'Mariposa' included almost 13 million zombies.
Spanish authorities have managed to take down the Mariposa botnet - one of the largest of its kind which is believed to have infected in 12.7 million computers worldwide - as well as arresting three of its botherders.
Stories of botnets being taken down have become more prevalent recently; however, usually this is by means of taking the command and control centres down - which leaves the computers infected and the crooks behind the botnet free to regain control over their network of zombies. By arresting the botherders themselves, one would hope that Mariposa has been given a more serious blow.
While the botnet was used for a wide range of malicious activities, from identity theft to running DDoS attacks and sending spam, first reports suggest that global spam levels have dropped over the past fews days.
The Guardia Civil, the Spanish national police, has revealed that the three suspects are in their 20s or early 30s. According to a spokesman, they are neither brilliant programmers nor mafiosi who like fast cars and expensive clothes: "The most frightening thing is they are normal people who are earning a lot of money with cybercrime". More arrests are expected in other countries.
