Russian-speaking hackers have been using a new malware to steal information from their victims. Named Jupyter, the threat has kept a low profile and benefited from a fast development cycle. Researchers at cybersecurity company Morphisec discovered that the developers of the attack kit were highly active, some components receiving more than nine updates in a single month. The constant modification of the code, though, allows it to evade detection and enables it to collect more data from compromised systems. The developers extend the range of information targeted.
