Linux Version of DinodasRAT

A Linux model of a multi-platform backdoor referred to as DinodasRAT has been detected within the wild concentrating on China, Taiwan, Turkey, and Uzbekistan, new findings from Kaspersky reveal.

DinodasRAT, also called XDealer, is a C++-based malware that provides the flexibility to reap a variety of delicate knowledge from compromised hosts.

In October 2023, Slovak cybersecurity agency ESET revealed {that a} governmental entity in Guyana has been focused as a part of a cyber espionage marketing campaign dubbed Operation Jacana to deploy the Home windows model of the implant.

It additionally takes steps to evade detection by debugging and monitoring instruments, and like its Home windows counterpart, makes use of the Tiny Encryption Algorithm (TEA) to encrypt C2 communications.

“DinodasRAT’s main use case is to achieve and preserve entry through Linux servers moderately than reconnaissance,” Kaspersky stated. “The backdoor is absolutely purposeful, granting the operator full management over the contaminated machine, enabling knowledge exfiltration and espionage.”
