MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample is a malicious Word document containing VBA macros, specifically a Document_Open macro, which is a common technique for executing malicious code upon opening the document. The document body attempts to appear as a legitimate regional call for projects, likely to trick the user into enabling macros. The presence of the 'macros.bas' file and the embedded URL 'http://www.ragazzidelfiume.it' are key indicators. The ClamAV detection 'Doc.Trojan.Proverb-1' further confirms its malicious nature.

Heuristics 5

ClamAV: Doc.Trojan.Proverb-1 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Trojan.Proverb-1
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open macro
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 http://www.ragazzidelfiume.it
