T1204.002 Malicious Link
T1059.001 PowerShell
The PDF contains a malicious redirector link pointing to 'https://ttraff.com/pify?keyword=winzip+free+download+full+version', which is designed to lure users into downloading potentially malicious software. The document also includes a large number of links to PDFs hosted on Shopify, likely for SEO manipulation to improve search engine ranking for malicious download lures. The presence of a 'password-protected archive handoff' heuristic suggests that the user is expected to download an archive and is provided with instructions to decrypt it, further indicating a malicious workflow.
Heuristics 5
-
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.
-
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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.com/pify?keyword=winzip+free+download+full+version
