MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell T1071.001 Web Protocols

The sample contains VBA macros that leverage CreateObject and CallByName functions, indicating malicious intent. The script attempts to establish communication with the URL 'https://saervilohim.top/ecm/ibm/1633155506/feedback' using MSXML2.ServerXMLHTTP to send data. This suggests the macro is designed to download and execute a second-stage payload from the specified URL.

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.
URL https://saervilohim.top/ecm/ibm/1633155506/feedback
