DotZeroCMD Virus – Distribution Ways

The DotZeroCMD virus is being distributed by an unknown hacker individual or a criminal collective against computer users worldwide. According to the released reports it is set primarily against English-speaking users even though it is distributed all across the globe. Unlike most other threats it appears to be made specifically for 64-bit versions of Microsoft Windows.

It uses the same delivery tactics as other malware. One of the main virus infection methods is to send out spam email messages that contain social engineering tricks. The criminals behind the DotZeroCMD virus coerce the targets into interacting with the malware element. They may opt to send out the files directly as file attachments or hyperlinks that are placed in the body contents. The usual way is to hijack well known Internet services and their contents. The messages are modeled after the sites themselves which is a common blackmail tactic.

In connection with the email messages the hackers behind the DotZeroCMD virus may use payload delivery attacks. Two popular approaches are the following:

  • Documents — The DotZeroCMD code can be embedded in files of different types: rich text documents ,spreadseheets or presentations. When they are opened by the victims a notification prompt will be spawned that asks them to enable the built-in scripts (macros). This triggers the virus infection.
  • Bundle Installers — The DotZeroCMD virus can be integrated in software installers that are usually hijacked copies of famous applications. The hackers usually target well-known applications such as creative suites, system utilities and computer games. They are spread both using emails and hacker-controlled sites.

In addition the malware files associated with the DotZeroCMD can be distributed using malware sites. They may use the design template of famous sites in order to manipulate the users into thinking that they are downloadinf files from a safe location.

The other method would be to use browser hijackers. They represent malware plugins that are made compatible with the most popular apps: Mozilla Firefox, Google Chrome, Safari, Internet Explorer, Opera and Microsoft Edge. Once they are installed onto the victim systems the dangerous component triggers changes in the relevant applications by redirecting the users to a hacker-controlled page. The modified values are the default home page, new tabs page and search engine. The next step is to deploy the malware code onto the victims.

DotZeroCMD Virus – In-Depth Analysis

The security reports show that the DotZeroCMD virus does not belong to any one of the famous malware families. At the same time there is no information on the individual or criminal collective behind it. The main malware engine can be updated with different instructions depending on the current attack campaign.

It is a complex RaaS (ransomware as a service) which means that its code can be made available to a lot of hackers. Depending on the exact criminal campaign it can start different modules. One of the first ones launched after the virus infection has been initiated is the information gathering one. It can harvest sensitive data that is categorized into two main types:

  • Anonymous Metrics — They represent data that is used primarily to judge how effective the campaign is. It is composed of data about the hardware components and certain operating system values.
  • Private Data — The harvested information is composed of strings that can directly identify the victims. This includes their name, phone number, interests, location, preferences, passwords and account credentials.

If the malware engine includes a stealth protection module it can be used to identify applications and services that can interfere with DotZeroCMD’s execution. This includes anti-virus software, debug environments or virtual machine hosts. When such are found their real-time engines can be bypassed or the relevant software can be entirely removed. In certain cases if the virus is not able to do this then it can remove itself to avoid detection.

Other malware activity can include system changes. For instance the DotZeroCMD virus can modify entries in the Windows Registry. If the virus modifies any existing Windows-related values then this can cause substantial performance issues. Modifications to applications or services can render them non-working.

The malware engine can also be used to modify the boot options, such steps usually remove the possibility to log into the startup recovery menu. To make recovery more difficult the criminals behind the DotZeroCMD virus can opt to delete the identified Shadow Volume Copies of the identified sensitive data. This makes it very hard to recover the affected files unless a professional-grade solution is used. Refer to our instructions for more information.

A network connection can be initiated with the criminal servers. In this case the virus acts similar to a Trojan instance — the operators can spy on the victims in real time and overtake control of them. This module can also be used to deploy additional threats.

DotZeroCMD Virus – Encryption Process

Once all components have executed correctly the ransomware engine is started. It uses a strong encryption cipher in order to affect as many user data as possible. An example list of target file types may include the following:

  • Archives
  • Backups
  • Music
  • Videos
  • Images
  • Databases

Note: Some of the malware strains have been found to merely imitate encryption. They may rename the files however encryption is not applied.

It then spawns a lockscreen instance that is designed in a similar way to Petya which reads the following:

What is DotZeroCMD Ransomware?

DotZeroCMD is a ransomware infection - the malicious software that enters your computer silently and blocks either access to the computer itself or encrypt your files. 

Many ransomware viruses use sophisticated encryption algorithms to make your files inaccessible. The goal of ransomware infections is to demand that you pay a ransom payment to get access to your files back.

Can DotZeroCMD Ransomware Cayse Damage?

Yes, ransomware can damage your computer. Ransomware is a malicious software that is designed to block access to your computer or files until a ransom is paid.

Ransomware can also damage your system, corrupt data and delete files, resulting in the permanent loss of important files.

Should I Ignore Viruses, Like DotZeroCMD?

No, you should never ignore ransomware. It can encrypt your data and block access to your computer, making it impossible to access your files until you pay a ransom.

Ignoring ransomware could lead to the permanent loss of your data, as well as the potential for the ransomware to spread to other computers on your network. Additionally, paying the ransom does not guarantee that your data will be recovered.

How Does DotZeroCMD Infect?

Via several ways.DotZeroCMD Ransomware infects computers by being sent via phishing emails, containing virus attachment

This attachment is usually masked as an important document, like an invoice, bank document or even a plane ticket and it looks very convincing to users. 

After you download and execute this attachment, a drive-by download occurs and your computer is infected with the ransomware virus.

Another way you may become a victim of DotZeroCMD is if you download a fake installer, crack or patch from a low reputation website or if you click on a virus link. Many users report getting a ransomware infection by downloading torrents.

How to Open .DotZeroCMD files?

You can't. At this point, the .DotZeroCMD files are encrypted. You can only open them once they are decrypted using a specific decryptionkey for the particular algorithm.

What to Do If a Decryptor Does Not Work?

Do not panic, and backup the files. If a decryptor did not decrypt your .DotZeroCMD files successfully, then do not despair, because this virus is still new.

Can I Restore ".DotZeroCMD" Files?

Yes, sometimes files can be restored. We have suggested several file recovery methods that could work if you want to restore .DotZeroCMD files. 

These methods are in no way 100% guaranteed that you will be able to get your files back. But if you have a backup, your chances of success are much greater.

How To Get Rid of DotZeroCMD Virus?

The safest way and the most efficient one for the removal of this ransomware infection is the use a professional anti-malware program.

It will scan for and locate DotZeroCMD ransomware and then remove it without causing any additional harm to your important .DotZeroCMD files.

What to Do If I Cant Get The Files Back?

There is still a lot you can do. If none of the above methods seem to work for you, then try these methods:

  • Try to find a safe computer from where you can can login on your own line accounts like One Drive, iDrive, Google Drive and so on.

  • Try to contact your friends, relatives and other people so that they can check if they have some of your important photos or documents just in case you sent them.
  • Also, check if some of the files that were encrypted can be re-downloaded from the web.
  • Another clever way is to find another old computer, a flash drive or even a CD or a DVD where you may have saved your older documents. You might be surprised what will turn up.
  • You can also go to your email account to check if you can send any attachments to other people. Usually what is sent the email is saved on your account and you can re-download it. But most importantly, make sure that this is done from a safe computer and make sure to remove the virus first.
