Voter registration breach
Affected: More than 191 million voters.
Information stolen: First and last names, recent addresses, phone numbers, party affiliations and voter history.
Breach details: Information technology specialist Chris Vickery discovered a voter database on Dec. 20 that contained the personal information of more than 191 million voters. No one source of the leak could be identified, but some of the information may have come from NationBuilder, a firm that offers digital technology for political campaigns. While voter information is publicly available in most states, having data from all 50 states compiled in 1 spot makes it valuable to hackers. The information exposed could be used for phishing attacks, identity theft and extortion. The database has since been taken down.
Affected: 13 million customers using Kromtech's MacKeeper application.
Information stolen: History of products ordered, license information, public IP addresses and user credentials.
Breach details: IT investment and development company Kromtech discovered that a weakness in its MacKeeper application exposed the account details of 13 million customers. MacKeeper is a collection of utilities marketed as being able to keep Mac products clean, safe and running smoothly. Kromtech keeps only certain information for its MacKeeper application, so credit card information wasn't exposed. Still, those who have MacKeeper installed should change their passwords.
Affected: Customers visiting any one of potentially more than 500 restaurant properties throughout the nation.
Information stolen: Credit card holder names, card numbers, expiration dates and internal verification codes.
Breach details: Landry's Inc., a company that manages large restaurant chains, received reports that unauthorized charges were found on some of its customers' cards after those cards were used at its restaurants. The scope of the incident isn't yet known, but Landry's operates more than 500 restaurants, including chains like Bubba Gump, Claim Jumper, Morton's and Rainforest Cafe. The issue reportedly began in May 2015.
