Ransomware
Abuser: Wannacry returned
WannaCry returned! All your devices were hacked with our program installed on them. We have perfected operation of our program, so you will not be able to regain the data after the attack. All the information will be encrypted and then erased. Antivirus software will not be able to detect our program, while firewalls will be emasculate against our one-of-a-kind code. Should your files be encrypted, you will lose them forever. (I did nothing by the deadline: nothing happened)
