Why is RDP so common?
One of the reasons why RDP attacks are so common is because these services are relatively easy for hackers to target. You can see if RDP is running by looking for TCP port 3389, the default for almost all RDP versions. Since hackers understand that you’ll almost certainly use this port for RDP, they can place themselves there for an on-path attack.
Is RDP vulnerable?
Like most other programs, RDP is also open to vulnerabilities from unsafe user practices. Weak credentials are a particularly pressing concern, as many users reuse their device passwords for remote RDP logins. This password recycling could let cybercriminals access your system through credential stuffing or a brute-force attack.

The remote work environment is particularly appealing for attackers for several reasons. First, the home-network environment is not professionally managed. Most critically, this means that many more systems on home networks are not patched regularly, and a number of them are out of date with respect to vulnerability mitigation. Some may even be treated by their manufacturers as end-of-life (EOL) products, and will never receive mitigations even when serious vulnerabilities are found.

What is zero trust architecture?
In fact, the foundation of zero-trust architecture, an emerging trend in enterprise and distributed networking, is the idea that one's network should be assumed hostile. The key to securing the remote work environment is to extend these zero-trust assumptions further.

Why do VPNs run 24/7?
VPNs run 24/7, which means organizations are less likely to check for and apply security patches on a regular basis. This also makes VPNs vulnerable and susceptible to attacks by hackers. For instance, hackers may start a phishing campaign to target remote employees in order to steal their usernames and passwords that gives them access to the VPN, and by extension, your network.
Can malware be executed on a client?
The malware is then executed within the client — the victim’s device; the compromised device is left open to the hackers so they can access the private network directly. Hackers may also try to instill the use of macros within Excel or Word docs to execute malware and take over a PC.
