Analyzed , 2 days ago

Is 3trouser-streak-1.6.9-1.21.11.jar safe? Treat it as suspicious.

This Java mod archive is not flagged by any of 75 antivirus engines, but sandbox results are split between a malware label and a clean result, leaving it unresolved.

Read the whole reasonShow less

Why Suspicious? One sandbox test run rated it malicious while another found nothing; nothing else confirms it.

Limited evidence · One sign points to a problem; nothing else confirms it.

Don't open or run it until you know where it came from

If it came from a link, an attachment or a stranger, delete it.

What to do now4 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't open or run it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.

If you already opened or ran it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

The reasoning behind this verdict

Analyst conclusion

None of the 65 antivirus engines that checked it flagged this Java archive, and no threat database lists it. However, the sandbox runs produced mixed labels: malware/trojan alongside clean. No concrete malicious behaviour backs up the malware label, so the evidence does not support a firm call either way.

Where this verdict could be wrong2 caveats
  • The combined sandbox verdict label includes a malware/trojan label, but no injected process, malicious contact or malicious dropped file backs it up.
  • No antivirus engine flags the file and 82 separate sources submitted it, which fits a widely shared game mod more than malware.

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).

  • Moderate concern: Ran commands or a script on the 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: Loaded extra code modules while running.

  • 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 code injection, but no injected program was recorded.

  • Not confirmed: A sandbox rule tagged this run as downloading a file, but no download 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.

Is 3trouser-streak-1.6.9-1.21.11.jar safe, or is it malware?
3trouser-streak-1.6.9-1.21.11.jar is rated Suspicious: some signs point to a problem, but nothing confirms it is harmful. No antivirus engine flags it; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run. Don't open or run it unless you're sure where it came from. If you need it, download it again from the project's own website.
What is 3trouser-streak-1.6.9-1.21.11.jar?

How many antivirus engines detected 3trouser-streak-1.6.9-1.21.11.jar?
None of the 65 antivirus engines that checked it flag 3trouser-streak-1.6.9-1.21.11.jar. A clean antivirus result is not proof of safety; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run.
I already downloaded and opened or ran 3trouser-streak-1.6.9-1.21.11.jar — what should I do?
No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
What is the SHA-256 hash of 3trouser-streak-1.6.9-1.21.11.jar?
The SHA-256 fingerprint of 3trouser-streak-1.6.9-1.21.11.jar is cb199f6eb8d22e747dbbb354540aeddca2528a33f09e6ffc79adea39b4977cff, and its MD5 is 9eee72594ec243900fe77d589e3cc1f8. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
How up to date is this analysis of 3trouser-streak-1.6.9-1.21.11.jar?
This report reflects the scan on Oct 23, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.

This report and its SHA-256 fingerprint are public, so the next person who checks the same file gets an instant answer; documents and images are listed by type instead of their file name. A file we had not seen before is uploaded to VirusTotal, whose security partners and subscribers can download it; MalwareTips deletes its own copy after the scan. If you ran this file and are worried, scan your device with up-to-date security software.
