Human Security's Satori research team has discovered a new variant of the Badbox malware, known as Badbox 2.0, which has infected nearly a million Android devices, forming a large botnet. This follows the initial outbreak in 2023, where around 74,000 devices were compromised. Badbox 2.0 targets devices running the Android Open Source Project (AOSP), including off-brand smartphones, internet-connected TV boxes, automotive tablets, and digital projectors. Over 200 applications infected with malware have been identified, primarily hosted on third-party app stores, often mimicking legitimate apps from Google’s Play Store. The operation is believed to involve collaboration among four distinct criminal factions, with all infected devices traced back to China. The botnet monetizes through hidden advertisements and ad-click fraud, while also having the capability to steal passwords from infected devices. Efforts by Human Security, Google, Trend Micro, and Shadowserver Foundation have reduced the number of infected devices by half. Many malware modules were labeled "test," indicating the botnet was still developing, and it is expected that the operators will attempt to revive their network using altered tactics. Additionally, a new variant of Mirai malware, named Eleven11bot, has emerged, compromising thousands of devices, particularly targeting HiSilicon-based hardware.
