T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a lure for an answer key to a math assignment, which is a common tactic for social engineering. It embeds numerous links, with one critical heuristic firing indicating a link to known malicious redirector infrastructure at 'https://ttraff.ru/pify?keyword=answer+key+for+math+8'. Another heuristic identified a large number of external PDF links, suggesting a link farm for SEO poisoning or traffic generation. The presence of a remote-support tool lure further indicates a malicious intent to potentially gain unauthorized access or deliver further payloads.
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.
-
Remote-support tool lure high SE_REMOTE_SUPPORT_LUREDocument instructs the user to install, open, or connect with a remote-support tool such as AnyDesk, TeamViewer, Quick Assist, or ScreenConnect — high-risk in an unsolicited 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.ru/pify?keyword=answer+key+for+math+8
