MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF file was detected as malicious by multiple engines, including ClamAV and an ML classifier. It contains a large number of embedded links pointing to external PDF files hosted on the domain 'calistazz.myhome.cx'. This suggests a link farm or SEO poisoning tactic, likely intended to drive traffic to malicious content or potentially distribute further malware. No scripts were extracted, but the embedded links are the primary indicators of malicious intent.
