Why Do People Create Viruses?

Why Do People Create Viruses?Writing a computer program is hard and writing a virus is even harder (BTW you don’t even need programming skills as viruses templates can be bought online), so why do people do it? In the majority of instances it comes down to 3 reasons:

  • Money
  • Bragging rights
  • Simply being a jerk.

While bragging or being a jerk is pretty self-explanatory, the money side is more interesting. Here are some of the ways people make money with viruses:

Bank account theft: As with real bank robbers virus creators are more than happy to help themselves to the money in your bank account. Once they have your login details (obtained via a key logger) they simply transfer your funds away or use your credit card details to go on a shopping spree. Sometimes they’ll leave the fun to another person by selling your details to the highest bidder.

Ransomware: Sometimes a virus will encrypt your files and demand money for a key to unlock you own data. Without a true backup procedure in place you are at their mercy.  Once you have paid the nightmare may not be over as they now know you are an easy target and request even more money.

Ad swappers: A very cheeky technique which you may never know is happening to you. This scam is when a virus puts annoying ads on websites you visit or places affiliate codes on pages. When you buy something legitimately – eg, from Amazon – the affiliate codes allow the hacker to get a percentage as a ‘referral fee’. Their kickback doesn’t make your purchase cost more and you may not even know you are infected.

Bitcoin mining: You have heard of digital currencies being used for payments but did you know you can also earn money via bitcoin mining? You can earn this money by running specialized software on your computer but sometimes this means paying more in running costs than you would actually make – unless you were very clever and sneaky, and used a virus to use the processing power on other people’s computers.

Botnets: If infected with a botnet, a computer can be remotely controlled to do whatever the virus creator wants. In most cases they’ll usually set the infected computers to overwhelm a target computer and blackmail the owners of that computer – the ‘Botmaster’ says “pay me thousands of dollars or I’ll crash your computer.”

Account stealing: Subscription accounts like Netflix and Hulu are often hijacked allowing other users a free ride by using your accounts. Gaming accounts open up another world of financial incentives with those digital items that people work hard for in the games worth a pretty penny on the black market.

These are just a few of the ways people make money through viruses and malware. If you know of any others please leave a comment below.
