If you watch TV or go to the movies you no doubt have seen more and more story lines revolving around Cybercrimes, but is any of this realistic and if it is, is it likely? There is no doubt that it exists and there is no doubt that Hollywood
loves scaring the average user, it is their job after all, to entertain you, not enlighten you, and stories about someone receiving pop-ups on their computer will not be making it to the big screen anytime soon.
Criminals taking control of your car’s computer, hacking your computerized prosthetic arm, or inducing a heart attack with your pacemaker is very very unlikely. Hacking into NASA to take control of military drones or for government agencies to take down the nation’s power grids make for good story lines and, while some of these things have already happened in the real world, it is more of something that might happen than is actually happening. According to Brian Murphy, ex Defense Department’s network security unit, “No computer hacker has yet shut down an electrical grid or opened a dam.” So, I ask once again, what does this mean to you and me.
What is CyberCrime
Cybercrime is any crime affecting an individual or group of individuals carried out by the use of a computer. It has grown so much that it is now bigger than illegal drug trafficking as far as making money for criminals. According to Symantec “somebody’s identity is stolen every 3 seconds as a result of cybercrime and your computer can become infected within four minutes after connecting to the internet if you are not protected by a software or hardware protection solution“. A large part of this increase is due to the incredible number of targets available to computer hackers.
In 2011 there were 431 million adult victims of cybercrime in 24 countries. There are 14 cybercrime victims every second and over a million adults affected per day. At least 81% of cybercrime is achieved through hacking, while 59% is achieved with malware that a user invites into their computer through free music, games and porn, etc. The sad part of these statistics is that not all instances are even reported so the numbers are probably even bigger.
Should You Be Afraid?
Yes, scare tactics aside, there is a real and likely probability that you have or will become infected with malware or fall victim to identity theft. Particularly, if you have not already taken the safety measures to prevent it. Even then you must be constantly vigilant to keep yourself safe. I am always amazed at the statements of fellow computer enthusiasts who claim they are 100% safe because they know what they are doing. However, they fail to keep in mind that the one time your grandchild, spouse, or friend uses your computer and clicks on something they should not have, their system will be infected.
Scenarios and Solutions
The virus has the ability to install loggers on your machine and track (log) the keystrokes you make. Even a simple type of Trojan can give a hacker your passwords, credit card numbers and other private information. Once they have your passwords, it is really a simple matter of logging into your accounts and doing as they please.
The other method and the one capable of fooling even a hardened defender is to become infected through a technique called phishing, this is normally when an individual clicks on an email from a trusted website, such as your banking site or any other legitimate site, and is in fact really a fake front embedded with a virus or malware.
The reason this technique is more dangerous is because hackers have evolved and use your own trust against you. For example, once they hack an individual they will then send email to people using the names found in their contacts list. Many of these lists contain the contacts, connection with the user, birthdays, and other comments about the contact.
Imagine receiving an email from your mother with title, “You won’t believe what your dad was doing when we took this photo”. My guess is most people are going to click on that link and open it. Instead of your dad it is a virus. It can be that simple.
Every Cloud Has a Silver Lining
I believe that each of these tactics can be thwarted by taking a few common sense precautions. I am not going to go into great detail on how to prevent data loss because, as I have mentioned, the authors on this site have given you many reliable ways to prevent hackers from accessing your computer, but perhaps the thing we forget to remind
- Keep others off of our computer. Simple enough. If they have to use it, then give them an account with restrictions that deny administrative rights. Make sure that only you can make any changes to the system.
- Prevent downloads from all but authorized sites in their profile
- Scan every download and email attachment no matter the source. Yes, even your spouse or parents.
- Keep your social networking off of any computer which also includes sensitive data.
- Turn off any Wi-Fi device when not in use.
The numbers of serious hacks is alarming but in reality, we are still just a small part of the internet presence.
The criminals work hard to beat our defenses because of the potential profits that can be made by hacking. However, we are getting smarter, becoming more aware and many of us are taking the steps to ensure that not only us but our friends are protected.
