In a breach notification letter filed with New Hampshire's Office of the Attorney General, Bose said that in early March 2021, the company "experienced a sophisticated cyber-incident that resulted in the deployment of malware/ransomware across" its "environment."
At the time, Bose initiated incident response protocols, activated its technical team to contain the incident and hardened its defense against unauthorized activity. In conjunction with expert third-party forensics providers, Bose initiated a comprehensive process to investigate the cyberattack, and worked with its cyber experts to bring its systems back online. As the system was restored, the company worked with forensic experts to determine the data that was accessed and exfiltrated.
