MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment
T1204.001 User Execution: Malicious Link
T1059.001 Command and Scripting Interpreter: PowerShell
The PDF document contains numerous embedded links, including one pointing to a known malicious redirector. The document body text, though obfuscated, contains keywords related to educational material and includes the malicious URL. The presence of a 'download button' heuristic further supports the lure. The primary intent appears to be redirecting the user to malicious infrastructure via a deceptive 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.
-
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/wb?keyword=11th%20class%20science%20book%202019%20pdf
