What is the best way to detect malware?
The best option, especially for larger organizations, is to employ an intrusion detection system, which can be host-based or network-based. Host-based intrusion detection systems (HIDSs), which are installed on a specific device, monitor log files and application data for signs of malicious activity; network-based intrusion detection systems (NIDSs), on the other hand, track network traffic in real time, on the lookout for suspicious behavior. When used together, HIDSs and NIDSs create a security information and event management (SIEM) system. SIEM is an incredibly beneficial part of a strong security regimen and can help to block software intrusions which have slipped past firewalls, antivirus software, and other security countermeasures.

RATs have the same remote-control functionality as RDPs, but are used for malicious purposes. Attackers always code software to avoid detection, but attackers who use a RAT risk being caught when the user is in front of the device and the mouse moves across the screen. Therefore, RAT authors must create a hidden program and use it when the user is not in front of the device. To avoid detection, a RAT author will hide the program from view in Task Manager, a Windows tool that lists all the programs and processes running in memory. Attackers aim to stay hidden from detection because it gives them more time to extract data and explore network resources for critical components that could be used in future attacks.

Vendors for these programs publish updates frequently as new malware is found in the wild.
What is remote control software?
Legitimate remote-control software exists to enable an administrator to control a device remotely.
