Cyber threats pose a nearly immeasurable risk to an industry based on stored private information. Dark Overlord is the name of an individual or group behind what may be a massive cyberattack on insurance companies. Dark Overlord claims to have stolen files connected with the insurance filings made as a result of the terror attacks of September 11, 2001. If this is the case, Dark Overlord may have achieved the largest ever hack into the insurance industry.
