MITRE ATT&CK

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

The sample contains a VBA macro with an AutoOpen function that utilizes the Shell() command. This indicates the macro is designed to execute arbitrary commands upon opening the document. The embedded URL 'http://tan.mundoholistico.co/lexisnexis/search/bgreport.php' is likely used to download and execute a secondary payload. The presence of the Shell() call and the AutoOpen macro strongly suggests a malicious intent to compromise the user's system.

Heuristics 6

Shell() call in VBA critical OLE_VBA_SHELL

Shell() call in VBA
AutoOpen macro high OLE_VBA_AUTOOPEN

AutoOpen macro
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
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 — context-specific rules above attribute URLs they actually evaluated; this rule lists URLs that were present in the bytes but were not otherwise tied to a specific finding.

URL http://tan.mundoholistico.co/lexisnexis/search/bgreport.php
