removal by Alice Woods - - | Type: Ransomware

Dont_Worry ransomware is a virus that threatens victims by encrypting computer files

Dont_Worry ransomware

Dont_Worry ransomware is a new crypto-virus that has been spotted at the start of April 2018. The malware uses AES/RSA encryption technology. As soon as the virus distributes its malicious payload, it locks up files by using email_ransom-random_ID{16} file extension and drops a ransom note called Dont_Worry.txt. The original executable files are called dwintl_x64.exe and gwintl.exe.

Security experts concluded that the virus belongs to AMBA ransomware family and is targeted towards Russian residents. However, that does not mean that the ransomware cannot strike elsewhere – the internet is worldwide. Therefore, do not let your guard down and, if infected, immediately remove Dont_Worry virus from your machine.

As soon as Dont_Worry virus enters the targeted computer, it immediately performs malicious changes to the system. Malware implements the following steps to strengthen its presence:

  • The version of the virus is easily customizable. Hence, it can be modified for each individual attack, making it harder to extinguish
  • The infection starts with data gathering – both anonymous (software and hardware) and private (email, name, passwords, credentials, etc.). This information is used to bypass security and other software that might prevent the virus from executing its malicious tasks.
  • The virus further changes system's configuration, including a modification to registry entries,[1] boot options, and system parameters.

The mentioned changes allow Dont_Worry ransomware to boot up every time the system is launched. Additionally, these modifications can impact computer performance, including app/system crashes, slow response time, etc.

Dont_Worry can encrypt various files, including .doc, .xlsx, .pdf, .7zip, .jpg and many others. Nevertheless, there are few formats that the data locker skips, including mp3, .mp4, .avi, .exe, .sys and few others. The ransomware appends the email_ransom-random_ID{16} file extension to each of the files. For example, the file called random.doc would be turned into random.doc.wog@onionmail.info-4668ffbf455b468c.

Dont_Worry ransom note states the following:

All your information on this computer has been encrypted.
To decrypt refer to the contacts listed below.

e-mail: wog@onionmail.info
Your code for unlock: 42943870

If you receive an answer that the mailing address does not exist:
1. You are unlucky. The address was blocked.

You will receive all instructions in the reply letter.

As evident, hackers rely on Tor browser anonymous email service to communicate with victims. The size of the ransom is not mentioned in the note, so it seems like hackers inform users in the email. Nevertheless, we advise you not to contact cybercriminals as they are often known to ignore victims, even after all their demands are fulfilled.

Dont_Worry ransomware removal should be your first action. We strongly advise using a powerful anti-malware program, such as Reimage or Malwarebytes Anti Malware. To avoid damage to system files, we do not recommend manual elimination.

You should only proceed with file recovery after full virus elimination. Unfortunately, the only 100% safe way to recover your files is by restoring them from a back-up, stored on a remote server or externally. Alternatively, we offer other recovery methods – please check below.

The way malware is distributed

Most prominent ransomware distribution method is via spam emails. This allows hackers to trick users into opening a malicious file and infecting the system instantaneously. Thus, this method is quick and efficient and widely used. Security experts[2] warn that all the emails coming from unknown sources should be ignored and deleted immediately. Finally, recognizing suspicious emails is critical too so you should check out some examples[3] online.

Other distribution methods of ransomware:

  • Torrent and other peer-to-peer websites;
  • Hacked sites;
  • Exploit kits;
  • Repacked and infected installers;
  • Keygens, etc.

Remove Dont_Worry ransomware from your computer and then attempt file recovery

As we already mentioned, we highly discourage users from attempting manual Dont_Worry removal. Crypto-virus is a complicated code that is embedded deep within system files. Tampering with those files might lead to permanent software damage.

Therefore, we urge you to remove Dont_Worry virus by using security software – Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware. These programs can find and eliminate the threat immediately. Do not attempt file recovery before you fully delete the virus as all the files will get encrypted again.
