MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains embedded JavaScript and a critical heuristic firing indicates a malicious redirector link to ttraff.com. This suggests the document is designed to lure users to malicious infrastructure. Additionally, the PDF exhibits characteristics of a link farm, with numerous embedded URLs pointing to external resources, likely to improve search engine ranking or distribute further malicious content. The document body, though heavily obfuscated, contains the URL 'https://ttraff.com/pify?keyword=bruchrechnen+aufgaben+pdf+6.+klasse', reinforcing the redirector finding.
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.
-
Embedded JS stream low PDF_JSPDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
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/pify?keyword=bruchrechnen+aufgaben+pdf+6.+klasse
