VERY IMPORTANT

During what began as a routine incident response process, Morphisec has identified (and prevented) a new .NET infostealer variant called Jupyter. Morphisec discovered this variant as part of assisting a higher education customer in the U.S. with their incident response. Jupyter is an infostealer that primarily targets Chromium, Firefox, and Chrome browser data. However, its attack chain, delivery, and loader demonstrate additional capabilities for full backdoor functionality.
