Flightradar24, which shows real-time aircraft flight information on a map, has suffered a massive data breach that may have compromised more than 230,000 customers. The Swedish-based company started sending out emails earlier this week with a password reset link, asking them to change their passwords. The company claimed that the breached passwords were hashed, though it did not specify the hashing algorithm or if they were protected using a salt, which adds an extra layer of security to your hashed passwords.
