MITRE ATT&CK
T1059.005 Visual Basic for Applications
T1059.003 Windows Command Shell
The document contains a geography quiz, a common lure for users to enable macros. The presence of VBA macros and a critical heuristic firing for Shell() calls indicates that the macros are designed to execute arbitrary commands. ClamAV detections 'Doc.Trojan.Ded-3' and 'Doc.Trojan.Ded-1' further confirm the malicious nature of the file and its extracted components. The primary intent appears to be the execution of a second-stage payload via the Shell() function.
Heuristics 5
-
Shell() call in VBA critical OLE_VBA_SHELLShell() call in VBA
-
ClamAV: Doc.Trojan.Ded-3 critical CLAMAV_DETECTIONClamAV detected this file as malware: Doc.Trojan.Ded-3
-
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAVClamAV 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.
-
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGEOne 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.
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
