What kind of malware is Triton RAT?
While checking malware samples submitted to VirusTotal, we discovered Triton RAT, a Remote Access Trojan allowing the attackers to perform various malicious activities on the infected device. In most cases, RATs are used to steal sensitive information and (or) deliver additional malicious payloads. Victims should remove Triton RAT immediately.
More about Triton RAT
Triton RAT has various capabilities, including the ability to log keystrokes, download and upload files, execute shell commands, pilfer data saved in the clipboard, collect system information, steal saved passwords, and access the victim's webcam. The malware can also change the victim's wallpaper and record screen.
Additionally, Triton RAT can extract Roblox security cookies (stored in Brave, Chrome, Chromium, Edge, Firefox, and Opera browsers), gather Wi-Fi details, and evade detection. Keylogging enables Triton RAT to capture every keystroke typed by the victim, including sensitive information, such as usernames, passwords, credit card details, personal messages, and other confidential data.
File downloading and uploading allows Triton RAT to transfer files between the infected system and the attacker. Cybercriminals can use this feature to download malware (and other payloads) and upload stolen files, such as documents, images, or other sensitive data.
Triton RAT's capability to execute shell commands allows the attackers to control the system remotely, perform tasks like file manipulation, process termination, or even install additional malicious software. The ability to steal information from the clipboard provides cybercriminals with access to anything stored in it (e.g., passwords or credit card details).
Triton RAT is also capable of stealing Roblox security cookies, which are browser cookies that store user session data. These cookies can be used to access a Roblox account by bypassing two-factor authentication (2FA). Other capabilities allow cybercriminals to access the same or other sensitive information.
All the stolen data is transmitted to Telegram through a Telegram bot.

Possible damage
In conclusion, Triton RAT is a dangerous malware with a wide range of capabilities designed to compromise user privacy and security. Triton RAT's numerous functions make it a formidable tool for attackers, enabling them to exfiltrate valuable data, control the infected device, plant more malware, and perform other malicious actions.
More examples of RATs are Bee RAT, StilachiRAT, and NonEuclid RAT.
How did Triton RAT infiltrate my computer?
Threat actors employ multiple methods to trick users into infecting computers. They often plant malware in pirated software, cracking tools, and key generators or use tactics like technical support scams, deceptive and malicious ads, and fraudulent emails with malicious attachments or links.
Additionally, threat actors can distribute malware via peer-to-peer (P2P) networks, third-party downloaders, compromised websites, infected USB drives, or by exploiting software vulnerabilities. The primary objective is to manipulate users into performing certain actions that lead to system compromise.
How to avoid installation of malware?
Keep your operating system and software up to date, and make it a habit to regularly scan your system using a trusted security tool to spot any potential threats. Exercise caution when opening email attachments or clicking on links, especially if they come from unfamiliar or suspicious sources.
Avoid interacting with suspicious links, pop-ups, or ads from untrustworthy websites, and avoid granting them notification permissions. Always download software and files from legitimate sources or well-known app stores, steering clear of third-party sites and pirated content.
If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
How to remove malware manually?
Most trojan infections can be removed by running a full system scan with Combo Cleaner. The full manual procedure below is for cases where automatic removal failed, where you want to verify a scan caught everything, or where the threat has multiple persistence points.
Disconnect from the network
Unplug your Ethernet cable and turn off Wi-Fi. If you're on a laptop, the airplane-mode key works fastest.
Many trojans exfiltrate data - saved browser passwords, banking sessions, screenshots - and accept remote commands. Cutting the network stops both immediately. Keep it disconnected until Phase 4.
Boot into Safe Mode with Networking
Safe Mode loads a minimal set of drivers and stops most malware from auto-running. "With Networking" lets you download tools - re-enable Wi-Fi only after you've booted in.
Open . Click Restart now next to Advanced startup.
Your computer will restart into the "Choose an option" menu. Click . After the second reboot, press 5 or F5.
Click the Windows logo, hold Shift, click the Power icon and choose Restart. In the Choose an option screen, click . Press F5.
