MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a lure related to 'work word problems with solutions and answers pdf' to entice users to click on embedded links. One primary link directs to a known malicious redirector, ttraff.com. Additionally, the document hosts a large farm of SEO-optimized PDF links, many hosted on cdn.shopify.com, which is a common tactic for distributing malicious content or for SEO manipulation. The presence of a malicious redirector and the link farm indicate a phishing or content-luring attack pattern.
