MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF file contains embedded JavaScript and RichMedia (Flash) content, as indicated by the PDF_JAVASCRIPT, PDF_JS, and PDF_RICHMEDIA heuristics. ClamAV detection (Pdf.Exploit.Agent-35955) confirms its malicious nature. The embedded artifact 'bdHlYfidjI.swf' is likely the exploit payload. The overall attack pattern suggests a drive-by download or spearphishing attachment leading to exploitation of a PDF vulnerability to execute the embedded Flash content.

Heuristics 7

ClamAV: Pdf.Exploit.Agent-35955 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-35955
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
RichMedia (Flash) high PDF_RICHMEDIA

PDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
