Several major companies all over the world, including telecommunications companies and England’s National Health Service (NHS), are currently being targeted by a massive ransomware campaign that has already caused chaos in the affected organizations. Security researchers have allegedly identified the ransomware strain WannaCry, even though the attack’s origin is still unknown.
