Remove NBES Ransomware Virus (2019 Guide)

NBES ransomware encrypts files to extort the victim

NBES is a ransomware-type virus that comes from STOP/DJVU group. It is a malicious Windows program designed to encrypt files on victims PC with RSA cryptography. During the attack, the malware deletes system restore points, disables active firewalls, modifies files and adds .nbes file extension after the original one. Finally, the virus drops _readme.txt files to inform the victim about what happened and present the ransom demand. The hackers ask for $490 if paid within 3 days or $980 later.

NBES file virus is designed to compromise computer system silently. Most of the victims download this virus from malicious downloads. Once executed, the virus starts encrypting files folder after folder. The way it modifies files cannot be reversed without a special key, known as a private decryption key. This key is held by cybercriminals who created this virus.

Therefore, the ransomware creates _readme.txt files which explain the victim what happened. The ransomware suggests paying a ransom in Bitcoin cryptocurrency to recover files. The victim can test the decryption software by sending the attackers one encrypted .nbes file to [email protected] or [email protected]. The ransom note warns not to send any files that contain valuable information.

NBES file virus is known to silently install AZORULT Trojan on the system, which is a malicious private data stealing malware. It can grab your login details such as passwords and transmit them to cybercriminals. Therefore, if you have noticed that your files were encrypted by this STOP/DJVU variant, we suggest you take actions without any hesitation.

Remove NBES ransomware virus using the free tutorial provided below. You will need to boot your PC in Safe Mode to eliminate the threats safely.

Threat Summary

Data encryption routine and prospects on data decryption

NBES ransomware uses an extremely secure way to encrypt files. Think of it as the encryption used to secure military-grade secrets. The attackers are the only ones who know the decryption keys. However, the ransomware is designed to operate with or without the Internet connection, which it needs to connect to its Command & Control server. Therefore, the offline encryption is the “flaw” that can help to recover files for some victims.

The ransomware attempts to connect to its C&C server so it could obtain an online (an individual) key for each victim. If it fails to connect to it, it uses a static offline key which is the same for all variants of NBES ransomware. Therefore, after a while, security researchers might succeed to obtain this key and upload it to STOP Decrypter.

To figure out which key was used for your data encryption, go to C:/SystemID/PersonalID.txt and check if any of the keys end in t1. It is an indicator of an offline key, which means some of your files can be restored in the future.

If your keys don’t end in t1, there is no way to recover files without paying the criminals.

However, we do not encourage paying the attackers. By paying them, you simply encourage them to run their business. However, paying might be the last rescue if your organisation’s future depends on data that was destroyed.

STOP ransomware spreads via malicious tools

All variants of STOP/DJVU ransomware, including the latest versions NBES, MKOS, RIGH, MERL and others, are transmitted via malicious file packs available to download online. You should stay away from various file sharing sites, especially those that suggest illegal downloads such as pirated software packs, software cracks, license key generating tools (also known as keygens) or tools like KMSPico. This ransomware variant is known to be distributed in this one unique way.

In the meantime, you also need to be aware of other ransomware distribution tricks, including malicious spam (deceptive emails that supposedly come from authorities or well-known organizations and suggest opening links or attachments). You should also be aware that malware can be transmitted not only in a form of .exe file, but most frequently Word documents or Adobe Acrobat PDF files as well.

Therefore, you need to stay away from all suspicious emails you weren’t expecting. Resist the urge to open a message that you weren’t waiting for, and even if you did, scan the download with a robust antivirus before opening it.

Remove NBES ransomware virus from the system safely

The tutorial provided below explains how to remove NBES ransomware virus from the system safely. You need to eliminate all remains of the virus and Azorult Trojan with a trustworthy antivirus tool of your choice. You can choose free or paid options available today.

NBES ransomware removal will ensure a safe environment to start recovering your files from a backup. Please do not connect your data storage device to the compromised PC before deleting the malware first. This can cause data encryption on your backup, too!
