Amazon has terminated employees responsible for leaking customer data, including their email addresses, to an unaffiliated third-party in violation of company policies. The company has sent out an email announcement to affected customers following the incident. Reports emerged on Twitter of multiple Amazon customers perplexed by the email alerts being sent out by the company describing the data leak. The key concern was if this was an isolated incident targeting the particular customer who had received the email or had other customers been affected too. Amazon did not answer how many customers were impacted.
