APT Review of the year (DPRK-related paragraph 3)

Kaspersky Securelist

Scarcruft used a new backdoor we call PoorWeb, deployed a 0-day in their campaign at the beginning of the year and used Android malware specially designed for Samsung devices. DarkHotel was also back with a 0-day and new activity, targeting their traditional victims. We were able to establish a connection with a medium level of certainty between DarkHotel and the Konni/Nokki set of activity described by other vendors.
