Is LuaTools-win-Portable.zip safe?
ZIP archive containing Java executables flagged by four engines with no tier-1 consensus and no malicious dropped children.
Four of 75 engines flagged the archive, all tier-2 or low-trust, with labels such as RiskWare.SteamHack and Trojan.Win32.Save.a. Sandbox activity shows Java execution and a direct-IP connection, but no malicious children or external-intel hits were found.

Before opening or extracting
Do not open or extract it until the source can be verified independently.
If you already opened or extracted it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the original trusted source and verify its exact hash when possible.
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.
Four of 75 engines flagged the archive, all tier-2 or low-trust, with labels such as RiskWare.SteamHack and Trojan.Win32.Save.a. Sandbox activity shows Java execution and a direct-IP connection, but no malicious children or external-intel hits were found.
The absence of tier-1 detections and the lack of any confirmed malicious child or external-intel corroboration keep the file out of the malicious category. However, the presence of offensive MITRE technique T1543.002 and the direct-IP contact flagged by a heuristic rule create enough uncertainty to avoid a clean verdict. The file is common_new, portable-looking, and only five days old, so its reputation is still forming.
What We Detected
Four engines (DeepInstinct, Malwarebytes, Sangfor, MaxSecure) returned malicious labels; none are tier-1. The archive contains Java JARs that executed under Java 8 and contacted IP 162.159.36.2 without an associated domain.
Threat Behavior
Observed MITRE technique T1543.002 (new service creation) is listed as offensive, yet sandbox verdicts were empty and no dropped child was flagged malicious. No YARA, CIRCL or MalwareBazaar hits exist.
What To Do Now
Do not run the archive on production systems. Keep endpoint protection enabled and monitor for any follow-up submissions that might add tier-1 detections or malicious child verdicts.
- No tier-1 malicious detections
- No malicious dropped children
- No external-intel hits
- Direct-IP contact without domain (162.159.36.2)
- Offensive MITRE technique T1543.002 observed
- Low-trust engine detections present
Treat the archive as untrusted until additional tier-1 detections or sandbox evidence appear; keep security software active.

What this file does
Observed actions and their security significance
High concern: Created or modified a system service, which can keep code running.
Note: Connected to 1 server during sandbox analysis.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
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.
