"I regret to inform you that late last week we identified a security breach that may have compromised the email addresses and hashed passwords … for a small subset of Flightradar24 users (those who registered prior to March 16, 2016), including you.
As the message offered a link to reset passwords, some members worried that it was a phishing scam. Flightradar24 personnel therefore hit the service’s forums to confirm the mails were genuine."

“We would also like to stress that we have no indication any of personal information was compromised” wrote a staffer named Olga. “The security breach was limited to one server and it was promptly shut down once the intrusion attempt had been ascertained,” she added, along with news that no payment data was compromised because the site doesn’t have it.

However she advised recipients of the mail “.. to change the password for your FR24 account. In case you’ve used the same password anywhere else, we strongly suggest you update it there as well.”
