MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a PDF document that contains an embedded URL pointing to a suspicious domain. Heuristics indicate the presence of external URIs and a high likelihood of malicious content, with ClamAV specifically identifying it as a phishing trojan. The document body, though heavily obfuscated, suggests a lure related to 'Milk on 21 day fix', likely a deceptive tactic to encourage clicks on the malicious link.
