What is Mammon Ransomware

Developed by the Makop Ransomware family, Mammon is a dangerous virus that runs data encryption for monetary goals. This is because it encrypts personal data with military-grade algorithms and demands money ransom to be paid by victims. To show that your data has been restricted, extortionists append a string of symbols to each file name (including random characters, cybercriminals’ e-mail address, and .mammon extension). To illustrate, the original file like 1.pdf will change its look to something like this 1.pdf.[9B83AE23].[mammon0503@tutanota.com].mammon. As a result of this change, users will no longer be able to access the file. In order to get instructions on recovering data, cybercriminals create a text note called readme-warning.txt to each folder with encrypted data.

::: Greetings :::
Little FAQ:
Q: Whats Happen?
A: Your files have been encrypted and now have the "mammon" extension. The file structure was not damaged, we did everything possible so that this could not happen.
Q: How to recover files?
A: If you wish to decrypt your files you will need to pay in bitcoins.
Q: What about guarantees?
A: Its just a business. We absolutely do not care about you and your deals, except getting benefits. If we do not do our work and liabilities - nobody will cooperate with us. Its not in our interests.
To check the ability of returning files, you can send to us any 2 files with SIMPLE extensions(jpg,xls,doc, etc... not databases!) and low sizes(max 1 mb), we will decrypt them and send back to you. That is our guarantee.
Q: How to contact with you?
A: You can write us to our mailbox: mammon0503@tutanota.com or mammon0503@protonmail.com or samsung00700@tutanota.com or pecunia0318@goat.si
Q: How will the decryption process proceed after payment?
A: After payment we will send to you our scanner-decoder program and detailed instructions for use. With this program you will be able to decrypt all your encrypted files.
Q: If I don’t want to pay bad people like you?
A: If you will not cooperate with our service - for us, its does not matter. But you will lose your time and data, cause only we have the private key. In practice - time is much more valuable than money.
DON'T try to change encrypted files by yourself!
If you will try to use any third party software for restoring your data or antivirus solutions - please make a backup for all encrypted files!
Any changes in encrypted files may entail damage of the private key and, as result, the loss all data.

This note contains detailed information on contacting the swindlers and recovering data eventually. Besides greeting victims with disappointing news, they are telling that data can be decrypted. To do this, users have to write a message to one of the e-mails listed (e.g. mammon0503@tutanota.com; mammon0503@protonmail.com; samsung00700@tutanota.com; pecunia0318@goat.si). Once they confirm receiving your message, you will be given instructions to pay for the decryption software (in bitcoins) – a private scanner-coder program capable of decrypting the blocked data. To prove that they are not going to fool you, developers offer to send them 2 files without valuable data for free decryption. Such an offer will by far prove their ability to decrypt the data. However, there have been many cases when cybercriminals did not send any tools even after paying the ransom. This is why it is a risk whether to pay them or not. Unfortunately, there are no third-party tools that could grant full data decryption without the help of cybercriminals. The only way to return files without paying money is to recover them from backup copies. However, before doing so and connecting external devices, it is important to uninstall Mammon Ransomware from your computer first. Only then you can use the backup option or try to follow our instructions below. We do not guarantee that you will return all of the files, but still worth trying if you are unable to pay the ransom.

How Mammon Ransomware infected your computer

Threats like ransomware are predominantly spread via e-mail spam, trojans, unprotected RDP configuration, backdoors, keyloggers, fake software installers, and more to be cautious of. E-mail spam is a popular method used to deliver malicious letters. These messages are part of ostensibly legitimate campaigns that send newsletters. Inside of them, cybercriminals include highlighted text explaining why users should open the attached files (MS Office documents, PDFs, executables, JavaScript files). If opened or clicked on the attached links, there is a high chance to be infected with a malicious program. It can be ransomware infections or trojans that deliver the installation of them. Note that averting such infections after initiating the malicious file will be impossible. The process is imminent and non-dodgeable unless you have anti-malware software installed. This is why it is important to stay miles away from content received from suspicious sources. In our guide below, you will find extended information on system protection against such threats in the future.

2. Back up your files

idrive backup

As an additional way to save your files, we recommend online backup. Local storages, such as hard drives, SSDs, flash drives, or remote network storages can be instantly infected by the virus once plugged in or connected to. Mammon Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox
