Tor (short for The Onion Router) is software designed to allow someone to remain anonymous when accessing the Internet. It has been around for some time, but for many years was used mainly by experts and enthusiasts. However, Edward Snowden's revelations have resulted in a surge of interest in Tor as more people seek online anonymity.
Cybercrime today is not like the early days of virus writers and hackers who bragged about their exploits with friends. Today cybercrime is a serious business where actually most hackers do not want to be noticed as the longer they remain hidden in the network and are free to conduct their operations, the more information they can steal and the more money they can make.
It's difficult to imagine how cyber warfare could wreak the same havoc as traditional, conventional war. But as former director of national intelligence Mike McConnell once noted, cyber war has the potential to mirror the nuclear challenge - less in the physical sense, but in terms of the potential economic and psychological effects.
For most of today's cybercriminals their activities are not a hobby to brag about with mates. What they do is a serious business to them and they employ many of the best 'traditional' business practices mainstream companies use with the goal of making money. Today's cybercriminal gangs are highly professional and motivated.
Security is now a question of trying to think like the attacker and assume that something bad will eventually happen. Today knowing what you are going to do before, during and after the attack is the thing that will make the difference and lessen the embarrassment and damage a breach could ultimately cause.
Drive-by downloads are a common method used to spread malware. Cybercriminals look for insecure web sites and plant a malicious script into HTTP or PHP code on one of the web pages. This script may install malware directly onto the computer of someone who visits the site, or it may take the form of an IFRAME that re-directs the victim to a site controlled by the cybercriminals.
why is it we seem to value physical over digital so much? We often act very much more recklessly in the digital world than the physical. After all how many of us have taken directions from a friend or colleague to visit a certain website without a second thought? Few people take the trouble to check the validity of the website we are visiting before we go there, or even know what to look for.
