Cado Security uncovers sophisticated Linux malware campaign

Cado Security Labs researchers have detected an emergent Linux malware campaign aimed at misconfigured servers running Apache Hadoop YARN, Docker, Confluence, and Redis web-facing services. The firm disclosed its findings on Wednesday, 6 March. This unusual and as yet unreported campaign deploys unique payloads, comprising four Golang binaries that automate the discovery and infection process of hosts operating these services.

The sophistication and breadth of this cyber assault demonstrate the range of initial access strategies at the disposal of cloud and Linux malware developers. By exploiting commonly found misconfigurations and an n-day vulnerability, the attackers use these tools to launch Remote Code Execution (RCE) attacks and infiltrate new hosts, extending the reach of their campaign. This strategy underscores the substantial investment attackers are making into comprehending the nature of the web-facing services typically deployed in cloud environments.

Indeed, keeping updated on the latest vulnerabilities and leveraging this understanding helps threat actors gain access to their intended targets. The rise of such comprehensive and technically advanced cyberattacks signals a need for businesses to strengthen their security measures, ensuring their systems are configured correctly and potential vulnerabilities are addressed promptly.

At the forefront of this discovery is Cado Security, a newly emerged player in the field, providing a pioneering cloud forensics and incident response platform. Cado's technology is designed to automate forensic-quality data capture and processing across various environments – including cloud, container, and serverless – presenting the data in a central console to facilitate investigation. The platform is activated within the organisations' existing detection or automation platform, ensuring immediate data capture following the detection of a security incident. This leads to security teams' swift investigation and response, reducing the potential impact of breaches.

The founders of Cado Security are ex-incident responders possessing extensive experience in tackling highly complex threats. The firm operates from offices in the UK and US and is quickly making its mark by uncovering emerging cyber threats and offering innovative solutions to tackle them. For instance, the detection of this Linux malware campaign is a testament to the exceptional threat research led by Matt Muir at Cado Security.

With the nature of cyber threats continuously evolving and attackers becoming increasingly familiar with the technologies deployed in cloud environments, it is crucial now, more than ever, that companies invest in capable and innovative cybersecurity solutions. Cado Security's disclosure represents a proactive approach in the relentless fight against cybercrime, while its pioneering platform could provide a formidable defence in this digital battlefield.
