Verdict Suspicious

Analyzed , 1 month ago

Is Numby-Hack-2.6.24.jar.disabled safe? Treat it as suspicious.

All 64 antivirus engines that checked it produced no malicious or suspicious detection, including 17 major contributors, and the sandbox issued no malicious verdict.

Read the whole reasonShow less

Why Suspicious? Runtime recorded offensive 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

Keep protection enabled and obtain the JAR from a verified source before use. If its origin cannot be established, delete it or examine it only in a network-restricted virtual machine.

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

The strongest evidence is the absence of detections across 75 antivirus engines, including all 17 major contributors. One completed sandbox run did not issue a malicious verdict, and none of the five inspected child hashes was identified as malicious. However, the run recorded and T1562.001, which can indicate service execution and interference with defenses. A low-severity rule also noted direct contact with 162.159.36.2, and no complete host-reputation result is available. The unsupported community claim of a named RAT or stealer family is insufficient to outweigh the independent evidence, but the runtime signals prevent an unqualified benign assessment.

Where this verdict could be wrong3 caveats
  • The runtime recorded and T1562.001, techniques associated with service execution and impairment of defenses.
  • The low-severity one of our behaviour rules recorded contact with 162.159.36.2, but host reputation was not checked or saved.
  • communityComments[0] alleges WEEDHACK and RAT/stealer activity, but it has 0 votes and lacks corroboration from engines, sandbox verdicts, or external intelligence.

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: 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.

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

Is Numby-Hack-2.6.24.jar.disabled safe, or is it malware?
Numby-Hack-2.6.24.jar.disabled 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 Numby-Hack-2.6.24.jar.disabled?
Numby-Hack-2.6.24.jar.disabled is a Java program (JAR), about 261.8 kB. VirusTotal first saw it on Apr 29, 2026.
How many antivirus engines detected Numby-Hack-2.6.24.jar.disabled?
None of the 64 antivirus engines that checked it flag Numby-Hack-2.6.24.jar.disabled. 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.
What should I do if I already opened or ran Numby-Hack-2.6.24.jar.disabled?
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.

The SHA-256 fingerprint of Numby-Hack-2.6.24.jar.disabled is 1b612c3e3a8aea0cafaea5a5b231132267fa0815d8df4ee2b159ec4b753271bb, and its MD5 is 85aad9b8fb81753ce974e35ccdeb8707. 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 Numby-Hack-2.6.24.jar.disabled?
This report reflects the scan on Sep 8, 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.
