AM Best warns the PHP flaws could become a systemic cyber event, with losses reaching D&O cover

Rating agency AM Best says the critical PHP vulnerabilities disclosed this month could become a systemic event for cyber insurers, Carrier Management reported.

AM Best also expects claims to emerge over a long period and a large gap between economic and insured losses.
