Is geckolib-forge-1.20.1-4.8.4.jar safe?
Zero detections across 75 engines, medium prevalence, and no malicious sandbox or external-intel signals.
The file shows no malicious detections from any engine and has established prevalence. Sandbox activity maps to process-injection techniques but lacks confirmation of malicious intent or malicious dropped children.

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.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The file shows no malicious detections from any engine and has established prevalence. Sandbox activity maps to process-injection techniques but lacks confirmation of malicious intent or malicious dropped children.
All 75 reporting engines returned clean results with zero tier-1 or low-trust malicious flags. The file has been submitted 711 times by 629 sources, indicating widespread legitimate use. Sandbox execution produced three MITRE techniques flagged as offensive, yet the sandbox itself did not return a malicious verdict and no dropped children were malicious. External intelligence sources returned no hits. The single heuristic trigger maps observed behaviour to T1055 but does not prove malicious intent.
What We Detected
75 antivirus engines scanned the JAR; none flagged it malicious. Sandbox execution recorded typical Java runtime behaviour plus three MITRE techniques (T1055, T1543.002, T1562.001) without producing a malicious verdict or malicious child files.
Threat Behavior
No C2 domains, no malicious dropped children, and no external-intel corroboration. The observed techniques are consistent with legitimate mod-loader or debugging activity common in Minecraft Forge libraries.
What To Do Now
Keep endpoint protection enabled. The file can be used if obtained from the official GeckoLib repository or CurseForge; verify the SHA-256 hash before execution.
Where this verdict could be wrong1 caveat
- behaviour.offensiveTechniques includes T1055 (Process Injection) — sandbox evidence maps to MITRE technique but does not prove malicious intent or injection method.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Zero detections from 75 engines
- Medium prevalence across 629 sources
- No malicious external-intel hits
- No malicious dropped children
- Sandbox mapped activity to T1055 (Process Injection) without proving malicious intent
The evidence supports safe use when downloaded from trusted sources; continue running endpoint protection.

MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
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.
