ZeroLocker is a new crypto-malware ransomware program which acts in the disguise of a decryption tool which can rescue the data that is locked by the different threats, in case the license of the program is purchased. As a rule, most of the crypto-malware ransomware programs announce the file encryption situation on the user’s computer and ask for a fee in order to unlock them. ZeroLocker pretends to be a decryption tool which can save the data, but the result is that the victim has to pay a fee to the cybercriminal in order to get his data decrypted.
The Nature of ZeroLocker and How Does It Affect Your PC?
ZeroLocker is a file encrypting program for Windows. Similar to the CryptoLocker, this ransomware encrypts the files on the infected computers using a strong encryption algorithm. When ZeroLocker enters the computer and locks the files, the PC user has to pay a certain amount of money in order to purchase the decryption key. ZeroLocker uses some techniques from the CryptoLocker to make the victims pay quickly.
According to the malware researchers, ZeroLocker is different than the similar ransomware programs as it encrypts files in an indiscriminate way. It adds an extension “.encrypt” to all the files it encrypts. In fact, this ransomware encrypts almost all files on the system and not just certain types of files as most of the other ransomware programs do. ZeroLocker however does not encrypt files which are larger than 20 MB or files that are located in directories named “Desktop,” “Windows,” “Program Files” and “ZeroLocker”.
How the Experts Feel About ZeroLocker?
The security experts that have analyzed this ransomware claim that it is not that complex as CryptoLocker. However, the creators of ZeroLocker confirm that they have used a secure algorithm that is unbreakable, which most probably means a complex cryptographic scheme. This most probably means that the files are locked with a public key and the decryption also requires the usage of a private key.
The malware researchers have found out that ZeroLocker does not delete the Volume Shadow Service, which is in charge of the backups of files even when they are not being used. When activated, it can make safe copies when the Windows Backup starts or can create an automatic system restore for all parts on the system. However, most of the users have enabled the System Restore only for the system drives, and they do not use the default backup option.
The security researchers warn that this malware flaw could be eliminated in the next ransomware versions, which will leave the users who haven’t created backup copies of their files with the only option to pay the ransom.
What Do the Cybercriminals Want?
When ZeroLocker infects the computer, it starts encrypting the files, and when the process is completed, the system gets restarted and the PC user gets the ransom message. The required sum is in Bitcoins that are worth some 300 USD, and there is a five days deadline set for transferring the money to a given address. There are also offers for discounts (200 USD fee) in case the victim pays the fee within 72 hours. When the 5-day period ends, the ransom sum is doubled and even reaches 1000 USD in 10 days.
Naturally, most of the law enforcement and security experts advise against payment, however the victims are the ones to make that decision. The experts inform that the encryption key and the rest of the information are sent through a GET request, which results in 404 on the server, which means that the server is not storing this information. So, the victims who pay may still not see their files restored.
The security researchers say that the best way for the users to keep their computer data safe is to make your PC backups and to store the information they have on a drive that is not connected to the affected system.
