On hacking the system by ransomware, the hacked party is asked to pay to get the decryption tools to unlock the system and have access. However, there could be an error within the code of ransomware which centres around randomness. As we know. encryption-decryption keys rely on being almost impossible to guess — these are mathematically linked pair. Digital passwords are long and could not be deciphered by forced scrolling through each possible combination to detect if it works. If the tools are not used properly, say coding one part and using computer clock time for another, the coded part could be uncovered and computer running time could be calculated before the malware is deployed. There could be intelligent guesses of the set of numbers to create a cryptographic key that could match.

Modern hacking is being used by the vast community of hackers, many of whom do not understand the tools they use. In addition, hackers and malware writers are two distinct groups. They are not experts in their fields. They are likely to repeat the flaws and provide clues to the researchers. It is not true that all hackers are geniuses.
