Verdict Safe
Is geckolib-
Zero detections across 75 engines, medium prevalence, and no malicious sandbox or external-intel signals.
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.

Why we think so
1 point against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The file shows no malicious detections from any engine and has established prevalence.
All 75 reporting engines returned clean results with zero major or less reliable 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 files it created were malicious. External intelligence sources returned no hits. The single rule-based trigger maps observed behaviour to but does not prove malicious intent.
What We Detected
75 antivirus engines scanned the JAR; none flagged it malicious. Sandbox execution recorded typical Java behaviour in the test run plus three MITRE techniques (T1055, T1543.002, T1562.001) without producing a malicious verdict or malicious files it created.
Threat Behavior
No control-server domains, no malicious files it created, 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 security software enabled. The file can be used if obtained from the official GeckoLib repository or CurseForge; verify the SHA-256 hash before execution.
- Zero detections from 75 engines
- Medium prevalence across 629 sources
- No malicious external-intel hits
- No malicious files it created
- Sandbox mapped activity to T1055 (Process Injection) without proving malicious intent

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
