reference profile · reported nexus: KR (not nationality)
Kaspersky described DarkHotel in a 2014 report as: '... DarkHotel drives its campaigns by spear-phishing targets with highly advanced Flash zero-day exploits that effectively evade the latest Windows and Adobe defenses, and yet they also imprecisely spread among large numbers of vague targets with peer-to-peer spreading tactics. Moreover, this crews most unusual characteristic is that for several years the Darkhotel APT has maintained a capability to use hotel networks to follow and hit selected targets as they travel around the world.'
