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

The PDF file contains a lure related to a search query, designed to trick users into clicking on a malicious URL. The embedded URL, 'https://maypoin.ru/aws?utm_term=which+of+the+following+is+cycled+through+time', is flagged as a redirector for phishing. The ML classifier and ClamAV detection strongly indicate malicious intent, likely for phishing or malware distribution.

  • 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.
