Get a message: This remote connection could harm your computer

 

 

“When I try to connect to a remote desktop, a message appears which says something like "This remote connection could harm your local or remote computer. Make sure that you trust the remote computer before you connect". Why would it harm my PC? I can understand that if I am sharing local resources or something like that, but if I am just connecting to a remote desktop how would that harm my computer? How can I remove the warning?”

- Question from  Stackexchange

This remote connection could harm your PC

Why would appear “This remote connection could harm your PC?”

Briefly, the warning is issued because there have been some very infamous RDP exploits of it in the past, such as vulnerability to attacks on non-encrypted connections. After describing the cause for the warning, let's look at the potential threats that the user may face.

  • User activity tracking and keylogging. In essence, an untrusted RDP remote server can record all your activities on the server, including the websites you browse, the files you download, the files you access, the passwords you enter when you access the remote service through the RDP server and essentially track your complete session, which may have a bad effect on your important data.
  • Client infection via remotely hosted files. Any files you download from the remote server that is hosting an RDP session may have been tampered with or infected with malware. You may erroneously believe any of these files and influence your work or something else.
  • Man-in-the-middle. Similar to user activity tracking, the attacker is active on the RDP server to which you connect and is listening in on your RDP client to the RDP server connection. Aside from being able to inspect the contents of exchanged network packets, a man-in-the-middle can also alter them. The RDP session can be secured using TLS, effectively prohibiting eavesdropping on it, however, this isn't always the case when connecting to other computers via the RDP server. Brief, the whole session of your remote connection is not private actually.
  • Hacking attacks. An attacker gains your trust and tricks you into entering an RDP server address that you think you can trust when establishing a new session, but the address you enter is actually the hacker's choice. The hacker can host an RDP server at this address for the sole purpose of recording your login credentials for another real RDP server that you intend to connect to.
