Don't run this file

If you already ran it, follow the steps below.

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. From another device you trust, change the passwords of your important accounts (email and banking first) and turn on two-step verification.

  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

The reasoning behind this verdict

Analyst conclusion

The unsigned executable drew 47 detections from 75 engines, including nine major detections. Microsoft and ESET identified confirmed keygen or patcher functionality, while several other engines reported Mint stealer or trojan traits; avoid running it and remove it from the system.

Where this verdict could be wrong4 caveats
  • No sandbox returned a malicious verdict and no offensive techniques were mapped; the single completed sandbox did not independently assign a malicious verdict.
  • No community YARA rule matched, the hash is not in the known-software reference database, and the hash is not listed in the MalwareBazaar malware database, although external-intelligence coverage can miss threats.
  • prevalence shows 526 unique sources and 623 submissions since 2021, so this is established rather than newly observed.
  • Major antivirus engines do not agree on one malware family; labels differ among patcher, keygen, generic trojan, unwanted program, and Mint stealer.

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

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

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

  • Note: Checked which security software was installed on the test computer.

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

  • 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 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 password stealers work

A password stealer runs quietly in the background and copies your private data, such as saved passwords, browser cookies, autofill details and crypto wallets, then sends it to criminals. You usually won't notice anything.

Bottom line:Stolen logins are used to break into your accounts or sold in bulk, so change passwords from another device.
