How it happened: Hackers gained access to Adobe’s networks, though exactly how they did it has yet to be publicly revealed. In addition to stealing user information, attackers also downloaded the source code for a handful of Adobe programs, which essentially forms the foundation of the software.

Aftermath: Adobe offered free credit monitoring to individuals who had their credit card information stolen. Others were told to reset their passwords for Adobe products. Password management vendor LastPass set up a site where you can check to see if your email address was one of those stolen; you can find it here.

 

  1. eBay (May 2014)

Number of people affected: 145 million

Information stolen: Customers’ usernames, encrypted passwords, email addresses, and other personal data. No payment information was taken.

How it happened: Attackers used compromised employee login information to get into the company’s network.

Aftermath: EBay issued a statement asking all of its users to change their passwords “out of an abundance of caution.” The company said it would also work to improve security.

 

  1. Target (January 2014)

Number of people affected: 110 million

Information stolen: 40 million credit and debit card numbers, as well as 70 million consumer email addresses.

How it happened: According to Bloomberg, hackers used credentials from an HVAC contractor working within Target to then gain access to the retailer’s network.

Aftermath: Six months later, company CEO Gregg Steinhafel was forced to resign over the breach. In March, Target settled a class-action lawsuit for $10 million with individuals who had their credit and debit cards stolen.

 

4. Home Depot (September 2014)

Number of people affected: 109 million

Information stolen: 53 million email addresses and 56 million credit and debit cards for shoppers at the $80 billion home improvement chain.

How it happened: Home Depot said hackers used a vendor’s login information to access the network and install malware on the retailer’s self-checkout systems, which fed the attackers information on credit card customers in the U.S. and Canada.

Aftermath: Cleaning up after the breach cost Home Depot an estimated $62 million. The company offered free credit monitoring to any customers who used a payment card at a Home Depot store after April 2014.
