MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
This PDF document contains a large number of embedded links, many of which point to a link farm hosted on Shopify. One of the primary links, 'https://ttraff.ru/pify?keyword=gmat+verbal+pdf', is identified as a malicious redirector. The document body, though heavily obfuscated, contains references to 'gmat verbal pdf' and the tool 'wkhtmltopdf', suggesting a lure to trick users into downloading malicious content disguised as study material. The presence of a visual download button further supports this phishing pretext.
Heuristics 4
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF 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.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
