According to Cointelegraph, Fidelity recently submitted a document to the Maine Attorney General, stating that 77,099 of its customers were affected by the data breach, which is only a small part of its total 51.5 million customers.
Fidelity said an attacker gained access to customer names and other personally identifiable information through two recently created customer accounts between August 17 and 19. Fidelity first discovered the breach on August 19 and immediately terminated the unauthorized access.
The company said it had worked with “external security experts” to resolve the issue and stressed that no third party had accessed any Fidelity accounts.
Fidelity has pledged to provide affected users with two years of free credit monitoring and identity restoration services to help detect any unusual activity that could affect a user's personal finances.
