T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, many of which point to shopify.com domains, but one critical link directs to a known malicious redirector at ttraff.ru. The document body, though heavily obfuscated, contains text related to 'scrumstudy scrum master exam questions' and the malicious URL, suggesting a lure to trick users into clicking the link. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK confirms the presence of a malicious redirector, and PDF_SEO_LINK_FARM indicates a large number of outbound links, likely for SEO manipulation or to obscure the malicious destination.
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.
-
