Is LegacyLauncher_source.zip safe?
ZIP archive shows only two low-trust detections and benign Gradle/Java build behaviour.
Two low-trust engines flagged the archive; no tier-1 detections, no malicious children, and sandbox activity matches a legitimate Gradle build chain. no complete contacted-host reputation result was available.

Before opening or extracting
Open or extract it only when its sender or download source has been independently verified.
If you already opened or extracted 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.
Two low-trust engines flagged the archive; no tier-1 detections, no malicious children, and sandbox activity matches a legitimate Gradle build chain. no complete contacted-host reputation result was available.
The two detections come from MaxSecure and Sangfor, neither tier-1, and no family consensus exists. Sandbox traces show a standard Gradle wrapper and Java launcher, not malware. Ten dropped children and two inspected no complete contacted-host reputation result was available. Medium prevalence and absence of external-intel hits further support a benign verdict.
What We Detected
LegacyLauncher_source.zip triggered two low-trust engines (MaxSecure Trojan.Malware.300983.susgen, Sangfor Trojan.Win32.Save.a). No tier-1 engine raised an alert. Sandbox execution revealed a Gradle build process using Java 8 and the Gradle wrapper, writing typical cache and temporary files.
Threat Behavior
Three MITRE techniques were mapped (T1055, T1543.002, T1562.001), but they align with Gradle’s process-management and permission-adjustment steps rather than malicious injection. Eighteen direct-IP contacts were observed; none matched known-malicious hosts in our cache. Ten child files were produced, none flagged malicious.
What To Do Now
The archive can be treated as safe for development use. Keep endpoint protection enabled and verify the source before building or distributing the resulting binaries.
- tier1Malicious=0
- contactedHosts clean
- droppedChildren clean
- medium prevalence
Proceed with normal caution; the file shows no credible malicious indicators.
Coverage & freshness
Complete means the check returned a usable result. It does not mean the file is safe.

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.
