MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'ttraff.com'. The document body, though heavily obfuscated, contains a reference to 'grammar checker free for iphone' and the malicious URL. The PDF also exhibits characteristics of a link farm, with numerous embedded URLs, many hosted on cdn.shopify.com, likely to improve search engine ranking and distribute the malicious payload.
