This is called a man-in-the-middle attack. This scenario is exactly what the “WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!” message is trying to warn you about. Of course, this isn’t always the case, and there are many reasons for the ECDSA key fingerprint to change for a server.
What should I do if my Remote Host Key has changed?
Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the RSA key sent by the remote host is 6e:45:f9:a8:af:38:3d:a1:a5:c7:76:1d:02:f8:77:00. Please contact your system administrator.
