Is forge-26.2-65.1.0-installer.jar safe?
No antivirus engine detected malware, while moderate prevalence supports legitimacy, though unusual runtime techniques and unchecked direct-IP contacts warrant source verification.
All 74 antivirus engines avoided flagging this JAR, including 17 tier-1 engines, and the file has circulated among 600 sources. One sandbox recorded offensive technique mappings and four direct-IP contacts, but produced no malicious verdict; because host reputation and child-file conclusions are incomplete, use only a trusted Forge release source.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 74 antivirus engines avoided flagging this JAR, including 17 tier-1 engines, and the file has circulated among 600 sources. One sandbox recorded offensive technique mappings and four direct-IP contacts, but produced no malicious verdict; because host reputation and child-file conclusions are incomplete, use only a trusted Forge release source.
Static scanning found no detections across 74 antivirus engines, with all 17 reporting tier-1 engines returning no malware finding. The file has 669 submissions from 600 sources, which weighs against a newly introduced impersonator. One completed sandbox run did not issue a malicious verdict, but it mapped activity to T1055, T1543.002, and T1562.001. It also observed four direct-IP contacts, and no complete host-reputation result is available because contactedHosts is null. Ten dropped children were inspected without a confirmed malicious child, although their individual verdicts remain unknown. Overall, the broad detection silence and prevalence outweigh the uncorroborated behavioural heuristics, with residual caution appropriate.
What We Detected
The JAR received 0 malicious and 0 suspicious findings across 74 antivirus engines. Seventeen tier-1 engines, including Avast, BitDefender, ESET-NOD32, Kaspersky, and Microsoft, reported no detection. The sample also has 669 submissions from 600 sources, indicating meaningful circulation.
Threat Behavior
One completed sandbox run produced no malicious sandbox verdict, but its telemetry mapped activity to T1055, T1543.002, and T1562.001. Four external IP addresses were contacted without application-domain context. Their reputations cannot be characterized because contactedHosts is null, and all ten dropped children still have unknown individual verdicts despite no confirmed malicious child.
What To Do Now
Confirm the SHA-256 and obtain the installer from the official Forge distribution channel. Keep endpoint protection enabled and avoid running copies obtained from advertisements, file mirrors, or unsolicited links.
Where this verdict could be wrong3 caveats
- The MalwareTips.Synth.ProcessInjection heuristic maps activity to T1055, which is a meaningful offensive signal despite the absence of antivirus detections.
- Four direct IP addresses were contacted, and contactedHosts=null means their reputation was not completely checked.
- All ten inspected dropped children have unknown verdicts, so droppedChildren.hasMaliciousChild=false does not establish that every child is benign.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 antivirus engines reported a malicious or suspicious result.
- tier1Malicious=0 and tier1ReportedClean=17.
- behaviour.hasMaliciousSandboxVerdict=false.
- droppedChildren.hasMaliciousChild=false.
- 600 unique sources account for 669 submissions.
- Runtime telemetry mapped activity to T1055, T1543.002, and T1562.001.
- Four direct-IP contacts were observed without a complete host-reputation check.
- All ten dropped children retain unknown individual verdicts.
- The JAR format does not provide an applicable code-signing result.
Use the file only if its SHA-256 matches the installer published through the official Forge release channel. Keep antivirus and endpoint protection enabled during download and execution.

Detection sources at a glance
The available sources did not agree on a named threat category.
Available reference checks returned no match, but at least one source was unavailable. This is not a clean result.
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.
Evidence"C:\Program Files\Java\jre-1.8\bin\javaw.exe" -jar "C:\Users\<USER>\Desktop\runtime.jar"The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
