QEMU | Breaking Cybersecurity News | The Hacker News

Threat actors have been observed leveraging the  QEMU  open-source hardware emulator as tunneling software during a cyber attack targeting an unnamed "large company" to connect to their infrastructure. While a number of legitimate tunneling tools like Chisel, FRP, ligolo, ngrok, and Plink have been used by adversaries to their advantage, the development marks the first QEMU that has been used for this purpose. "We found that QEMU supported connections between virtual machines: the -netdev option creates network devices (backend) that can then connect to the virtual machines," Kaspersky researchers Grigory Sablin, Alexander Rodchenko, and Kirill Magaskin  said . "Each of the numerous network devices is defined by its type and supports extra options." In other words, the idea is to create a virtual network interface and a socket-type network interface, thereby allowing the virtual machine to communicate with any remote server.

Sysadmins know what the risks are of running unpatched services. Given the choice, and unlimited resources, most hardworking administrators will ensure that all systems and services are patched consistently. But things are rarely that simple. Technical resources are limited, and patching can often be more complicated than it appears at first glance. Worse, some services are so hidden in the background, that they just don't make it onto the list of things to be patched. QEMU is one of those services that tend to create difficulties with patching. It works away in the background and is easy to take for granted. Plus, patching QEMU involves significant technical and practical challenges – while requiring enormous resources. In this article, we'll address some of the difficulties around patching QEMU, and point to a solution that takes the toughest bits out of QEMU patching. Ignoring QEMU patching is a big risk You'll probably know about it if you're using QEMU – shor

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,
