An updated version of the Fallout exploit kit recently emerged with an exploit for a recent Flash zero-day included in its arsenal, Malwarebytes Labs security researchers warn.
First detailed in September 2018, the toolkit was observed delivering malware families ranging from ransomware to backdoors, but also fingerprinting the browser profile to identify targets of interest.
The exploit kit (EK) remained active throughout the end of 2018, but its operators took a break in early January, apparently in order to improve their malicious kit. During Fallout’s absence, RIG EK’s activity intensified, Malwarebytes now reveals.
