Data breaches

The company's latest filing provided a brief timeline of the incident that was uncovered on Dec. 20.

The title company was also attacked in 2019 and joins Fidelity National and Mr. Cooper among recent victims.

To make amends to former and current borrowers, Mr. Cooper is footing the bill for two years of complimentary identity protection services.

While ransomware group Alphv/Blackcat claims to have orchestrated the incident, title insurance company Fidelity National Financial has not yet stated whether confidential data was compromised.

The bank suffered its third breach in three years, this time by virtue of a vulnerability in Progress Software's file-transfer system. But Flagstar is only one of many such victims.

The customers were affected by an incident involving a Progress Software program used by Sovos Compliance.

The incident occurred in November 2020 when an unauthorized party gained access to company systems and deployed ransomware, resulting in compromise of employees' personal information.

The case involved incidents occurring in early 2021, when an unauthorized individual obtained access to files containing personal identifiable information of consumers.

HomeTrust Mortgage disclosed customers' names, addresses and Social Security numbers may have been compromised in the incident.

Tech executives say that improperly incorporating new software with existing systems can result in breaches and leaked personal identifiable information.
