A recent ransomware attack on Kronos (reported on here by the BBC) highlights the risks of using online services for business critical functions.
Kronos provide cloud-based services for workforce management and human capital management, which includes payroll services.
Due to the attack, a number of large businesses, including Sainsbury's (a large UK supermarket chain), were unable to process their payroll.
Large corporations like to outsource, including to online service providers like Kronos and Kaseya (read about the Kayeya incident here), because there are cost advantages. The downside, however, is the increased risk of loss of service. A large online or cloud-based service provider is a larger and more interesting target for hackers; why spend time and effort attacking one company, when you can with the same effort attack a service provider and impact many companies? This is why there are so many of these kinds of attack at the moment; almost all attacks target either service providers, providers of software used by many organisations or large multi-site organisations like healthcare provides and government agencies.
There are, of course, contingency measures that one can take to protect against an attack on one's service providers, although they all have a cost. For example have a fallback service provider, to whom you send the same data, whether payroll, print or backup service data. When one's primary provider is hacked, you will be ready to go with an alternative.
