T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains a link farm and a direct link to a known malicious redirector, ttraff.ru. The document body, though heavily obfuscated, contains text related to 'diagnostic tests for hiv pdf' and the malicious URL itself, suggesting a lure to a phishing or malware distribution site. The presence of numerous PDF links, many hosted on Shopify, indicates an attempt to create a link farm for SEO poisoning or to obscure the final malicious destination.
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.
-
Urgency / deadline lure low SE_URGENCY_LUREDocument contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
-
Embedded URL info EMBEDDED_URLOne 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.URL https://ttraff.ru/pify?keyword=diagnostic+tests+for+hiv+pdf
