Posible hacking causing unwanted mailbox redirections

Post by xtremesoft » Tue May 26, 2020 12:11 pm

First of all, apologies for my bad english.

Some of our post offices have experienced the appearance of unwanted mailbox redirections that the users have not created.
The destination of these readirections are usually non existent gmail accounts that we can see login in mailenable webmail application.

This usually happens on mail boxes of users whose machines have been infected by virus.
We think it could be related to some kind of programmatically hack using the stolen password of the user webmail, or maybe an undetected security hole.

Has anyone experienced a similar situation?

If client machines are infected with viruses (in particular key loggers) then the first step is to clean the client machines and ensure they run security software to prevent this. Although these scenarios are rare the most common cause of a spammer exploiting the mail server is by guessing simple passwords. Therefore it would be best practice to instruct your clients to set complex passwords. Also ensure that you are running the latest version of MailEnable Professional with all the latest security fixes.
