Imunify360 RapidScan: Feel the Need, the Need for Speed

The release of Imunify360 v4.3 brings RapidScan, a feature to improve scanning speeds by as much as 1000%. We're making anti-malware and antivirus scans faster with RapidScan , a new scanning option for Imunify360. Quicker scans mean lower system resource usage, and an opportunity to scan more frequently, further hardening your systems’ security posture. Here's a short summary of how we've managed to get these impressive performance increases. Faster File Integrity Checking – File metadata, such as file hashes, are now stored locally. This means that unchanged files don't need to be rescanned, and no need to schedule complete scans for quiet times of the day. Efficient Cloud-assi...

Introduction to Imunify Hooks

Hooks are a new addition to our flagship cybersecurity product Imunify360. In my recent post on hooks , I described how they let you capture events from the agent and act on them. For example, you might want to automatically notify a user or suspend a web hosting account if Imunify360 detects malware in the account’s file system. That last scenario is explained in a video presented by our Senior Sales Engineer, Jamie Charleston . He shows you the code and steps needed to set up an automated action based on malware detection. You can watch it here.

ClamAV Zip Bomb Makes CPUs Choke

A new vulnerability has been discovered [1] in the popular ClamAV antivirus scanning engine. ClamAV is one of the antivirus scanning engines used in ImunifyAV and Imunify360. For this reason, we’ve released an update of the ClamAV package so that ImunifyAV and Imunify360 can be protected from this vulnerability. How it works The vulnerability means that certain kinds of highly-compressed zip files can’t be scanned. David Fifield [2], a security researcher, found that, using overlapping techniques, he could generate files with extraordinary compression ratios. In one case, he managed to compress a 281 TB file down to 10 Mb. That’s a compression ratio of more than 28,000...

How much freedom should a user have to configure their own settings?

Imunify360 lets you change a lot of settings and customizations in the admin UI. There are also some settings in the user UI too, so users can enable/disable Proactive Defense, or choose the default action when malware is detected. Some of those settings, under certain circumstances, can affect server security. So today’s question is a little trickier than usual...
