linked destination. Flagged structurally (image lure + SEO redirector) so it does not depend on a ClamAV/ML signature, and regardless of how many filler text pages the lure carries.
