First Hypervisor Vulnerability Allowing Guest to Attack

This vulnerability is more historical rather than practical, but it caught attention of the Digital Edge security team as we think it is the first hypervisor vulnerability allowing a guest to attack hypervisor host

The virtualization idea is that virtual instances should be running in their own jail and would not be able to communicate with other virtual instances or the physical host itself. This isolation technique makes people confident going into the “cloud” as in theory that nobody can break the jail. Your “neighbors” cannot damage you. 

If the isolation concept fails, a criminal can purchase a virtual machine “next” to you and hack into your machine. Hypervisor software is doing everything to block visibility from one virtual instance to another or to the physical host. 

New vulnerability - CVE-2015-7835 was logged today simply stating: 

“The mod_l2_entry function in arch/x86/mm.c in Xen 3.4 through 4.6.x does not properly validate level 2 page table entries, which allows local PV guest administrators to gain privileges via a crafted superpage mapping.” 

What this actually means is that a hacker can purchase a VM and get control over its physical host and then over VMs running on that physical host. In our opinion it is the worst bug we have seen

October 11-17 – troubling week for the security

    Digital Edge is committed to providing the highest levels of security within all the IT infrastructure environments under its care. In order to achieve this utmost goal for all of our clients, we continuously maintain vigilance both on the productive side of IT as well as on its destructive side. We thus send out news and security bulletins such as this one from time to time to ensure that our clients are informed and educated on any important developments in IT security and are fully aware of what we are doing to ensure that we and our clients are always at the Cutting and at the Digital Edge of technology. 

    The week may be over but it was very troubling. There are a few events that attracted our attention so the Digital Edge security team wanted to provide our analysis and some suggestions how to stay secure. 

          1. Microsoft has released multiple patching addressing very critical security vulnerabilities. They include fixing for holes allowing user computer take over techniques through multiple attack vectors against Microsoft Office, VB and Java scripts, Windows Shell and Kernel itself. All those attacks can be delivered through phishing emails or through tricking users to open infected web sites. 

          2. At the same time, security agencies are reporting multiple instances of outbreak of Dridex malware outbreak. In short, the malware gets delivered to computers over the same mechanisms mentioned above through vulnerabilities that Microsoft addressed in this week’s patch but the malware concentrates on 3 things: 

                a. Stealing personal information 
                b. Stealing banking credentials to be able to transact on the infected user/computer behalf 
                c. Execute command-and-control (C2C). 

              Besides that, the infected computer can be employed for spam distribution and distributed denial of service (DDOS) attacks 

          3. On October 15, 2015, UltraDNS – large DNS service and content delivery provider went down for 90 minutes. Even though UltraDNS claims that the cause of the outage was an “internal issue in a server on East Coast” many security experts suggest that UltraDNS sustained serious DDOS attack.  

      All Digital Edge managed or co-managed clients will be patched according to individual schedules. 

      Besides that click here to make sure that you are safe and free of Dridex.

Free Advice For Priceless Security

Potential Threat: One of the techniques that hackers use to infiltrate operating systems is known as polymeric downloaders. These are viruses that could download other, more complex viruses, password stealers or remote controlled software. These downloaders typically access systems via emails or zip files. They can also get to your computer in tandem with other programs, mostly together with free game downloads or with illegal software. These downloaders can also traverse when connecting infected USB disks to your computer. Virus authors aim to trick you into executing these downloaders. These tricks could be sophisticated, which sometimes could confuse even sophisticated computer users into executing the underlying viruses and infecting their systems. A more complex infecting technique is called polymorphic downloaders or polymorphic viruses, which allows viruses to traverse undetected.

Digital Edge is committed to the highest of security standards and making sure that its constituents are likewise serious about security which is all about knowledge and behavior. Click here to read about some free techniques for detecting and fighting polymorphic downloaders.
