T1566.001 Spearphishing Attachment
The PDF document contains a large number of external links, many of which point to PDF files hosted on `grazzio.ru`. This suggests a link farm or SEO manipulation tactic. The presence of a malicious ML classification and embedded URLs indicates an intent to redirect users to potentially harmful content or download further payloads. No scripts were extracted, but the structure and embedded URLs are highly suspicious.
