MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains a large number of embedded links, many of which point to a link farm designed to redirect users. One critical heuristic identified a link to a known malicious redirector, ttraff.cc, which is used to obscure the final destination. The document body, though heavily obfuscated, contains references to the redirector URL and benign-sounding topics like 'Base64 image to pdf java', likely a lure. The presence of numerous Shopify-hosted PDFs suggests an attempt to blend in with legitimate content while distributing malicious links.
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=base64+image+to+pdf+java
