In July 2008, hackers broke into a computer at Wyndham Hotels. They stole tens of thousands of customer credit card records, including guest names, card numbers, expiration dates and highly sensitive data from the cards’ magnetic stripe.
It’s a company’s worst nightmare, particularly in the face of an economic downturn, and to make matters worse, it wasn’t until September that Wyndham realised that the theft had occurred. The company remains uncertain about how many individual credit card accounts were adversely affected by the Wyndham incident, however, it’s probably safe to say that most holiday-makers will think twice before putting their holiday on credit!
So exactly how did such a crime occur? The fraudsters involved in this affair had clearly devised a sophisticated plan to steal the information, but the truth is, thousands of hackers steal credit card information every day, using much simpler tactics.
Two main strategies are commonly used by hackers to access credit card information: through password theft and via a virus or Trojan horse.
Password Theft
Cracking someone’s password is the most common method that hackers use to bypass security software, and access data such as your credit card information.
A password is really just a simple combination of letters, numbers and special characters – and, thus, there are a select number of combinations that can be generated. A high-end computer will be able to, eventually, crack any password, no matter how complicated or long it may be, but you can take certain measures to combat their efforts.
To protect yourself as a consumer, your best bet is to create the strongest password possible. This means a unique combination of letters and numbers, special characters if you can remember them, and even a mix of lower and upper cases if possible. The stronger your password, the longer it takes for the computer to crack – and the longer it takes to crack, the greater the risk of the hacker getting caught. Easy passwords will get cracked first, so aim for complex, long and unusual combinations.
Worms, Viruses and Trojan Horses
Viruses appear in all shapes and sizes, and have many – mostly nasty – purposes. Some viruses are written to delete your files, and others are written to send out lots of spam – but the absolute worst viruses will infect your computer and collect valuable information. These are called Trojan Horses.
Trojan Horse’s will typically install itself and run hidden in the background, and the user of the computer – yourself – is none the wiser that to it even being there. It sits silently and collects data on everything you are doing, from logging into your online banking to making purchases over the internet, and then sends that information back to its creator.
What must be noted about Trojan Horses is that you must open the virus for it to be enabled – so if you practice extreme caution when browsing the web and opening emails, you should be able to avoid any corruption.
If you receive an email from ‘Jenny Shields’ with an attachment that says ‘Great_picture.exe’, for example, and you don’t know anyone called Jenny Shields, then delete the email immediately. When surfing the internet, if a bright and flashy pop-up demands your attention to claim a prize, don’t click on it – it’s a scam. Practicing common sense will definitely help you avoid becoming a victim.
You should also consider using anti-virus and anti-spyware software to help keep your identity safe. Usually, this software will search for viruses on your computer and in your inbox. It’s available for free, and the protection it offers could save you a lot of time, money and hassle in the long run.
By enforcing these simple rules into your day to day routine and using a trusted credit card can instantly lower the risk you’re at from fraudsters infiltrating your life!
