The reasoning behind this verdict

Analyst conclusion

Opening this spreadsheet caused Excel to launch mshta, obfuscated PowerShell, WScript, and a downloaded executable. Twenty-three of the 62 antivirus engines that checked it flagged it, while the completed sandbox run recorded exploit and credential-targeting activity consistent with an UrcBadur-linked Office downloader.

Where this verdict could be wrong3 caveats
  • Six major antivirus engines did not flag the file, so antivirus agreement is substantial but not universal.
  • The reputation check found no cached malicious or suspicious result for any of the 18 observed hosts; host reputation can change and does not negate the recorded download chain.
  • The ten dropped files have no saved verdicts, so they provide no file it created confirmation.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

What the test run showed

What the file did on a test computer

Confirmed in the test run

  • High concern: Searched files where passwords and keys are stored.

  • High concern: Opened a browser or password-manager store that holds saved logins.

  • Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).

  • Moderate concern: Ran commands or a script on the test computer.

  • Moderate concern: Downloaded a file during the test run.

  • Moderate concern: Checked whether it was running on a test computer.

  • Moderate concern: Hid files or windows on the test computer.

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as password-store access, but nothing touched the Windows password store.

  • Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.

  • Not confirmed: A sandbox rule tagged this run as weakening security settings; no setting change was recorded.

  • Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.

This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

Threat context

How downloaders work

This file is a delivery vehicle. On its own it can look small and harmless, but its job is to fetch and install the real payload, often a password stealer, ransomware or a bot, from a server the attacker controls.

Bottom line:Because the dangerous part arrives later, early scans can look cleaner than the threat really is.

Delete it, then empty the Recycle Bin or Trash. 23 of the 62 antivirus engines that checked it flag it, some as UrcBadur. Antivirus engines classify it as a downloader whose job is to fetch more malware onto the device. If you've already opened it, see the steps below.
What is this Excel spreadsheet?
This Excel spreadsheet is about 388.1 kB. Its original file name is hidden on this page for privacy, so we identify it by its SHA-256 fingerprint. VirusTotal first saw it on Oct 14, 2026.
How many antivirus engines detected this Excel spreadsheet?
23 of the 62 antivirus engines that checked it flag this Excel spreadsheet, including Kaspersky and ESET. We weigh which engines flagged it and what else the scan found, not just the count. A sandbox test run also rated its behaviour as malicious.
I already downloaded and opened this Excel spreadsheet — what should I do?
1) Delete it, then empty the Recycle Bin or Trash. 2) Run a full scan with your antivirus. 3) If it asked you to enable editing or macros, or a page it opened asked for a password or card details, change that password from another device and call your bank if you paid.
