T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains a mass external link farm, with many links pointing to Shopify and static.usrfiles.com domains, likely for SEO poisoning. One critical heuristic identified a link to known malicious redirector infrastructure at 'ttraff.cc'. The document body, though heavily obfuscated, contains a reference to 'All cast receiver pc' and the malicious URL. The heuristic 'SE_CLOUD_DOC_LURE' indicates the document impersonates a cloud file-sharing service to trick the user into clicking the malicious link.
Heuristics 4
-
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.
-
Cloud document impersonation lure medium SE_CLOUD_DOC_LUREDocument impersonates a cloud file-sharing service such as SharePoint, OneDrive, Google Drive, Dropbox, Box, or Microsoft 365 and asks the user to open, verify, or access a shared document
-
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=all+cast+receiver+pc
