Fidelity Brokerage Services Hit by Three-Day Cyberattack in August 2024, Exposing Sensitive Customer Data
In August 2024, Fidelity Brokerage Services suffered a three-day cyberattack that exposed the personal and financial data of approximately 77,000 customers, including passport details, driver’s license numbers, Social Security numbers, credit card information, and medical records. The breach, which occurred between August 17 and 19, was the result of a vulnerability in Fidelity’s online access controls, allowing unauthorized access to a document repository.
A bad actor exploited a flaw in the system’s "Image ID" parameter, enabling them to manipulate browser URLs to view other customers’ documents. While Fidelity detected and halted the breach within days, the Massachusetts Secretary of the Commonwealth, William Galvin, issued a $1.25 million fine against the firm for failing to enforce adequate cybersecurity measures. The consent order revealed that Fidelity’s security policies were not properly enforced, allowing users to access documents beyond their own accounts.
The breach affected not only Fidelity customers but also beneficiaries and relatives, including minors, whose data was compromised. While Fidelity notified impacted customers, it failed to alert all affected individuals, including non-customers whose information was exposed.
Fidelity stated that no customer accounts or funds were accessed during the incident and that there has been no evidence of identity theft or fraud resulting from the breach in the nearly two years since. The company has since taken steps to remediate the issue and strengthen its security protocols. The incident adds to a growing list of financial firms targeted by cyberattacks in recent years, including LPL Financial and Ameriprise Financial, which have also reported data breaches.
