Background for this topic.
A remote access trojan (RAT) is malware that gives an unauthorized operator remote control over an infected device. Depending on its design, it may execute commands, browse or copy files, log keystrokes, capture screens, or use a microphone or camera. RATs commonly communicate with attacker-controlled command-and-control infrastructure; capabilities and persistence vary, so reporting should identify the specific family or tool rather than assume every RAT has the same functions.
The main concerns are covert access, exposure of sensitive data, and use of the host to deploy additional malware or alter systems. Defenders should monitor endpoint processes and network behavior, restrict unnecessary outbound connections, keep software patched, and use endpoint controls that can detect unusual remote-control activity. If a RAT is suspected, isolate the device, preserve relevant logs and malware samples, investigate related accounts and hosts, and rotate credentials after containment; blocking one server alone may not remove persistence.
The two allegedly sold the Trojan on Hack Forums, allowing other threat actors to gain unauthorized control, disable programs, browse files, record keystrokes, and steal credentials.
The threat actor tracked as TA558 has been observed leveraging steganography as an obfuscation technique to deliver a wide range of malware such as Agent Tesla, FormBook, Remcos RAT, LokiBot, GuLoader, Snake Keylogger, and XWorm, among others
Two individuals have been arrested in Australia and the U.S. in connection with an alleged scheme to develop and distribute a remote access trojan called Hive RAT (previously Firebird)
