Usr0 Ransomware Removal Guide

Are you responsible for the successful infiltration of Usr0 Ransomware? If you have opened a malicious spam email attachment, you might have executed this threat yourself. The name of this infection derives from the extension that is attached to the files that it encrypts. For example, a simple file called “example.doc” will be renamed to “example.doc.usr0” by this ransomware. Of course, that is not the biggest issue. It is worse that this ransom encrypts your files using a complex algorithm to make them impossible to read. If you want to restore your files, you need a decryption key/private key, but getting it is not that easy. In fact, this key is in the hands of cyber criminals, and you should not expect them to just hand this key over for nothing in return. Obviously, that is the main reason this infection was created altogether. As soon as your files are encrypted, a ransom note will be created, and it will be used to demand payment from you. Learn more about the encryption of your files, decryption keys, and ransom fees, as well as how to delete Usr0 Ransomware by reading this report.

The ransom note of the malicious Usr0 Ransomware is represented via “Важная информация.txt”. This file is created after the encryption of the files is completed, and it is placed on the Desktop, so that you would discover it as soon as possible. Here is the message delivered via this TXT file.

Для того, чтобы узнать, как получить дешифратор, отправте номер {unique ID} в письме на адрес usr0@riseup.net.
Ни в коем случае не используйте сторонние дешифраторы, т.к. файлы будет невожно восстановить.
Если Вы решили попробовать восстановить информацию своими силами, то сделайте сначала резервные копии.

If you follow the instructions within this message, you will send your ID to usr0@riseup.net. The response email will then inform you that you need to pay a ransom. At the time of research, the fee asked in return of a decryption key was 1.24 BTC, which is an extremely large ransom (~47700 RUB, ~680 EUR). Of course, you do not need to pay this ransom, but it does not look like there is another way to get the decryption key. Cyber criminals will not just hand it over after you inform them that you do not have the money. And when it comes to alternatives, our researchers have not found a tool that would be capable of decrypting the files affected by this specific ransomware. Of course, some time might have passed between us posting this report and you reading it. Therefore, you should look into legitimate third-party decryption tools anyway. Just be careful so as not to install malware. Are you scared that your files will be damaged or removed if you use third-party assistance with the decryption of your files? It seems that the intimidating warning in the TXT file is just a tool of intimidation.

The devious Usr0 Ransomware was designed to target personal files, and it can encrypt such file types as AVI, DOC, FLV, MP3, PDF, PNG, PPT, and ZIP. In case you have your documents, archives, photos, videos, and other personal files backed up, you can remove the ransomware. Although your files will remain locked, you will be able to replace them with the copies stored in the backup. Of course, you should do that only after you get rid of the ransomware because it could corrupt the copies as well. Unfortunately, you will not be able to restore your files if you rely on a restore point because this devious threat deletes shadow copies using the command called “vssadmin delete shadows /all /quiet”.

Needless to say, you will have to make a few hard decisions before you remove Usr0 Ransomware from your operating system. Do you follow the demands and take the risk of losing your money and your files, or do you lose your files? Hopefully, you are comfortable with any decision that you make. Right after that, you need to erase the ransomware, and you can download an anti-malware tool to have it eliminated automatically. You should install this software ASAP if you are also dealing with other PC infections, and if you want a reliable tool to keep your operating system protected in the future. If you do not care about any of that, you are left with manual removal. The guide below shows how to locate and erase the malicious ransomware launcher. If the file is not located in the listed directories, we advise running a legitimate malware scanner.
