Cybercriminals Are Using Legit Cloud Monitoring Tools As Backdoor

Cybercriminals Are Using Legit Cloud Monitoring Tools As Backdoor
September 09, 2020Ravie Lakshmanan
A cybercrime group that has previously struck Docker and Kubernetes cloud environments has evolved to repurpose genuine cloud monitoring tools as a backdoor to carry out malicious attacks, according to new research. "To our knowledge, this is the first time attackers have been caught using legitimate third party software to target cloud infrastructure," Israeli cybersecurity firm Intezer said in a Tuesday analysis. Using software called Weave Scope , which is used as a visualization and monitoring tool for Docker and Kubernetes services, the TeamTNT threat actor not only mapped the cloud environment of their victims but also executed system commands without having to deploy malicious code on the target server explicitly. TeamTNT has been active at least since late April this year, directing their attacks on misconfigured Docker ports to install a cryptocurrency mining malware and a Distributed Denial-of-Service (DDoS) bot. Then last month , the crypto-mining gan

Undetectable Linux Malware Targeting Docker Servers With Exposed APIs

Undetectable Linux Malware Targeting Docker Servers With Exposed APIs
July 28, 2020Swati Khandelwal
Cybersecurity researchers today uncovered a completely undetectable Linux malware that exploits undocumented techniques to stay under the radar and targets publicly accessible Docker servers hosted with popular cloud platforms, including AWS, Azure, and Alibaba Cloud. Docker is a popular platform-as-a-service (PaaS) solution for Linux and Windows designed to make it easier for developers to create, test, and run their applications in a loosely isolated environment called a container. According to the latest research Intezer shared with The Hacker News, an ongoing Ngrok mining botnet campaign scanning the Internet for misconfigured Docker API endpoints and has already infected many vulnerable servers with new malware. While the Ngrok mining botnet is active for the past two years, the new campaign is primarily focused on taking control over misconfigured Docker servers and exploiting them to set up malicious containers with cryptominers running on the victims' infrastructu

Docker Images Containing Cryptojacking Malware Distributed via Docker Hub

Docker Images Containing Cryptojacking Malware Distributed via Docker Hub
June 25, 2020Ravie Lakshmanan
With Docker gaining popularity as a service to package and deploy software applications, malicious actors are taking advantage of the opportunity to target exposed API endpoints and craft malware-infested images to facilitate distributed denial-of-service (DDoS) attacks and mine cryptocurrencies. According to a report published by Palo Alto Networks' Unit 42 threat intelligence team, the purpose of these Docker images is to generate funds by deploying a cryptocurrency miner using Docker containers and leveraging the Docker Hub repository to distribute these images. "Docker containers provide a convenient way for packaging software, which is evident by its increasing adoption rate," Unit 42 researchers said . "This, combined with coin mining, makes it easy for a malicious actor to distribute their images to any machine that supports Docker and instantly starts using its compute resources towards cryptojacking." Docker is a well-known platform-as-a-servic

Docker Hub Suffers a Data Breach, Asks Users to Reset Password

Docker Hub Suffers a Data Breach, Asks Users to Reset Password
April 27, 2019Wang Wei
Docker Hub, one of the largest cloud-based library of Docker container images, has suffered a data breach after an unknown attacker gained access to the company's single Hub database. Docker Hub is an online repository service where users and partners can create, test, store and distribute Docker container images, both publicly and privately. The breach reportedly exposed sensitive information for nearly 190,000 Hub users (that's less than 5 percent of total users), including usernames and hashed passwords for a small percentage of the affected users, as well as Github and Bitbucket tokens for Docker repositories. Docker Hub started notifying affected users via emails informing them about the security incident and asking them to change their passwords for Docker Hub, as well as any online account using the same password. "On Thursday, April 25th, 2019, we discovered unauthorized access to a single Hub database storing a subset of non-financial user data. Upon

RunC Flaw Lets Attackers Escape Linux Containers to Gain Root on Hosts

RunC Flaw Lets Attackers Escape Linux Containers to Gain Root on Hosts
February 12, 2019Mohit Kumar
A serious security vulnerability has been discovered in the core runC container code that affects several open-source container management systems, potentially allowing attackers to escape Linux container and obtain unauthorized, root-level access to the host operating system. The vulnerability, identified as  CVE-2019-5736 , was discovered by open source security researchers Adam Iwaniuk and Borys Popławski and publicly disclosed by Aleksa Sarai, a senior software engineer and runC maintainer at SUSE Linux GmbH on Monday. The flaw resides in runC—a lightweight low-level command-line tool for spawning and running containers, an operating-system-level virtualization method for running multiple isolated systems on a host using a single kernel. Originally created by Docker, runC is the default container run-time for Docker, Kubernetes, ContainerD, CRI-O, and other container-dependent programs, and is widely being used by major cloud hosting and server providers. runC Containe

Microsoft Issues Emergency Patch For Critical Flaw In Windows Containers

Microsoft Issues Emergency Patch For Critical Flaw In Windows Containers
May 03, 2018Swati Khandelwal
Just a few days prior to its monthly patch release, Microsoft released an emergency patch for a critical vulnerability in the Windows Host Compute Service Shim (hcsshim) library that could allow remote attackers to run malicious code on Windows computers. Windows Host Compute Service Shim (hcsshim) is an open source library that helps "Docker for Windows" execute Windows Server containers using a low-level container management API in Hyper-V. Discovered by Swiss developer and security researcher Michael Hanselmann , the critical vulnerability (tracked as CVE-2018-8115) is the result of the failure of the hcsshim library to properly validate input when importing a Docker container image. This, in turn, allows an attacker to remotely execute arbitrary code on the Windows host operating system, eventually letting the attacker create, remove, and replace files on the target host. As Hanselmann explained  in his personal blog, "Importing a Docker container image or

New Release: Kali Linux for Docker — Deploy and Play!

New Release: Kali Linux for Docker — Deploy and Play!
May 27, 2015Mohit Kumar
The Developers of one of the most advanced open source operating system for penetration testing called ' KALI Linux ' have made the operating system available for Docker-addicted system administrators. But, What's Docker? Docker is a new open-source container technology, released in June 2014, that automates the deployment of applications inside self-sufficient software containers by providing an additional layer of abstraction and automation of operating-system-level visualization on Linux. Docker, built on top of Linux containers, is simply a way of managing multiple containers on a single machine. Nowadays, companies are adopting Docker at a remarkable rate. Docker is not just the favorite of Linux powers like RedHat and Canonical, but also big software firms, including Microsoft, which has embraced Docker. Why bringing Kali Linux for Docker? The same was happened to the developer of Offensive Security, who was requested for a Dockerised image of
