JERRYRANSOM Virus Files Locked

The Jerryransom virus falls under the ransomware type of malicious agent, that belongs to Chaos ransomware family. Harmful software of such sort encrypts all the data on your computer (images, text files, excel tables, audio files, videos, etc) and adds its extra extension to every file, creating the Read_me.txt files in each directory containing encrypted files.

It is better to prevent, than repair and repent!

Jerryransom virus: what is known so far?

Jerryransom will append a random 4-symbol extension to every file’s title. For example, a file entitled “photo.jpg” will be renamed to “photo.jpg.csri”. Likewise, the Excel file with the name “table.xlsx” will be altered to “table.xlsx.m8ks”, and so forth. There is no strict pattern in how malware picks these extensions.

In every directory containing the encoded files, a Read_me.txt file will appear. It is a ransom money memo. It contains information on 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. You can obtain this decoding tool after contacting jerryjobransom@gmail.com through email. That is basically the scheme of the malefaction.

The Read_me.txt file accompanying the Jerryransom ransomware provides the following dispiriting information:

How did Jerryransom ransomware end up on my PC?

There are plenty of possible ways of ransomware injection.

There are currently three most exploited methods for evil-doers to have ransomware settled in your system. These are email spam, Trojan infiltration and peer-to-peer networks.

• If you access your inbox and see letters that look just like notifications from utility services providers, delivery agencies like FedEx, web-access providers, and whatnot, but whose mailer is unknown to you, be wary of opening those emails. They are most likely to have a ransomware file attached to them. Thus it is even riskier to open any attachments that come with letters like these.
• Another thing the hackers might try is a Trojan horse model. A Trojan is an object that gets into your computer pretending to be something different. For example, you download an installer of some program you want or an update for some software. But what is unboxed turns out to be a harmful agent that encrypts your data. As the update package can have any title and any icon, you have to make sure that you can trust the resource of the stuff you’re downloading. The optimal way is to use the software companies’ official websites.
• As for the peer-to-peer file transfer protocols like torrents 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 directory containing the downloaded objects with the antivirus as soon as the downloading is done.

How to remove ransomware?

It is crucial to note that besides encrypting your files, the Jerryransom virus will probably install Vidar Stealer on your PC to get access to credentials to various accounts (including cryptocurrency wallets). That program can derive your credentials from your browser’s auto-filling data.

Sometimes criminals would unblock some of your files to prove that they do have the decryption tool. As Jerryransom virus is a relatively recent ransomware, security software engineers have not yet found a method to undo its work. However, the anti-ransomware instruments are constantly updated, so the effective countermeasure may soon be available.

Understandably, if the criminals do the job of encrypting victim’s critical data, the desperate person will most likely fulfill their demands. However, paying to criminals does not necessarily mean that you’re getting your blocked information back. It is still dangerous. After getting the money, the racketeers may send a wrong decryption key to the injured party. There were reports of ransomware developers just disappearing after getting the ransom without even writing back.

The best countermeasure to ransomware is to have aan OS restore point or the copies of your critical files in the cloud storage or at least on an external storage. Surely, that might be not enough. Your most crucial thing could be that file you were working on when it all happened. Nevertheless, it is something. It is also advisable to scan your PC for viruses with the antivirus program after the OS is rolled back.

Jerryransom is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. Examples of those are Wing, Fastbackdata, New24, and some others. The two major differences between them and the Jerryransom are the ransom amount and the method of encryption. The rest is the same: files become encoded, their extensions altered, ransom notes appear in every directory containing encoded files.

Some lucky victims were able to decode the arrested files with the help of the free tools provided by anti-malware developers. Sometimes the hackers mistakenly send the decryption key to the victims in the ransom note. Such an extraordinary fail allows the victim to restore the files. But obviously, one should never expect such a chance. Make no mistake, ransomware is a tamperers’ instrument to pull the money out of their victims.

How do I avoid ransomware attack?

Jerryransom ransomware has no superpower, so as any similar malware.

You can armour your PC from ransomware infiltration within three easy steps:

• Ignore any letters from unknown mailboxes with unknown addresses, or with content that has likely no connection to something you are waiting for (can you win in a money prize draw without participating in it?). If the email subject is more or less something you are expecting, scrutinize all elements of the dubious email carefully. A hoax letter will always have a mistake.
• Never use cracked or unknown programs. Trojan viruses are often spreaded as a part of cracked software, most likely as a “patch” which prevents the license check. Understandably, potentially dangerous programs are difficult to tell from reliable software, because trojans may also have the functionality you need. Try searching for information on this software product on the anti-malware forums, but the optimal way is not to use such software.
• And finally, to be sure about the safety of the files you downloaded, use GridinSoft Anti-Malware. This program will be a perfect shield for your personal computer.

Frequently Asked Questions

🤔 How can I open the encrypted files?Can I somehow access them?

Unfortunately, no. You need to decipher the files first. Then you will be able to open them.

🤔 What should I do to make my files accessible as fast as possible?

If the 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. The rest of the methods require patience.

🤔 If GridinSoft deletes the Jerryransom malware, will it also delete my files that were encrypted?

Of course not. Your encrypted files are no threat to your PC.

GridinSoft Anti-Malware only deals with active viruses. The malware that has infiltrated your system is probably still active and launching checks every so often to encode any new files you might create on your computer after the attack. As it has been mentioned above, the Jerryransom virus does not come alone. It installs backdoors and keyloggers that can steal your account credentials and provide hackers with easy access to your system in the future.

🤔 What to do if the Jerryransom malware has blocked my PC and I can’t get the activation code.

In such a case, you need to have a flash memory card with a previously installed Trojan Killer. Use Safe Mode to perform the cleaning. You see, the ransomware runs automatically as the system launches and encrypts any new files created or imported into your machine. To suppress this function – use Safe Mode, which allows only the essential applications to run upon system start. Consider reading our manual on running Windows in Safe Mode.

🤔 What could help the situation right now?

Some of the blocked data can be found elsewhere.

• If you exchanged your critical files through email, you could still download them from your online mailbox.
• You might have shared images or videos with your friends or relatives. Just ask them to give those pictures back to you.
• If you have initially got any of your files from the Internet, you can try downloading them again.
• Your messengers, social networks pages, and cloud storage might have all those files too.
• Maybe you still have the needed files on your old computer, a notebook, mobile, flash memory, etc.

HINT: You can use file recovery programs¹ to retrieve your lost information since ransomware encodes the copies of your files, deleting the authentic ones. In the tutorial below, you can see how to recover your files with PhotoRec, but be advised: you won’t be able to do it before you eradicate the ransomware itself with an anti-malware program.
