Comixology is the largest digital distributor in the world for digital comics. This often puts them in the media limelight and paints a big target on their back. The company has acknowledged that they have suffered a major data breach today with usernames, passwords and email accounts were accessed by a rogue denizen of the internet.
In a letter sent out to anyone who has ever registered an account with Comixology, the company is encouraging people to change their passwords. Although no credit card or financial data was stolen, it is only a matter of time before all of your data is sold to companies that buy customer information in bulk.
The Comixology servers are currently overwhelmed with password changing requests and it is currently impossible to actually change your user information. This may change in the next few days, but it is unlikely.
Breaching databases and stealing customer data is nothing new. Its been happening more often with companies such as Adobe, that handle the bulk of eBook encryption technology. It looks like hackers are now targeting companies that readers cluster to.
