It’s speculated that the cyberattack is linked to a Chinese cyber-espionage group, Tick (or Bronze Butler), that is well-known for targeting Japan over the past few years. The unauthorized access was tracked to a compromised employee account. Hackers were also able swipe 200 MB of files by accessing Mitsubishi Electric’s internal systems and networks.
