Why Suspicious? YARAify matched 6 community rules.

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

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

Treat the installer with caution; run it only inside a disposable VM or after confirming its checksum with the vendor.

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.

The reasoning behind this verdict

Analyst conclusion

Zero detections across 75 engines and a verified signature reduce the likelihood of commodity malware. Samples built with the same import table have produced mixed verdicts, and the signer has no historical track record. These conflicting signals place the file in the suspicious band.

Where this verdict could be wrong2 caveats
  • YARAify returned 6 rule hits, but rules are generic (Borland, TLS callbacks, digital certificate) rather than family-specific malware signatures.
  • Community comment claims 'Malware' with score 100/100, yet no engine detection corroborates that claim.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

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.

  • Moderate concern: Unpacked hidden content while it ran.

  • Moderate concern: Checked whether it was running on a test computer.

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

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

  • Note: Deleted files or logs during the test run (installers often clean up after themselves).

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

  • Not confirmed: A sandbox rule tagged this run as code injection, but no injected program 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.

Questions & answers

Short answers to the 7 questions people ask most about this file.

Is Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe safe, or is it malware?
Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe is rated Suspicious: some signs point to a problem, but nothing confirms it is harmful. No antivirus engine flags it; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run. Don't install it unless you're sure where it came from. If you need the software, download a fresh installer from the developer's own website.
What is Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe?
Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe is a software installer, about 7.5 MB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Sep 5, 2025.
How many antivirus engines detected Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe?
None of the 65 antivirus engines that checked it flag Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe. A clean antivirus result is not proof of safety; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run.
I already downloaded and installed Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe — what should I do?
No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
Is Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe digitally signed?
Yes. Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe has a valid digital signature from CRYSTAL DEVELOPMENT, LLC, which shows the file hasn't been changed since that publisher signed it. Malware is sometimes signed with stolen certificates, so a signature alone isn't proof of safety.
What is the SHA-256 hash of Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe?
The SHA-256 fingerprint of Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe is 7d98f239dd3585dd8da29130aacbcda6617584494abfb2ed4bfe75265aafd5ec, and its MD5 is 855c64d8ec5dd35749fecbac2334aa9f. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
How up to date is this analysis of Alpine_Client_Setup_1_8_5_x86_64_8dd1bd0c66.exe?
This report reflects the scan on Oct 17, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
