T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'https://ttraff.ru/wb?keyword=cost%20accounting%20past%20questions%20and%20answers%20pdf'. Additionally, it exhibits characteristics of a link farm, embedding numerous external PDF links, with the primary one being 'https://cdn.shopify.com/s/files/1/0437/4442/8181/files/kovotegibilipixuwogixivem.pdf'. The document body, though heavily corrupted, contains text related to cost accounting and the malicious URL, suggesting a lure to disguise the malicious redirection.
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=cost%20accounting%20past%20questions%20and%20answers%20pdf
