T1566.001 Spearphishing Attachment

This PDF document is identified as malicious due to its structure and embedded link. It functions as a screenshot lure, presenting a seemingly static image that conceals a clickable link. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK specifically flags the embedded URL, https://cctraff.ru/aws?keyword=southern+strategy+nixon+apush, as pointing to known malicious redirector infrastructure. The ML classifier also indicated a high probability of maliciousness.

Heuristics 3

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE

PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 33 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
