T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF is identified as an image-only lure, typical for phishing campaigns. It contains a critical PDF_MALICIOUS_REDIRECTOR_LINK heuristic firing, pointing to 'https://ttraff.cc/wix?keyword=skylark+english+grammar+book+5+pdf'. This URL is likely used to redirect the user to a malicious site. The PDF also contains a PDF_SEO_LINK_FARM heuristic, indicating it's part of a larger network of linked PDFs, further suggesting a malicious intent to distribute content or lure users.
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.
-
Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LUREPDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 34 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
-
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/wix?keyword=skylark+english+grammar+book+5+pdf
