Researchers published an analysis of advanced persistent threat (APT) group Evilnum. The group has historically targeted financial technology companies that offer training and investment platforms. Its attacks are few in number but very specific, and the group’s use of legitimate tools in its activity has helped the group fly mostly under the radar. Its attackers use backdoors some custom, others purchased which give them more options to maintain control over victims and backup options in case one of their backdoors is removed. Evilnum’s primary goal is to spy on its targets and steal financial data.”]
