Is crafter-presets-4.0.0+1.21.11.jar safe?
Only ESET-NOD32 flagged this JAR as a potentially unsafe game tool, but process-injection and defense-impairment mappings warrant caution despite otherwise limited corroboration.
Only 1 of 74 engines flagged the file, while 16 other tier-1 engines reported no detection and the completed sandbox issued no malicious finding. However, runtime evidence mapped activity to T1055 and T1562.001, so the file should be treated cautiously until its source and purpose are verified.

Before opening or running
Do not open or run it until the source and publisher can be verified independently.
If you already opened or ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the publisher's official site and verify its exact hash when possible.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Only 1 of 74 engines flagged the file, while 16 other tier-1 engines reported no detection and the completed sandbox issued no malicious finding. However, runtime evidence mapped activity to T1055 and T1562.001, so the file should be treated cautiously until its source and purpose are verified.
ESET-NOD32 alone identified the JAR as a potentially unsafe Java game tool, with no strong family consensus among the engines. Sixteen other tier-1 engines reported no detection, substantially increasing the chance that the isolated label reflects game-mod or dual-use functionality. One completed sandbox did not issue a malicious verdict, and no malicious child was identified. However, its runtime evidence mapped activity to process injection and impairment of defenses, which are meaningful concerns even though the process-injection mapping does not establish a specific injection method. No external intelligence source corroborated a malware family, while complete host-reputation coverage is unavailable.
What We Detected
ESET-NOD32 was the only engine among 74 to flag the JAR, identifying it as Java/GameTool.J, a potentially unsafe application. The remaining 16 reporting tier-1 engines did not detect it, and there was no strong agreement on a malware family. No corroborating MalwareBazaar, CIRCL, or YARAify match was present.
Threat Behavior
One completed sandbox run did not produce a malicious verdict and recorded no contacted domains, IP addresses, or URLs. The saved evidence nevertheless mapped activity to T1055 and T1562.001, associated with process injection and impairment of defenses. Four written child files were inspected without a malicious result, but their individual classifications remain unknown. A complete contacted-host reputation check was not available.
What To Do Now
Verify that the JAR came from the official project page and that its SHA-256 matches the publisher's release. Keep endpoint protection enabled, and avoid running it on a primary system if the source or expected game-mod functionality cannot be confirmed.
Where this verdict could be wrong3 caveats
- ESET-NOD32 is a tier-1 engine and labeled the file as a potentially unsafe Java game tool, so its isolated detection cannot be dismissed outright.
- The saved runtime mapping includes T1055 and T1562.001, techniques associated with process injection and impairment of defenses, although the sandbox did not issue a malicious verdict.
- contactedHosts=null means host reputation was not checked or saved, and all four dropped children lack definitive verdicts.
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 this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Attempted to impair or bypass security controls.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Transferred a file over the network; malware can use this to fetch additional payloads.
Moderate concern: Checked the environment for virtualisation or analysis tools.
Moderate concern: Checks which security software you have installed.
Note: Collects details about your system.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
