What do we know about Europe’s freezer hacks?

Seven international flights have been grounded since Monday following bomb threats, although it remains unclear if these incidents are linked. Simultaneously, Europe has experienced freezer hacks where temperatures were remotely increased to 55C. This malicious activity resulted in the destruction of food supplies valued at millions of euros. Both situations highlight significant security vulnerabilities across different sectors in Europe, affecting both aviation safety and the integrity of food storage systems through remote technical interference.
