A huge data breach  in March 2019 exposed the personal information of more than 100 million Capital One customers. As a result, the financial powerhouse has agreed to a proposed $190 million settlement that is set to receive final approval next week.

The plaintiffs in a class action suit claimed that a hacker couldn't have accessed Capital One's Amazon-hosted cloud computing systems if adequate protections were in place. Capital One "knew of the particular security vulnerabilities that permitted the data breach, but still failed" to protect customers, according to their complaint, putting millions at risk of fraud and identity theft.

Capital One did not respond to a request for comment. The company denied any wrongdoing but, in a December 2021 statement, said it was agreeing to the $190 million payout "in the interest of avoiding the time, expense and uncertainty of continued litigation."

The US District Court for the Eastern District of Virginia granted preliminary approval for the deal on Jan. 31, 2022. At that time, prospective class members had until Aug. 22 to file a claim.

But that deadline has now been extended to the end of September.

Here's what you need to know about the Capital One data breach settlement, including how to find out if you're eligible for a payout, how much money you could receive and the new deadline for filing a claim.

What happened in the 2019 Capital One data breach?

In one of the largest financial security breaches in US history, a hacker accessed the personal information of approximately 106 million Capital One customers and applicants in March 2019.

The massive hack went undiscovered for approximately four months before Capital One made it public in July 2019.  

Seattle engineer Paige Thompson, a former Amazon cloud employee, was ultimately arrested in connection with the case. In June, she was convicted of wire fraud and unauthorized access and damages to a protected computer. 

Capital One said Thompson illegally gained access to personal information related to credit card applications dating between 2005 and early 2019 for both personal and small-business accounts. 

"With some of her illegal access, she planted cryptocurrency mining software on new servers with the income from the mining going to her online wallet," the Department of Justice said in a release, adding that Thompson used an alias to brag on social media and online forums about masterminding the attack.

Thompson is scheduled for sentencing on Sept. 15.

In addition to the $180 million class action lawsuit, Capital One was fined $80 million and agreed to enhance its cloud security standards. 

Capital One said it immediately fixed its servers' vulnerability to forged requests when it became aware of the breach. 

What was exposed in the Capital One hack?

Capital One said about 140,000 Social Security numbers and 80,000 US bank account numbers were exposed, as were birth dates, addresses, phone numbers, credit balances, transactions and credit scores.

An additional 1 million Canadian credit card customers and applicants had their Social Insurance Numbers stolen.

No login information or credit card account numbers were obtained by Thomas, the bank said. 

Who is eligible for payment from the Capital One settlement? 

Some 98 million applicants and cardholders are eligible to file a valid claim, according to Capital One, which said it sent letters and emails to members whose Social Security numbers or bank account numbers were exposed in the hack.

How much can I receive from the Capital One settlement?

Class members can collect up to $25,000 in cash for lost time and out-of-pocket expenditures relating to the breach, including unreimbursed fraud charges, money spent preventing identity theft and fees to professional data security services.

You can claim up to 15 hours of lost time spent addressing the issue, at a rate of at least $25 per hour. 

The settlement also provides three years of free identity protection services through the Pango Group, including identity monitoring, lost wallet protection, security freeze capabilities, dark-web monitoring, free account restoration, and $1 million in identity theft and fraud insurance.

When is the deadline to file a claim?

The original deadline to file a valid claim in the Capital One case was Aug. 22 but that deadline has been extended to Sept. 30, 2022.

The deadline for exclusion from the settlement in order to retain the right to pursue separate legal action expired on July 7. 

When will class members receive their payments?

A judge has given preliminary approval for the $180 million settlement. A final approval hearing was initially slated for Aug. 19 but it was rescheduled to Sept. 8.

Assuming the settlement receives final approval, and there are no appeals, checks could be sent out soon after. We'll keep you updated as new information is made available.
