"description": "Ransomware",
"description": "BlackByte is recently discovered Ransomware with a .NET DLL core payload wrapped in JavaScript. It employs heavy obfuscation both in its JavaScript wrapper and .NET DLL core.\n\nOnce the JavaScript wrapper is executed, the malware will de-obfuscate the core payload and execute it in memory. The core .DLL is loaded and BlackByte will check the installed operating system language and terminate if an eastern European language is found.\n\nIt will proceed to check for the presence of several anti-virus and sandbox-related .DLLs, attempt to bypass AMSI, delete system shadow-copies in order to hinder system recovery, and modify several other system services (including Windows Firewall) in order to “prep” the system for encryption. Once the system is “ready” for encryption, it will download a symmetric key-file which will be used to encrypt files on the system. If this file is not found, the malware will terminate.\n\nUnlike most Ransomware today, BlackByte uses a single symmetric encryption key, and does not generate a unique encryption key for each victim system, meaning the same key can be used to decrypt all files encrypted by the malware.\n\nThis makes for substantially easier key-management for the actors behind BlackByte at the cost of a weaker encryption scheme and easier victim system recovery (as there is only a single online point with a single key to maintain).\n\nAs with most Ransomware today, BlackByte has worming capabilities and can infect additional endpoints on the same network.",

"description": "STRRAT is a Java-based RAT with a JavaScript wrapper/dropper that was discovered in 2020. Its core payload (a .JAR file) is contained under several layers of obfuscation and encoding inside the JavaScript wrapper/dropper.\n\nSTRRAT is propagated by malicious email attachments. Its capabilities include standard RAT functionalities (remote access, remote command execution), browser and email-client credential harvesting, and a unique ransomware-like functionality if instructed, it will add a “.crimson” extension to files on the device, rendering them inoperable (though they can be easily recovered because their content is not modified).\n\nUnlike many Java-based malware, STRRAT does not require Java to be installed on the infected system in order to operate. When the JavaScript wrapper/dropper is executed, if a suitable Java runtime installation is not found, one will be downloaded and installed in order to assure the contained Java payload can execute.",
