MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.005 Visual Basic

The sample is a malicious Word document containing VBA macros. The Document_Open macro is triggered upon opening the document, which then constructs the URL "http://diuar5.ru/" and attempts to open a password-protected document named "help.doc" from that URL using the password "donttouchme". This indicates a likely attempt to deliver a second-stage payload or phish credentials.

  • 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.
