In late 2022, SafeBreach commissioned S&P Global Market Intelligence to conduct a research project surveying 400 highly qualified security practitioners across the United States and Europe. The goal was to understand respondents’ biggest security challenges, the level of adoption and maturity of the continuous security validation (CSV) tools they use to address those challenges, and the business outcomes they achieved.
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.
In this blog post, the KrakenLabs team will take a deep dive into a malware sample classified as LummaC2, an information stealer written in C language that has been sold in underground forums since December 2022. We assess LummaC2’s primary workflow, its different obfuscation techniques (like Windows API hashing and encoded strings) and how to overcome them to effectively analyze the malware with ease.

This analysis is intended to help the cybersecurity community better understand the wider obfuscation and padding tricks Emotet is using.
