ITLOCK ransomware removal instructions

What is ITLOCK?

ITLOCK ransomware was discovered by Cyber Security. This is a malicious program, a new version of Matrix ransomware that is designed by cyber criminals to encrypt computer data and blackmail victims by demanding ransom payments. During the encryption process, ITLOCK opens two Command Prompt windows. Once data is encrypted, each affected file is renamed by changing the filename: an email address, two random strings and the extension are merged to form an extension with the following format: ".ITLOCK" ("[].[random_string]-[random_string].ITLOCK"). Renamed files might appear something like this: "[].8SLV8GMp-hjqo9v3s.ITLOCK". ITLOCK also creates a ransom message in the "!README_ITLOCK!.rtf" file.

Within the "!README_ITLOCK!.rtf" ransom message, cyber criminals state that they have used ITLOCK ransomware to encrypt all files stored on the victims's computer using both AES-128 and RSA-2048 cryptography algorithms. Therefore, there are two possibilities: 1) the data was encrypted twice using both cryptographies, or; 2) the first cryptography was used to encrypt data and the second to encrypt the decryption key generated by the first algorithm. Whatever the case, to decrypt data, two decryption keys are required. Cyber criminals state that to receive them, victims must make contact via the,, or email addresses. They recommend that contact be made using all three email addresses. Victims must also include the assigned ID as the subject of the email. Furthermore, ITLOCK's developers recommend they users attach three encrypted files for free decryption as 'proof' that they have a valid decryption tool. The cost of this tool is not stated, however, they will probably give this once they are contacted. The ransom message includes a warning that any attempts to decrypt data using other software will cause permanent data loss. Although their tool is probably the only method capable of decryption, you are advised never to contact them or pay pay any money. Most cyber criminals ignore victims after they receive ransom payments (usually made in a cryptocurrency). Unfortunately, there are no other tools capable of decryption free of charge. Therefore, if you have a data backup that was created before the infection, we recommend that you restore files from there.

Most ransomware-type programs are used to encrypt data and blackmail people (by making ransom demands) who have infected computers. Common differences are cost of decryption tool and cryptography algorithm used to encrypt data. Examples of other programs of this type include Gorgon, GEFEST 3.0, and .happy. Unfortunately, most malicious programs of this type encrypt data - decryption is then impossible without the involvement of cyber criminals. To avoid data loss, maintain regular backups and store them on a remote server or unplugged storage device. 

How did ransomware infect my computer?

It is not known which method is used to proliferate ITLOCK ransomware, however, most cyber criminals spread these (and other) malicious programs using spam campaigns, Trojans, unofficial (dubious) software download sources, software cracking tools and fake software updaters. Ransomware developers use spam campaigns to proliferate ransomware (and other computer infections) by sending emails that contain malicious attachments. These could be Microsoft Office documents (Word, Excel, and so on), PDF files, archive files (such as ZIP and RAR), executables, and other files. The purpose of these campaigns is to trick people into downloading and opening these attachments, which results in installation of various high-risk computer infections. Trojans cause chain infections: these malicious programs proliferate other infections, however, they must first be installed. Untrustworthy, dubious software download sources such as freeware download or free file hosting websites, peer-to-peer networks such as torrents, eMule etc., and third party downloaders are used to proliferate malicious programs by presenting them as legitimate. By downloading and installing them, many people cause computer infections. Software cracking tools supposedly help users to bypass software activation, however, some of these tools proliferate infections. The same applies to fake software updaters: they infect systems by downloading malicious software rather than the expected updates or by exploiting bugs/flaws of outdated software.

How to protect yourself from ransomware infections?

To prevent operating systems from being infected by ransomware or other threats, download, install, update software, and browse the web, with care. Do not use the third party software downloaders/installers and tools mentioned earlier. Download software using official and trustworthy websites (or other channels) and direct links. Update software using implemented functions or tools provided by official software developers. Do not open files attached to emails (or website links) received from unknown (or suspicious) email addresses without studying these emails first. If the email seems irrelevant, ignore it. Avoid using software cracking tools, since this is classed as a cyber crime and using them might lead to computer infections. Rather than activating software (or operating systems), these tools might install malicious programs. Have reputable anti-spyware/anti-virus software installed (and enabled). These programs detect and eliminate various computer infections before they do any damage. If your computer is already infected with ITLOCK, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
