ANONTSUGUMI Ransomware πŸ” (.ANONTSUGUMI File) β€” Removal Guide

Written by Brendan Smith

The Anontsugumi virus falls within the ransomware type of malicious agent. A harmful program of such sort encrypts all user’s data on the PC (photos, documents, excel tables, audio files, videos, etc) and adds its own extension to every file, creating the README.txt text files in each folder which contains the encrypted files.

Anontsugumi virus: what is known so far?

Anontsugumi appends its own .anontsugumi extension to every file’s name. For instance, a file named “photo.jpg” will be turned into “photo.jpg.anontsugumi”. Likewise, the Excel sheet with the name “table.xlsx” will become “table.xlsx.anontsugumi”, and so on.

In every folder that contains the encrypted files, a README.txt file will be created. 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 instructions on how to buy the decryption tool from the racketeers. You can get this decryptor after contacting Telegram contact menitoned in the note. That is pretty much the scheme of the crime.

How did my computer get infected with Anontsugumi ransomware?

There are many possible ways of ransomware infiltration.

Nowadays, there are three most exploited methods for tamperers to have ransomware planted in your digital environment. These are email spam, Trojan injection and peer file transfer.

  • If you access your inbox and see letters that look just like notifications from utility services companies, postal agencies like FedEx, Internet providers, and whatnot, but whose “from” field is strange to you, be wary of opening those letters. They are very likely to have a viral item attached to them. So it is even more dangerous to open any attachments that come with letters like these.
  • Another thing the hackers might try is a Trojan horse scheme. A Trojan is an object that infiltrates into your computer pretending to be something legal. Imagine, you download an installer of some program you need or an update for some software. But what is unboxed reveals itself a harmful program that compromises your data. Since the installation wizard can have any name and any icon, you have to make sure that you can trust the source of the files you’re downloading. The optimal thing is to trust the software companies’ official websites.
  • As for the peer-to-peer file transfer protocols 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. Our suggestion is that you use trustworthy resources. Also, it is a good idea to scan the folder containing the downloaded files with the anti-malware utility as soon as the downloading is done.

How do I get rid of ransomware?

It is crucial to note that besides encrypting your files, the Anontsugumi virus will probably install Vidar Stealer on your computer to seize your credentials to various accounts (including cryptocurrency wallets). The mentioned spyware can extract your logins and passwords from your browser’s auto-filling cardfile.

Sometimes racketeers would decode some of your files to prove that they really have the decryption program. As Anontsugumi virus is a relatively recent ransomware, anti-malware designers have not yet found a method to reverse its work. However, the anti-ransomware tools are constantly updated, so the effective countermeasure may soon be available.

Understandably, if the malefactors do the job of encrypting victim’s essential data, the hopeless person will probably comply with their demands. Despite that, paying to racketeers gives no guarantee that you’re getting your files back. It is still dangerous. After receiving the ransom, the racketeers may send a wrong decryption key to the victim. There were reports of hackers simply vanishing after getting the ransom without even bothering to reply.

The optimal countermeasure to ransomware is to have aan OS restore point or the copies of your critical files in the cloud drive or at least on an external disk. Obviously, that might be insufficient. The most crucial thing could be that one you were working on when it all went down. But at least it is something. It is also reasonable to scan your PC for viruses with the antivirus program after the system is rolled back.

There are other ransomware products, besides Anontsugumi, that work similarly. For instance, 6y8dghklp, Hgew, Hgfu, and some others. The two major differences between them and the Anontsugumi are the ransom amount and the encoding method. The rest is almost identical: documents become encrypted, their extensions altered, ransom notes appear in every folder containing encrypted files.

Some fortunate victims were able to decode the arrested files with the aid of the free software provided by anti-ransomware experts. Sometimes the criminals mistakenly send the decoding code to the wronged in the ransom readme. Such an epic fail allows the user to restore the files. But of course, one should never expect such a chance. Make no mistake, ransomware is a criminals’ tool to pull the money out of their victims.

How to avoid ransomware attack?

Anontsugumi ransomware doesn’t have a endless power, neither does any similar malware.

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

  • Ignore any emails from unknown mailboxes with unknown addresses, or with content that has nothing to do with something you are waiting for (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 suspicious email carefully. A hoax letter will surely contain mistakes.
  • Never use cracked or untrusted programs. Trojan viruses are often spreaded as a part of cracked products, most likely under the guise of β€œpatch” which prevents the license check. But dubious programs are difficult to distinguish from reliable ones, 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 software.
  • And to be sure about the safety of the files you downloaded, scan them with GridinSoft Anti-Malware. This software will be a perfect armor for your personal computer.

FAQ

πŸ€” How can I open “.anontsugumi” files?Is it possible to openβ€œ.anontsugumi” files?

Negative. That is why ransomware is so frustrating. Until you decode the “.anontsugumi” files you will not be able to access them.

πŸ€” I really need to decrypt those β€œ.anontsugumi” files ASAP. How can I do that?

Hopefully, you have made a copy of those important files. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. There are other ways to beat ransomware, but they take time.

πŸ€” If GridinSoft deletes the Anontsugumi malware, will it also delete my files that were encrypted?

No way! The encrypted files are not harmful, so they won’t be deleted.

GridinSoft Anti-Malware will remove active infections from your system. The ransomware that has attacked your PC is probably still active and it scans your system every so often to arrest any new files you might create on your computer after the infection. As it has been mentioned above, the Anontsugumi ransomware does not come alone. It installs backdoors and keyloggers that can steal your account credentials and provide malefactors with easy access to your computer in the future.

πŸ€” What actions should I take if the Anontsugumi virus has blocked my PC and I can’t get the activation code.

In such an unfortunate situation, you need to have a flash memory drive with a previously installed Trojan Killer. Use Safe Mode to perform the cleaning. The point is that the ransomware runs automatically as the system boots and encodes any new files created or imported into your computer. To suppress this process – use Safe Mode, which allows only the vital applications to run upon system start. Consider reading our manual on running Windows in Safe Mode.

πŸ€” What could help the situation right now?

Many of the blocked files might still be at your disposal

  • If you exchanged your critical files via email, you could still download them from your online mailbox.
  • You may have shared images or videos with your friends or family members. Just ask them to send those pictures 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 disks might have all those files too.
  • Maybe you still have the needed files on your old computer, a portable device, mobile, flash memory, etc.

USEFUL TIP: You can employ file recovery utilities1 to retrieve your lost information since ransomware encrypts the copies of your files, removing the authentic ones. In the tutorial below, you can learn how to use PhotoRec for such a restoration, but be advised: you can do it only after you remove the virus with an anti-malware program.
