Database, Ransomware
If your files have been encrypted, we accept the challenge of analyzing your case.

What is MySQL?

MySQL is a database management system (DBMS), utilizing the SQL language (Structured Query Language) using it in the interface. It is a relational database management system (RDBMS).

RDBMS runs on open source code, used in database management, in relational models. It is written by a programming language, but uses SQL as primary, MySQL is written in C and C++.

The project creation began in the year 1980, created by David Axmark, Allan Larsson and Michael Widenius. MySQL AB, the developer of MySQL, was purchased by Sun Microsystems for $1 billion on January 16, 2008. After that, in April 2009, Sun Microsystems was acquired by Oracle, including all its products, including MySQL.

MySQL is extremely useful with its simple interface and its ability to run on many operating systems. MySQL has a free license, also known as a program with open source code, giving the possibility to the user to make changes in the software, however there is a company that manages what can be changed or not, known as GLP (GNU General Public License), determining what is or cannot be changed.

In MySQL, the user can choose 3 table formats, which are: ISAM, HEAP and MyISAM, also the most updated versions accept the tables: InooDB or BDB. Once you create the table, you must choose which model to use, the most common is MyISAM.

The MySQL file contains the .frm extension, automatically generated by the system.

Ransomware Ataque

MySQL Encrypted by Ransomware

Ransomware is malware that aims to break into, encrypt and extract as many files as possible, it acts like a data hijacker. With encryption it blocks all access to the company’s internal files, thus paralyzing its operation and causing significant damage to the company.

Some ransomware groups use double extortion, which is the encryption plus the theft of sensitive files for the company, and if the blocking does not lead the company to pay the ransom demanded by the criminals, the stolen files are disclosed on the dark web. Groups that act this way have exclusive sites for leaking files.

Speaking directly of MySQL, after the ransomware invades it, it blocks the administrators’ access, thus starting the encryption of the files and tables.

The files generated by MySQL have the extension .frm, after encryption, the ransomware itself creates its extension, preventing access to the files and information.

Ransomware has its extensions, and they are different, each ransomware contains its own, and they contain different rules from each other. However, most of them are created with the same standard AES and RSA encryption. This makes it impossible to bring the files back.

The hackers ask for a ransom that needs to be paid in cryptocurrencies to release the decryption key. But, there are no concrete guarantees that the data will be decrypted after payment.

The ransomware leaves a ransom note on the system explaining what happened and leaving the contact for the company to contact for the ransom payment.

It is worth remembering that you need to have a professional setup on your security devices. If you use an Antivirus, make sure it is professional. It is advisable to have an individual Firewall for the server that contains the MySQL database, there is external Firewall like Pfsense, well secured and configurable to enhance the security of your database.

After having a security setup, it is important to perform daily backups of your data. Even though MySQL is very secure, it can be hacked. There are configurations that allow you to perform automatic backups.

Ransomware Recovery FAQ

Every day, ransomware attacks get better and better. After a successful attack attempt, ransomware quickly maps the user’s most important files to begin encryption. Microsoft Office files, databases, PDFs and design are among its main targets.

Ransomware is designed to be unnoticeable, so it can disable all system defenses without being noticed and start the process of encrypting the files. Even though ransomware can go unnoticed by the system, it can still be noticed by the user, because ransomware uses the system’s own resources to do the encryption, this can slow down the system. Ransomware also changes file extensions. So be on the lookout for these signs: System slowdown and extensions being added to files.

Yes, it is possible. You can restart the computer in safe mode which will limit the ransomware’s action as system resources will be locked. You can also disconnect the computer from the Internet which can interrupt the hackers’ connection to your system, it is worth remembering that there is ransomware that works even without being connected to the Internet. You can also start the diagnostics to identify threats with your antivirus, the vast majority of antiviruses have this function.
But there are cases where the encryption was interrupted by the user, some files had already been affected and this caused an error in the encryption and even the hackers could not restore the files, even with the decryption key. In these cases only a data recovery company, such as Digital Recovery, can recover the files.

To find out more, talk to our experts.

Yes, attacks usually happen mainly on holidays and weekends during the early morning hours. These days are chosen because there are not many active users on the system, which prevents the attack from being discovered before the encryption is completed.

To find out more, talk to our experts.

The vast majority of ransomware uses RSA [Rivest-Shamir-Adleman]-2048 and AES [Advanced Encryption Standard] encryption.

First of all, do not pay the ransom. No matter what the hackers say, there is no guarantee that the decryption key will actually be released after the ransom is paid.
The first thing to do is to inform the authorities about the attack, governments have specialized cybercrime departments that will investigate the attack. After that, check if your backups were affected, if they were, only a company specialized in data recovery can recover your files, this is the next step. Contact Digital Recovery who will assist you in the complete recovery of your files.

After first contacting us and sending the affected media we will diagnose the device to check the extent of the damage caused by the ransomware, with this we can project the duration of the process, and provide the budget to the customer. After the budget is approved by the customer, we start the recovery process, for this we have exclusive software that can, with the help of our specialists, reconstruct the data.
If the customer opts for remote recovery, instead of sending us the media, he/she will send the encrypted files to a virtual environment, which is totally safe, so that we can access them.
After the end of the process we will do a double check so that the customer can verify the integrity of the recovered files.
Payment is only made after delivery of the files and validation of the same by the client.
