T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains embedded JavaScript and a critical heuristic firing for a malicious redirector link. The document body, though heavily corrupted, contains text suggesting it is a lure for 'database development for dummies'. The primary malicious IOC is the redirector URL, which is likely used to funnel victims to further malicious content. The PDF also contains a large number of external links, many of which point to Shopify domains, suggesting a link farm or SEO poisoning tactic.
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/wix?keyword=database+development+for+dummies
