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

The PDF file was detected as malicious by ClamAV and contains a critical heuristic firing for a malicious redirector link. The embedded URL, http://botcraftman.ru/..., is the primary indicator of malicious intent, likely serving as a lure to a phishing or malware distribution site. No scripts were extracted, but the presence of the malicious URL strongly suggests a phishing or social engineering attack.
