A ransomware attack against a vendor of Oaks-based SEI Investments resulted in a data breach of investors in about 100 of the fund administrator’s clients, write Dylan Tokar, James Rundle, and Juliet Chung for The Wall Street Journal.

The attack found a way into the corporate systems of M.J. Brunner, a service provider that developed and supports the investment dashboard and online enrollment portal used by SEI. Hackers took files containing names and emails, as well as in some cases names, physical addresses, and phone numbers, associated with the dashboard.

The attack was detected in May by Brunner, but it was weeks before SEI knew information belonging to its clients has been breached. Among the funds whose investors were affected were Graham Capital Management and Pacific Investment Management Co.

An SEI spokeswoman noted that the company’s network was not compromised in the attack and that it was not predicated as a vulnerability within its own network.

“We take our clients’ security very seriously, and we are working with Brunner, the FBI, and our impacted clients to understand the extent to which SEI’s or our clients’ data has been exposed,” she said.
