Back in 2023 of September Johnson Controls experienced a huge ransomed attack Over 27 TB of data was stolen, and the ransom was set at $51 million. The breach is believed to have originated within Johnson Controls offices in Asia, where attackers exploited weaknesses in regional systems. The ransomware deployed in the attack was developed using leaked source code from the Babuk and Ragnar Locker ransomware families. Babuk and Ragnar are both hacker groups this led to Johnson Controls loss of 27 million dollars it took 23 million to solve the problem and they had a 4 million loss in revenue. The Ransome attack warned other companies on how serious cyber-attacks can be and should be taken more seriously especially companies that manufacturing and infrastructure, which should strengthen their defenses against cyber threats. Luckily Johnson Controls used backups and other tools available to recover systems and applications. Customer platforms, like their Simplex Customer Portal, faced some delays, however most operations resumed quickly.
