Experts warn of an increased availability of DDoS tools online, many wannabe hackers download and use them without awareness on consequences. The main concern is that in general many young people are downloading and using theses tools but also the fact that they are told under false illusions to use them. With the release of such applications comes the added threat of users knowingly allowing backdoors to their computer systems to allow the creators access to your device to continue attacks in your absence. Backdoors in a system allow the distributor access but also anyone else who finds the vulnerability.”]
