Verdict Malicious

Analyzed , 2 days ago

Is stable-diffusion-wormgpt.zip safe? No, we rate this exact file malicious.

This archive masquerades as a Stable Diffusion package but 42 of the 64 antivirus engines that checked it, including eleven major ones, name a lock-screen trojan, and the sandbox recorded script execution plus an autostart entry.

Strong evidence · Two or more major antivirus engines agree.

Don't open or extract this archive

Delete the archive without extracting or running it. If it has already been unpacked or executed, run a full antivirus scan and remove the SystemLocker autostart entry under the current user's Run key, keeping your protection enabled throughout.

What to do now3 steps

This ZIP archive is harmful. Don't open or extract it, and delete it.

If you haven't opened or extracted it

  1. Don't open or extract this archive. Delete the archive and any files you extracted from it, then empty the Recycle Bin or Trash.

If you already opened or extracted it

  1. If you already extracted it, delete the extracted files too and run a full antivirus scan.

  2. If a page it opened asked for a password or card details and you entered them, change that password and call your bank.

Why we think so

6 points against it and 3 in its favour, checked against the scan evidence.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

Forty-two of the 64 antivirus engines that checked it flagged this archive, eleven of them major vendors such as Microsoft, BitDefender, ESET, Kaspersky and Sophos, several naming a Windows lock-screen or locker trojan. During the sandbox runs it launched script files through Windows Script Host from a temporary folder and created an autostart entry called SystemLocker.

Full reasoning

The detection picture is unusually broad and consistent for a false positive: 42 of the 64 antivirus engines that checked it flagged the archive, eleven of them from the highest-trust tier, and the naming clusters around lock-screen and locker trojans rather than a single vendor's generic bucket. ESET-NOD32 calls it a Win64/LockScreen variant, Kaspersky labels it a locker heuristic, and Antiy, AhnLab, CTX and VBA32 all follow the same locker theme. The sandbox adds independent behaviour: Windows Script Host was started from a temporary extraction folder against files named like project configuration and browser extension scripts, which is how a malicious archive hides its loader. A Run-key entry named SystemLocker was created for the current user, giving the sample a way to start again at logon, and our behaviour rules flagged the combination of a Temp-folder write and the autostart entry. The sandbox runs themselves returned a clean combined verdict, meaning the locker stage did not fully arm inside the analysis environment, and the contacted-host check found nothing known-malicious, but neither offsets eleven major detections on an archive with observed script execution and persistence. The archive name borrows a well-known AI image tool to look harmless, and it has been circulating since August 2025.

Detailed assessment

What We Detected

This is a ZIP archive, not a program, and that is part of the trick: the contents look like a Stable Diffusion project directory with configuration files and browser-extension folders. Forty-two of the 64 antivirus engines that checked it flagged the archive itself, including eleven of the most reliable ones — Microsoft, BitDefender, ESET-NOD32, Kaspersky, Sophos, Fortinet, Ikarus, Avira, Avast and AVG among them. The most specific naming describes a Windows lock-screen or locker trojan (ESET-NOD32's Win64/LockScreen variant), while the rest use generic trojan names. The archive is not digitally signed.

Threat Behavior

In the sandbox runs the archive was unpacked into a temporary folder and command-shell entries started Windows Script Host on files named like a lint configuration and like JavaScript belonging to bundled extensions. Files inside a fake project folder that are quietly executed by the script host, rather than by the application they appear to belong to, are a well-known way to hide a loader in plain sight.

The run also created an autostart entry under the current user's Run key named SystemLocker, which lines up with the locker naming used by several engines and would restart the payload at every logon. Our behaviour rules flagged the combination of writing into a temporary or AppData location and creating an autostart entry on an unsigned sample. Other recorded traits — long sleeps, process-name changes, checks for user input, and debugger detection — are typical of a locker that tries to outlast removal and resist analysis.

The sample made only ordinary browser and update-related connections, and the destination reputation check found nothing known-malicious. The combined sandbox verdict was clean, which most likely means the final locker stage did not arm inside the test environment rather than that the archive is harmless. Ten files were unpacked during analysis; none of them carried a verdict of their own, so they do not affect the picture either way.

What To Do Now

Do not extract or run this archive. Delete it, and if it has already been unpacked, run a full scan with your antivirus and check the current user's Run registry entries for a value called SystemLocker. If the machine has already shown a locked screen or ransom-style message, treat it as an active infection and use a rescue-disk scan from a clean environment.

Where this verdict could be wrong3 caveats
  • The combined sandbox verdict over the four runs was clean; the locker payload may simply not have armed itself inside the analysis environment.
  • No known-malicious or suspicious destination was found among the eleven contacted hosts, and the file has no public malware-database or community-rule listing.
  • Many of the detections are generic trojan names rather than a single agreed family, and the file is widely submitted (124 sources), which can reflect a renamed or repackaged distribution.

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

Points in its favour
  • The reputation check on the contacted destinations found no known-malicious or suspicious host.
  • No process injection was recorded, and none of the unpacked files carried a malicious verdict of its own.
  • The sample has no listing in public malware-sample databases and no community malware-rule hits.
Points against
  • 42 of the 64 antivirus engines that checked it flagged the archive, including eleven from the most reliable tier: Microsoft, BitDefender, ESET-NOD32, Kaspersky, Sophos, Fortinet, Ikarus and Avira.
  • Several engines describe a Windows lock-screen or locker trojan, and ESET-NOD32 names a specific LockScreen variant.
  • During the sandbox runs, files named like configuration and extension scripts were launched through Windows Script Host from a temporary folder.
  • An autostart entry named SystemLocker was created in the current user's Run registry key.
  • Recorded traits such as long sleeps, process-name changes, user-input checks and debugger detection fit a locker that resists analysis and removal.
  • The archive name borrows a popular AI image-generation tool, and the archive is not digitally signed.

What the test run showed

What the file did on a test computer

Confirmed in the test run

  • Moderate concern: Created a Windows service so it keeps running.

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

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

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

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

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

  • Note: Connected to 8 servers during the test run.

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

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