We recently caught a malvertising attack distributing the malware Glupteba. This is an older malware that was previously connected to a campaign named Operation Windigo and distributed through exploit kits to Windows users. In 2018, a security company reported that the Glupteba botnet may have been independent from Operation Windigo and had moved to a pay-per-install adware service to distribute it in the wild. The activities of the actors behind Glupteba have been varied: they were suspected of providing proxy services in the underground, and were identified as using the EternalBlue exploit to move into local networks and run Monero (XMR) cryptocurrency miners.
