The information reportedly comes from the individual who manages Mirai Botnet #14, and who goes by the online handle of BestBuy. However, they also noted that at least one of the already generated domains wasn’t registered.Īccording to a report from BleepingComputer, however, there’s a clear explanation on why that happened: Mirai is moving to Tor (The Onion Router) domains, because they are far more difficult to shut down. The researchers managed to brute-force the new DGA as well, and they even provided a list of the domains the Mirai samples will supposedly use before the end of the year. What’s more, the botnet operators exercised a strict time control over the domains creation, to ensure that the overlap window was very short. online, one of the TLDs observed in the previous samples. The new domains were said to belong to new Mirai variants, because layer 2 (L2) domain had the same 12-character length, a-y only, and because all TLDs for these domains were fixed to. Thus, new domains that matched the Mirai DGA algorithm but no longer featured the previous seed series were detected. In a new post, the security researchers reveal that newly observed Mirai samples dropped the initial seed series and adopted a new one.
Researchers with the China-based Network Security Research Lab at Qihoo 360, who managed to crack the Mirai DGA, said last week that multiple Mirai samples were using the functionality, and that they were leveraging three different top-level domains (TLDs) for that. The attacks were revealed to leverage the TR-064 vulnerability, which can be used to steal WiFi network keys in addition to recruiting the router into a botnet. Soon after, the same malware attack was confirmed to have also hit around 100,000 UK TalkTalk and Post Office ISP users.
In late November, a Mirai variant managed to hijack 900,000 routers from German ISP Deutsche Telekom using port 7547. The DGA feature was associated with Mirai Botnet #14, which reportedly had over 3 million ensnared devices at the end of November.
The DGA functionality in Mirai was detailed about a week ago, but security researchers say that the botnet had been using it for a very short period of time. Onion domains, after briefly flirting with its own Domain Generation Algorithm (DGA). Mirai, the distributed denial of service (DDoS) botnet that leverages the power of Internet of Things (IoT) devices, is improving resilience by switching to.
