World's Largest Spam Botnet Adds DDoS Feature

An anonymous reader writes: Necurs, the world's largest spam botnet with nearly five million infected bots, of which one million active each day, has added a new module that can be used for launching DDoS attacks. The sheer size of the Necurs botnet, even in its worst days, dwarfs all of today's IoT botnets, who barely managed to reach 400,000 (albeit the owner of that botnet has now been arrested).

If this new feature would ever to be used, a Necurs DDoS atack would easily break every DDoS record there is. Fortunately, no such attack has been seen until now. Until now, the Necurs botnet has been seen spreading the Dridex banking trojan and the Locky ransomware. According to industry experts, there's a low chance to see the Necurs botnet engage in DDoS attacks because the criminal group behind the botnet is already making too much money to risk exposing their full infrastructure in DDoS attacks.