Windows 8
Go to the Start Screen, type Advanced, select Settings → Advanced startup options → Restart now → Troubleshoot → Advanced options → Startup settings → Restart → F5.
Note: Windows 8 reached end-of-life in January 2023 - running on it puts you at much higher risk of reinfection.
Windows 7
Click Start → Shut Down → Restart → OK. As the system boots, press F8 repeatedly until the Windows Advanced Options menu appears, then choose Safe Mode with Networking.
Note: Windows 7 reached end-of-life in January 2020 - running on it puts you at much higher risk of reinfection.
Inspect running processes with Process Explorer
Download Process Explorer from Microsoft Sysinternals. Run it as Administrator. Click and .
Sort by "Verified Signer." Anything unsigned running from %AppData%, %LocalAppData%, %Temp%, or %ProgramData% is suspicious. Right-click → Properties to see the full image path. Right-click → "Search Online" to look up unfamiliar process names.
Task Manager hides full file paths, doesn't show digital signatures, and groups processes in ways that make malware easy to miss. Process Explorer is the same tool Microsoft engineers use.
Map every persistence point with Autoruns
Download Autoruns. Right-click Autoruns.exe and choose Run as administrator - without elevation, Autoruns can't inspect protected registry hives.
In the menu, open and , then click Refresh.
Modern trojans don't just live in startup. Walk through these tabs and look for unsigned or unfamiliar entries:
- Logon - classic Run/RunOnce keys
- Scheduled Tasks - frequent hiding spot, especially tasks with PowerShell, MSHTA, or rundll32 actions
- Services - unsigned services in non-Microsoft folders
- WMI - Event Subscriptions are a stealthy persistence mechanism (MITRE T1546.003)
- Image Hijacks - Image File Execution Options "Debugger" abuse
- AppInit - DLLs loaded into every GUI process
- Browser plug-ins - unsigned add-ons across all installed browsers
Right-click any suspicious entry → "Jump to Image" to see the actual file. Right-click → "Search Online" opens VirusTotal for the file hash. Don't delete yet - just write down the file paths and entry names. We'll remove them after the scans.
Check the hosts file and DNS settings
Trojans often redirect bank, antivirus, and update domains to attacker-controlled servers by editing the hosts file or DNS settings.
Hosts file: Open Notepad as Administrator and open C:\Windows\System32\drivers\etc\hosts. Legitimate entries are commented with #. Any uncommented IP-to-domain mapping is suspicious - especially redirects for microsoft.com, windowsupdate, or your bank.
DNS settings: Open Command Prompt as Administrator and run ipconfig /all. Confirm your DNS servers point to your ISP, your router, or a known public resolver (Cloudflare 1.1.1.1, Google 8.8.8.8). Then open and verify both DNS and DNS over HTTPS (DoH) settings haven't been hijacked.
A clean PC with hijacked DNS is still a compromised PC. You'll think you're at chase.com and you'll be at the attacker's clone.
No single antivirus catches everything. The order below is intentional: offline scan first (catches rootkits before Windows fully loads), then on-demand scanners on the running system, then manual cleanup of anything they missed.
Run Microsoft Defender Offline
Reboot to normal Windows. Open . Select Microsoft Defender Antivirus (offline scan) and click Scan now. Your computer will restart into a stripped-down environment and scan before the full operating system loads.
Rootkits and bootkits hide from any scanner running on the same Windows session that's already infected. A pre-boot offline scan sees the disk before the malware can hide itself.
VB100 certified. Includes anti-trojan, registry/persistence scanning, anti-spyware in one pass. The 7-day free trial is available.
Download Combo CleanerRun Combo Cleaner full system scan
Install Combo Cleaner and run a full system scan (not the quick scan). Let it complete fully, review the detected threats, and apply the recommended actions. Combo Cleaner will quarantine known trojans and registry persistence.
