Vmware - Certificate renew and Hostname or IP has changed. Regenerating the self-signed certificates.

I was not able to connect to vCenter Server Appliance, so I restarted it.

 After that it showed that it will be renewed ssl certificates because VCSA wasn´t restarted for a long period (more than one year in this case).

Later in console I got stuck on:

Hostname or IP has changed. Regenerating the self-signed certificates.
Starting VMware vPostgres: ok
Waiting for the embedded database to start up: .[OK]

Issue was solved using this article:

Veeam - B&R 7/8/9 stopped to work when renamed server name how to solve

With Veeam 7/8/9 B&R stop to work if you rename server.

To restore functionality you need to change and analyze these register fields putting new server name.

 I suggest to eviscerate every single key, could you have more subfolder than in my case

HKLM\SOFTWARE\
Veeam\Veeam Backup and Replication\SqlServerName
Veeam\Veeam Backup Catalog\CatalogSharedFolderPath

HKLM\SOFTWARE\Wow6432Node
\Veeam\Veeam Backup and Replication\SqlServerName
\Veeam\Veeam Backup Catalog\CatalogSharedFolderPath
\Veeam\Veeam Backup Packages\{06C5CCDE-FB93-4566-A13F-75C8A2AFABDC}\{564d7967-2024-de0e-f087-bc2e39fba624}\name

It's important that you will change registry keys that are related to sql istances:

 \\HKLM\Software\VeeaM\Veeam Backup Catalog\SqlServerName (Should be local)
\\HKLM\Software\VeeaM\Veeam Backup Reporting\SqlServerName (Should be local)

From this article I proceed to highlight main activities to mitigate Cryptlocker. 

 More details on original italian article.

 http://www.devadmin.it/2016/02/15/crypto-ransomware-mitigations/

<------->

 Considering that this kind of virus can not be solved with normal AV definition here they are some mitigation approaches:

 1. Using a product like Sophos UTM (Unified threat management)

2. Proceed to block these files extension going over extension itself but analyzing file header too (this task should be done from antispam provider/tools)

  • Applications Files: *.exe, *.lnk, *.pif, *.dll, *.ocx, *.sys, *.scr, *.msi, *.msp, *.gadget, *.application, *.com, *.hta, *.html, *.htm, *.jar, *.cpl, *.msc, *.hlp
  • File VBScript e JavaScript: *.vb, *.vbs, *.vbe, *.js, *.jse
  • File script Monhad (rinominato poi in ProwerShell): *.msh, *.msh1, *.msh2, *.mshxml, *.msh1xml, *.msh2xml
  • File script PowerShell: *.ps1, *.ps1xml, *.ps2, *.ps2xml, *.psc1, *.psc2
  • File script DOS: *.bat, *.cmd
  • File Windows Script: *.ws, *.wsf, *.wsc, *.wsh
  • File di collegamento e configurazione: *.lnk, *.pif, *.sfc, *.inf, *.reg
  • *.zip, *.rar, *.7z.

3. With outlook you could filter precedents attachment extentions using these articles:

4. Turnoff hyperlink inside Outlook


5. Block application running inside user profile (could create problems)

 You can utilize this article to create suitable GPO to prevent this kind of problem:

6. Enabling File extension view creating a GPO for that

Alternatively using Folder Options Extension


7. Using The Enhanced Mitigation Experience Toolkit a Microsoft tool that was created against Zero Day vulnerabilities.

8 . Verifying that each user has minimal permissions on pc/shares to maximum reduce attack surface utilizing these tools too:

9.  Enabling server auditing on shares and files to quickly identify infection location searching for technet Microsoft article, otherwise there is this script
