T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF contains a heuristic firing for a malicious redirector link and a link farm. The document body, though heavily obfuscated, contains a URL that appears to be a lure for a job appointment letter. This URL, 'https://ttraff.cc/pify?keyword=job+appointment+letter+for+new+employee+pdf', redirects to potentially malicious content. The presence of numerous links, many pointing to Shopify domains with PDF files, suggests a link farm designed to attract search engine traffic and potentially distribute malware.
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=job+appointment+letter+for+new+employee+pdf
