MITRE ATT&CK

T1204.002 Malicious File T1059.005 Visual Basic T1059.003 Windows Command Shell

The sample contains VBA macros, including an AutoOpen macro, which is a common delivery mechanism for malware. Heuristics indicate the use of WinExec and cmd.exe, suggesting the execution of arbitrary commands. The presence of CVE-2012-0158 points to exploitation of a known vulnerability in MSCOMCTL.ListView. The VBA p-code indicates auto-execution with shell tokens, likely to download and run a second-stage payload.
