(AP Photo/Elise Amendola, File)WASHINGTON The U.S. Treasury Department has fined Capital One $80 million for careless network security practices that enabled a hack that accessed the personal information of 106 million of the banks credit card holders. Among the largest of its kind on record, the 2019 breach compromised about 140,000 Social Security numbers and 80,000 bank account numbers. The accused hacker, former Amazon software engineer Paige Thompson, has pleaded innocent to charges related to the breach. No evidence has emerged that Thompson sought to benefit financially from the hack.

The complaint also references a Slack channel and says she posted there under the name "erratic." Another site erratic listed as being the "ohio.gov dept of transportation." Erratic listed only filenames in the Slack channel, and not files themselves. "We investigate and fend these off daily, and it's hard to know if one of them recently was alleged hacker from the Capital One situation. I did flag the slack channel posting and our team is looking into it, but even that wasn't much for them to go on."

(CNN) - In one of the biggest data breaches ever, a hacker gained access to more than 100 million Capital One customers' accounts and credit card applications earlier this year. Capital One said the hack occurred March 22 and 23 and includes credit card applications as far back as 2005. However, "no credit card account numbers or log-in credentials were compromised and over 99% of Social Security numbers were not compromised," the company noted. Capital One said it will notify people affected by the breach and will make free credit monitoring and identity protection available. One person who saw the information on GitHub notified Capital One of the "leaked data" belonging to the company.

Among other information, the compromised data included some Social Security numbers. The department alleges that Thompson "posted on the information sharing site GitHub about her theft of information from the servers storing Capital One data." The breach affected around 100 million people in the United States and about 6 million people in Canada, according to Capital One. However, "no credit card account numbers or log-in credentials were compromised and over 99% of Social Security numbers were not compromised," the company said.
