DeepSec Talk 2024: RAT Builders – How to Catch Them All – Stephan Berger
Cybercriminals now have unprecedented ease in creating their own remote access trojans (RATs), thanks to a plethora of open-source or leaked builders. One can generate a new binary with just a click of a button. We meticulously examine different builders, such as AgentTesla, DCRat, Nanocore, and others, to extract Indicators of Compromise. These indicators serve as valuable instruments for targeted hunting to detect infections within our networks. Building up on my research from last year, “N-IOC’s to rule them all”, we will analyze the binaries the same way, but this time with a focus on open-source builders for RATs. Initially, we scrutinize the distribution channels of different Trojans, pinpointing where individual builders are accessible for download. These sources range from GitHub, hosted as open-source projects, to other online platforms (such as VX-Underground). Subsequently, we
