T1566.002 Spearphishing Attachment
T1204.002 User Execution: Malicious Link
The PDF contains a large number of embedded links, many of which point to a link farm designed to redirect users to potentially malicious sites. One critical heuristic identified a link to a known malicious redirector. The document body, while heavily obfuscated, contains text related to multiplication worksheets and a URL that appears to be a lure. The presence of numerous PDF links and a redirector link strongly suggests a phishing or malicious redirection attempt.
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.
-
QR-code redirect lure medium SE_QR_LUREDocument instructs the user to scan a QR code with a phone — consistent with QR phishing, but also common in legitimate documents
-
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.com/wix?keyword=3-digit+by+1-digit+multiplication+worksheets
