New Rust-based SysJoker backdoor linked to Hamas hackers

A new variant of the multi-platform malware SysJoker, now written in the Rust programming language, has been linked to Operation Electric Powder, a series of cyber-attacks against Israel dating back to 2016-2017. The new variant uses complex encryption and random sleep intervals to evade detection, and retrieves commands from a OneDrive URL, but lacks some command execution capabilities of earlier versions.
