When cyberattacks strike global giants, it’s front-page news. But what about the smaller breaches -- the ones that don’t make headlines? Increasingly, they’re making waves in courtrooms and regulatory enforcement agencies.
Even if an organization manages significantly less data than an enterprise-level company, recent cases involving small- to mid-sized businesses show that no breach is too minor for major legal risks. Fortunately, there are practical steps that organizations of all sizes can take to strengthen their cybersecurity posture and reduce their legal exposure.
Small incidents can have “mega” consequences
A few years ago, smaller cyber attacks might have gone without legal action. That is no longer the case. Today, even small incidents can result in lawsuits and regulatory inquiries.
One example is MedStar Health. In 2023, a breach affecting 183,000 individuals -- small by industry standards -- led to six class action lawsuits that were consolidated in a single settlement. The breach stemmed from unauthorized access to employee email accounts. In other words, it was not a sophisticated hack. More recently, plaintiffs’ attorney websites have been found to be soliciting class participants in matters publicly disclosing that fewer than 1,000 individuals were affected.
In addition to victims (or plaintiffs’ lawyers) who are more likely to be aware of breaches and to sue, regulatory enforcement agencies are more active, and breach-notification laws are expanding. At
