Verdict Malicious

Analyzed , 3 months ago

Is Attachment-Online.exe safe? No, we rate this exact file malicious.

Five major antivirus engines flag the sample with a strong remoteadmin consensus.

Strong evidence · Two or more major antivirus engines agree.

Remove it unless you use it on purpose

Treat as malicious remote-administration tooling; block execution and investigate any systems that ran the file.

What to do now4 steps

This is a hacking tool. It is risky to keep and run, but finding it is not by itself a sign that the device is infected.

What to do

  1. Don't run it unless you got it on purpose for security testing on systems you own. Delete it, then empty the Recycle Bin.

  2. If you didn't put it on the device yourself, delete it and run a full antivirus scan: something else may have brought it.

  3. Tools like this often come with cracked or pirated software. If it came that way, treat the whole download as unsafe and scan everything it installed.

If you already ran it

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

If you opened or installed it

Avoid banking and sign-ins on that device until it is clean. These free MalwareTips guides walk you through it.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

The major family consensus on remoteadmin is decisive. Combined with offensive MITRE techniques and direct-IP a control server, the evidence outweighs the single-submission prevalence. The signer has no clean history and the certificate is revoked, removing any benign-signed-installer protection. Sandbox and file it created signals are neutral but do not override the engine and behavioural consensus.

Where this verdict could be wrong2 caveats
  • If the certificate was legitimately issued to SimpleHelp Ltd for remote-admin tooling, the detections could represent unwanted program rather than malware; however the signer-history record shows zero prior clean samples.
  • No malicious sandbox verdicts and the absence of a known-malicious dropped file reduce the strength of the behavioural signals.

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: Used an unusual way to talk to a server.

  • Moderate concern: Downloaded a file during the test run.

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

  • Moderate concern: Hid files or windows on the test computer.

  • Moderate concern: Contacted a server on an unusual network port.

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.

Threat context

How hacking tools are used

Hacking tools are programs that can switch off security software, test passwords or attack other computers. Security professionals use them on purpose; criminals also bundle them with malware.

Bottom line:Keep it only if you installed it on purpose, and check how it got onto the device if you didn't.

Questions & answers

Short answers to the 9 questions people ask most about this file.

Is Attachment-Online.exe malware?
Attachment-Online.exe is a hacking tool. It is flagged because it can be misused, not because it infects a device by itself. Keep it only if you use it on purpose; otherwise, delete it, then empty the Recycle Bin. 13 of the 71 antivirus engines that checked it flag it.
What is Attachment-Online.exe?

How many antivirus engines detected Attachment-Online.exe?
13 of the 71 antivirus engines that checked it flag Attachment-Online.exe, including Kaspersky and ESET. We weigh which engines flagged it and what else the scan found, not just the count. The rating comes from all the evidence together, not from this count alone.
I already downloaded and ran Attachment-Online.exe — what should I do?
1) If you ran it on purpose, for testing on systems you own, remove it when you are done. 2) If you didn't download it yourself, delete it and run a full antivirus scan: something else may have brought it. 3) If it came with cracked or pirated software, treat that whole download as unsafe, scan everything it installed and change passwords you typed on the device since.
How do I remove Attachment-Online.exe?
To remove Attachment-Online.exe: 1) Delete it, then empty the Recycle Bin. 2) Run a full scan with your antivirus to check that nothing else came with it. 3) Check Settings > Apps and your startup apps for anything you don't recognise.
What kind of program is Attachment-Online.exe?
Antivirus engines classify Attachment-Online.exe as a hacking tool: a program that can switch off security software, test passwords or attack other computers.
Is Attachment-Online.exe digitally signed?
Yes. Attachment-Online.exe has a valid digital signature from SimpleHelp Ltd, 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 Attachment-Online.exe?
The SHA-256 fingerprint of Attachment-Online.exe is b2f3d14809074c84e366827651adef1324f3f93f259aca67924ad555f4c55d66, and its MD5 is c8a4390e8f8eeaa1ad9fe234141a933a. 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 Attachment-Online.exe?
This report reflects the scan on Jul 8, 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.
