Examples of data theft continue to stream through; no one brand seems immune from having to announce major losses of customer data records. Uber paid US$148 million to settle a legal action over a cyberattack in 2016 that exposed data from 57 million customers and drivers. Forbes reported that Yahoo agreed to pay a US$50 million settlement to roughly 200 million people affected by the email service’s 2013 data breach.
It is still the case that data theft is the leading source of loss for both insurers and reinsurers that cover cyber. The cyber insurance market is still in an early growth stage as the overall economic impact on the global economy from cyberattacks in 2017 was estimated at US$600 billion. Insured loss for standalone cyber policies was a fraction of this, at around US$1 billion to US$1.5 billion. But with cyber risk continually evolving, insurers may have to contend with a new, growing source of loss as cyber attackers are turning to ransomware, as it offers a potentially easier and more lucrative attack method.
Ransomware sees malware infiltrated into the networks of a company and disables servers or locks up data until a ransom is paid. This contagious malware, of which WannaCry and NotPetya are probably the most renowned examples, can even plague companies with high standards of security, and has the ability to scale and to cause systemic loss to thousands of companies. Attackers have also stolen data from a company, and then attempt to extort a ransom from the victim company in return for the data.
Overall, the number of ransomware attacks are increasing each year, and for cyber attackers there is the easy availability of ransomware to buy on the dark web. As outlined in our recent RMS Cyber Risk Outlook Report, estimates of ransomware extorted in 2017 exceed five billion dollars, a 15-fold increase over the previous two years.
