Multi-signature pockets supplier Protected mentioned Thursday that final month’s $1.4 billion Ethereum heist from Dubai-based centralized trade Bybit stemmed from a compromised developer laptop computer.

“We current these findings within the spirit of transparency and to spotlight key classes realized, together with calls to motion for the broader group to study from this incident and strengthen defenses,” it posted on X (previously Twitter). “We want to stress that regardless of a whole bunch of hours of research already carried out, there’s extra work to be carried out.”
The investigation’s key findings highlighted a high-level Protected developer’s workstation being compromised on February 4 when it interacted with a malicious docker mission, or light-weight software.
