T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a mass of external links, many of which are to benign Shopify URLs, but one critical link points to a known malicious redirector. The document body, though heavily obfuscated, contains text related to 'company letterhead template free' and the malicious URL, suggesting a lure. The ML classifier also strongly flagged this PDF as malicious. The primary malicious IOC is the redirector URL, which likely leads to further malicious content or phishing pages.
