How to remove Ziggy Ransomware and decrypt .ziggy or .optimus files

What is Ziggy Ransomware

Ziggy is a new ransomware-infection recorded in December 2020. The virus sneaks into your system disabling all protectionary layers on your PC. Then, it gets the job done by running data encryption with AES256-GCM and RSA-4096 algorithms. These ensure strong encryption, which is hard to decipher. Before going deeper into details, it is important to say that there are two versions of Ziggy Ransomware. The first uses the .ziggy extension along with victims’ ID and cybercriminals’ e-mail to configure the data. The later version of Ziggy Ransomware detected recently started involving the same string of information but changed the extension at the end to .optimus. For example, a file like 1.docx would change to 1.docx.id=[88F54427].email=[khomeyni@yahooweb.co].ziggy or 1.docx.id[B68A285D].[sikbeker@tuta.io].optimus depending on which version affected your PC. Following successful encryption, the malicious program creates a text file containing decryption instructions. The name of the files can vary from version to version, so there is no commonly-used, but initially, it was called ## HOW TO DECRYPT ##.exe.

The content included inside is more-less the same with minimal changes. As a rule, Ziggy developers ask victims to contact them via e-mail attaching personal ID. After this stage is passed, people will get the payment details to purchase the decryption keys. Unfortunately, the statistics of trustworthy swindlers are rarely good – most users get fooled and do not receive any tools to restore their data even after completing the payment. Moreover, a group of experts tested software provided by cybercriminals and it turned out it has no efficiency in data decryption at all. This is why paying for such services ends up even more pointless. Luckily, there is information that files encrypted by the older version of Ziggy Ransomware can be restored using Emsisoft decryptor. This might not guarantee full decryption, because it seems like some files get damaged during infection. Whatever version you are struggling with, try to use our tutorial for both. At first, we will delete the virus from your PC and only then attempt to decrypt your data.

How Ziggy Ransomware infected your computer

Ziggy Ransomware is known to pounce via poor RDP configuration, however, there are many other channels that could be abused as well. The list of such includes trojans, e-mail spam, fake software cracking tools, botnets, keyloggers, and many more. Cybercriminals tend to exploit users’ inexperience to make them download or interact with malicious content. For example, some extortionists send e-mail messages with malvertising attachments classified as spam. They mark such messages as something legitimate, usually by copying templates of legitimate companies. This technique is used to make a user believe that one is seeing familiar content and correlate no suspicion with it. A range of malicious files may vary from MS Office documents, PDFs, executables, and JavaScript files. Initially, these files are legitimate formats but often reconfigured by cybercriminals to promote malware. If you dare click on any of these attachments from spam messages, chances are you will get infected with ransomware or trojans. To avert this, you should be more attentive and use supplementary software to establish AI protection against potentially dangerous content. You can find more information about it down below.
