T1566.002 Spearphishing Attachment T1204.002 Malicious File

This PDF file contains a large number of external links, a technique often used for SEO spam or to redirect users to malicious sites. The ML classifier strongly indicated maliciousness. The primary lure appears to be related to 'Indian punjabi comedy movies free mp4', which is likely a deceptive tactic to mask the true malicious intent of directing users to the numerous external URLs.
