T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a mass of external links, masquerading as a document about 'chemistry final exam answers'. One of these links, https://ttraff.cc/pify?keyword=chemistry+final+exam+answers, points to a known malicious redirector. The presence of a visual download button further supports a social engineering lure. The document body is heavily obfuscated and contains the malicious URL, indicating an attempt to trick the user into navigating to malicious content.
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
-
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=chemistry+final+exam+answers
