C0hen Locker ransomware is a new data locking malware that was spotted in the wild at the start of December 2019. Upon infiltration,the virus performs the necessary preparations inside the Windows PC and then scans it for files to encrypt – it targets the most common formats, such as .pdf, .doc, .jpg, .avi, etc. The encryption process is performed with a symmetric algorithm AES, and all the locked data is marked with .c0hen extension, making it inaccessible to its owners. Unfortunately, C0hen Locker ransomware will perform the exact same procedure on all the networked drives if any are found during the infection process.
