How to remove DKOM.doublepulsar

DKOM.doublepulsar – a backdoor that could be used by criminals to install more malware on your system

DKOM.doublepulsar is a computer virus that exploits out of date Windows computers. This backdoor is an advanced trojan that leaves an open gate for a hacker to connect to your PC. It was used for spreading a well-known ransomware WannaCry and accessed PCs through Windows vulnerability. It is very important to follow up with updates to avoid such infections.

DKOM.doublepulsar can collect various data, such as financial and personal info, copy/steal files, etc. It also disables security software that's installed on the computer, thus making the device unprotected. This allows the trojan to upload and install any other malicious software that it's programmed to.

While the infiltration can be entirely prevented by patching Windows with the latest version, the threat is still extremely prevalent in the wild. So if your anti-malware tool flagged it, or you see any suspicious symptoms of the infection (crashing, slower performance,errors) – you came to the right place. In this article, we explain how to remove the malware and repair corrupted system files.

Double Pulsar was developed by the U.S. National Security Agency,^[1] although it was later stolen by cybercriminals who spread the infection worldwide. Malware places a backdoor on the system and exploits a vulnerability inside the Windows kernel known as EternalBlue. In 2017, more than 200,000 computers were infected with the infamous WannaCry ransomware thanks to the usage of this backdoor, resulting in a worldwide cybersecurity disaster.

Trojans like DKOM.doublepulsar, are one of the most hazardous types of malware that are created. They can have an array of built-in functions. To name just a few:

• Copying all files on the infected machine and uploading them to a pre-determined server
• Deleting all data or some system files that would disable the machine
• Downloading and installing additional malicious software
• Displaying an abnormal amount of ads
• Disabling anti-malware software and any security-related services
• Stealing financial info, such as credit card details, logins, passwords, etc.

In the past years, an increasing number of Remote access Trojans (RATs) surfaced, which let the threat actors gain remote control over a victim's computer. That way, the hackers can infect other computers on the network or do whatever they please with the infected one.

Trojans are very hard to detect, as they can be camouflaged as a legitimate application and wait for a trigger to begin what it's developed for. That's why professional anti-malware tools such as SpyHunterCombo Cleaner or MalwarebytesMalwarebytes must be installed on every computer. This type of software is designed to catch malware, just keep its virus databases up to date.

To effectively mitigate the infection and remove DKOM.doublepulsar, users need to disconnect the infected PC from the network, apply the MS17-010 Windows update, reboot the device, and then perform a full system scan with reliable anti-malware. Run the software, perform an entire system scan, and get rid of any suspicious files that the tool flags. 

Malware, especially backdoors, insert themselves in the system registry and other core settings and files. That's why after DKOM.doublepulsar removal, cybersecurity experts from LesVirus.fr^[2] recommend using powerful system repair tools such as the FortectIntego app to delete any new entries and correct any system irregularities.

Sneaky techniques used by trojan developers to distribute them

Trojans are spread using different techniques, but they can't execute themselves. That's why cybercriminals spread them as deceptive ads. For example, while visiting a website, a pop-up abruptly appears stating that you have a virus infection and that you need to scan your system with the advertised tool ASAP. As soon as a user downloads the software and installs it, a trojan plants roots.

Another popular way the trojans are distributed is via file-sharing platforms. Cybercriminals love to exploit the lack of end-to-end security in torrent sharing websites, where they can upload any virus and wait for a soon to be victim to download it. Malicious software is usually named as a game crack for the latest game, unlocked expensive licensed software, and in any other way that would lure someone to download it.

And last but not least – spam emails, yet another way to deliver trojans. Payload files are usually hidden either in email attachments or in hyperlinks to malicious websites. To avoid trojan infections, please refrain from clicking any deceptive ads, don't use file-sharing platforms, and don't open any phony emails and their contents.
