It is incredibly important to stay on top of breaches — you never know when one may affect you. That’s why at the beginning of every month, we make sure to provide you with a roundup of recent data breaches.

Here are the top breaches that were making headlines in October 2015:


Early in October, news came that major credit bureau Experian had experienced a data breach. Customers of T-Mobile were affected, as T-Mobile used Experian to conduct credit checks on potential customers and individuals who applied for regular T-Mobile USA postpaid plans — anyone who did this between September 1, 2013, and September 16, 2015, may have been affected. CNN Money reported that hackers stole the personal information of 15 million T-Mobile customers and took customer names, addresses, Social Security numbers, birthdays, driver’s license numbers, military ID numbers, and passport numbers.

It is not yet clear what the hackers intend to do with the information, but Experian is facing a great deal of backlash. Experian has a pattern of breaches and lawmakers are calling for details of the breach to be released. Lawsuits have also already been filed against the company.


A breach at Uber that was disclosed publicly in February of this year was making headlines again in October. In September 2014, Uber discovered that 50,000 of their driver records were compromised by a hacker in May 2014. Uber investigators believed that someone used a company security key accessible on a public website.

Flash forward to this past October, and The Wall Street Journal reported that rival company Lyft may have had something to do with the breach. Lyft has denied that their Chief Technology Officer or any other employees were involved, but Uber feels the evidence their investigators uncovered makes it pretty clear who was responsible. The court has not made any kind of ruling yet and legal proceedings are ongoing.

Trump Hotel Collection

Donald Trump was all over the news during October as he continues his campaign for the U.S. presidency, but his luxury hotel chain was also getting attention for a different reason — a data breach. Trump Hotel Collection posted a legal notice on its website, saying people may have been affected by the breach if they used their debit or credit cards between May 19, 2014, and June 2, 2015, at Trump SoHo New York, Trump National Doral in Miami, Trump International New York, Trump International Chicago, Trump International Waikiki, Trump International Hotel & Tower Las Vegas, or Trump International Toronto.

An investigation into the breach has not shown that any particular customer’s payment card information was taken or misused, but because the system was compromised, the possibility is certainly there. Trump Hotel Collection says they have removed the malware that infected the company’s point-of-sale terminals and are now working to make their network more secure.
