Organizations have moved business-critical apps to the cloud and attackers have followed. 2020 was a tipping point; the first year where we saw more cloud asset breaches and incidents than on-premises ones. We know bad actors are out there; if you’re operating in the cloud, how are you detecting threats? Cloud is different. Services are no longer confined in a single place with one way in or one way out.
Right on the heels of CVE-2022-4092, another local privilege escalation flaw in the Linux Kernel was disclosed on Monday, nicknamed “Dirty Pipe” by the discoverer. MITRE has designated this as CVE-2022-0847. Similar to the “Dirty COW” exploit (CVE-2016-5195), this flaw abuses how the Kernel manages pages in pipes and impacts the latest versions of Linux.
The most beautiful and inspiring aspect about open source code is, well, that it’s open source. We can look at open source packages like gifts that are exchanged between developers across the engineering world, allowing them to learn from the work other people do, contribute their own expertise, and grow their professional capabilities. Contributing to open source is much appreciated, and it is important to remember not only to benefit from these projects, but also to contribute back.
Kubernetes is a valuable resource and a leading container management system in development pipelines across the world, but it’s not exempt from malicious attacks. Using Kubernetes requires a deep understanding of Kubernetes’ environment—including the different vulnerabilities you can be exposed to while creating, deploying, or running applications in your clusters.
Linux maintainers disclosed a privilege escalation vulnerability in the Linux Kernel. The vulnerability has been issued a Common Vulnerability and Exposures ID of CVE-2022-0492 and is rated as a High (7.0) severity. The flaw occurs in cgroups permitting an attacker to escape container environments, and elevate privileges. The vulnerable code was found in the Linux Kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function.
In the last few years, Kubernetes has grown exponentially in popularity. Its wide adoption can be attributed to its open source nature, flexibility, and ability to run anywhere. Developers also love the fact that you can manage everything in Kubernetes using code. kubectl is the Kubernetes-specific command line tool that lets you communicate and control Kubernetes clusters. Whether you’re creating, managing, or deleting resources on your Kubernetes platform, kubectl is an essential tool.
We’re excited to announce that infrastructure as code (IaC) and container security are joining code and open source dependency security in the free Snyk plugin for JetBrains IDEs. As of today, developers using JetBrains IDEs can secure their entire application with a click of a button. Snyk Security for JetBrains increases code security and reduces time spent on manual code reviews by empowering developers to find and fix issues within their JetBrains IDEs.
Malicious Docker containers are a relatively new form of attack, taking advantage of an exposed Docker API or vulnerable host to do their evil plotting. In this article, we will walk through the triage of a malicious image containing a previously undetected-in-VirusTotal (at the time of this writing) piece of malware! Leaving a Docker API endpoint exposed to the world can have a variety of negative consequences.
The rise of cloud native and containerization, along with the automation of the CI/CD pipeline, introduced fundamental changes to existing application development, deployment, and security paradigms. Because cloud native is so different from traditional architectures, both in how workloads are developed and how they need to be secured, there is a need to rethink our approach to security in these environments.
