Business Insider Edition
Data breaches are on the rise for all kinds of businesses, including retailers.
At least 10 consumer companies reported data breaches in the last year. Many of them were caused by flaws in payment systems either online or in stores.
A recent report published by cybersecurity firm Shape Security showed that 80-90% of the people who log in to a retailer's e-commerce site are hackers using stolen data. This is the highest percentage of any sector examined in the report.
These data breaches are a real danger for both companies and customers, as they can damage the trust shoppers have in brands.
According to a study by KPMG, 19% ofconsumers said they would completely stop shopping at a retailer after a breach, and 33% said they would take a break from shopping there for an extended period.
Here are the consumer and retail companies that suffered a data breach in the last year:

Marriot disclosed a massive breach of data from 500 million customers in late November .
Guests staying at any of the Starwood brand's hotels, including W Hotels, St. Regis, Sheraton, Westin,Element, and Aloft, on or before September 10, had their data exposed.
Exposed information included names, mailing addresses, phone numbers, email addresses, passport numbers, dates of birth, gender, and other Starwood account information.
Encrypted credit-card information was also exposed, and, potentially, the key to decrypt it.
"Marriott reported this incident to law enforcement and continues to support their investigation," the company said at the time. "The company has already begun notifying regulatory authorities."
Arne Sorenson, Marriott's president and CEO, said: "We deeply regret this incident happened."

Signet Jewelers, parent company of Kay Jewelers, had a vulnerability in its website that exposed customers' information after they had purchased jewelry online.
By changing the link customers received confirming online orders, anyone could access information including customers'names, the order's billing address, shipping address, phone number, and email address, plus the number of items and total dollar amount for the order, the delivery date, and a tracking link.
Only the last four digits of a customers credit-card number were on the page, however.
The issue was fixed in November for orders going forward. It was fixed for past orders in December, according to Krebs on Security.

Adidas announced in June that an "unauthorized party" said it had gained access to customer data on Adidas' US website. Currently, the company believes only customers who shopped on and purchased items from the US version of Adidas.com may have been affected by the breach.
The data that is potentially at risk includes customer contact information like email addresses and physical addresses, as well as login information like usernames and passwords. The passwords were stored with an encryption, however, which would need to be unencrypted before they could be used.
Adidas did not say exactly how many customers could have been affected by the breach, but an Adidas spokeswoman confirmed it was likely "a few million."
