Botnets (infected computers controlled by cybercriminals) are a global problem without a clear-cut solution. Despite the best efforts of security response teams, the fight against botnets is hamstrung by legal and technical issues. Taking over an international botnet in order to disinfect the drones without permission from the infected victims is a classic example of action being technically possible, but restricted by law. More recently, law enforcement agencies have pursued some avenues to help with disinfection, but there are still ethical issues to overcome. This panel discussion will examine some real-world botnet scenarios and review the limitations of countermeasures. It will also look at some of the ethical issues and propose some basic guidelines to help law enforcement agencies crack down on botnets.
