Current release info

Version: 4.2.7

Rolled out to: 5%

Last updated: August 8, 2019 11am EST



  • Starting from v4.2, Imunify360 supports ‘hooks’. This is a script-based interface for various application events, such as “malware-detected”, “malware-scanning”, “agent”, etc. This is a simple and effective way to automate Imunify360 alerts and event processing. For example, an administrator can have Imunify360 call a script when malicious files are detected or misconfigurations are detected.

Malware Scanner

  • We have added new settings to limit the resource impact of malware scanning.

    IM360 420 3

  • We have introduced a new setting, disable_user_ignore_list, that lets you hide the Ignore List tab for end users.
  • The scanning engine has been enhanced with a new de-obfuscator and decryptor for encoded files.


  • Statistics (number of incidents) are now correct in titles.

    IM360 420 4

  • Notifications about server security and Imunify360 configuration are shown, along with recommendations for making server security effective and proactive.

Reputation Management

  • The list of vendors was expanded and the verdict list enhanced.

    IM360 420 7

Proactive Defense

  • Performance is improved, and the scanning of malicious PHP has been optimized by using precompiled signatures.
  • Event recording in the Blamer is improved, and new/de-duped events are not recorded.


  • SSL processing is faster.


  • We added a new option, “Manage CSF Events and Lists“, to enable/disable the integration between CSF and Imunify360.

    IM360 420 8


  • The support menu item can be hidden via settings (to be used by resellers of Imunify360, for example).


  • Added OSSEC “Active Response” setting.

    IM360 420 9

  • Enhanced Imunify360 installation process, added slides with feature descriptions while the extension is deploying.
  • Newsfeed imports all recent news from the blog.
  • Updated translation of the UI.
  • “Lists” item renamed to “Firewall” in the menu.

Bug Fixes

  • Proactive Defence: Move from zzzzzzz-pecl.ini back to alt-phpXX php.ini (bug)
  • Proactive Defence: freezes PHP if Imunify360 config file is broken (bug).
  • Fixed rare cases where the agent hangs on startup when integrated with CSF.
  • Malware Scanner: We now cancel background scanning once settings are updated.
  • UI fixes: Fixed the “Restore” link in the quarantine popup, and fixed the charts description in the Dashboard.
