RDP is Microsoft’s proprietary protocol for enabling remote work across Windows servers. Many organizations use this popular remote access protocol. While RDP is very useful for enterprises, it has a large attack surface. 

With its wide use, it became a popular target for bad actors during the pandemic. Once enterprises made their RDP services available, cybercriminals took note. These bad actors used RDP to amplify their efforts. They also used malware to spot vulnerabilities. These vulnerabilities can open enterprises up to serious damage.

RDP must function with certain privileges to operate a machine for its user. Because of this, bad actors will inherit those privileges if they can get in.

Past vulnerabilities with RDP include BlueKeep and DejaBlue, which appeared in 2019. These allowed bad actors to bypass authorization and execute code on the server. Patches were created and made available.  But, these patches don’t prevent new vulnerabilities from happening. 

Patches are not always immediately available, either. This means that organizations should practice preparation and RDP security. This will help prevent attacks before they start.

Since RDP has become a target for cybercriminals, it’s unlikely that attacks will stop. More employees continue to work remotely. Enterprises need to practice awareness and adopt solutions to protect themselves from attacks. 

Solutions include consistent patching and placing RDP behind a secure gateway. Enterprises should also allow only the least privilege necessary. Employees should make sure to create complex passwords and enable 2-factor authentication. 

With these security measures in place, enterprises can reduce their risk of attacks. If organizations put in place these practices, RDP attacks may slow down.
