Posted: Sat May 20, 2017 8:51 am
Hello everyone,
my server problem exploits "brute force attack"
Hello everyone, I have been the victim of an attack on my server, my server does not publish the 7073 port, the attack seems to originate from the same server, i changed the password but there are continuous attempts to login. The server has been upgraded from zimbra 8.0.7 to the latest releases 8.7.7 and patches. I report under the log, please help me!!
