It’s a common theme in the news ‘Company X has had a security breach and Y customer details have been leaked’
But what does this actually mean?
Cyber Crime is big business and it is believed that through 2017 Cyber Crime may have cost the world around $600 billion. For many of these criminals it is their day job and your data are their pay cheques.
Among many other methods to obtain money, one tactic is for an attacker to infiltrate a business computer network and find personal data stored on their systems. This could be names, email addresses, credit card numbers and details, passwords etc. This information is then uploaded to marketplaces on the Dark Web for other people to buy.
Taken from Experian, below is an estimate on how much your data can be purchased for on the Dark Web:
People purchasing this information can buy specific pieces of information such as a person’s passport details or bulk data with various categories from many different sources.
Other attackers can then use this information to create further attacks, for example someone could find your full name and a password that was used on a breached website. They could then check online for other accounts under the same person’s name, eg Facebook, Linkedin, on-line banking etc. and then try the leaked password on these sites.
How many of us use the same password for multiple site logins?
Therefore, if your data has been leaked and you have been notified of this, you should take all steps necessary to prevent yourself being the next victim.
