Verdict Suspicious

Analyzed , 1 month ago

Is LuluNotes_Setup.exe safe? Treat it as suspicious.

Unsigned NSIS installer with one detection from a major antivirus engine and no sandbox malice.

Why Suspicious? 4 antivirus engines flag it; nothing else confirms it.

Limited evidence · One sign points to a problem; nothing else confirms it.

Don't install it until you know where it came from

Treat as suspicious; do not run without additional verification or a signed build from the publisher.

What to do now4 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't install it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. 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 installed it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Not sure what to do?

Ask the MalwareTips community before you run it. If you already ran it, follow the cleanup guide.

What the test run showed

What the file did on a test computer

Confirmed in the test run

  • Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).

  • Moderate concern: Ran commands or a script on the test computer.

  • Note: Read the user name of the test computer.

  • Note: Listed the programs running on the test computer.

  • Note: Read basic details of the test computer, such as its Windows version.

  • Note: Looked through folders on the test computer (most installers do this).

  • Note: Loaded extra code modules while running.

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.

  • Not confirmed: A sandbox rule tagged this run as setting up auto-start; no auto-start entry was recorded.

  • Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.

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.
