Recover MySQL Database

MySQL is one of the best known databases in the world for its simplicity and effectiveness. But still, there are cases of data loss in MySQL, and if this happens you need to know how to proceed with data recovery.

Throughout this article I will show you how MySQL came to be the best known data storage program and what are the causes of data loss, and how to do recovery of database attacked by ransomware.

Let’s take a closer look at it and see what it has to be so successful on the market.

What is MySQL?

MySQL was created in 1995 by David Axmark and Michael Widenius, two Swedish programmers.

MySQL AB is the developer of MySQL, the company was bought by a number of companies over time and today the company is owned by Oracle, the American giant.

Today MySQL is the most widely used data storage program (DBMS) in the world. Its ease and speed have caught the attention of large companies. Companies such as Wikipedia, Motorola, Bradesco, Sony and even NASA use this program. This already shows its quality and effectiveness.

MySQL is a relational data storage program, i.e. the data is separated in specified folders for each piece of information, and these folders are related to each other to facilitate the organization of the files.

MySQL uses SQL (Structured Query Language). It partitions the information for easy organization. The program is simple and works on any platform. And, it continues to advance constantly. SQL also has its system open, letting customers change its interface as much as they want.

MySQL’s system analyzes all your information to avoid any duplicate files and detects and resolves any kind of file failure.

MySQL has a high availability, it is always available for you to access your data. Should something happen to your servers, your data and files are safe.

MySQL Data Loss

MySQL is not completely fail-safe, like any other system, no matter how technological, data loss is a real risk. There are a few reasons for data loss in MySQL:

  • Human error – The most recurring is by human error, an accidental deletion or even a formatting.
  • Hacker attack – There are also data loss by ransomware attacks, which is very dangerous.
  • Internal errors – There can also be an error in the MySQL program itself that can corrupt the data as it is being recorded.

Data loss by ransomware attack is the most worrying and dangerous, hacker groups develop their malicious programs for targeted database attacks, targeting to encrypt all the files stored in the system.

These attacks cause losses due to the downtime of the company, the blocking of the files, and generate losses due to the huge amount of money that is demanded in ransom for the release of the decryption key.

Many companies can recover databases that have lost their data due to physical or logical damage, but few can decrypt databases attacked by ransomware, among them RansomHunter.

Decrypt MySQL Database Files

Database decryption is extremely difficult to do because of the large amount of data, and especially when it is relational like MySQL.

RansomHunter has deep knowledge about database and develops exclusive technologies to enable us to decrypt files affected by ransomware.

We act in cases of high complexity, our DBA’s are highly qualified and available to act at any time.

Our solutions can be executed remotely, this speeds up the data recovery process time. During the entire process, the customer will be accompanied by our specialist, who will provide constant feedback on the progress of the process.

Frequently Asked Questions About Ransomware Recovery

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.

Yes, yet the ransomware is designed not to be identified by the firewall, so it can infiltrate the company’s internal system and disable defenses, move laterally, and alter backup routines.

The user can identify the ransomware action, even if the system cannot identify it, the malware uses the system’s own resources for the encryption process, and may be slow to respond to user requests.

The file extensions are changed, a specific extension is added that mentions the attacker group. Stay tuned for these signs.

Yes, it is possible. But there is a risk that some files will be corrupted. Once you identify the ransomware action on the system, disconnect the device from the internet, this will break the group communication with the malware, some ransomware can continue encryption even without internet access.

You can also initiate antivirus countermeasures to isolate the malware and delete it, if the antivirus has not been disabled by the ransomware.

Stopping the encryption is extremely difficult, the ransomware is designed to disable any system or user countermeasures, decreasing the chances of the process being interrupted.

The attacks usually happen when there is a drop in the flow of users in the system, which happens on weekends and holidays, during the early hours of the morning, making these dates suitable for attacks.

There are numerous encryption algorithms, but the most widely used are RSA [Rivest-Shamir-Adleman]-2048 and AES [Advanced Encryption Standard].

First of all, keep calm, criminals count on the victim’s desperation. Follow these tips:

  • Isolate the affected device – The ransomware can move laterally through the system and reach other devices, so it is important to isolate its field of action.
  • Verify backup – If the backup has not been reached by the ransomware, data can be quickly restored without major problems.
  • Avoid contact with criminals – Criminals use psychological tactics to extort as much money as possible in the shortest possible time, the fact that the victim is emotionally involved with the incident makes him an easy target.
  • Don’t negotiate with the criminals – The group gives no guarantee that the decryption key will be released after the ransom is paid, you have to take only the criminals’ word for it. Besides the payment will fund the group for further attacks.
  • Contact government authorities – The government has agencies that specialize in combating cyber attacks, which will investigate the case.
  • Contact a company that specializes in decrypting Ransomware files – RansomHunter is able to decrypt ransomware files without the need for the decryption key, their solutions are an option to paying the ransom.

After the first contact and sending of the data we will diagnose the files to check the extent of the damage caused by ransomware, with this we can project the duration of the process and provide the budget.

After the client approves the budget, we start the decryption process, for this we have exclusive software that can, with the help of our specialists, reconstruct the data.

After the end of the process we will do a double check so that the client 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.
