Analyzing Penetration-Testing Tools That Threat Actors Use to Breach Systems and Steal Data

The use of legitimate Windows tools as part of malicious actors’ malware arsenal has become a common observation in cyber incursions in recent years. We’ve discussed such use in a previous article where PsExec, Windows Management Instrumentation (WMI), simple batch files or third-party tools such as PC Hunter and Process Hacker were used to disable endpoint security products, move laterally across networks, and exfiltrate information, among others. We have also extensively discussed legitimate tools that…

How Shady Code Commits Compromise the Security of the Open-Source Ecosystem

Traditionally, concerns over open-source code security have revolved around whether or not open-source code could contain vulnerabilities, backdoors, or hidden malicious code. In recent months, however, we have observed a growth in a particular trend: Open-source code is being subjected to modifications to its functionality to express political protest. These instances of so-called “protestware” occur in the form of code changes by certain open-source code maintainers or backers in what could only be surmised as…

Data Distribution Service: Mitigating Risks Part 3

We created an attacker on the network that sends an RTPS payload with parameter Length set to 4 null bytes, causing the DDS layer underneath the ROS 2 node to crash abruptly. The Lidar sensor is still sending information about obstacles, but this is not delivered in time (if at all), causing the control loop to miss deadlines. Consequently, the robot will be blind to obstacles or won’t see them in time. Recommendations Following the…

Unpacking Cloud-Based Cryptocurrency Miners That Abuse GitHub Actions and Azure Virtual Machines

In this section, we cover how malicious actors are leveraging Windows runners in their attempts to mine cryptocurrency, as well as the persistence techniques they use to dodge detection by GitHub to prevent their Actions from being disabled. GitHub provides the runner, a server designed to run workflows (aka Actions). Workflows are deployed on Azure and terminated after an enterprise’s automation is completed. While this service has its limits, users do not pay anything to…
