MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell T1204.002 Malicious File

The sample is a malicious Office document containing VBA macros, specifically an AutoOpen macro, which is a common technique for initial execution. The macros likely download and execute a second-stage payload from the unknown URL 'https://lakammes.xyz/hdcdrive4.exe'. The presence of CreateProcess API calls further supports the execution of external code.

Heuristics 6

Reference to CreateProcess API high SC_STR_CREATEPROCESS

Reference to CreateProcess API
AutoOpen macro high OLE_VBA_AUTOOPEN

AutoOpen macro
Suspicious extracted artifact high 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.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Environ() call (env variable access) low OLE_VBA_ENVIRON

Environ() call (env variable access)
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
