After suffering a cyberattack back in August, Canon has finally publicly confirmed that the attack was caused by ransomware (opens in new tab) and the cybercriminals responsible stole data from its company servers.
The camera manufacturer's IT department issued a notice to staff on August 5 explaining that the company was suffering “widespread system issues affecting multiple applications, Teams (opens in new tab), email and other systems”, but did not offer further explanation.
Canon then conducted an investigation into the incident and found evidence of unauthorized activity on its network between July 20 and August 6.
