Operation NightScout

Also known as: Operation NightScout

(ESET) In January 2021, we discovered a new supply-chain attack compromising the update mechanism of NoxPlayer, an Android emulator for PCs and Macs, and part of BigNox’s product range with over 150 million users worldwide. This software is generally used by gamers in order to play mobile games from their PCs, making this incident somewhat unusual. Three different malware families were spotted being distributed from tailored malicious updates to selected victims, with no sign of leveraging any financial gain, but rather surveillance-related capabilities.
