The RSA Conference 2023 addressed several key issues and trends in the cybersecurity industry. Generative AI was a key topic of discussion, with attendees, executives and policymakers seeing its potential in both offense and defense in the cybersecurity arms race.

Today’s software developers are tasked with a lot more than just coding. To keep up with the fast-paced software-driven economy, they need to focus on automation, collaboration, security, distribution, data analysis, and agility to ensure quality builds and get releases to customers quickly and securely. DevOps and security professionals need a centralized system of records that provides visibility across the business.

The JFrog Security Research team recently discovered a new malware payload in the PyPI repository, written in C#. This is uncommon since PyPI is primarily a repository for Python packages, and its codebase consists mostly of Python code, or natively compiled libraries used by Python programs. This finding raised our concerns about the potential for cross-language malware attacks.

The risk of supply chain attacks increases as more companies rely on third-party vendors and suppliers for critical services and products. Supply chain attacks have become increasingly prominent in recent years. In 2022, for instance, supply chain attacks surpassed the number of malware-based attacks by 40%.

In this blog post, we’ll provide a detailed analysis of a malicious payload we’ve dubbed “Impala Stealer”, a custom crypto stealer which was used as the payload for the NuGet malicious packages campaign we’ve exposed in our previous post. The sophisticated campaign targeted.NET developers via NuGet malicious packages, and the JFrog Security team was able to detect and report it as part of our regular activity of exposing supply chain attacks.
