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.

Dark Nexus botnet
Researchers have come across a new botnet named Dark Nexus, that shares similarities with Qbot and Mirai botnets. The botnet is capable of performing DDoS attacks and launching credential stuffing attacks against a broad range of IoT devices, video recorders, and thermal cameras. There are three different versions of the Dark Nexus botnet which has been around for three months.
Anchor backdoor malware
FIN6 APT group and the operators of the Trickbot malware have paired up together to target several organizations with Anchor backdoor malware. The attack campaign, which has been active for the past six months, is initiated through malspam. Most of the enterprises that include Point of Sale (PoS) systems have fallen victim to the campaign.
XHelper trojan, which has been around since March 2019, has infected at least 45,000 devices across the globe. 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.
