SK Bithumb Cryptocurrency breach of 30k customers

Names, mobile numbers, and email addresses of approximately 30,000 South Korean Bithumb exchange customers were exposed from an employee's home computer.  Bithum has indicated no passwords were stolen but some customers have claimed to have lost their funds as a result.  Bithumb is one of the largest bitcoin exchanges and the amount affected is estimated to be billions of SK Won (almost $1M US Dollars.)

Bithumb has promised to pay 100k Won ($87 USD) to each member whose information was exposed.  Once again, the cost savings of bring your own device (BYOD) has proven not to be equal to the reputation and financial costs to a company which should retain workstation security controls and ownership.
