How to remove Yoshikada Decryptor virus and restore encrypted files

If you fell a victim of a ransomware and have reasons to expect that it’s the Yoshikada Decryptor program – here you'll receive help. We propose plain and safe instructions about Yoshikada Decryptor elimination and practicable methods to recover the encrypted files.

What is Yoshikada Decryptor

 

Ransomware is a worricow of mankind, and every PC operator knows that if you cannot access the data and you see a ransom note – it’s time to be anxious. It’s a true, by the way. An encrypting virus is the most dangerous threat that you can face on the Internet since a common customer has no resources to uninstall it. The single situation when you can overcome an encrypting virus is if you aren't dealing with a real virus, but a screenlocker, that covers your display and attempts to lure your funds. In all other events, if ransomware was developed and tuned in a right way – you should just trust that specialists can beat it. If web-criminals failed somehow, and there are some flaws, that give you an ability to restore information – we will tell to you what to do in this guide.

After encrypting information, virus adds .crypted_yoshikada@cock_lu extension to the files and note with the next requirements:

Your documents, photos, databases and other important files have been encrypted cryptographically strong, without the original key recovery is impossible! To decrypt your files you need to buy the special software - "YOSHIKADA DECRYPTOR" Using another tools could corrupt your files, in case of using third party software we dont give guarantees that full recovery is possible so use it on your own risk. If you want to restore files, write us to the e-mail: This email address is being protected from spambots. You need JavaScript enabled to view it. In subject line write "encryption" and attach your personal ID in body of your message also attach to email 3 crypted files. (files have to be less than 10 MB) It is in your interest to respond as soon as possible to ensure the recovery of your files, because we will not store your decryption keys on our server for a long time.

Ransomware type is not significant, as the AES and RSA methods are too tricky difficult to bruteforce them. It can take thousands of years to carry out all needed calculations on a common machine or, possibly, twenty or thirty years if you can use a mega-efficient gear. We know only two solid ways to beat an encrypting malware: to find vulnerabilities in its code, or break into the Command & Control website, to receive a master key. Some ransomware examples also have a switch that can cease ransomware's activity in full or to scare it off a particular PC. If someone finds such breaker for this ransomware, or create a decryption tool, we'll update this article.

So, what we'd discover if we look inside a Yoshikada Decryptor? It is based on an absolutely legal cryptography algorithm that ciphers all folders on customer’s computer and makes them worthless if you have no key. The key is also encoded with another method. In most cases, scammers prefer RSA and AES algorithms, which have asserted themselves the very complex and fail-safe. These manners and the programs built upon them can be easily found on the Internet, so scammers only have to add techniques of defense, to restrict an inlet to a ransomware, and create the safe update and control scheme. Some encrypting tools can act on their own, and fraudsters get a report of another "client" not before he writes them and forwards the money. The complex viruses are highly active, and transmit files to hundreds addresses, to confuse the malware-fighters and maximize the efforts required to defeat a ransomware.

 

Here you can find some things to inspect, until you can yield and look for a decryption program. As it is written in previous paragraphs, swindlers also fail, and certain specialties of your system may support you to recover data.

 

  • If you don't use the system through an administrator's profile – today’s your happy day. The thing is that the operating system replicates all files before their elimination or modification. These copies are called SVC, and Yoshikada Decryptor has the methods to delete them. If you are using the regular profile – the system asks for a authorization at the very moment Yoshikada Decryptor starts to delete SVC. If you've seen such request and ignored it – your copies are safe, and might be used to restore the files.
  • If you've made a backup, stored on the external media – just remove a ransomware and use it. Ensure that Yoshikada Decryptor is deleted in full, since if it isn't – all data will be encrypted instantly, including those that were saved on a flash disc.

 

If all of written above advice didn't help and there is no way to get back lost data – you need to delete Yoshikada Decryptor from your device and wait until a decryption tool will be published.

How to remove Yoshikada Decryptor

Unfortunately, you can't fully escape an installation of an AV-tool. Yoshikada Decryptor is very tricky and you could pass some remains and then regret it (for example, when you attach a flash drive with your backups to a not-fully-purged computer). It knows how to hide pretty good, so you just can't eliminate it fully in manual mode. Knowing this, we have made a solid removal guide that will suit all your needs. It has several manual stages and one extra anti-viral program stage.

How to restore files

If you cleared your PC of the ransomware, you should try to do some data recovery. As you know now, if you logged in from an admin account and you granted the virus an access to the computer – there is no trick to get back your information except for the backups. If you that didn't happen – you still have some chances, but it will require specific recovery software. The most effective ones of them are Recuva or ShadowExplorer tools. They're easy to get on the registered websites of their creators, with close instructions.

  • Click Start
  • Click Control Panel

Decrypt files. Step 1

 

  • Click System and Security

Decrypt files. Step 2

 

  • Select Backup and Restore

Decrypt files. Step 3
