Is strength-1.0.0 (1).jar safe?
No antivirus engine detected this JAR, including 17 tier-1 products, although its very recent appearance and absent runtime data limit assurance.
All 75 antivirus engines returned no detection, including 17 tier-1 products, and no external intelligence source matched the sample. However, it was first observed today with only one submission, and no completed sandbox or network-host assessment is available, so normal source verification remains appropriate.

Before opening or running
Open or run it only when its publisher and download source have been independently verified.
If you already opened or ran it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 75 antivirus engines returned no detection, including 17 tier-1 products, and no external intelligence source matched the sample. However, it was first observed today with only one submission, and no completed sandbox or network-host assessment is available, so normal source verification remains appropriate.
The strongest evidence is the complete absence of detections across 75 antivirus engines, with all 17 tier-1 participants reporting no match. Researcher-curated intelligence also produced no YARA rules, known-malware reference, or recognized sample match. The file is nevertheless new and rare, having only one recorded submission, so its reputation is not established. No completed runtime observation exists, and no complete contacted-host reputation result is available. Prior safe decisions are only broad file-type matches to unrelated samples and contribute little beyond the direct scan results.
What We Detected
None of the 75 antivirus engines flagged the JAR, and all 17 tier-1 engines reported no detection. No YARAify rule, MalwareBazaar match, CIRCL record, confirmed hacktool label, or brand mismatch was present.
Threat Behavior
No completed sandbox run is available, so the file's runtime behavior was not observed. The contacted-host cross-check was also unavailable, meaning there is no complete network-reputation result to assess.
What To Do Now
Confirm that the JAR came from the expected developer or official distribution channel before running it. Keep endpoint protection enabled and consider testing it in an isolated environment if its origin is uncertain, especially because the sample was first observed today.
Where this verdict could be wrong3 caveats
- The file is newly observed and has only one submission, so detection signatures and reputation may not yet be mature.
- behaviour=null means no runtime execution was observed, and contactedHosts=null means no complete host-reputation result is available.
- The five prior safe samples are file-type-only matches to unrelated formats and therefore offer weak similarity evidence.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus engines detected a threat
- 17 tier-1 engines reported no detection
- No YARAify, MalwareBazaar, or CIRCL hit
- No malicious child or confirmed hacktool evidence
- No brand mismatch detected
- First observed today with only one recorded submission
- No completed runtime behavior observation
- No complete contacted-host reputation result
- No applicable code-signing identity for publisher verification
Use the file only if it came from the expected developer or an official channel. Keep security protection enabled and isolate execution when the source cannot be verified.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Open or run it only when its publisher and download source have been independently verified.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
