A security researcher has discovered a critical vulnerability in the latest version of Apple's OS X Yosemite  that could allow anyone to obtain unrestricted root user privileges with the help of code that fits in a tweet. The privilege-escalation vulnerability initially reported on Tuesday by German researcher Stefan Esser , could be exploited by to circumvent security protections and gain full control of Mac computers. The most worrying part is that this critical vulnerability is yet to be fixed by Apple in the latest release of its operating system. This could make it easier for hackers to surreptitiously infect Macs with rootkits and other types of persistent malware. Thanks to an environment variable DYLD_PRINT_TO_FILE Apple added to the code of OS X 10.10 Yosemite.

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

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.
