MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The file is a PDF that contains an embedded URL pointing to a suspicious domain. Heuristics indicate it's a password-protected archive lure, suggesting the PDF itself is a decoy to trick the user into downloading a secondary payload. ClamAV detection confirms its malicious nature, specifically flagging it as phishing-related. The embedded URL is the primary indicator of the attack vector.
