Last week, TeamTNT launched a new campaign against Docker and Kubernetes environments. Using a collection of container images that are hosted in Docker Hub, the attackers are targeting misconfigured docker daemons, Kubeflow dashboards, and Weave Scope, exploiting these environments in order to steal cloud credentials, open backdoors, mine cryptocurrency, and launch a worm that is …

A new severe vulnerability was found in Unix and Linux operating systems that allows an unprivileged user to exploit this vulnerability using sudo, causing a heap overflow to elevate privileges to root without authentication, or even get listed in the sudoers file. In this blog, I’ll go over how this CVE can be exploited, what …

It has certainly been a rough year and just as life constantly evolves, so do cyber threats. So, here are a few blogs by our cyber security research group, Team Nautilus, that got the most attention from cloud native security professionals. These blogs highlight how attackers continue to get more creative over time, as we …

A year of challenges isn’t quite over yet, as a new vulnerability was found in containerd, CVE-2020-15257. When exploited, after providing a connection through the container to the host network, an attacker can gain root privileges on the host. This vulnerability was disclosed by Jeff Dileo of NCC Group, our investigation by Team Nautilus is …

Our cyber research team detected a new type of attack that executes and runs malware straight from memory in containers, thus evading common defenses and static scanning. This malware is using a rootkit to hide its running processes, then hijacks resources by executing a crypto miner from memory — leaving a backdoor that enables attackers …

Aqua’s Team Nautilus has uncovered a container image that, for the first time, allows bad actors to find and exploit vulnerabilities in Kubernetes clusters. The attackers propagate this malware through a Docker Hub lookalike account intended to dupe developers into downloading malicious images. To the best of our knowledge, this is the first known case …

A new vulnerability was found in containerd, located in the container image-pulling process. The new CVE includes manipulation of the image manifest, allowing attackers to craft an image that can leak the host’s registry or cloud credentials when pulled from a registry. This leak occurs even before the image is running any code on your …

Over the past few weeks, TeamTNT grabbed headlines after launching several novel attacks against cloud native infrastructure. In response, Docker Hub decided to remove TeamTNT’s malicious images from its community and deleted the user ‘Hildeteamtnt.’ But just a few days later, TeamTNT reemerged with a catchy logo “Still alive” embedded in their scripts (although “still …

Aqua’s Team Nautilus detected an impressive campaign that set out to hijack resources to enable cryptocurrency mining. This operation focused on several SaaS software development environments, including Docker Hub, GitHub, Travis CI, and Circle CI, by abusing their automated build processes.

Ever notice how news about hidden malware almost always focuses on remediation AFTER the fact? So did we. Even now, there’s yet another news story about a rash of attacks by a group called TeamTNT. They used a crypto-mining worm to steal AWS credentials from Docker Hub. Well, if hijacking cloud resources is so popular, …

We have some exciting news about two new features in Tracee, Aqua’s open source container and system tracing utility. Now, Tracee is much more than just a system call tracer, it’s a powerful tool that can be used to perform forensic investigations and dynamic analysis of binaries – both are incredibly useful when looking for hidden malware. Tracee can provide users with timely insights that previously required special knowledge and tools.

We at Team Nautilus – Aqua’s cyber security research team – discovered a new type of attack against container infrastructure. The attacker exploits a misconfigured Docker API port in order to build and run a malicious container image on the host. As far as we know, this is the first time that an attack in …
