A sample of the ransomware written in Rust language and the variant has also been seen using intermittent encryption tactics to deliver faster encryption and avoid detection more efficiently. Earlier with Go language as backend, it is found targetting Thailand and Indonesia

Unlike the previous Golang variant, the Agenda ransomware group did not include the victim’s credentials in the Rust variant’s configuration.

This feature of the latter prevents other researchers not only from visiting the ransomware’s chat support site but also accessing the threat actors’ conversations when a sample becomes available externally.
