The controversial budget airline Ryanair was targeted by the hackers who managed to steal almost US $5 million via a fraudulent electronic transfer to a Chinese bank.
The fund that the airline used to purchase fuel for its aircraft was being stolen by the attackers in the attack.
The airline investigated the incident with the bank and relevant authorities and immediately froze $5 million to prevent further fraud.
