What is JENNY Ransomware

JENNY is the name of a new file-locker discovered by MalwareHunterTeam. Malware of such is normally designed to restrict access to data and demand victims to pay a ransom in crypto. After successfully infiltrating the system, the virus encrypts important pieces of data and also assigns the .JENNY extension. This means a file like 1.pdf will change to 1.pdf.JENNY and reset its original icon to blank. After this part is done, the ransomware replaces desktop wallpapers and features a pop-up window right on the screen.

Unlike other ransomware infections, JENNY developers do not provide any decryption instructions. Victims are left confused with absolutely no contact information to use for reaching the cybercriminals. The reason for that could be because this ransomware is still under development and is likely being tested. This means decryption with the help of developers is impossible and that a complete version of JENNY may be released some day in the future. As of now, the best possible way to recover your data is via backup copies of it. You can otherwise try some third-party decryption and recovery tools presented in our guide, however, many ransomware infections are immune to them due to strong algorithmic cipher assignments that occur during encryption. Before you try to return your files, it is important to delete the virus from your system first. Although it will not unlock the already restricted files, it will prevent malicious operation of JENNY Ransomware and ensure no further damage is going to take place.

How JENNY Ransomware infected your computer

Cybercriminals tend to deliver malware by masking it under something legitimate. For instance, many users receive e-mail spam messages claiming to open maliciously-modified attachments (.DOCX, .PDF, .EXE, .JS, .RAR, . ZIP, etc.). It may also be a link leading to some malicious download website as well. As said, such messages are being ostensibly sent from legitimate sources like DHL, FedEx, DPD, IRS, Banks, and so forth. It is often inexperienced and inattentive users who become victims of such distribution techniques – they do not think the received messages are suspicious and therefore infect themselves with malware. Other techniques such as spreading malware through fake software updates or installers, trojans, network vulnerabilities, backdoors, keyloggers, and more are also designed to work off of users’ inexperience. This is why it is important to double-check any information you get and download software only from verified resources. We also advise you to read our tutorial below as there will be some useful information about malware protection you might capitalize on.
