Zepto Ransomware is a dangerous virus that was made to lock files on your computer. It may sneak into the computer with the help of Trojans and viruses. Once executed, Zepto encrypts selected file on the computer using AES algorithm. Like its predecessor called Locky Ransomware, this new version is using the same encryption technique so that they can demand for payment in order for users to recover infected files. The only noticeable difference is the new naming scheme.
While encrypting important files, this ransomware append the extension with .zepto. Then, attacker demands ransom money for decryption instructions. Normally, makers of Zepto virus will demand payment in Bitcoin currency online that does not require them to reveal identity.
Software flaws and vulnerabilities are the common entry point of malware such as this. Executing malicious email attachment triggers the virus to exploit flaws and spread the infection on target computer. Ransomware scans the computer for target files and uses sophisticated encryption method. Then, it provides a ransom note named _HELP_Instructions.html. It is a text file containing instructions to contact the email address provided in order to recover Zepto encrypted files.
System Restore of Windows may help in resolving issues with viruses and malware. However, it will not settle problems with encrypted files. If your computer is running on Windows Vista/7 or later, perhaps ‘Previous Versions’ may help restore files from backup.
