Move to new new server after hack

Postby protelit » Fri May 24, 2019 3:47 pm

Last week we got hit with the dblaunchs hack.
I was not able to trace down right where they installed it so I made a cron job to pkill it if running every 2 minutes to buy me some time. I get with our users and was having them clean up their mail boxes to make a fix faster.
Well today the hackers are at it again with new toys. I have no log files, AV is disabled, and other "fun" stuff. This server is very old, running Ubuntu 12.04 with Zimbra version 8.7.1_GA. So my thought is to just spin up a new server this time as a virtual. My issue is saving as much as possible. I a ASSuME the only way to do this is to make a new server with Ubuntu 16.04 and install 8.7.11 and then import the users and messages some how, then upgrade to 8.8.12

My questions,
1) I am assuming it will not do much good installing the 8.7.11 patch after the fact, but is it possible that would restore the log files so I could have a chance finding what and where the .sh file is?
2) What is the best practices for exporting and importing everything ? I looked at Zextras Migrate and it looks good, is it?
3) What protection is best to protect against this again?

Install the latest version of ZCS on a new server then use the ZeXtras Migration Tool to move everything to a new server and, yes, it really is that good. If you're behind a firewall or nat router then I'd suggest you b lock off internet access (inbound and outbound) to the old server while you do the move.

Thanks, Mr. Phonix for your directions.
I'm using Network Zimbra 8.6 edition.
I install a new Zimbra server 8.8.12 network edition ...for migration testing using Zextras tool.
Can I use the current license file used in Zimbra 8.6 for Zimbra 8.8.12?? I upload the same file ..but need activate.
If I activate it, What will happen for the old system?

nothing for your old server. It dose not deactivate your license on your old server.
