Since the release of CVE-2020-8554 on GitHub this past December, the vulnerability has received widespread attention from industry media and the cloud security community. This man-in-the-middle (MITM) vulnerability affects Kubernetes pods and underlying hosts, and all Kubernetes versions—including future releases—are vulnerable. Despite this, there is currently no patch for the issue.

In April 2020, MalwareHunterTeam found a number of suspicious files in an open directory and posted about them in a series of tweets. Trend Micro later confirmed that these files were part of the first cryptojacking malware by TeamTNT, a cybercrime group that specializes in attacking the cloud—typically using a malicious Docker image—and has proven itself to be both resourceful and creative.

The use of honeypots in an IT network is a well-known technique to detect bad actors within your network and gain insight into what they are doing. By exposing simulated or intentionally vulnerable applications in your network and monitoring for access, they act as a canary to notify the blue team of the intrusion and stall the attacker’s progress from reaching actual sensitive applications and data.

Tigera, in collaboration with Microsoft, is thrilled to announce the public preview of Calico for Windows on Azure Kubernetes Service (AKS). While Calico has been available for self-managed Kubernetes workloads on Azure since 2018, many organizations are migrating their .NET and Windows workloads to the managed Kubernetes environment offered by AKS.

We are excited to introduce Calico Cloud, a pay-as-you-go SaaS platform for Kubernetes security and observability. With Calico Cloud, users only pay for services consumed and are billed monthly, getting immediate value without upfront investment.

Kubernetes provides abstraction and simplicity with a declarative model to program complex deployments. However, this abstraction and simplicity create complexity when debugging microservices in this abstract layer. The following four vectors make it challenging to troubleshoot microservices.
