Malicious
Tier-1 engines converge on remoteadmin family with process-injection and direct-IP C2 behaviour.
b2f3d14809074c84e3…55f4c55d66The reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
The tier-1 family consensus on remoteadmin is decisive. Combined with offensive MITRE techniques and direct-IP C2, 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 child-file signals are neutral but do not override the engine and behavioural consensus.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

What this file does
What it attempted when executed in an isolated sandbox
High concern: Hides inside another running program to evade antivirus.
High concern: Talks to a remote server to take commands or send out your data.
High concern: Downloads more malware onto your PC.
Moderate concern: Obfuscates or packs its code to avoid detection.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Deletes traces of itself to cover its tracks.
Moderate concern: Scans through your files and folders.
Translated from the file's technical behaviour during analysis. It never ran on your device.
Threat context
How hacktools are abused
This is a hacking or cracking tool — the kind used to bypass software licences, generate fake keys, or attack other systems. Even when the tool 'works', these downloads very often carry hidden malware.
Bottom line:Running one means trusting an anonymous author with full access to your PC — rarely worth the risk.
What to do now
This file is dangerous. Treat it as harmful and remove it.
Don't open or run this file. Delete it from your Downloads (or wherever you saved it), then empty the Recycle Bin.
If you already opened it, disconnect from the internet and run a full scan with your antivirus — Windows Security, built into Windows, is sufficient.
If you typed any passwords while it was open, change them from a device you trust.
In future, only download software from the official website or an official app store.

Safety FAQ
Common questions about Attachment-Online.exe, answered from the scan data above.
- Yes — Attachment-Online.exe is malicious, so do not run it, and delete it. 13 of 75 antivirus engines flag it (family: remoteadmin). It behaves as a hacktool — dual-use offensive tooling that is dangerous regardless of intent. If you've already run it, see the removal and recovery steps below.
- Attachment-Online.exe is a Windows executable program (application/x-msdownload), about 1.6 MB. Our analysis identifies it as malicious (family: remoteadmin) — a hacktool — dual-use offensive tooling that is dangerous regardless of intent. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
- 13 of 75 antivirus engines flagged Attachment-Online.exe, 13 of them as outright malicious. A detection rate at this level is a reliable signal that the file is dangerous.
- Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
- To remove Attachment-Online.exe: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete the original Attachment-Online.exe file and empty the Recycle Bin/Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
- Attachment-Online.exe is classified as a hacktool — dual-use offensive tooling that is dangerous regardless of intent. Engines attribute it to the remoteadmin family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
- Yes — Attachment-Online.exe carries a valid digital signature from SimpleHelp Ltd, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
- The SHA-256 hash of Attachment-Online.exe is b2f3d14809074c84e366827651adef1324f3f93f259aca67924ad555f4c55d66, and its MD5 is c8a4390e8f8eeaa1ad9fe234141a933a. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- This report reflects the scan run on June 1, 2026. Because a file's hash never changes, the identity of Attachment-Online.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
