A newly discovered zombie network that exclusively targets Apple computers running Mac OS X across the globe has compromised roughly 17,000 machines so far, giving hackers backdoor access to infected computers, researchers at Russian antivirus firm Dr.Web warned. According to a survey of traffic conducted in September by researchers at Dr. Web, over 17,000 Macs globally are part of the Mac.BackDoor.iWorm botnet , which creates a backdoor on machines running OS X. Researchers say almost a quarter of iWorm botnet are located in the US. The most interesting thing to notice about this botnet is that it uses a special method of spreading via a search service of Reddit posts to a Minecraft server list subreddit to collect the IP addresses for its command and control (CnC) network. The user who had posted that subreddit data has now been shut down though the malware creators are likely to form another server list. " It is worth mentioning that in order to acquire a control server add...

Cybersecurity isn't just another checkbox on your business agenda. It's a fundamental pillar of survival. As organizations increasingly migrate their operations to the cloud, understanding how to protect your digital assets becomes crucial.
