An anonymous reader writes: Two hackers are renting access to a massive Mirai botnet, which they claim has more than 400,000 infected bots, ready to carry out DDoS attacks at anyone's behest. The hackers have quite a reputation on the hacking underground and have previously been linked to the GovRAT malware, which was used to steal data from several US companies. Renting around 50,000 bots costs between $3,000-$4,000 for 2 weeks, meaning renting the whole thing costs between $20,000-$30,000. After the Mirai source code leaked, there are countless smaller Mirai botnets around, but this one is [believed to be the one] accounting for more than half of all infected IoT devices...that supposedly shut down Internet access in Liberia. The original Mirai botnet was limited to only 200,000 bots because there were only 200,000 IoT devices connected online that had their Telnet ports open. The botnet that's up for rent now has received improvements and can also spread to IoT devices via SSH, hence the 400,000 bots total.
Interestingly, the article claims the botnet's creators had access \to the Mirai source code "long before it went public."
