Analysis Summary
Jupyter aka Solarmaeket, was first discovered at the end of 2020. This infostealer targeted businesses and higher institutions in a prominent attempt to steal usernames, passwords, and other confidential information as well as install a persistent backdoor on victim systems. The attack primarily targets data from the Chromium, Firefox, and Chrome browsers, but it also has the capacity to open a backdoor on infected systems, allowing attackers to run PowerShell scripts and commands, as well as download and execute further malware. The Jupyter installer is hidden inside a zipped file, with Microsoft Word icons and file titles that appear to be important documents like travel details, a pay raise, or others
The Jupiter attack victims may experience financial loss, data loss, identity theft, the installation of other malware with more capabilities on their systems, problems with online privacy and surfing safety, and other problems.
