Verdict Suspicious

Analyzed , 5 months ago

Is Argon.jar safe? Treat it as suspicious.

Zero engines flagged the file malicious despite 59 reports.

Why Suspicious? Offensive MITRE techniques and T1562.001.

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.

Not sure what to do?

Ask the MalwareTips community before you run it. If you already ran it, follow the cleanup guide.

What the test run showed

What the file did on a test computer

Confirmed in the test run

  • 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.

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

  • 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 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.

Questions & answers

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

Is Argon.jar safe, or is it malware?
Argon.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 Argon.jar?
Argon.jar is a Java program (JAR), about 342.7 kB. VirusTotal first saw it on Dec 2, 2025.
How many antivirus engines detected Argon.jar?
None of the 59 antivirus engines that checked it flag Argon.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 Argon.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 Argon.jar?
The SHA-256 fingerprint of Argon.jar is 0ba5c89b4873e2a24a31d316a090cc98353ee1d04881695cafee18d0bb3390fd, and its MD5 is 8f57ba7e132968ec75473e6f0e7b71b3. 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 Argon.jar?
This report reflects the scan on May 17, 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.
