Researchers have created a new framework dubbed MarioNet that allows an attacker to control a victim’s browser and all of its resources. MarioNet is a three-step system involving components the researchers call the distributor, servant, and puppeteer. The puppeteteer remains on the victim’s system, communicating with a C2 server, directing the execution of malicious code, and controlling the code’s use of computer resources in order to remain as elusive and evasive as possible. The new threat is critical because malicious hackers have been figuring out how to weaponize HTML5’s features.”]
