Verdict Suspicious

Analyzed , 13 days ago

Is catppuccin-addon-2.3.0+mc1.21.11.jar safe? Treat it as suspicious.

No antivirus engine detected this JAR, but one conflicting sandbox verdict and unconfirmed and mappings justify caution pending source verification.

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 66 antivirus engines that checked it flagged the JAR, and no malware family or malicious child was identified. However, one of two sandbox runs raised an alert and mapped possible process injection and service activity, while the other run was clean; those conflicting results prevent an unqualified benign assessment.

Where this verdict could be wrong3 caveats
  • One sandbox produced a malware/trojan verdict and mapped plus T1543.002, which warrants caution despite the absence of antivirus detections.
  • The file was first observed on Oct 8, 2026, so its reputation and prevalence history remain limited.
  • No complete contacted-host reputation result is available, although the completed runs recorded no sample contacts.

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 creating a service; no new service 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.

Questions & answers

Short answers to the 6 questions people ask most about this file.

Is catppuccin-addon-2.3.0+mc1.21.11.jar safe, or is it malware?
catppuccin-addon-2.3.0+mc1.21.11.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 catppuccin-addon-2.3.0+mc1.21.11.jar?
catppuccin-addon-2.3.0+mc1.21.11.jar is a Java program (JAR), about 429.1 kB. VirusTotal first saw it on Oct 8, 2026.
How many antivirus engines detected catppuccin-addon-2.3.0+mc1.21.11.jar?
None of the 66 antivirus engines that checked it flag catppuccin-addon-2.3.0+mc1.21.11.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 catppuccin-addon-2.3.0+mc1.21.11.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 catppuccin-addon-2.3.0+mc1.21.11.jar?
The SHA-256 fingerprint of catppuccin-addon-2.3.0+mc1.21.11.jar is 08b1dd9b4fb33bad11da3619b8b68fc4068a03ac6830ca733522a61194a5be58, and its MD5 is 2bf4f73c62c4d5fa225b41b3f0a91450. 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 catppuccin-addon-2.3.0+mc1.21.11.jar?
This report reflects the scan on Oct 13, 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.
