T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a heuristic indicating it's a malicious redirector link, pointing to `ttraff.com`. The document body, though heavily obfuscated, contains this URL and appears to be a lure for IELTS writing examples. The file also exhibits characteristics of a link farm, with numerous embedded URLs, many of which point to `cdn.shopify.com` hosting PDF files. The primary malicious URL is `https://ttraff.com/pify?keyword=ielts+writing+task+1+example+answer`, which is likely used to redirect the user to a further malicious destination.
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.
-
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
-
