Analysis Summary
NoCry ransomware is an insecure cryptomalware first discovered by security researcher S!Ri. Once this deadly malware successfully infiltrates Windows PCs, it encrypts all victims’ key files and data stored on their systems and asks them to pay for a decryption tool/software. It initially modifies Windows registry settings by writing brute force entries in them to create persistence. After that, this dangerous threat scans the entire computer to find the files that are in its target list and once detected, it locks each of them using a powerful encryption algorithm. Infected files are easy to identify because they append the “.Cry” extension to each one.
