T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of embedded links, many of which point to external resources. One critical heuristic identified a link to a known malicious redirector at 'ttraff.ru'. The document body, though heavily obfuscated, contains text related to 'vacunas en mujeres embarazadas pdf' and the URL 'https://ttraff.ru/wb?keyword=vacunas%20en%20mujeres%20embarazadas%20pdf', suggesting a lure to a malicious site disguised as a document download. The presence of numerous Shopify links, some marked as benign, indicates an attempt to blend malicious links with legitimate ones.
Heuristics 3
-
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.
-
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/wb?keyword=vacunas%20en%20mujeres%20embarazadas%20pdf
