Why we think so
3 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 49 antivirus engines that checked it flagged this installer, and over 1,400 distinct sources have submitted it. A sandbox run showed normal launcher installation and contacts to Mojang and the SKlauncher metadata server.
None of the 49 antivirus engines that checked it flagged the file, and seven major antivirus engines reported it clean, though several others timed out on this 128 MB installer. It has been seen from 1,427 distinct sources in 23 days, matching a popular launcher release. The sandbox run was clean and showed an Electron-style app installing to the user profile, writing uninstall entries and using PowerShell to check for its own running processes. Technique mappings for credential access and injection appeared, but no injected process or credential target was recorded. All seven contacted hosts were checked and none are known malicious.
What We Detected
None of the 49 antivirus engines that checked it flagged this SKlauncher 4.0.54 installer; Avira, Microsoft, Fortinet, Ikarus and F-Secure returned clean, while some engines timed out on the large file. It is an unsigned NSIS-style installer seen from more than 1,400 sources.
Threat Behavior
The sandbox run was clean. The installer placed sklauncher.exe under the user's local Programs folder, registered an uninstaller, and ran PowerShell checks for its own processes. Network contacts went to Mojang's metadata service, the SKlauncher metadata host and a DNS provider, none known malicious. Technique tags for injection and credential access were raised without any identified target.
What To Do Now
Use only the copy from the official SKlauncher site, keep your antivirus enabled, and rescan if you got the installer from a mirror or a link shared in chat.
Where this verdict could be wrong3 caveats
- The installer is unsigned, so there is no publisher signature confirming who built it.
- Seventeen engines, including several major ones, timed out on this large file, so engine coverage is incomplete.
- The single sandbox run was mapped to credential-access and process-injection techniques, though no injected target or credential read was identified.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 49 antivirus engines that checked it flagged the file.
- Submitted by more than 1,400 distinct sources within about three weeks.
- The sandbox run finished clean and showed ordinary launcher installation.
- Network contacts were limited to Mojang and the launcher's own servers, none known malicious.
- The installer is not digitally signed.
- Several antivirus engines timed out and did not return a result.
- Sandbox analysis tagged generic credential-access and injection techniques without a confirmed target.
