What is Dulgtv ransomware?

Dulgtv ransomware – a cryptovirus that appends .dulgtv extension to all non-system files on an infected computer

Dulgtv ransomwareDulgtv ransomware - another member of Xorist malware family

Dulgtv ransomware is a computer virus that encrypts all personal data on a targeted machine, preventing access to any files, and then demands a ransom for a decryption tool. This cryptovirus got its name like most of the ransomware – from the extension that it appends to all non-system files – .dulgtv.

Dulgtv virus derives from a family of the Xorist ransomware, that's been intimidating everyday computer users since 2016. Cryptoviruses from this family uses either XOR[1] or TEA cryptography to lock all personal user files, like photos, videos, documents, archives, databases, and so on.

As soon as .dulgtv file virus gets access to a computer, the infection is started immediately. After it encrypts and renames all files, ransom notes named HOW TO RESTORE YOUR FILES.TXT are created in all commonly-used folders. This note's purpose is to inform the victims of what has happened and what they should do next to regain access to their files.

name Dulgtv ransomware, .dulgtv file virus
type Ransomware
Family Xorist ransomware
Appended file extension All non-system files are appended with a .dulgtv extension
Ransom note HOW TO RESTORE YOUR FILES.TXT is generated in all affected folders on the victim's computer
Criminal contact details Two emails are provided to contact the criminals – cryptolifeguard@tutanota.com and cryptolifeguard@cock.li
Malware removal All malware, including ransomware, should be removed immediately with the help of professional, trustworthy anti-malware software
System Fix When the victims eliminate Dulgtv ransomware, system repair tools like the ReimageIntego app should be used to revert any changes that the cryptovirus might have caused to system settings and system files

In the ransom note, the creators of Dulgtv ransomware first state that all victim files were encrypted and that only they can unlock them. They then provide two emails for communication purposes – cryptolifeguard@tutanota.com and cryptolifeguard@cock.li. Crooks claim that they would “always” reply within the first 24 hours and that victims should check their spam folder if the reply does not arrive in time.

Then the usual threat as found in most of the ransomware ransom notes is declared – not to try and rename or edit the encrypted data because that could lead to permanent file loss. To prove that the developers of Dulgtv virus really possess the required decryption tool, they offer a free decryption of 3 files.

Ransomware note of Dulgtv ransomware isn't informative as the ones in Lisp or Weui, where the ransom amount is specified, sometimes even the crypto wallet address is given to forward the money, and a unique user ID is appointed so it would be easier for the cybercriminals to identify their victims.

Dulgtv ransomware virusDulgtv ransomware is a type of virus that encrypts all personal data on the device and then asks for a ransom to decrypt it

Victims should never trust the cybercriminals and remove Dulgtv ransomware instead. Manual removal of such cryptovirus could be a lengthy and difficult process even for tech-savvy people, so we suggest leaving this work to professional anti-malware software like SpyHunter 5Combo Cleaner or Malwarebytes.

After Dulgtv ransomware removal, experts [2] recommend performing a full system scan with a system repair tool like the ReimageIntego to restore any changes that the cryptovirus has done to the registry of the computer, and other core files and settings.

Developers of Dulgtv ransomware enclose this message with the ransom notes (HOW TO RESTORE YOUR FILES.TXT):

Hello! All your files are encrypted and only I can decrypt them.
Contact me:

cryptolifeguard@tutanota.com or cryptolifeguard@cock.li

Write me if you want to return your files – I can do it very quickly!
The header of letter must contain extension of encrypted files.
I'm always reply within 24 hours. If not – check spam folder, resend your letter or try send letter from another email service (like tutanota.com).

Attention!
Do not rename or edit encrypted files: you may have permanent data loss.

To prove that I can recover your files, I am ready to decrypt any three files (less than 1Mb) for free (except databases, Excel and backups)

Most common spreading techniques of the ransomware

In this day and age, the internet is crawling with all kinds of malware, just sitting there quietly and waiting for unaware computer users to take a wrong turn and get their devices infected. There are various techniques the cybercriminals use to infect computers, but ransomware is distributed mainly in two ways – spam emails and torrent websites.

Hackers send out thousands of spam emails to unsuspecting users each day. These emails contain one of two (or both) – hyperlinks to malicious websites where the ransomware is downloaded onto a computer automatically, or infected attachments that once downloaded start an infection immediately.

Downloading torrents from torrent websites is another sure way to get your computer infected. Cybercriminals disguise their creations as popular software/game cracks,[3] unlocked licensed software, game cheat codes, or any other thing that will lure the soon to be victim to download it.

Dulgtv virus detectionDulgtv virus can be stopped before it manages to encrypt files as long as a powerful security tool is operational

Users should be aware of these threats and refrain from using torrent websites, never open any spam emails and hyperlinks in them, scan every email attachment with powerful anti-malware software before downloading them.

Removing Dulgtv ransomware from infected computers with the help of anti-malware software

Victims of Dulgtv ransomware virus attacks should never trust the cybercriminals because there's absolutely no guarantee that after the ransom payment is made they will ever get the promised decryption tools. There might be other ways to restore the encrypted data and the cyber attacks victims should research them or try our suggestions at the bottom of this article.

Victims should trust professional anti-virus applications for the virus elimination. We recommend using anti-malware software like SpyHunter 5Combo Cleaner or Malwarebytes to remove Dulgtv ransomware and all its components from the infected machines automatically.

When Dulgtv ransomware removal is completed, it is highly recommended to scan the virus-free machines with the ReimageIntego tool to undo any changes that the malware could have done to the computer's system files and its settings. Only after this, the users are safe to restore their data from backups.

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.
