T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF contains a mass of external links, many hosted on shopify.com, designed to appear as legitimate documents but likely serving as a link farm. One prominent link, 'https://ttraff.ru/pify?keyword=medexpress+virtual+job+tryout+answers', is flagged as a malicious redirector. The document body, though heavily obfuscated, contains this malicious URL and references a 'medexpress virtual job tryout', suggesting a lure to trick users into clicking the malicious link. No scripts were extracted, but the PDF structure and link analysis strongly indicate a phishing or malware distribution attempt.
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.
-
