MITRE ATT&CK

T1059.005 Visual Basic T1105 Ingress Tool Transfer

The sample contains VBA macros that utilize CreateObject and CallByName functions, indicative of malicious intent. The script attempts to establish communication with the URL 'https://saervilohim.top/ecm/ibm/1633157120/feedback' using 'MSXML2.ServerXMLHTTP' to download and execute a second-stage payload. The presence of the 'macros.bas' file further supports the macro-based execution. The exact functionality after the initial download is truncated, limiting full analysis.

Heuristics 5

CreateObject call high OLE_VBA_CREATEOBJ

CreateObject call
CallByName call high OLE_VBA_CALLBYNAME

CallByName call
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
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.
