Is kk9ur64hu.exe safe?
Unsigned 30 KB executable submitted for the first time today with zero engine detections.
No antivirus engine flagged the file and sandbox behaviour was benign, but the sample is brand-new, unsigned, and has only one prior submission. Coverage is too low to reach a definitive verdict.

Before running
Treat the file as unverified and avoid running it until more evidence is available.
If you already ran it
Run a full device scan. If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source.
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.
No antivirus engine flagged the file and sandbox behaviour was benign, but the sample is brand-new, unsigned, and has only one prior submission. Coverage is too low to reach a definitive verdict.
Seventy-five engines returned zero malicious detections, including seventeen tier-1 engines. The file is unsigned and appeared for the first time today, so no historical reputation exists. A single sandbox run observed only ambient techniques and no complete contacted-host reputation result was available contact. The lone similar-hash record also carried an unknown verdict due to low coverage. These factors together leave the file in the unknown category.
What We Detected
Zero detections across 75 engines; file is a 29 696-byte unsigned Win32 executable. Sandbox execution produced four ambient MITRE techniques and no malicious indicators.
Threat Behavior
No C2 traffic, dropped children, or persistence mechanisms were observed. The sample is too recent for meaningful prevalence data.
What To Do Now
Keep endpoint protection enabled. Re-scan after additional submissions increase coverage, or run the file in an isolated environment if execution is required.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.

What to do now
There isn't enough information to give this file a clear rating.
- Recovery step 01
Be cautious — an unknown rating is not the same as a clean bill of health.
- Recovery step 02
Run it only when it came from the developer's official site or another source you independently trust.
- Recovery step 03
When in doubt, don't run it — or scan it again later once it's more widely seen.
