At Elastic we are constantly innovating and releasing new features. As we release new features we are also working to make sure that they are tested, solid, and reliable — and sometimes we do find bugs or other issues. While testing a new feature we discovered a Linux kernel bug affecting SSD disks on certain Linux kernels. In this blog article we cover the story around the investigation and how it involved a great collaboration with two close partners, Google Cloud and Canonical.

The Australian Cyber Security Centre (ACSC) recently published an advisory outlining tactics, techniques and procedures (TTPs) used against multiple Australian businesses in a recent campaign by a state-based actor.

If you’ve worked with Elastic Support, you may have been asked to run the Support Diagnostic tool and provide the output in your support case. This is a common practice, but a lot of you out there may not know why. While the short answer is "it depends", this blog is going to explain why we keep asking for diagnostic files (as well as what’s in them). Simply put, the Support Diagnostic helps Elastic Support understand the state of your cluster.

Kubernetes has emerged the de facto container orchestration technology, and an integral technology in the cloud native movement. Cloud native brings speed, elasticity, and agility to software development, but also increases the complexity — with hundreds of microservices on thousands (or millions) of containers, running in ephemeral and disposable pods. Monitoring such a complex, distributed, transient system is challenging, and at the same time very critical.

How annoying is it when you get a telemarketing call from a random phone number? Even if you block it, it won’t make a difference because the next one will be from a brand new number. Cyber attackers employ the same dirty tricks. Using domain generated algorithms (DGAs), malware creators change the source of their command and control infrastructure, evading detection and frustrating security analysts trying to block their activity.
