The Sulinformatica virus falls under the ransomware type of infection. A harmful program of such sort encrypts all the data on your computer (photos, text files, excel tables, audio files, videos, etc) and appends its specific extension to every file, leaving the Instruction.txt text files in each directory with the encrypted files.

It is better to prevent, than repair and repent!

What is known about the Sulinformatica virus?

Sulinformatica will append its own .aes extension to every file’s title. For example, an image named “photo.jpg” will be renamed to “photo.jpg.aes”. Likewise, the Excel file with the name “table.xlsx” will be renamed to “table.xlsx.aes”, and so forth.

In each folder containing the encrypted files, a Instruction.txt file will be found. It is a ransom money memo. Therein you can find information about the ways of contacting the racketeers and some other information. The ransom note most probably contains instructions on how to purchase the decryption tool from the Sulinformatica developers. You can obtain this decrypting software after contacting SULINFORMATICA@proton.me via email. That is how they do it.

Sulinformatica Summary:

The Instruction.txt document coming in package with the Sulinformatica ransomware provides the following dispiriting information:

How did my machine catch Sulinformatica ransomware?

There are plenty of possible ways of ransomware injection.

Nowadays, there are three most popular ways for evil-doers to have ransomware settled in your system. These are email spam, Trojan introduction and peer networks.

• If you access your mailbox and see letters that look just like notifications from utility services providers, postal agencies like FedEx, web-access providers, and whatnot, but whose “from” field is strange to you, beware of opening those emails. They are most likely to have a ransomware file attached to them. Therefore, it is even riskier to open any attachments that come with letters like these.
• Another option for ransom hunters is a Trojan horse scheme. A Trojan is a program that gets into your machine disguised as something different. For instance, you download an installer of some program you want or an update for some service. But what is unboxed reveals itself a harmful program that compromises your data. Since the update file can have any title and any icon, you’d better be sure that you can trust the source of the stuff you’re downloading. The optimal thing is to use the software companies’ official websites.
• As for the peer-to-peer file transfer protocols like torrents or eMule, the threat is that they are even more trust-based than the rest of the Web. You can never know what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is reasonable to scan the folder containing the downloaded items with the antivirus as soon as the downloading is complete.

How to remove ransomware?

It is important to note that besides encrypting your data, the Sulinformatica virus will probably install Vidar Stealer on your machine to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned spyware can extract your logins and passwords from your browser’s auto-filling data.

Often criminals would unblock several of your files to prove that they really have the decryption program. Since Sulinformatica virus is a relatively recent ransomware, safety measures developers have not yet found a way to undo its work. However, the decryption tools are frequently upgraded, so the effective countermeasure may soon arrive.

Sure thing, if the malefactors succeed in encrypting someone’s critical files, the hopeless person will probably fulfill their demands. However, paying to racketeers does not necessarily mean that you’re getting your data back. It is still risky. After obtaining the money, the racketeers may deliver a wrong decryption key to the victim. There were reports of racketeers simply vanishing after getting the ransom without even bothering to reply.

The optimal safety measure against ransomware is to have a system restore point or the copies of your essential files in the cloud drive or at least on an external disk. Of course, that might be insufficient. The most important thing could be that one you were working upon when it all started. But at least it is something. It is also wise to scan your PC for viruses with the antivirus program after the OS restoration.

There are other ransomware products, besides Sulinformatica, that work similarly. Examples of those are Byee, Ttza, Ttwq, and some others. The two main differences between them and the Sulinformatica are the ransom amount and the method of encryption. The rest is the same: documents become encrypted, their extensions altered, ransom notes appear in every directory containing encrypted files.

Some lucky users were able to decrypt the arrested files with the aid of the free tools provided by anti-ransomware experts. Sometimes the criminals accidentally send the decryption code to the wronged in the ransom note. Such an extraordinary fail allows the user to restore the files. But obviously, one should never expect such a chance. Make no mistake, ransomware is a bandits’ technology to pull the money out of their victims.

How сan I avoid ransomware infection?

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

You can defend your computer from ransomware infiltration within several easy steps:

• Ignore any letters from unknown mailers 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 even taking part in it?). In case the email subject is likely something you are waiting for, check all elements of the questionable email carefully. A fake letter will always have mistakes.
• Avoid using cracked or unknown software. Trojans are often spreaded as a part of cracked software, possibly under the guise of “patch” which prevents the license check. But dubious programs are difficult to tell from trustworthy ones, because trojans may also have the functionality you need. You can try searching for information on this program on the anti-malware forums, but the optimal way is not to use such software.
• And to be sure about the safety of the objects you downloaded, check them with GridinSoft Anti-Malware. This software will be a powerful defense for your system.

FAQ

🤔 How can I open “.aes” files?Is it possible to open“.aes” files?

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

🤔 I really need to decrypt those “.aes” files ASAP. How can I do that?

It’s good if you have fаr-sightedly saved copies of these important files elsewhere. In case you haven’t, there is still a chance that you do have a Restore Point from some time ago to roll back the whole system to the moment when it had no virus yet, but already had your files. There are other ways to beat ransomware, but they take time.

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

Of course not. The encrypted files are not harmful, so they won’t be deleted.

GridinSoft Anti-Malware will remove the threats from your PC. The virus that has infected your device is probably still functional and running scans every so often to encrypt any new files you might create on your computer after the attack. As it has already been said, the Sulinformatica malware does not come alone. It installs backdoors and keyloggers that can steal your account credentials and provide hackers with easy access to your PC after some time.

🤔 What to do if the Sulinformatica virus has blocked my computer and I can’t get the activation code.

In such a case, you need to prepare a flash memory card with a previously installed Trojan Killer. Use Safe Mode to perform the procedure. The point is that the ransomware starts automatically as the system boots and encodes any new files created or brought into your computer. To block this process – use Safe Mode, which allows only the vital programs to run automatically. Consider reading our manual on booting Windows in Safe Mode.

🤔 And what should I do now?

Many of the encrypted files might still be at your disposal

• If you sent or received your critical files through email, you could still download them from your online mailbox.
• You may have shared photographs or videos with your friends or family members. Simply ask them to post those images back to you.
• If you have initially downloaded any of your files from the Internet, you can try downloading them again.
• Your messengers, social media pages, and cloud drives might have all those files too.
• It might be that you still have the needed files on your old PC, a portable device, mobile, flash memory, etc.

HINT: You can employ data recovery programs¹ to retrieve your lost information since ransomware blocks the copies of your files, removing the authentic ones. In the tutorial below, you can learn how to recover your files with PhotoRec, but be advised: you can do it only after you remove the virus with an anti-malware program.
