Public Travis CI Logs (Still) Expose Users to Cyber Attacks

In our latest research, we at Team Nautilus found that tens of thousands of user tokens are exposed via the Travis CI API, which allows anyone to access historical clear-text logs. More than 770 million logs of free tier users are available, from which you can easily extract tokens, secrets, and other credentials associated with …

Aqua Nautilus Discovers Redigo — New Redis Backdoor Malware

Aqua Nautilus discovered new Go-based malware that targets Redis servers. The attack was executed against one of our deliberately vulnerable Redis honeypots (CVE-2022-0543). Our investigation revealed new undetected malware written in Golang designed to target Redis servers to allow the attacking server to dominate the compromised machine. Therefore, the malware received the name Redigo. In …

Threat Alert: Anatomy of Silentbob’s Cloud Attack

Aqua Nautilus researchers identified an infrastructure of a potentially massive campaign against cloud native environments. This infrastructure is in early stages of testing and deployment, and is mainly consistent of an aggressive cloud worm, designed to deploy on exposed JupyterLab and Docker APIs in order to deploy Tsunami malware, cloud credentials hijack, resource hijack and …

TeamTNT Reemerged with New Aggressive Cloud Campaign

In part one of this two-part blog series, titled The Anatomy of Silentbob’s Cloud Attack we provided an overview of the preliminary stages of an aggressive botnet campaign that aimed at cloud native environments. This post will dive into the full extent of the campaign and provide a more comprehensive exploration of an extensive botnet …

Three Years Later: The Meow Campaign Reaches Jupyter

In 2017 and 2020 we saw the oddest campaign – ‘Meow’ – targeting unsecured databases such as MongoDB, Elasticsearch, Cassandra, CouchDB, and other software such as Hadoop clusters, FTPs, Jenkins etc. The Modus Operandi was very simple finding an exposed instance, deleting everything, and destroying data without any explanation. Back in 2017 and 2020, it …

TrailShark: Understanding AWS API and Service Interactions

In this blog, we introduce TrailShark, a plugin that connects Wireshark with AWS CloudTrail logs. This open-source tool was developed as part of the “Bucket Monopoly” research, during which we identified six vulnerabilities in AWS by tracking service interactions and internal API calls. These vulnerabilities range from remote code execution (RCE) and full-service user takeover …

Bucket Monopoly: Breaching AWS Accounts Through Shadow Resources

During February 2024, we discovered critical vulnerabilities in six AWS services. The impact of these vulnerabilities range between remote code execution (RCE), full-service user takeover (which might provide powerful administrative access), manipulation of AI modules, exposing sensitive data, data exfiltration and denial of service.

AWS CDK Risk: Exploiting a Missing S3 Bucket Allowed Account Takeover

In June 2024, we uncovered a security issue related to the AWS Cloud Development Kit (CDK), an open-source project. This discovery adds to the six other vulnerabilities we discovered within AWS services. The impact of this issue could, in certain scenarios (outlined in the blog), allow an attacker to gain administrative access to a target AWS account, …

Shadow Roles: AWS Defaults Can Open the Door to Service Takeover

What if the biggest risk to your cloud environment wasn’t a misconfiguration you made, but one baked into the defaults? Our research uncovered security concerns in the deployment of resources within a few AWS services, specifically in the default AWS service roles. These roles, often created automatically or recommended during setup, grant overly broad permissions, …
