Ransomware

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

Medusalocker Ransomware

The MedusaLocker ransomware targets its attacks on small and medium-sized businesses. The group was first spotted in September 2019, being noticed by MalwareHunterTeam. The ransomware invades the system from macros, malicious ads, and torrent sites. After execution, Medusa begins to encrypt files by adding extensions making it impossible to access the information. The group uses numerous extensions such as:

.1btc

.marlock02

.bec
.mylock
.jpz.nz
.marlock11

.NET1

It is advisable that in cases of invasion, the machine’s internet is disabled, avoiding the contamination of other systems connected to the same network. The group uses a strategy to attract trust by offering to decrypt a file of the victim’s choice up to 10Mb. MedusaLocker uses AES 256 + RSA-2048 encryption, an algorithm that prevents any free ransomware tool from being successful and can cause permanent data loss if used. To make the negotiation a link is added with the ransom note, allowing the victim to contact the group and make the payment in Bitcoin. However, there is no guarantee of obtaining the decryption key. Therefore, the best way is to turn to companies that specialize in the problem, and Digital Recovery has the right profile to recover files encrypted by ransomware.

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.

How to identify a ransomware attack?

Ransomware is designed to go unnoticed, so it can disable all system defences without being noticed and start the process of encrypting files. Even if ransomware goes unnoticed by the system, it can be noticed by the user, as it uses system resources to perform the encryption, which can slow down the system. Ransomware also changes file extensions. So look out for these signs: slowing down the system and adding extensions to files. To find out more, talk to our experts.

Is it possible to stop the encryption process?

Yes, this is possible. You can restart the computer in safe mode, which will limit the action of the ransomware since the system resources will be locked. You can also disconnect the computer from the Internet, which can interrupt the hackers’ connection to your system, it should be noted that there are ransomwares that work even without being connected to the Internet. You can also run diagnostics to identify threats with your antivirus software, the vast majority of antivirus software 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 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.

Is there a day and time when ransomware attacks are most prevalent?

Yes, the attacks mainly take place on holidays and weekends, in the early hours of the morning. These days are chosen because there are not many active users on the system, making it impossible to discover the attack before the encryption is complete. To find out more, talk to our experts.

What is the encryption used by the hackers?

The vast majority of ransomware uses RSA [Rivest-Shamir-Adleman] -2048 and AES [Advanced Encryption Standard] encryption. To find out more, talk to our experts.

What to do after a ransomware attack?

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 specialised cybercrime departments that will investigate the attack. Next, check if your backups have been affected, if so, only a specialist data recovery company can recover your files, this is the next step. Contact Digital Recovery who will assist you in the full recovery of your files. To find out more, talk to our experts.

How does the digital recovery process work?

After contacting us and sending the affected media, we will diagnose the device to verify the extent of the damage caused by the ransomware, which will allow us to predict the duration of the process and provide the client with a budget. Once the budget is approved by the client, we begin the recovery process, for which we have proprietary software that can, with the help of our specialists, reconstruct the data. If the client opts for remote recovery, instead of sending us the media, they will send the encrypted files to a virtual environment, totally secure, so that we can access them. At the end of the process, we will perform a double check so that the customer can verify the integrity of the recovered files. Payment is only made once the files have been delivered and validated by the client. To find out more, talk to our experts.
