Rewterz Threat Alert – New Mirai Variant Uses Multiple Exploits to Target Routers and Other Devices

May 29, 2019

Severity

Medium

Analysis Summary

A new variant of Mirai exploiting a large number of vulnerabilities. This variant leveraged 13 different vulnerabilities targeting routers, surveillance products, and other IoT devices. Though all of these vulnerabilities have been seen in various Mirai variants, this is the first variant containing exploits for all 13. Once exploited, a victim device connects to both its C2 and a few downloader/dropper URLs. It then spreads to other devices on the network by scanning for and exploiting detected vulnerabilities or performing brute force attacks.
