There are only the sites and services Internet which are subject to known denial of service attacks – common phones, whether mobile or not, are also subject to suffering such blows. That’s what the site revealed The Register that, on Monday (23), brought the story of TNT Instant Up, a device created by hackers Eastern Europe just facing this purpose.
Sold on the Internet by values ranging between $ 500 and $ 1,200, the equipment uses an interconnected system of SIM cards and modems to bomb one or more numbers linked. Calls are empty and only serve to clog the lines, preventing legitimate users are able to access them
The idea here is basically the same as any attack DDoS :. Prevent the use services. But, here, they are not removed from the air, but only end up congested and unusable for the duration of the attacks. The practice is being called TDOs, short for Telephone Denial of Service , or denial of telephone service.
The problem is that in the new modality, the results would be much more dangerous . While most of the scams of this type cause financial losses to affected companies and inconvenience to its users, it TDOs would be able to, for example, block emergency services.
Furthermore, the TNT Instant up would be simple enough to literally anyone could use it. In a demonstration video freely available on YouTube, one of tool vendors shows up with various cell at the same time, with numbers that are entered from a running software on a computer. Trading in the “merchant” happens ICQ or email and the product is sent by mail as any conventional electronic.
The FBI would have identified at least two circumstances in which a device such as TNT Instant Up was used to prevent user access to health service plan or emergency lines. Nevertheless, did not identify crimes that were being made in relation to the attack and that would justify blocking the line and trying to prevent citizens to contact the police, for example.
According to the information of IntelCrawler , a provider of systems and security solutions, as well as in denial of service attacks on the web, there are ways to protect against this new type of coup, unless, of course, disconnect the line to phone stops ringing nonstop. An alternative that simply does not exist for emergency services, especially now become more of a tool target that can be used by anyone, whatever her intent.
