Air France and KLM inform customers that their Flying Blue loyalty program has been hacked. In addition, the data of some customers has been leaked.
This concerns their name, email address, telephone number, last transactions with the companies, and account information such as the number of air miles. So no payment information would have been stolen, and no miles would have been misused to book flights, for example.
While no harm has happened within the accounts, that doesn’t rule out the risk of abuse. With the stolen data, a scammer can call or email the affected customers and impersonate KLM or Air France.
Some customers on Twitter report that KLM informed them about the hack, which KLM also confirms. It does not concern all customers, as Data News inquired with the owners of two Belgian accounts, but no breach has yet been reported there.
The accounts are closed preventively. Anyone who is a victim must therefore change their password when logging in.
