DoppelPaymer Files Virus April LA Attacks

A large ransomware attack carrying the DoppelPaymer as the primary weapon of choice was used to successfully infiltrate network systems in the LA County. It appears that the hackers have been able to gain access to sensitive data which were stolen and the ones which are left in the computers are encrypted with a powerful cipher. The information was then published on a hacker site which reports what kind of data has been hijacked.

Among the posted information there are archived data which contains financial records, accounting data and other sensitive data. One of the most notable hacks were the ones related to the City of Torrance in CA.

The campaign was initially detected in March this year. One of the groups associated with the DoppelPaymer ransomware has been able to break into the municipality’s computers and erased the made backups. After this action was done the encryption process was started against 150 servers and 400 workstations. More than 200 GB are claimed to have been stolen by the hackers.

DoppelPaymer Files Virus April 2020 Update

A recent development surrounding the DoppelPaymer ransomware is the successful attack against Kimchuk, a company specializing in the development of medical and electronics supplies. The dangerous threat is specialized in building devices for telecom providers, energy grids, healthcare providers and even the military. Kimchuk is known for producing nuclear modules for the Navy, work that requires security clearance.

According to the available information the attacks happened in March 2020 and the company has refused to pay the hackers and thus data has started to be published on criminal communities. Some of the leaked information includes payroll records, purchase orders and trade data. Regarding the data none of the files contain classified information. However some of them included details about orders for nuclear divisions of the company’s clients.

DoppelPaymer Ransomware Virus Distribution Details

Information about the DoppelPaymer files virus is released constantly. During the ongoing attacks various campaigns and variables have been detected. Security experts have ever since contradicted the statement that the ransomware infects through the BlueKeep bug. This is a bug which affects the Microsoft Windows operating system and specifically the remote desktop protocol. It became known to the general purpose following massive vulnerability testing. Ever since its discovery Microsoft released emergency security patches for all users. The virus detection of the DoppelPaymer files virus shows that the hackers are mainly using stolen passwords from the network domain controllers. There are multiple ways which can be used to acquire them:

  • Phishing and Social Engineering Tactics
  • Trojan Horse Infections
  • Delivery Via Other Malware
  • Vulnerability Exploits
  • Direct Network Attacks

DoppelPaymer Files Virus March 2020 Attack Campaign

A new attack campaign carrying the virus has been reported to us. This time the intrusions were made against a company called Visser Protection — a parts manufacturer that supplies orders to SpaceX, Boeing and Lockheed Martin among others. This high-profile intrusion has been made possible due to a weakness which has been found by the hackers. The identity of the hacking group behind this incident is not known — as the company is considered a high-profile target we presume that the hackers are very experienced.

The full feature list of DoppelPaymer has been enabled which means that a lot of damage will be done to the affected computers. However a difference between this version and previous releases is that the criminals will blackmail to publish the gathered information and not just request a fee payment.

DoppelPaymer Ransomware Virus – Update November 2019

In November 2019, DoppelPaymer ransomware continues to plague users around the World and their computers. The newest iteration of the DoppelPaymer files virus features a brand new ransomware note, which is showcased right down here:


The ransom note states the following:


Ohio Gratings Inc. Your network has been penetrated.

This link and your decryption key will expire in 14 days after your systems were infected.
Sharing this link or email will lead to the irreversible removal of the decryption keys.
NO TIME remains for special price.

All files on each host in the network have been encrypted with a strong algorythm.
Backups were either encrypted or deleted or backup disks were formatted.
No any working decryption software is available from other sources.
Do not rename the encrypted or informational text files. Do not move the encrypted or informational text files.
This may lead to the impossibility of recovery of the certain files.

Also, we have gathered all your private sensitive data.
So if you decide not to pay, we would share it.
It may harm your business reputation.

e Your reference ID: 135

The above proof reveals that ransomware viruses such as DoppelPaymer keep evolving and are being further developed by their authors in order to seek more money from a wider victim base.

DoppelPaymer Files Virus – Detailed Description

The DoppelPaymer files virus is a dangerous new ransomware which is based on an earlier threat known as BitPaymer. According to the available information the responsible hackers are a cybercrime group known as TA505 which are widely known for causing large-scale attacks against finance organizations and banks. The BitPaymer ransomware of which the DoppelPaymer files virus is descendant from was last spotted in a campaign against high-profile targets. The security analysis done of the last major attack shows that a majority of the cases are done by brute force and vulnerability testing which may be automated using suitable frameworks.

At this moment the new variant may use the same strategy or one of the other mechanisms:

  • Phishing Emails — The hackers can send out phishing emails that appear as being sent by a well-known company or service. This is done by imitating the legitimate content and the infections will happen as soon as the recipients interact with them.
  • Hacker-Made Sites — The criminals can create phishing sites that will imitate popular Internet portals. They are hosted on addresses that sound similar to legitimate addresses and may also include security certificates.
  • File Carriers — The criminals can cause virus infections by embedding the required code into file carriers. As soon as they are opened by the victims the infection will be triggered. An example can be an macro-infected document that can take the form of every popular format: spreadsheets, presentations, databases and text files. Whenever one of these files is opened a prompt will be spawned asking the victims to enable the built-in content. If this is done the the DoppelPaymer files virus will be started. The other popular type is the creation of setup packages of popular applications which are commonly installed by end users. These files can also be uploaded to file-sharing networks like BitTorrent where both legitimate and pirate content is found.
  • Browser Plugins — This method is alternatively known as the creation of browser hijackers. They are plugins made compatible with the most popular web browsers and are usually found on their relevant repositories posted with an elaborate description. They are usually uploaded with fake user reviews and developer credentials in order to make them appear.

As soon as the threat is installed on a given system the main engine will call a data harvesting module which can extract information that can be grouped into main categories:

  • Private User Information — It can expose the identity information about the victims including their name, address, phone number and even stored account credentials.
  • Machine Information — A detailed profile of the infected machines can be created automatically by the engine. The DoppelPaymer Files Virus is able to list all installed hardware parts and other sensitive information which can be used further in order to create an unique ID associated wth each machine.

Depending on the exact behavior pattern other system changes can also take place. This can include a boot options modification action. This will automatically start the virus threat as soon as the computer is powered on. This step may also disable the access to the recovery boot options making it very difficult to follow manual user removal guides.

If any Windows Registry changes are made then the virus engine will be able to edit the existing values or create new ones specific for it. This can lead to serious performance issues, data loss and unexpected errors popping up.

The DoppelPaymer Files Virus will launch a file encryption process which will use a strong cipher in order to process target user data. Usually this is done by searching for specific files including the following: databases, multimedia files, documents, archives, backups and etc. In the end the files will be made inaccessible and the victims will be extorted. A ransomware note will be crafted in order to blackmail and extort the users into paying the hackers a decryption fee.

As this particular version is an upgraded iteration of a previous iteration it features a heavily-optimized engine which exhibits better performance. Some of the upgraded versions can also be pushed to infect the other hosts available on the internal network. Whatever the case existing infections need to be removed as soon as possible. Follow our in-depth removal guide in order to attempt system recovery and malware removal.

DoppelPaymer Files Virus – What Does It Do?

The DoppelPaymer Files Virus is a crypto virus programmed to encrypt user data. As soon as all modules have finished running in their prescribed order the lockscreen will launch an application frame which will prevent the users from interacting with their computers.
