Romania's Rompetrol gas station network has been hit by a ransomware attack.A subsidiary of KMG International, Rompetrol announced today that it is dealing with a "Complex cyberattack" that forced it to shut down its websites and the Fill&Go service at gas stations.

Ransomware encrypts data and demands a ransom in exchange for decryption. As data recovery is impossible if the encryption key is not obtained, some companies suffer from considerable damage, such as the payment of huge amounts of money or the loss of important data.

Researchers have detailed what they call the "First successful attempt" at decrypting data infected with Hive ransomware without relying on the private key used to lock access to the content."We were able to recover the master key for generating the file encryption key without the attacker's private key, by using a cryptographic vulnerability identified through analysis," a group of academics from South Korea's Kookmin University said in a new paper analyzing its encryption process.
