MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF document contains a large number of external links, many of which are numerically or generically named, suggesting a link farm for SEO manipulation or to host malicious content. One prominent link points to a page about 'Indian online visa application for afghanistan', indicating a potential phishing or scam lure. The document's structure and the presence of numerous unknown-reputation URLs suggest it is part of a campaign to redirect users to potentially harmful websites.
