T1059.001 PowerShell
The PDF file contains a large number of embedded links, many of which point to a link farm hosted on Shopify. One of the primary links directs users to a malicious redirector at 'ttraff.cc', which is likely part of a phishing or malware distribution scheme. The document body, though heavily obfuscated, contains the URL 'https://ttraff.cc/pify?keyword=antibiotic+resistance+pdf+articles', suggesting a lure related to academic articles. The heuristic firings confirm the presence of malicious redirector links and a link farm, indicating a coordinated effort to drive traffic to malicious sites.
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.cc/pify?keyword=antibiotic+resistance+pdf+articles
