Cybersecurity researchers today disclosed a new supply chain attack compromising the update mechanism of NoxPlayer, a free Android emulator for PCs and Macs.
Dubbed “Operation NightScout” by Slovak cybersecurity firm ESET, the highly-targeted surveillance campaign involved distributing three different malware families via tailored malicious updates to selected victims based in Taiwan, Hong Kong, and Sri Lanka.
NoxPlayer, developed by Hong Kong-based BigNox, is an Android emulator that allows users to play mobile games on PC, with support for keyboard, gamepad, script recording, and multiple instances. It is estimated to have over 150 million users in more than 150 countries.
First signs of the ongoing attack are said to have originated around September 2020, from when the compromise continued until “explicitly malicious activity” was uncovered this week, prompting ESET to report the incident to BigNox.
“Based on the compromised software in question and the delivered malware exhibiting surveillance capabilities, we believe this may indicate the intent of intelligence collection on targets involved in the gaming community,” said ESET researcher Ignacio Sanmillan.
