DeltaSEC virus Removal Guide

What is DeltaSEC ransomware?

DeltaSEC ransomware is malware that relates to Jigsaw family but fails to encrypt any files

DeltaSEC ransomwareDeltaSEC ransomware is malware that fails to encrypt personal files

DeltaSEC ransomware was first spotted by MalwareHunterTeam in mid-February 2019.[1] The malware stems from a well-known Jigsaw virus family and typically encrypts files using AES encryption algorithm, drops a ransom note which is presented in a pop-up window, and demands ransom payment in Bitcoin for the decryption tool. It seems like DeltaSEC virus authors had a similar course of events in mind, however, they failed to correctly write up the base 64 string, which resulted in a failure of the encryption process. However, the infection does perform system modifications, like deleting Shadow Volume copies, modifying Windows Registry and displaying a ransom note. The text in the pop-up window is presented in a typical Jigsaw-like manner, threatening to delete files gradually. Victims are also asked to pay “at least” $60 worth of Bitcoin to the provided wallet. As evident, users should not pay and instead focus on DeltaSEC ransomware removal process.

Name DeltaSEC
Type Ransomware
Family Jigsaw
Related files JigsawRansomware.exe
Discovery date February 2019
Ransom note Pop-up window with no title
File extension N/A
Ransom size $60 in Bitcoin
Decryptable? Yes (does not encrypt any files)
Elimination Use malware removal tools like ReimageIntego or SpyHunter 5Combo Cleaner

DeltaSEC ransomware is most likely delivered with the help of various distribution methods, such as:

  • Spam emails;
  • Fake updates;
  • Exploits;
  • Brute-force attacks;
  • Repacked installers;
  • Malicious sites, etc.

Once inside, DeltaSEC virus performs multiple modifications to the Windows system, such as deletion of volume snapshots, adding/editing registry keys, file opening/copying/writing, module loading, etc. Once these changes are performed, malware spawns a pop-up window which states the following:

.NET Framework Initialization Error

After clicking OK or closing the window, users are greeted with a lengthy and vulgar ransom note from DeltaSEC ransomware authors. In the memo, hackers are trying to mock the victims, implying that they are going to “have a bad time.” Ironically, bad actors are the ones that should be made fun of, as their claims that data is locked are entirely false.

Thus, users should immediately check their data. They will then realize that personal files are not encrypted, and there is no need to contact or paying DeltaSEC ransomware creators.

Nevertheless, there is a possibility that cybercriminals will fix the bug and release the update, which can be applied directly to the infected victims' computers. Therefore, users should immediately remove DeltaSEC ransomware from their devices using a reputable security application that can detect the threat.

For DeltaSEC virus termination, we recommend using ReimageIntego or SpyHunter 5Combo Cleaner, although other security application that can detect the malware can be used as well.[2]

Use these tips to stay away from malware infections

Malware is a multi-million illegal business that is sometimes used by state-governed groups. Other times, hackers simply want to get easy money or seek financial help due to unemployment (or so developers of ARTEMY ransomware claim). Regardless of the reasons, crypto locking malware is beneficial to its creators but can be devastating to users and organizations.

Therefore, it is vital to take care of precautionary measures that could save victims from the permanent data and, in some cases, money loss. Here are some tips from experts[3] that can reduce the infection chance to a minimum:

  • Employ comprehensive security application and keep it up to date;
  • Do not open spam email attachments or click on links unless you are absolutely sure the author is who he/she claims he/she is;
  • Use an ad-blocker, but do not forget to add exclusions to sites you want to support;
  • Patch your system and the installed applications as soon as security updates are released;
  • Be careful when downloading torrent files – scan them using tools like Virus Total;
  • When installing freeware or shareware from the internet, make sure you pick Advanced/Custom installation settings in order to prevent all the optional components from entering your device.

Finally, ensure that you are preparing backups regularly. This can save you from a lot of trouble in case ransomware manages to infect your PC.

Remove DeltaSEC ransomware from your computer to stay safe

Even if the virus does not encrypt data, you should remove DeltaSEC ransomware as soon as possible. For that, we recommend using security applications like ReimageIntego or SpyHunter 5Combo Cleaner, although feel free to use any other program that can detect and eliminate the threat. Be aware that malware might prevent proper operation of security software due to its heavy modification to system files. In such a case, you should access Safe Mode with Networking as explained below.

Once you take care of DeltaSEC ransomware removal, you should be safe to use your computer again. Because the files are not encrypted, you do not need to take any other actions. However, in case the malware becomes properly functional in the future, we are leaving some option file recovery methods in case backups are not available.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove DeltaSEC from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

Currently, the virus does not encrypt files. However, in case it happens in the future, check out alternative data recovery methods in case no backups are available.

If your files are encrypted by DeltaSEC, you can use several methods to restore them:

Make use of Data Recovery Pro

This application is sometimes capable of restoring files if the partition of the deleted data is still available. It sometimes works for ransomware-affected files. Thus, download Data Recovery Pro and use this guide:

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by DeltaSEC ransomware;
  • Restore them.

Windows Previous Versions feature might be able to help you

System Restore feature should have been enabled before ransomware struck for this method to work.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Under certain circumstances, ShadowExplorer can regain all your files

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from DeltaSEC and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
