What is an CERBER3 file?

The .CERBER3 file extension is associated with files encrypted by the Cerber ransomware, a type of malicious software. Cerber ransomware, including its third version, is known for encrypting files on infected systems and demanding a ransom payment in cryptocurrency for decryption.

More Information.

Cerber ransomware emerged as part of the ransomware-as-a-service (RaaS) trend, where cybercriminals offer ransomware for rent to other attackers. Its primary purpose is to extort money from victims by encrypting their files and demanding a ransom for the decryption key.

Origin Of This File.

Cerber ransomware was first identified around 2016 and has since evolved through various versions, with Cerber3 being one of its iterations. It primarily spreads through phishing emails, malicious attachments, and exploit kits.

File Structure Technical Specification.

File Encryption: Cerber3 uses strong encryption algorithms (often AES and RSA) to encrypt files. The encrypted files usually have a .CERBER3 extension appended to their original file names.
Ransom Note: Encrypted files are accompanied by a ransom note, often named HELP_DECRYPT.txt or similar, explaining how to pay the ransom and obtain the decryption key.
Malware Payload: The ransomware payload may include various techniques to evade detection, such as obfuscation and anti-analysis measures.
