T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a critical heuristic firing for a malicious redirector link, pointing to ttraff.com. This URL is presented within the document body, disguised as a search query for 'Frozen 2 all is found piano sheet music pdf'. The file also exhibits characteristics of a link farm, with numerous external links, many of which are benign Shopify URLs, likely used to mask the malicious redirector. The ML classifier strongly indicates maliciousness.
