What happened

NetMile reports possible repeated unauthorized logins using email addresses or other information obtained elsewhere. It asks users to change their passwords, especially if they reuse the same information on other services. [1]

The notice does not quantify unauthorized logins or reward redemptions, or identify newly leaked personal data. This is a separate event from the mailing-provider leak; no causal connection is stated. [1]
