This article is dedicated to Work ransomware that gets into users' systems around the world, and encrypts their files. In this page we've assembled full info about Work's essence, and how to delete Work from the laptop. In addition, we will explain how to recover the corrupted data and is it possible.

Work ransomware virus

Work ransomware had penetrated hundreds of computers around the world through most effective method: false messages with viral attachments. Sometimes fraudsters use zero-day vulnerabilities to get into the PC, but they are promptly corrected. When infection is done, the virus scans the PC memory, defines the number of folders to be cyphered and their general worth. Nowadays, each modern virus knows how to cypher text, video, image and audio information in all popular formats. Special attention is attracted to business information, because representatives of business are the priority target for scammers. Virus corrupts only information, and doesn't affect the software, so that the man can use the PC to make the payment. The process is made through well-known AES and RSA algorithms, and it is so complicated that that it cannot be bruteforced. Such complexity creates foundation for impressive effectuality of ransomware in recent years: common customer, even having a pretty high knowledge of the PC, will never be able to restore the data, and will have no way out except paying to criminals. The sole method to decrypt files is to find the scammer's webpage and get the master key. Some experienced malware researchers can retrieve encryption keys due to faults in viruse's program code.

The knowledge of computers is extremely important in our world, because it helps user to protect the system from unwanted software. For ransomware it's very relevant, since, unlike most viruses, after removing ransomware from the system, the effects of its doings do not vanish anywhere. To protect yourself, you must understand a few simple principles:

    • Do not accept any changes to your PC, originating from strange software. If the machine is infected by virus, it will attempt to eliminate the shadow copies of your data, to decrease the chances of restoration. The deleting of copies requires admin rights and confirmation from the user. So, not confirming alterations from a unknown program at the right moment, you will reserve the opportunity to recover all corrupted information free of charge.
    • Be cautious with the e-mails which contain files. The very effective pattern of fraud e-mails is the story about prize gaining or package obtaining. The #2 efficient type of fraud letters is a "business messages". summaries, lawsuits, reports, Invoices for goods or services and similar sensitive information cannot come accidentally, and you, as a minimum, should know the person who sent it. In all other cases it is a scam.
    • Monitor the condition of your machine. It requires a big part of hardware resources to encode the files. When the malware starts to work, the CPU speed decreases, and the encrypting process is visible in Process Manager. You may recognize this moment and shut down the system before files will be fully spoiled. These measures, in case of penetration, will save a lot of your information.

You should know that the elimination of ransomware is only the, first move, which is compulsory for the regular work of the computer. If you delete Work, you will not return the files immediately, it will need multiple actions described in the "How to restore encrypted files" paragraph.

Some ransomware can't be uninstalled even through AV-tool, and have other serious mechanisms of security.
