Malware authors are constantly developing sophisticated strains of existing malware to expand their malicious activities. Lately, security experts have unearthed a new botnet dubbed Dark Nexus, that borrows code from Mirai and Qbot botnets. The botnet is capable of performing DDoS attacks and credential stuffing attacks on a wide range of IoT botnets.

While threat actors continue to expand their attack surfaces, organizations are not far behind in patching the exposed security holes. Google has released security updates for 50 vulnerabilities affecting its Android operating system. Four of these flaws are rated as ‘Critical’ and affect 8.0, 8.1, 9 and 10 of Android.

Apple has also fixed a FaceTime bug and a Bluetooth bug by releasing iOS and iPadOS 13.4.1. The FaceTime bug affects devices running versions prior to 9.3.6 of iOS and versions prior to 10.11.6 of OS X EI Capitan.

The malicious payload connects with the C2 server of attackers after scanning and sending device information, including OS firmware version, manufacturer name, and model. Later, it fetches another payload, the Triada trojan, which uses a set of exploits to obtain device root privileges.
