What we know about the Brown Brothers Harriman data breach

According to an official notice filed by the company, in December 2021, BBBH was notified by one of its third-party vendors, RR Donnelley & Sons Company (“RRD”), that the company had been the target of a cyberattack. Thanks to independent sources, it has been confirmed to be a ransomware attack.

Initially, RRD informed BBH that the breach only affected RRD’s systems and that no BBH data was involved. However, in March 2022, RRD contacted BBH to tell the company that during the cyberattack, the unauthorized party extracted the BBH files from RRD’s system.

After discovering that sensitive consumer data was accessible to an unauthorized party, Brown Brothers Harriman then reviewed the affected files to determine exactly what information had been compromised. Although the information breached varies depending on the individual, it can include your name, mailing address, social security number, and account number. The Brown Brothers Harriman data breach is thought to have affected up to 2,800 people.

On May 11, 2022, Brown Brothers Harriman sent data breach letters to everyone whose information was compromised as a result of the recent data security incident.

Liability following a data breach

Under US data breach laws, companies may be financially liable to consumers whose information is disclosed as a result of a data breach. However, the mere fact that a breach has occurred is not sufficient to engage the liability of a company; there must be evidence that the company was negligent and that the negligence led to the breach.

Taking the example of the BBH breach, there are two potentially liable parties. First, RR Donnelley & Sons, the target of the breach that led to the information leak, may have been negligent in safeguarding the data entrusted to the company. For example, this could be because the company did not have an effective data security system in place, it mishandled a ransomware attack, or a company employee provided the access to an unauthorized party.

The other party potentially responsible for a breach like this is BBH. Admittedly, BBH appears to be a victim of the breach of the RRD. However, at the same time, BBH has a duty to its customers to ensure that third-party providers to whom it entrusts customer data have data security systems in place to protect that information.

Of course, it’s too early to tell if any of these companies are responsible for the breach. Those who wish to learn more about what steps to take following a data breach to protect themselves should contact an experienced data breach law firm as soon as possible.
