MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, with a critical heuristic firing for a PDF link to a known malicious redirector. The document body, though partially corrupted, contains text suggesting it is related to 'Hedwig's theme sheet music pdf', which is likely a lure. The primary malicious URL identified is https://ttraff.com/wix?keyword=hedwig%2527+s+theme+sheet+music+pdf, which is used to redirect the user. The file also contains a link farm of 30 external PDF links, many pointing to static.usrfiles.com, which is flagged as a potential SEO link farm.
Heuristics 3
-
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.
