ASISTCHINADECRYPTION Ransomware — How to remove virus?

The Asistchinadecryption virus falls under the Zeppelin ransomware family. Malware of this type encrypts all the data on your PC (images, text files, excel tables, music, videos, etc) and adds its own extension to every file, creating the !!! ALL YOUR FILES ARE ENCRYPTED !!!.TXT text files in every folder which contains the encrypted files.

Asistchinadecryption virus: what is known so far?

☝️ A strictly correct description for the Asistchinadecryption would be “a Zeppelin family ransomware malicious agent”.

The scheme of renaming is the following: asistchinadecryption.[victim\’s_ID]. After the encryption, a file named, for instance, “report.docx” will be turned into “report.docx.asistchinadecryption.ID103HBFU138”.

In each folder that contains the encrypted files, a !!! ALL YOUR FILES ARE ENCRYPTED !!!.TXT text document will appear. It is a ransom money note. Therein you can find information about the ways of paying the ransom and some other remarks. The ransom note usually contains a description of how to purchase the decryption tool from the tamperers. That is it.

How did Asistchinadecryption ransomware end up on my PC?

There are many possible ways of ransomware infiltration.

Nowadays, there are three most popular ways for evil-doers to have the Asistchinadecryption virus settled in your digital environment. These are email spam, Trojan infiltration and peer networks.

If you open your inbox and see emails that look like familiar notifications from utility services companies, postal agencies like FedEx, Internet providers, and whatnot, but whose addresser is strange to you, be wary of opening those letters. They are very likely to have a ransomware file enclosed in them. So it is even riskier to download any attachments that come with letters like these.

As for the peer networks like torrent trackers or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. So you’d better be using trustworthy resources. Also, it is reasonable to scan the folder containing the downloaded objects with the anti-malware utility as soon as the downloading is complete.

How do I get rid of the Asistchinadecryption virus?

It is crucial to note that besides encrypting your data, the Asistchinadecryption virus will most likely install the Azorult Spyware on your PC to get access to credentials to different accounts (including cryptocurrency wallets). That spyware3 can extract your credentials from your browser’s auto-filling data.

Often tamperers would decode few of your files so you know that they indeed have the decryption program. As Asistchinadecryption virus is a relatively new ransomware, anti-malware engineers have not yet found a way to reverse its work. However, the decryption instruments are constantly updated, so the solution may soon arrive.

Understandably, if the evildoers succeed in encrypting victim’s critical data, the desperate person will most likely fulfill their demands. Nevertheless, paying to criminals gives no guarantee that you’re getting your data back. It is still dangerous. After getting the money, the racketeers may send a wrong decryption key to the injured party. There were reports about racketeers simply vanishing after getting the money without even bothering to reply.

The optimal countermeasure to ransomware is to have a system restore point or the copies of your critical files in the cloud drive or at least on an external storage. Of course, that might be insufficient. Your most crucial thing could be that file you were working upon when it all started. Nevertheless, it is something. It is also advisable to scan your PC for viruses with the anti-malware utility after the system is rolled back.

There are other ransomware products, besides Asistchinadecryption, that work similarly. Examples of those are Dehd, Zaqi, Sbpg, and some others. The two major differences between them and the Asistchinadecryption are the ransom amount and the method of encryption. The rest is almost identical: documents become inaccessible, their extensions altered, ransom notes emerge in every directory containing encoded files.

Some fortunate people were able to decrypt the blocked files with the help of the free software provided by anti-malware specialists. Sometimes the racketeers mistakenly send the decoding key to the wronged in the ransom readme. Such an extraordinary fail allows the injured part to restore the files. But obviously, one should never rely on such a chance. Make no mistake, ransomware is a bandits’ tool to pull the money out of their victims.

How сan I avert ransomware attack?

Asistchinadecryption ransomware doesn’t have a superpower, so as any similar malware.

You can armour your PC from its injection taking several easy steps:

  • Ignore any letters from unknown senders with strange addresses, or with content that has nothing to do with something you are expecting (how can you win in a money prize draw without participating in it?). In case the email subject is likely something you are waiting for, check all elements of the questionable letter with caution. A fake letter will always contain a mistake.
  • Avoid using cracked or unknown programs. Trojan viruses are often shared as an element of cracked products, most likely as a “patch” to prevent the license check. But untrusted programs are very hard to distinguish from reliable software, as trojans may also have the functionality you need. Try searching for information on this software product on the anti-malware forums, but the optimal solution is not to use such programs at all.

Frequently Asked Questions

🤔 Are the “.asistchinadecryption.[victim\’s_ID]” files accessible?

Unfortunately, no. You need to decipher the “.asistchinadecryption.[victim\’s_ID]” files first. Then you will be able to open them.

🤔 I really need to decrypt those “.asistchinadecryption.[victim\’s_ID]” files ASAP. How can I do that?

If the “.asistchinadecryption.[victim\’s_ID]” files contain some really important information, then you probably have them backed up. Otherwise, you might try to employ System Restore. The only question is whether you have saved any Restore Points that would be helpful now. All other solutions require time.

🤔 What should I do if the Asistchinadecryption ransomware has blocked my computer and I can’t get the activation code.

🤔 And what should I do now?

Many of the blocked files might still be at your disposal

  • If you exchanged your critical files through email, you could still download them from your online mail server.
  • You might have shared photographs or videos with your friends or family members. Just ask them to give those images back to you.
  • If you have initially got any of your files from the Web, you can try doing it again.
  • Your messengers, social networks pages, and cloud drives might have all those files as well.
  • Maybe you still have the needed files on your old computer, a notebook, cellphone, flash memory, etc.

USEFUL TIP: You can use data recovery programs6 to retrieve your lost information since ransomware blocks the copies of your files, deleting the authentic ones. In the video below, you can learn how to use PhotoRec for such a restoration, but remember: you won’t be able to do it before you kill the ransomware itself with an antivirus program.

Also, you can contact the following governmental fraud and scam sites to report this attack:

To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
