Threat Actors Using release_agent Container Escape

Earlier this year, Aqua’s Team Nautilus detected a cryptocurrency mining campaign targeting our honeypots. As part of the campaign, the threat actors used a container escape technique that leverages the CGroup release_agent feature. This technique allows an attacker to break out from the container and compromise the host and, potentially, the entire network of an organization. …

Detecting and Capturing Kernel Modules with Tracee and eBPF

Security practitioners often need to investigate malicious artifacts in their environments, which can be challenging if those are deleted or loaded from memory. This is increasingly the case as threat actors are weaponizing Linux kernel modules to perform and hide their attacks. In this blog, we look into kernel modules and explain why they can …

Threat Alert: Cloud Network Bandwidth Now Stolen through Cryptojacking

Threat actors are looking to increase their financial gain and thus deploy cryptominers which are considered easy to use and lucrative. Cryptomining involves complex calculations leading to high computation power and consequently increased CPU consumption and electricity (or cloud) bill. Aqua Nautilus found a new type of cryptomining attack in the wild. As far as …

Detecting Drovorub’s File Operations Hooking with Tracee

Two years ago, the NSA (the United States’ National Security Agency) revealed that Drovorub, an advanced Russian malware created by the GRU 85th GTsSS team, had been discovered targeting Linux systems. Drovorub works by introducing advanced techniques which can manipulate the Linux operation system. It has an advanced kernel rootkit that hooks several kernel functions. In …

Threat Alert: New Malware in the Cloud By TeamTNT

Over the past week we observed three different attacks on our honeypots. The scripts and malware that were used bear a striking resemblance to none other than the threat actor TeamTNT. Eleven months ago they posted a farewell note on Twitter. Since then, we have only seen legacy attacks which automatically run on past infrastructure. …

HeadCrab: A Novel State-of-the-Art Redis Malware in a Global Campaign

Aqua Nautilus researchers discovered a new elusive and severe threat that has been infiltrating and residing on servers worldwide since early September 2021. Known as HeadCrab, this advanced threat actor utilizes a state-of-the-art, custom-made malware that is undetectable by agentless and traditional anti-virus solutions to compromise a large number of Redis servers. The HeadCrab botnet …

Cloud computing has revolutionized the way organizations design, develop, deploy, and manage their applications. While it has brought many benefits such as scalability, flexibility, and agility, it has also come with inherent complexities that have led to compromise …

Apache Applications Targeted by Stealthy Attacker

Researchers at Aqua Nautilus have uncovered a new attack targeting Apache Hadoop and Flink applications. This attack is particularly intriguing due to the attacker’s use of packers and rootkits to conceal the malware. The simplicity with which these techniques are employed presents a significant challenge to traditional security defenses.
