Jdyi ransomware virus

Jdyi ransomware already penetrated many laptops in different parts of the world through easiest method: false messages with viral attachments. Occasionally web-criminals use exploits to penetrate the PC, but well-known program vendors quickly correct them. After the infection, ransomware reviews the PC memory, determines the amount of folders for encryption and their general value. At the moment, each new virus is able to encrypt video, audio, image and text info in all most used formats. Extra attention is paid to business files, because medium and large companies are the main objective for scammers. All programs in the system will be unaffected since criminals are interested only in information. The process is executed via famous AES and RSA algorithms, and its complexity is so above the average level that it cannot be bruteforced. This is the basis for unbelievable efficiency of ransomware in last years: common user, even having a very high experience in suchlike things, will never restore the data, and will have no choice except paying to fraudsters. The only way to recover files is to crack the scam website and withdraw the encryption keys. Some experienced hackers can get these keys via defects in the code of the virus itself.

There is one common feature for all sorts of ransomware: it is much simpler to dodge it than to remove its effects. For ransomware it's most important, because, in contradistinction to common viruses, when you uninstall ransomware from the PC, the consequences of its doings will stay.

    • Monitor the performance of your laptop. Data encrypting is a complex act that requires a large amount of PC resources. If you notice a noticeable decline in system power or notice a suspicious string in the Process Manager, you need to unplug the workstation, load it in safe mode, and scan for malware. Of course, some files will be encrypted, but the other part of them will remain intact.
    • Take notice to the dialog boxes. One of the easiest manners of data restoration is the restoration through Shadow Copies, so hackers have added the removal of shadow copies into the primary functionality of ransomware. The deleting of shadow copies requires admin rights and your acceptance. If you'll think for few seconds before accepting the pop-up, it might save your data and your time.
    • Be careful with the e-mails which contain files. The #1 template of fraud messages is the story about prize winning or package earning. The other efficient type of these messages is a forgery for business correspondence. reports, lawsuits, summaries, Bills for services or goods and suchlike specific documents don't come without warning, and the addressee should know the person who sent it. Otherwise, it is a fraud.
