Last week we discussed how a data breach could affect your business. This week we will be taking a look at some of the biggest data breaches to occur in the world.
Here are just three examples of the biggest data breaches to occur in the world so far:
Heartland Payment Systems
- 2008-2009: 130 million records compromised
- Malware on Heartland’s network recorded card details as it arrived from retailers
- Albert Gonzalez who was behind the hack was sentenced to 20 years in prison which was the longest sentence ever handed down for computer crime in a U.S. court
- 2013: 110 million records compromised
- In December 2013 US retail giant Target’s payment card readers were hacked and around 40 million credit and debit card numbers were stolen
- In January 2014, Target announced that the contact information of 70 million customers had also been compromised
Sony Online Entertainment Services
- 2011: 102 million records compromised
- Attackers exposed login credentials, names, addresses, phone numbers and email addresses of users.
- The PlayStation Network remained offline for three weeks after the breach and costs were estimated at around $171 million
Recent research shows that fresh credit card data is worth around £20 on average on the black market, making a large breach very profitable for someone who is seeking to sell this sort of information on.
