MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links, many of which are numerically or generically named, suggesting a link farm or SEO poisoning tactic. The primary heuristic firing indicates a mass of external PDF links, with the dominant host being macherieboutique.com. The document body, though partially corrupted, contains a URL related to 'flat tummy exercise for beginners', which is likely a lure to direct the user to malicious content hosted on the identified domains.
