Suspicious
Signed Outbyte Camomile installer flagged as PUA/grayware by DrWeb and CrowdStrike, with process injection and direct IP behavior, but contacts vendor site and lacks strong malware consensus.
3d3dbd5885ff6e931f…220d232db0The 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.
Low detection count (2/71) dominated by PUA/grayware labels aligns with security-tool-like filename and classifier heuristic. Verified signature from Outbyte, a known optimizer vendor, but limited signer history raises mild concern. Behavioral signals like T1055 injection and direct IPs are suspicious yet contextualized by legitimate vendor contacts and no malicious runtime outcomes. Absence of tier-1 malware consensus, clean children/hosts, and medium prevalence support PUA over threat. Overall mixed signals warrant caution without clear malicious intent.
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.
Moderate concern: Obfuscates or packs its code to avoid detection.
Moderate concern: Lists running programs — often to find security tools.
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.

What to do now
We couldn't fully clear this file. Treat it with caution.
Don't run it unless you're certain it came from a source you trust.
Check where you got it — an email attachment or a random download link is a red flag.
If you're unsure, delete it. You can always re-download a clean copy from the official source.
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.

YARA & heuristic rule matches
A researcher-curated or high-severity heuristic rule matched this sample. These rules target specific malware families and are near-definitive.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
Evidence"C:\Users\<USER>\Desktop\outbyte-camomile-setup.exe"Sample contacted 2 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.

Safety FAQ
Common questions about Outbyte-camomile-setup.exe, answered from the scan data above.
- Outbyte-camomile-setup.exe is suspicious — treat it as unsafe until you're sure. 2 of 75 antivirus engines flag it (family: Program.Unwanted), which isn't a strong consensus but is enough to be cautious. Don't run it unless you fully trust where it came from, and prefer downloading the software fresh from its official site.
- Outbyte-camomile-setup.exe is a Windows executable program, about 20.6 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
- 2 of 75 antivirus engines flagged Outbyte-camomile-setup.exe, 2 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
- 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 Outbyte-camomile-setup.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 Outbyte-camomile-setup.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.
- Outbyte-camomile-setup.exe is classified as adware or a potentially unwanted program (PUA) — not always destructive, but it bundles ads, trackers, or unwanted changes you didn't ask for. Engines attribute it to the Program.Unwanted 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 — Outbyte-camomile-setup.exe carries a valid digital signature from Outbyte Computing Pty 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 Outbyte-camomile-setup.exe is 3d3dbd5885ff6e931f3d39466279fbd450b53dd40cf2bf78fd41ac220d232db0, and its MD5 is c83f3a8703e2c048c0a754ec10b52f76. 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 April 30, 2026. Because a file's hash never changes, the identity of Outbyte-camomile-setup.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.
