Verdict Suspicious
Is Windows
Only Skyhigh flagged this new batch script, while 18 major antivirus engines and observed activity in the test run provided no corroboration for its generic backdoor label.
Read the whole reasonShow less
Why Suspicious? One antivirus engine (Skyhigh (McAfee)) flags it; 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 run 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 ran it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Why we think so
3 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
One of the 61 antivirus engines that checked it flagged the script with a generic backdoor-like label, while all 18 reporting major antivirus engines were silent. Observation from the test run showed a Windows permission check but no high-risk technique, injection, persistence, or malicious sandbox assessment; however, the file was first seen on Oct 16, 2026 and lacks established reputation.
Skyhigh was the only engine to flag the script, using a generic backdoor-like behavioural label rather than naming a recognized family. None of the 18 major antivirus engines reported a detection. Observation from the test run showed command-shell execution and a permission check against a protected Windows path, but no high-risk technique, process injection, persistence, file it created, or malicious sandbox assessment. That pattern weakens the isolated detection and makes a false alarm plausible. Nevertheless, the script has only one submission, was first seen on Oct 16, 2026, and lacks independent intelligence or comparable historical samples, so the evidence does not establish its intent confidently.
What We Detected
Skyhigh was the only engine among 75 to flag the batch script, assigning the generic label “BehavesLike.Backdoor.zt.” None of the 18 major antivirus engines reported a detection, and no recognized malware family was identified.
Threat Behavior
The observed commands launched the script through the Windows command interpreter and used cacls.exe against a protected system path, a pattern commonly used to test administrator permissions. The run did not record process injection, persistence changes, files it created, network contacts, high-risk techniques, or a malicious sandbox assessment. A complete contacted-host reputation result is unavailable, although the observed run recorded no sample contacts.
What To Do Now
Because batch scripts can execute powerful system commands and this file has almost no reputation, inspect its plain-text contents before running it. If its source or expected actions cannot be verified, keep security software enabled and test it only in an isolated environment.
Where this verdict could be wrong2 caveats
- Skyhigh identified backdoor-like behaviour, but no other engine or evidence from the test run corroborated that generic label.
- The file is and has only one submitter, so its reputation is not yet established.
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 18 major antivirus engines reported a detection.
- Observation from the test run recorded no process injection, persistence, files it created, or high-risk techniques.
- No malicious sandbox assessment was recorded.
- The script was first seen on Oct 16, 2026 and has been submitted by one source.
- Skyhigh reported generic backdoor-like behaviour.
- No established publisher identity, historical comparisons, or independent intelligence is available.
