What to do now4 steps

This file is harmful. Don't run it, and remove it.

If you haven't run it

  1. Don't run this file. Delete it, then empty the Recycle Bin.

If you already ran it

  1. Disconnect the device from the internet, then run a full antivirus scan. Microsoft Defender Offline (Windows Security > Virus & threat protection > Scan options) also finds malware that hides while Windows runs.

  2. If you typed passwords on the device after running it, change them from another device you trust.

  3. If the scan keeps finding it, or the device still acts strangely, scan again with a second-opinion scanner from another company; if that doesn't fix it, back up your personal files and reinstall Windows.

If you already ran it, do these in order.

If you opened or installed it

Avoid banking and sign-ins on that device until it is clean. These free MalwareTips guides walk you through it.

The reasoning behind this verdict

Analyst conclusion

The combination of major consensus on the Draftor family, offensive MITRE techniques observed in sandbox, and the complete absence of code signing or established signer history outweighs the medium prevalence and lack of external-intel corroboration. The file is and shows no test-file or hacking tool labels that would alter the classification.

What the test run showed

What the file did on a test computer

Confirmed in the test run

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

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

  • Note: Read the user name of the test computer.

  • Note: Listed the programs running on the test computer.

  • Note: Deleted files or logs during the test run (installers often clean up after themselves).

  • Note: Read basic details of the test computer, such as its Windows version.

  • Note: Looked through folders on the test computer (most installers do this).

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

  • 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 recording keystrokes; no keylogging was confirmed.

  • Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.

  • Not confirmed: A sandbox rule tagged this run as setting up auto-start; no auto-start entry was recorded.

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 trojans work

A trojan pretends to be something useful or harmless so that you run it. Once open, it does its real job in the background, from stealing data to opening a back door or downloading more malware.

Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.
