MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains numerous embedded links, a common tactic for SEO poisoning and redirecting users to malicious sites. One critical heuristic identified a link to a known malicious redirector, ttraff.cc, which is disguised as a chemistry textbook PDF. The document body, though heavily obfuscated, contains the same URL and references to chemistry textbooks, reinforcing the lure. The presence of multiple shopify.com links, while marked as benign, are part of a larger link farm strategy. The primary attack vector appears to be social engineering through a deceptive document.
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=peter+atkins+principios+de+quimica+pdf
