Evasive Jupyter Infostealer Campaign Showcases Dangerous Variant

Security researchers have noticed a surge in attacks involving a new variant of the malware Jupyter, which targets browsers like Chrome, Edge, and Firefox. Also known as Yellow Cockatoo, Solarmarker, and Polazert, the malware steals credentials from victims’ systems and can function as a backdoor to computers. VMware noted that the recent infections utilise multiple certificates, enhancing Jupyter’s evasion capabilities and enabling its malware to appear as trusted files, thereby gaining initial access to victims’ machines.