Run Microsoft Safety Scanner as a second-opinion scan
Download Microsoft Safety Scanner (MSERT.exe), Microsoft's free on-demand tool. The binary expires every 10 days, which means every download has the latest signatures. Run a full scan after Combo Cleaner to catch anything one engine alone might miss.
Different scanning engines catch different threats. Running an additional Microsoft scan after Combo Cleaner is the single most underused verification step in malware removal.
Manually remove anything still listed in Autoruns
Reopen Autoruns. Anything you flagged in Step 4 that's still present hasn't been caught by the automated scans. For each remaining suspicious entry: right-click → Delete in Autoruns (this removes the persistence registration), then navigate to the file path and delete the actual file. Empty the Recycle Bin.
Some malware files reappear after deletion because something else on the system recreates them. If you delete a file and it returns within minutes, you have a remaining persistence point that Autoruns didn't show - usually a service or scheduled task running under SYSTEM. Re-run the scans from Steps 6-8 or proceed to a clean install (see end of guide).
Reset browsers and clear notification permissions
Trojans and adware frequently hijack browsers - change the default search engine, install rogue extensions, or grant themselves notification permissions to keep displaying scam pop-ups even after the malware is gone.
- Chrome: visit
chrome://settings/resetand click "Restore settings to their original defaults." Then visitchrome://settings/content/notificationsand remove any unfamiliar sites. - Edge: visit
edge://settings/reset. Then checkedge://settings/content/notifications. - Firefox: open
about:supportand click Refresh Firefox (Firefox uses "Refresh," not "Reset"). Then check Settings → Privacy & Security → Permissions → Notifications.
Review installed extensions in each browser and remove anything you don't recognize, especially extensions you didn't install yourself.
Re-enable Defender, Tamper Protection, and update everything
Many trojans disable security software. Open and confirm Real-time protection, Cloud-delivered protection, and Tamper Protection are all turned on. Tamper Protection prevents malware from disabling Defender silently.
Then run Windows Update () and update your browsers and applications. The infection vector that let the trojan in originally usually involves outdated software.
Change passwords from a clean device
If the trojan was an info-stealer (Lumma, RedLine, Vidar, and similar are extremely common), assume every password saved in your browser is compromised. Change them from a different, known-clean device - your phone is fine if it's not infected.
Recommended order:
- Primary email first - it's the recovery hub for everything else
- Banking and financial accounts
- Password manager master password (if you use one)
- Social media, shopping, and remaining accounts
Where available, enable phishing-resistant multi-factor authentication (passkeys / FIDO2 hardware keys / authenticator apps) - SMS-based MFA is bypassable by sophisticated attackers.
Verify the clean and monitor for 7 days
Reconnect to the network and run one final full scan with Combo Cleaner. Open Task Manager (Ctrl + Shift + Esc) and switch to the Startup apps tab - confirm nothing suspicious has reappeared.
Over the next 7 days, watch for symptom recurrence: unexpected high CPU usage, unknown processes returning, browser redirects, or pop-ups. If anything returns, you missed a persistence point and the procedure needs to be repeated - or you may have a deeper compromise that requires a clean install.
When to clean install Windows instead
Manual removal isn't always the right answer. Reinstalling Windows from scratch is the only way to be 100% certain when:
- The malware reappears after every removal attempt
- A bootkit or UEFI rootkit was detected (this class of threat sits below the operating system and survives a normal Windows reinstall)
- A confirmed credential-theft trojan ran with administrator privileges (Lumma, RedLine, Vidar) - the system likely has multiple unknown payloads
- The PC is used for online banking, business email, or anything where partial doubt isn't acceptable
A clean install is a 30-60 minute process: Windows 11 reinstall via . Back up documents to external storage first, scan the backup with Combo Cleaner before restoring it, and reinstall applications fresh - never restore them from a backup of the infected system.
Important: Manual removal requires advanced computer skills. If you're not confident identifying system files from malicious files, run an automated scan with Combo Cleaner and Windows Defender and stop there - that path catches the vast majority of consumer trojans without the risk of breaking Windows by deleting the wrong file.
