Also, recommended to limit outbound access. Limit inbound traffic to the application either by blocking the internet access completely or if the environment requires internet access, by using network rules or VPN to control inbound traffic.Ensure that Secure Socket Layer is used to protect data while transmitting.Use tokens or another authentication method to control access to the data development application.There are a few recommendations that can be followed to mitigate these risks and protect the data applications: – An intentionally compromised computer system that allows attackers to exploit vulnerabilities so the organization can study to improve their security policies. The attacker downloaded a nano binary to create the file cpt.py and execute the binary along with the cpt.py script.Ī honeypot is a security mechanism that creates a virtual trap to lure attackers. In this attack, Tracee detected two drift events, drooping and execution on the fly of a binary and a python file. To detect the malicious event there are number of runtime security detection engines. Tracee of Aqua Security continuously monitors their honeypots, which are open source runtime security and forensics tools for Linux designed to address common Linux security issues. The attack is simple and straightforward compared to ransomware that uses advanced techniques, such as Locky, Ryuk, WannaCry, or ransomware-as-a-service, such as GandCrab. It is possible that the adversary was experimenting with the attack on the machine, or the honeypot expired before the attack could be completed. The python file (cpt.py) was designed to delete itself after the execution to conceal the attack. It was stopped before further damage could be done.

In order to simulate a real-life enterprise environment, the honeypot included Jupyter notebooks as well as raw data files the attacker could encrypt.

Below is the kill chain of the attack:Ī misconfigured application allowed the attacker to connect to the server, download the libraries and tools (such as encryptors), and then manually create a ransomware script by pasting the Python code and executing it. A honeypot is setup with a Jupyter notebook application that exposed the attack on the internet. In addition, Jupyter notebooks come with a built-in feature that enables users to open a shell terminal with access to the server.īreaking down the Jupyter Notebook ransomware attackĪccording to the cloud security firm, the latest ransomware sample was executed after the unnamed attacker gained access to the server and downloaded the encryption tools in order to carry out the process by opening a terminal. Some of these notebooks are left exposed to the Internet without authentication, so anyone can access them via a web browser.

A token or password typically restricts access to the online application, as well as limiting incoming traffic. Jupyter Notebook is an open source web application for working with data, writing and executing code, and displaying the results. If organizations do not properly back up Jupyter notebooks, this attack can cause a significant amount of damage to their data analytics. In a report, Aqua Security’s Assaf Morag said the attackers gained access to the server via misconfigured environments before running a ransomware script that encrypts every file on a given path on the server and deletes itself after execution to conceal the attack.
