NetSupport RAT is a remote access trojan that gives an attacker interactive control over a victim’s device after infection. Although it may be sold as legitimate remote administration software, criminals abuse it as malware to view the screen, run commands, move files, and maintain persistent access.
It matters because remote access malware often turns a single successful phishing or social-engineering step into full machine compromise. In real attack chains, NetSupport RAT is commonly delivered through fake verification pages, malicious scripts, or downloaded payloads hidden inside apparently harmless files. Once the user executes the attacker’s instructions, tools like PowerShell or a launcher script can retrieve and start the RAT without needing a traditional exploit.
Defenders look for suspicious child processes, unusual network beacons, and remote-control behavior on endpoints. Blocking script abuse, restricting PowerShell, and training users to distrust copy-paste instructions or branded prompts can reduce the chance that NetSupport RAT is installed in the first place.
