MITRE ATT&CK

T1204.002 Malicious File T1566.001 Spearphishing Attachment T1027 Obfuscated Files or Information

The sample is a PDF file that contains an embedded script payload, as indicated by the 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristic. ClamAV detections confirm this, identifying it as 'Pdf.Exploit.CVE_2010_0188-10'. This exploit targets a known vulnerability in PDF readers, likely to download and execute a second-stage payload. The embedded artifact 'embedded_file_obj0006.bin' is the likely payload carrier.

Heuristics 6

ClamAV: Pdf.Exploit.CVE_2010_0188-10 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.CVE_2010_0188-10
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.
Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD

PDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
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.
