It was only last week that security researchers had come across a new and sophisticated Dark Nexus botnet that shared similarities with the notorious Mirai botnet. Now, following the same pattern, a new botnet, dubbed Mozi, has been discovered that borrows source code from Mirai, Gafgyt, and IoT Reaper botnets. The newly found Mozi botnet is capable of targeting unpatched home routers and DVRs, among other IoT devices.

A new variant of NetWire RAT that uses a legacy Microsoft Excel 4.0 macro to avoid detection by security solutions, has also been spotted in the last 24 hours. The variant is used in a new malspam campaign that targets US taxpayers.

Meanwhile, the wireless router maker, Linksys, was forced to reset the passwords of all its customers due to a COVID-19-themed malware attack. It was found that some of its customers were redirected to a fake website that prompted them to download an app that provided the latest instructions and information about the disease.

The breach had occurred on January 20, 2020, when an intruder gained access to one of the company’s databases that was left exposed online due to a misconfiguration.
