Verdict Suspicious
Is Lua
ZIP archive containing Java executables flagged by four engines with no major consensus and no malicious files it created.
Read the whole reasonShow less
Why Suspicious? 4 antivirus engines flag it, but no major engine agrees; nothing else confirms it.
Limited evidence · One sign points to a problem; nothing else confirms it.
If it came from a link, an attachment or a stranger, delete it.
What to do now4 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't open or extract it unless you're sure where it came from.
Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.
If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.
If you already opened or extracted it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Why we think so
2 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Four of the 67 antivirus engines that checked it flagged the archive, all smaller or less reliable, with labels such as RiskWare.SteamHack and Trojan.Win32.Save.a.
The absence of major 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. No complete contacted-host reputation result was available. The file is widely seen but 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 major. 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 file it created was flagged malicious. No YARA, CIRCL or MalwareBazaar hits exist.
What To Do Now
Do not run the archive on production systems. Keep security software enabled and monitor for any follow-up submissions that might add major detections or malicious child verdicts.
- No malicious detections from major antivirus engines
- No malicious files it created
- No external-intel hits
- Offensive MITRE technique observed
- Less reliable engine detections present

Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as creating a service; no new service was recorded.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.
