Ransomware

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

OnePercent Ransomware

We know that the OnePercent ransomware has been active in the cyber world since the late 2020s. Based on Ransomware as a Service (RaaS) operations, the group behind the OnePercent ransomware has been targeting a number of companies around the world and largely in the United States.

Like many other ransomware, OnePercent typically encrypts a company’s data, threatening to release or auction off the collected information if payment is not forthcoming.

The procedure and some of the tools used by OnePercent are well known to the Federal Bureau of Investigation (FBI), which has taken an interest in the group since the beginning of its attacks.

The OnePercent ransomware relies on the IceID Trojan to get into systems through phishing campaigns and malicious emails. After that invasion, they seek to gain access to the infected system through Cobalt Strike.

According to the FBI, the hackers can remain on the victim’s systems for approximately one month. During those weeks, the OnePercent ransomware spreads through the environment and extracts important data.

To do this, the group must be prepared with tools to act inside the system and go undetected all this time. The OnePercent ransomware can rely on tools such as MimiKatz, SharpKatz and BetterSafetyKatz, the SharpSploit post-exploit library and the Rclone command-line software.

The group is also notorious for taking an aggressive approach with their victims to obtain ransom payments. They call victims using fake phone numbers and send them multiple emails if they have not responded to their ransom demand within a week.

In addition to the procedures used and the various tools involved in the encryption process, for victims who refuse to pay quickly, the group responsible for OnePercent threatens to make the data public. After this warning, if the victim still refuses to pay, the data is transferred to the REvil Sodinokibi group to be auctioned.

The association between these two groups is worrying and very dangerous, as REvil Sodinokibi is actually the most feared ransomware of the last decade.

Certainly, in cases of ransomware attacks, it is essential for a company to be well guarded.

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.
