What is a Remote Access Trojan?
A Remote Access Trojan (RAT) is a type of malware that installs a hidden backdoor. Once inside, attackers can take over your system completely. Unlike other threats, RATs provide long-term access and often operate silently while attackers:
- Steal personal information such as banking details and passwords
- Access your webcam and microphone to spy on you
- Control your keyboard and mouse remotely
- Download, modify, or delete files on your system

How to Identify a RAT Infection
Since RATs hide in the background, spotting them early is tricky. However, you should be aware of these common symptoms:
- Slow performance, freezing, or random system crashes
- Unusual processes running in Task Manager
- Webcam indicator light turning on unexpectedly
- Antivirus alerts flagging suspicious behavior

How to Prevent RAT Infections
- Avoid opening attachments from unknown email senders
- Keep your operating system and apps updated
- Use a trusted antivirus program
- Enable two-factor authentication for accounts
- Download software only from verified platforms

How to Remove a RAT
- Disconnect your computer from the internet immediately
- Boot into Safe Mode
- Run a full scan using antivirus or anti-malware tools
- Use advanced removal programs such as Malwarebytes or HitmanPro
- If infection persists, consult a professional IT technician

Long-Term Protection Measures
- Enable real-time antivirus scanning and firewall protection
- Use a dedicated anti-malware tool
- Back up data regularly to cloud storage
- Educate yourself on social engineering tactics
