FIASKO Ransomware (.FIASKO File) — Removal Guide

Fiasko virus: what is known so far?

The renaming will be done by this pattern: id[xxxxxx].[contact-email].FIASKO. In the course of encryption, a file entitled, for instance, “report.docx” will be turned into “report.docx.id[9ECFA84E-3334].[].FIASKO”.

In every folder containing the encrypted files, a info.txt file will be found. 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 buy the decryption tool from the racketeers. You can obtain this decryptor after contacting by email. That is basically the scheme of the felony.

The info.txt document coming in package with the Fiasko malware provides the following dispiriting information:

In the screenshot below, you can see what a folder with files encrypted by the Fiasko looks like. Each filename has the “.FIASKO” extension added to it.

That is how encrypted “.FIASKO” files look.

How did Fiasko ransomware end up on my PC?

Nowadays, there are three most popular methods for criminals to have ransomware planted in your system. These are email spam, Trojan injection and peer-to-peer file transfer.

If you open your inbox and see letters that look like familiar notifications from utility services providers, 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. Thus it is even riskier to open any attachments that come with emails like these.

Another option for ransom hunters is a Trojan virus model³. A Trojan is a program that gets into your PC disguised as something else. For instance, you download an installer for some program you need or an update for some program. But what is unboxed turns out to be a harmful agent that corrupts your data. As the update wizard can have any title and any icon, you have to make sure that you can trust the source of the things you’re downloading. The best way is to use the software companies’ official websites.

As for the peer file transfer protocols like torrent trackers or eMule, the danger 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. So you’d better be using trustworthy websites. Also, it is a good idea to scan the directory containing the downloaded items with the antivirus as soon as the downloading is complete.

How do I get rid of the Fiasko virus?

Sometimes racketeers would decrypt several of your files to prove that they do have the decryption program. As Fiasko virus is a relatively new ransomware, anti-malware developers have not yet found a method to undo its work. However, the decoding instruments are frequently updated, so the effective countermeasure may soon be available.

Understandably, if the hackers succeed in encoding victim’s critical data, the desperate person will probably comply with their demands. Despite that, paying to racketeers does not necessarily mean that you’re getting your blocked information back. It is still dangerous. After getting the ransom, the racketeers may deliver a wrong decryption key to the victim. There were reports about ransomware developers just vanishing after getting the money 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 storage or at least on an external drive. Of course, that might be insufficient. The most important thing could be that file you were working on when it all happened. Nevertheless, it is something. It is also reasonable to scan your PC for viruses with the anti-malware utility after the system is rolled back.

There are other ransomware products, besides Fiasko, that work similarly. For instance, Hkgt, Lltt, Llqq, and some others. The two main differences between them and the Fiasko are the ransom amount and the encoding method. The rest is the same: documents become blocked, their extensions changed, ransom notes are found in each folder containing encrypted files.

Some fortunate people were able to decrypt the arrested files with the help of the free software provided by anti-ransomware developers. Sometimes the hackers mistakenly send the decoding code to the wronged in the ransom readme. Such an extraordinary fail allows the victim to restore the files. But of course, one should never expect such a chance. Make no mistake, ransomware is a criminals’ technology to lay their hands on the money of their victims.

How сan I avoid ransomware infiltration?

You can protect your PC from ransomware injection within three easy steps:

• Ignore any letters from unknown senders with unknown addresses, or with content that has nothing to do with something you are waiting for (how can you win in a lottery without even taking part in it?). If the email subject is more or less something you are waiting for, check all elements of the questionable email carefully. A fake email will always contain a mistake.
• Avoid using cracked or unknown software. Trojans are often distributed as a part of cracked software, most likely as a “patch” to prevent the license check. But potentially dangerous programs are very hard to tell from trustworthy ones, as trojans may also have the functionality you need. Try to find information on this software product on the anti-malware message boards, but the best 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 defense for your system.

There is no better way to recognize, remove and prevent ransomware than to use an anti-malware software from GridinSoft">⁵.

FAQ

🤔 Are the “.FIASKO” files accessible?

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

🤔 The encrypted files are very important to me. How can I decrypt them quickly?

If the “.FIASKO” 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.

🤔 Will GridinSoft Anti-Malware remove all the encrypted files alongside the Fiasko virus?

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

GridinSoft Anti-Malware only deals with actual threats. The malware that has infiltrated your computer is probably still active and launching checks every so often to encrypt any new files you might create on your computer after the attack. As it has been mentioned above, the Fiasko virus comes with the company. It installs backdoors and keyloggers that can take your account passwords by trespass and provide criminals with easy access to your system in the future.

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

In such an unfortunate situation, you need to have a flash memory drive with a pre-installed Trojan Killer. Use Safe Mode to do the cleaning. The point is that the ransomware runs automatically as the system boots and encodes any new files created or brought into your computer. To block this function – use Safe Mode, which allows only the essential applications to run automatically. Consider reading our manual on booting Windows in Safe Mode.

🤔 What can I do right now?

Many of the blocked files might still be within your reach

• If you sent or received your important files through email, you could still download them from your online mailbox.
• You may have shared images or videos with your friends or relatives. Just ask them to post those images back to you.
• If you have initially downloaded any of your files from the Web, you can try doing it again.
• Your messengers, social media pages, and cloud disks might have all those files as well.
• It might be that you still have the needed files on your old computer, a laptop, phone, external storage, etc.

HINT: You can employ file recovery programs⁶ to retrieve your lost information since ransomware encodes 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 ransomware itself with an antivirus program.

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

• In the United States: On Guard Online;
• In Canada: Canadian Anti-Fraud Centre;
• In the United Kingdom: Action Fraud;
• In Australia: SCAMwatch;
• In New Zealand: Consumer Affairs Scams;
• In France: Agence nationale de la sécurité des systèmes d’information;
• In Germany: Bundesamt für Sicherheit in der Informationstechnik;
• In Ireland: An Garda Síochána;

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.
