Remove Coom ransomware (Removal Instructions) - Quick Decryption Solution

removal by Julie Splinters - - | Type: Ransomware

Coom ransomware is the threat that sets the ransom note as lock screens and desktop when the ransom note text file is red

Coom ransomwareCoom ransomware is the cryptovirus that gets released on the system to encrypt common files and make them useless. Developers designed the threat to then release a ransom note READ_IT.txt that directly states what the victim should do next – pay at least 0.015BTC., the ransom can differ from victim to victim, depending on the target and the value of stored and affected files. The particular file is not displaying much information, only stating that the person needs to pay to get those files unlocked and how to obtain Bitcoins for the payment. There is no contact information that could help to communicate with virus developers, so victims have not many options. 

However, paying Coom ransomware virus creators shouldn't be considered a solution no matter what because cybercriminals are not worthy of your trust. By paying the ransom, you risk getting your money collected without receiving a decryption tool of any sort. This is the threat that encrypts files in multiple formats and uses the AES encryption algorithm for that. Also, this is the version of old Eda2 ransomware, so there is no reason to think that coding has some flaws. Cybercriminals may have perfected the coding and made sure to ensure that this threat is not easily detected[1] and removed.

Name Coom ransomware
Family EDA2 ransomware
File marker .coom file appendix appears on every file that got encoded using the AES encryption algorithm, so the victim can differentiate locked files from un-affected data
Symptoms Files get encrypted and useless, the desktop gets changed to a ransom-demanding message wallpaper, and the text file with the same demand appears on the desktop and in various folders with encrypted files. 
Ransom amount 0.015 BTC
Possible payload files EmailExtractor, Super Email Validator,  contract.scr
Ransom note READ_IT.txt is the file that delivers a ransom-demanding message from the virus developers. This file contains information about payment, the amount, and sites where to purchase the Bitcoin. The similar message also gets set as the desktop wallpaper or as a lock screen
Distribution Spam email attachments with infected files and malicious macro viruses embedded on the MS documents directly get send by hiding the content using names of legitimate companies, online shopping, or shipping platforms. These emails pose as notifications with financial data, so people open the attachments without thinking twice and infects the system without even noticing
Elimination Coom ransomware removal can and should be performed using anti-malware tools that can possibly detect this threat and associated files, so the infection is fully terminated
Repair System files that get affected by this threat should also get repaired, and other virus damaged fixed, so rely on system optimization or cleaner tools like Reimage Reimage Cleaner Intego for this

Coom ransomware is an English-speaking users-targeting virus, but it can spread around the world. Especially, when the ransom note is short and specific. Each text file gets personalized with a particular name of the machine that the user has set and victims' ID that is generated by the virus when the encryption is performed on those files all over the computer.[2]

This is the threat that mainly affects Windows devices but can be adapted to macOS later on, so you shouldn't think that your device is immune to cush crypto viruses when you use Apple devices primarily. Even though Coom ransomware focuses on encryption and affecting images, documents, video, audio files, and databases or archives, it still can damage system folders and functions without much effort.

When the encryption process is done, and all the chosen files get locked, Coom ransomware delivers READ_IT.txt with the following text:

To unlock your files send 0.015 BTC (about $150 USD) to the following
bitcoin wallet address:
Once you have sent the bitcoin, make note of your USERID above and the
transaction id of your bitcoin payment and go to
and you will be able to get your decryption key and the decryption tool.
If you are wondering how to purchase bitcoin easily, using
with store bought gift cards is quick and easy, but there are many other ways
to buy bitcoin as well.

This message is followed by changes of the desktop wallpaper and additional lock screens to make people more scared into paying the ransom. However, this is the first, but not the only step in the Coom ransomware attack. Malware can easily access system folders and inject its own files there. Such parts of the machine, like Windows registry entries and startup preferences, get altered to make the virus running after each reboot and continuously.  Coom ransomware virusCoom ransomware - cryptovirus that asks for Bitcoin payments for alleged decryption tools that may not even exist or help with encoded data. If so, you can lose data and money permanently. Experts[3] also note that you need to remove Coom ransomware as soon as possible because it makes the elimination and data recovery especially difficult since it manages to disable functions, install files and delete things needed for the recovery or other options.

Overlooking proper system protection and red flags lead to infections

You cannot notice the infiltration of this cyber threat because it manages to drop the payload file on the system directly without causing any symptoms or particular indications. It happens either when you install software from pirated or malicious sites, fall for scammy updating campaigns or don't pay needed attention to spam emails.

Antivirus programs can help avoid the installation of malicious applications or potentially unwanted programs if you keep them up-to-date and run more often. Pirating software is dangerous because you cannot see all the included files in the package and allow them to infect the machine without knowing.

However, the more common method of spreading ransomware is spam email campaigns that include file attachments filled with malicious macros and other scripts leading to infections like this. You should delete emails when you receive them out of nowhere, especially when the notification contains suggestions about financial details. Such MS documents only need one push of the button to enable the malware drop.

Clean the issues regarding the Coom ransomware infection and restore files yourself

Coom ransomware virus spreads the infection via payload droppers and malicious files triggering scripts and activities on the machine and in the background. You need to find all malicious files since those are the ones that control all the processes, encryption and triggers the damage.

This why automatic methods are more recommended and suggested by researchers, malware experts. Rely on SpyHunter 5Combo Cleaner, Malwarebytes, or anti-malware programs of your choice and run the full system check. 

The professional system security program should indicate all the parts of this or additional viruses and suggest to go forward with Coom ransomware removal.

Coom ransomware decryption tool is not availiable

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

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

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.
