The first test of a mobile botnet

    Everyone is already accustomed to DoS attacks on the Internet and knows how to do it: thousands of infected PCs form a botnet and at a certain moment begin to simultaneously bombard the specified web server with requests. He does not withstand the load and falls off. As it turned out, a similar DoS attack algorithm is applicable not only on the Internet, but also in cellular networks. The experiment of engineers from the Georgia Institute of Technology writes New Scientist.

    During the experiment, it was checked what size the botnet should be in order to fill up a medium-sized cellular provider. For experience, we took a server with a database such as Home Location Register (HLR), which is available for each operator. It stores SIM card numbers and other information about each subscriber. It turned out that a botnet of 12,000 phones can block up to 93% of traffic (voice and SMS) based on a million subscribers.

    Mobile botnets so far exist only in theory, although there is information that hackers have already checkedthe viability of the idea in practice. A nightmare may well come true if some kind of homogeneous environment becomes widespread on mobile devices or there are many phones of the same model. In this case, one virus can quickly infect thousands of devices at once.
