What is anti-check technology? That anti-detection technology.In the hacker attacks, the most important part of the invasion of the host is not successful, but clear traces, do not let the managers were found to be invasive and data forgery.Similarly, social engineering can have such a concept, then what we have to clear the traces from the network to the Police (hereinafter referred to as Internet police) findings? This section we look at the issue from the perspective of Internet police to see how they come tohas found traces of social engineers.Or a joke: they can not be so easy to find a trace.Here to explain our case, please note that this is a virtual case, inappropriate, please correct me.

Late last year, the network appeared ARP spoofing types of Trojan viruses and hacker attacks by fake IP address and MAC address to achieve ARP spoofing, ARP mechanisms these viruses use the weakness, variety, small batch, fast variant, a high school student iscan be developed, with a clear account of the purpose of theft.Large-scale anti-virus software companies usually only on the impact of large, spread far, have an influence on the virus would provide the virus database upgrade, the spread of these small-scale Trojan often inadequate, and it can not fundamentally eliminate the virus.

Spread of the Internet is now a way is to use the additional traffic for denial of service attacks, this attack, only one file, just a few lines of code to access the file by the user, they unknowinglycircumstances to bring the number of times your target, or even hundreds of times of visits, when the file reaches a certain number of visits, the pressure will be brought to each other is very scary.Moreover, this attack is the attack source ordinary users can not do anything in the firewall settings above can be said to guard against.However, one foot in mind that, there must be a spear, shield, this attack is difficult to maintain, but certainly not not protection.What defensive measures are discussed below.
