Fidelity data breach compromises more than 77,000 customers

One of the largest financial services and asset management companies has just been breached.

According to a new notice filed with the Office of the Maine Attorney General, Fidelity Investments was targeted in a data breach. More than 77,000 customers have had their sensitive personal information compromised.

"Between August 17 and August 19, a third party accessed and obtained certain information without authorization using two customer accounts that they had recently established," Fidelity said in a letter sent to affected customers.

Upon noticing the breach on August 19, Fidelity says it immediately cut the unauthorized party's access to its systems.

It's unclear as to what specific personal data was stolen. It's also unclear how a bad actor was able to access private data tied to 77,099 customer accounts by "using two customer accounts that they had recently established." 

According to Fidelity, customers' accounts were not compromised. The company also shared that those who were affected make up a small subset of its more than 50 million customers.

Fidelity will be providing the affected customers with two years of credit monitoring services.

This Fidelity data breach marks yet another instance of users' data being compromised just in this week alone. Comcast, MoneyGram, and the Internet Archive all notified customers and users that their data had been stolen in a data breach.
