MITRE ATT&CK

T1059.007 JavaScript T1566.001 Spearphishing Attachment

The PDF was flagged by multiple heuristics, including a critical ClamAV detection for 'Unix.Trojan.PhpBackdoor-9354530-2' and a high severity heuristic for an 'eval() call'. The ML classifier also strongly indicated maliciousness. While the document body is unreadable and no scripts were explicitly extracted, the presence of an embedded URL and the nature of the heuristics suggest this PDF is designed to execute malicious code, likely a backdoor, upon opening.
