Ransomware

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

Conti Ransomware

In May of this year, the FBI released an alert about the considerable increase in attacks carried out by the Conti Ransomware. They use the RaaS (Ransomware as a Service), which is a way of outsourcing the spread of this ransomware, amplifying the number of attacks exponentially. They are evolving this type of service, instead of paying just a commission to collaborators, they pay a monthly fee, making them affiliates.

The FBI reported an increase of 400 attacks by Conti Ransomware in the last month, targeting companies around the world, prompting the FBI to release the alert.

They act like all other ransomware, they lock files with encryption and demand payment of a ransom amount to release data. In addition to blocking, they threaten to leak the files if the ransom is not paid within the stipulated time.

According to the FBI, the main gaps that this ransomware uses are:

Spear phishing campaigns using personalised emails that contain malicious attachments or malicious links;
Malicious attachments often contain embedded scripts that can be used to download or discard other malware – such as TrickBot and IcedID and/or Cobalt Strike – these malwares support the attack lifecycle with the ultimate goal to deploy the Conti Ransomware;
Weak or stolen Remote Desktop Protocol (RDP) credentials;
Phone calls;
Fake software promoted through search engine optimisation;
Other malware distribution networks (eg ZLoader); and
Common vulnerabilities in external assets.

The risk of an attack from this ransomware is real, so Digital Recovery strives to develop technologies capable of recovering files encrypted by ransomware of any extension.

Recover Files Encrypted by Conti Ransomware

The recovery of encrypted files is possible thanks to the Tracer, which is an exclusive technology from Digital Recovery. By doing thousands of calculations it can locate, repair, reconstruct and, thus, recover data without the need for a decryption key.

We know how delicate this situation is, so the entire process is done in a completely discreet manner and the entire process is in accordance with the GDPR (General Data Protection Regulation) and we can also sign an NDA (Non-Disclosure Agreement) in order to bring guarantees that the case will not be disclosed.

Only a few companies around the world are capable of making this kind of recovery, which is why many say it is impossible, which in fact it was until a few years ago. But, we never accepted this as an absolute truth, it was just another barrier to be overcome, and afterall we were able to develop the solution. Since then, we’ve helped companies save more than US$ 20 million by not paying the ransom requested by cybercriminals.

If you have been attacked by Conti Ransomware, contact our experts and see what we can do for you.

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.
