{[email protected]}.2k19sys Virus - How to remove

2k19sys is a file-encrypting virus that affects Windows computers. This type of virus encrypts files with genuinely strong encryption and demands money for allowing the victim to recover their files.

2k19sys is one of many new and active ransomware viruses that are threatening the security of individuals and businesses. It preys on systems protected with weak passwords, or vulnerable to deceptive e-mails.

Whether files can be recovered or not depends on how well the victim of 2k19sys was prepared before the infection, but even without backups, there is some hope of recovering a few files.

The features of 2k19sys

The 2k19sys-encrypted files are renamed by adding a suffix to the file name. The suffix includes the unique id of the victim, the e-mail address of the extortionists, and “2k19sys”.

The e-mail address [email protected] and the victim’s id can be found in a ransom note, as well as a window that’s opened by the 2k19sys virus after encryption has finished (so, if you don’t see it, it’s possible that your version of 2k19sys experienced some technical difficulties — maybe it did not encrypt everything?).

The 2k19sys ransom note is named =###_INFO_you_FILE_###=-.txt. It’s short and to-the-point:

All your files have been blocked for more information, please contact us by e-mail.
E-Mail: [email protected]  and [email protected]
The faster you contact us the faster we can help you.

2k19sys also shows a ransom message that looks a lot like the ones used by Dharma or Paradise cryptoviruses. In fact, the text is almost the same as NWA or Dharma-Btc.

  • Do not try to decrypt your data using third party software, it may cause permanent data loss
  • You are guaranteed to get the decryptor after payment
  • Do not attempt to use the antivirus or uninstall the program
  • This will lead to your data loss and unrecoverable
  • Decoders of other users is not suitable to decrypt your files – encryption key is unique

How is 2k19sys distributed?

2k19sys and viruses like it use a few different distribution methods.

First, breaking in through RDP. Cybercriminals can brute-force the login credentials if they’re weak, or they can use phishing to steal them. After getting access to the computers, they can do what they want, including installing 2k19sys, stealing information, installing Trojans. This sort of manual attack that requires the criminals to be involved is employed against small and medium-sized businesses which are expected to have enough funds to pay the ransom, but not enough to take revenge on the extortionists behind 2k19sys.

2k19sys can also come in spam e-mails with either infected attachments, or infected links. These e-mails can be sent out in bulk and affect both businesses, and individuals. 2k19sys could be hiding in an innocent-looking document, or an archive. This strategy of distributing ransomware requires the victim to open or run the infected file. To achieve this, the e-mails try to make recipients too anxious, excited, scared to ignore the spam e-mail.

It’s important to find out how specifically your system was infected, plug those security holes, and protect yourself from ransomware.

Can the files be recovered?

Update: there now is a free decrypter, it was released by Emsisoft, here is the link.

The files can be recovered in theory. There is decryption software, but it is useless without the decryption keys. Those keys are only known to the criminals behind 2k19sys. But if 2k19sys is anything like other ransomware, the decryption keys are going to cost thousands of dollars. If the encryption was implemented poorly or the keys were leaked, it’s possible for a free decryptor to be developed. Sometimes third parties offer paid decryption, but they don’t usually have any special tools and sometimes just contact the criminals.

Other ways of restoring the 2k19sys-encrypted files include copying them from backups. If the backups were kept up-to-date and stored disconnected from the infected computers, they should be used to restore the files — just remove any malware before that.

There is also a possibility that 2k19sys did not delete Windows Shadow Volume Copies, or that some files can be returned using data recovery software. Look at the guide below for a bit more details.

If you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. They store copies of your files that point of time when the system restore snapshot was created. Usually 2k19sys - [email protected] Virus tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so. Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer. a) Native Windows Previous Versions Right-click on an encrypted file and select PropertiesPrevious versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.

There are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:
  • We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
  • Download a data recovery program.
  • Install and scan for recently deleted files. Data Recovery Pro
Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
