The Sepsis virus belongs with the ransomware type of malicious agent. A harmful program of such sort encrypts all the data on your PC (photos, documents, excel tables, music, videos, etc) and adds its extra extension to every file, showing you a pop-up window at the end of encryption.
What is Sepsis virus?
☝️ A strictly accurate designation for the Sepsis is “a ransomware malicious agent”.
The pattern of renaming is this: [contact email].SEPSIS. In the course of encryption, a file entitled, for example, “report.docx” will be renamed to “report.docx.[Sepsis@protonmail.com].SEPSIS”.
After the encryption, you will see the pop-up window. It is a ransom money memo. It contains information about the ways of contacting the racketeers and some other remarks. The ransom note most probably contains a description of how to buy the decryption tool from the tamperers. You can get this decoding tool after contacting Sepsis@protonmail.com by email. That is basically the scheme of the crime.

That is how encrypted “.[contact email].SEPSIS” files look.
How did my computer get infected with Sepsis ransomware?
There is a huge number of possible ways of ransomware injection.
There are currently three most exploited ways for criminals to have ransomware acting in your digital environment. These are email spam, Trojan infiltration and peer-to-peer file transfer.
If you access your mailbox 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, beware of opening those letters. They are very likely to have a malicious item enclosed in them. Therefore, it is even more dangerous to download any attachments that come with emails like these.
Another option for ransom hunters is a Trojan virus scheme1. A Trojan is a program that infiltrates into your machine pretending to be something legal. For example, you download an installer of some program you want or an update for some software. But what is unpacked turns out to be a harmful agent that compromises 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 things you’re downloading. The best thing is to trust the software developers’ official websites.
As for the peer networks like BitTorrent or eMule, the threat is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy resources. Also, it is a good idea to scan the directory containing the downloaded items with the anti-malware utility as soon as the downloading is done.
How to remove the Sepsis virus?
It is crucial to inform you that besides encrypting your data, the Sepsis virus will most likely install the Azorult Spyware on your machine to get access to credentials to different accounts (including cryptocurrency wallets). That program can derive your logins and passwords from your browser’s auto-filling cardfile.
Often racketeers would decode several of your files to prove that they indeed have the decryption program. As Sepsis virus is a relatively new ransomware, anti-malware engineers have not yet found a way to reverse its work. However, the decryption instruments are frequently upgraded, so the effective countermeasure may soon arrive.
Sure thing, if the evildoers do the job of encoding someone’s essential data, the desperate person will most likely 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 receiving the money, the racketeers may deliver a wrong decryption code to the victim. There were reports about racketeers just vanishing after getting the ransom without even writing back.
The optimal countermeasure to 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 storage. Obviously, that might be insufficient. Your most important thing could be that file you were working on when it all started. Nevertheless, it is something. It is also wise to scan your PC for viruses with the anti-malware utility after the OS restoration.
There are other ransomware products, besides Sepsis, that work similarly. Examples of those are Qbaa, Ooii, Fgui, and some others. The two basic differences between them and the Sepsis are the ransom amount and the encoding method. The rest is almost identical: files become encoded, their extensions altered, ransom notes are created in each directory containing encoded files.
Some fortunate people were able to decode the blocked files with the aid of the free tools provided by anti-malware experts. Sometimes the hackers mistakenly send the decoding key to the wronged in the ransom readme. Such an epic fail allows the injured part to restore the files. But naturally, one should never rely on such a chance. Remember, ransomware is a tamperers’ technology to lay their hands on the money of their victims.
How сan I avoid ransomware injection?
Sepsis ransomware has no superpower, so as any similar malware.
You can defend your computer from its infiltration taking several easy steps:
- Never open any letters from unknown mailboxes with strange addresses, or with content that has likely no connection to something you are expecting (how can you win in a lottery without participating in it?). If the email subject is more or less something you are waiting for, check all elements of the dubious letter with caution. A fake letter will surely contain mistakes.
- Never use cracked or untrusted programs. Trojan viruses are often distributed as an element of cracked products, possibly under the guise of “patch” which prevents the license check. Understandably, dubious programs are very hard to distinguish from trustworthy software, because trojans sometimes have the functionality you seek. You can try searching for information about this software product on the anti-malware message boards, but the optimal way is not to use such software.
- And to be sure about the safety of the objects you downloaded, scan them with GridinSoft Anti-Malware. This program will be a powerful shield for your personal computer.

FAQ
🤔 Can I somehow access “.[contact email].SEPSIS” files?
There’s no way to do it, unless the files “.[contact email].SEPSIS” files are decrypted.
🤔 What should I do to make my files accessible as fast as possible?
It’s good if you have fаr-sightedly saved copies of these important files elsewhere. 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.
🤔 You have advised using GridinSoft Anti-Malware to get rid of the Sepsis virus. Does it mean that all my files, currently encrypted, will be removed too?
Absolutely not! Your encrypted files are no threat to your PC.
GridinSoft Anti-Malware only deals with active threats. The virus that has infiltrated your computer is most likely still functional and it scans your system periodically to encode any new files you might create on your PC after the infection. As it has been said above, the Sepsis ransomware comes with the company. It installs backdoors and keyloggers that can steal your account credentials and provide hackers with easy access to your computer in the future.
🤔 What actions should I take if the Sepsis malware has blocked my computer and I can’t get the activation code.
If that happened, you need to prepare a flash memory drive with a pre-installed Trojan Killer. Use Safe Mode to perform the cleaning. The point is that the ransomware runs automatically as the system launches and encrypts any new files created or imported into your PC. To stop this function – use Safe Mode, which allows only the essential applications to run automatically. Consider reading our manual on running Windows in Safe Mode.
🤔 What can I do right now?
Some of the encrypted data can be found elsewhere.
- If you sent or received your critical files via email, you could still download them from your online mail server.
- You may have shared images or videos with your friends or relatives. Simply ask them to send those images back to you.
- If you have initially downloaded any of your files from the Internet, you can try doing it again.
- Your messengers, social networks pages, and cloud drives might have all those files too.
- Maybe you still have the needed files on your old PC, a laptop, mobile, memory stick, etc.
HINT: You can employ file recovery programs4 to get your lost data back since ransomware arrests the copies of your files, deleting the authentic ones. In the tutorial below, you can learn how to use PhotoRec for such a restoration, but be advised: you won’t be able to do it before you remove the virus with an anti-malware program.
Also, you can contact the following governmental fraud and scam sites to report this attack:
- In the United States: On Guard Online;
