Crbr Ransomware is the brand-new variant of the nasty Cerber Ransomware that was recently prevalent as RaaS (Ransomware-As-a -Service). This variant is said to have received slight modifications by the developers. It is the most widely spread & active member of the infamous Cerber Ransomware family.
Exploit Kits & Spam e-mail Campaigns are the prime techniques used by Crbr Encryptor to proliferate its infection. Apart from these, crbr Ransomware uses several other techniques to propagate such as malware-laden websites & infected e-mail attachments.
After encrypting the files, Crbr Ransomware renames the files by appending four random characters to the filenames. The encrypted files are instantly made inaccessible to the users. It then displays a ransom-demanding note (a program window) named crbr Encryptor Instructions. The note asks the victims to pay the ransom in exchange of the decryption tool & private key.
Read on to know if victims are able to restore the data by paying ransom. Also learn what the possible ways of preventing Crbr Encryptor attack are.

Crbr Ransomware is a file-encrypting virus that belongs to the devious Cerber Ransomware family. This Ransomware is majorly infecting Windows-based systems around the world. Exploit kits, Spam e-mail campaigns, infected attachments & suspicious websites are some of the chief methods used by this Ransomware to spread.
Once the system is infected, it locates the targeted file extensions & uses RAS-2048 Encryption Algorithm to encrypt the files. After encryption, it appends a random four letter extension to the filenames, thus making them inaccessible to the users.
Randomly used characters include 0 to 9 and A to Z characters.
Let us understand the encryption & renaming with the help of an example:
A file named myimage.jpg might be renamed as myimage.jpg.bs80 after encryption.
Crbr Ransomware is capable of targeting a myriad of file extensions & encrypting them.
These include:
1). Document files (.docx, .doc, .odt, .rtf, .text, .pdf, .htm, .ppt)
2). Audio Files (.mp3, .aif, .iff, .m3u, .m4u, .mid, .mpa, .wma, .ra, .avi, .mov, .mp4)
3). Video Files (.3gp, .mpeg, .3g2, .asf, .asx, .flv, .mpg, .wmv, .vob)
4). Images (.jpg, .jpeg, .raw, .tif, .gif, .png)
5). Backup Files (.bck, .bckp, .tmp, .gho)
Details of the Ransom Note of Crbr Ransomware
After successful encryption of the targeted files, a scary notification in the form of a program window appears on the screen.
This program window is the ransom-demanding note that explains the present situation of the system & files to the users. It notifies the user about the encryption of the files & asks them to pay the ransom in exchange of the decryption key.
The detailed instructions to retrieve the private key & decryption tool are in a file named “*_R_E_A_D___T_H_I_S___*.txt”, which is dropped in every folder containing encrypted files.
As per this file, the victims are required to pay $100 (approximately equal to 0.073 in Bitcoins) for the decryption tool & private unique key.
The ransom amount remains unchanged if the victims manage to contact the hackers within 5 days of encryption. Failing to contact the hackers in 5 days leads to increase in the ransom amount to 1 Bitcoin. The hackers claim to send the unique key & decryption tool after receiving the payment.
Despite these claims, the victims are advised not to contact the hackers as paying the ransom don’t guarantee the decryption of files.
The victims should act smart & use guidelines to remove crbr Encryptor virus from the system.
The cyber-criminals use various strategies for malware distribution which include –
To restart the system to Safe Mode with Networking, if already switched ON then follow the below steps:
5 Once the system restarts, click on the username and enter the password (if any) to log in.
Once the system starts, ensure to use an account with administrative privilege to access Safe Mode with Command Prompt.
After the user enters admin credentials, Command prompt window is displayed wherein you are entitled to enter the below commands:
