The Mallox Ransomware Gang's Attack on First International Food

The Mallox ransomware gang has attacked First International Food. First International Food is an ingredients supplier headquartered in Jubail, Saudi Arabia. The Mallox ransomware gang posted First International Food to its data leak site on January 25th but provided no further information.

Background of Mallox Ransomware

Industry analysts first detected Mallox in June 2021. The group was initially dubbed "TargetCompany" because it appended encrypted files with the target company's name. In an interview conducted in January 2023, the threat actors responsible for Mallox clarified that each major update of the ransomware involved changing the encryption algorithm and decryptor characteristics. These updates were accompanied by modifications to file name extensions, leading to the evolution of the group's names.

Evolution of Mallox Ransomware

Earlier variants of Mallox provided a contact site with the extension ".onion" for negotiations and delivered ransom notes titled "How to decrypt files.txt." However, the ransomware stopped using the targeted company's name as file name extensions in later variants. During mid- to late 2022, the group was referred to as Fargo due to the extension added to its encrypted files at that time. Additional extensions employed by the ransomware group included ".mallox" and ".xollam." These later variants were observed utilizing a combination of Chacha20, Curve 25519, and AES-128 algorithms for file encryption.

Current Status of Mallox Ransomware

Eventually, the ransomware group established a data leak site called Mallox, and subsequent variants dropped ransom notes labeled "HOW TO RECOVER!!.txt."
