Do you know what Kozy.Jozy Ransomware is?
Kozy.Jozy Ransomware is a recently created malware that might be sold as a kit too. Like any other ransomware, the malicious program encrypts user’s files and adds another extension to them. It was noticed that this extension has a few different versions. This is why computer specialists think that the malware could be sold as a kit, which could be slightly altered by the person who purchases it. Further in the article we will also explain to you, how this infection spreads and how to erase it. If you do not have any copies of your data, this might be a tough decision to make. However, if you are asked to pay a huge ransom, it is better not to lose your money too. Since the ransomware’s creators might not bother to send you the decryption key.
Kozy.Jozy Ransomware should be distributed through malicious executable files that look like Microsoft Word documents, e.g. “карточка ООО Скрит.docx.exe.” Its icon should have the appearance of a text document, but the .exe extension at the end says that the file is actually executable. The next time you receive a suspicious email attachment from an unknown source, you should investigate it firstly. For instance, users could check it with a reputable antimalware tool or search for any related information on the Internet. If you are not the first user who infected its computer with particular ransomware, you should find some topics about it on specific web pages.
Once, you download and open the malicious attachment, the malware starts encrypting your data. It can lock file types that have these extensions: .cd .ldf .mdf .max .dbf .epf .1cd .md .pdf .ppt .xls .doc .arj .tar .7z .rar .zip .tif .jpg .bmp .png .cdr .psd .jpeg .docx .xlsx .pptx .accdb .mdb .rtf .odt .ods .odb .odg. Data that was locked should have .31392E30362E32303136_(0-20)_ZHM1, .31342E30362E32303136_(0-20)_KTR1, or similar extension that fits the pattern.
