Bank of America has around 69 million clients in over 3,800 retail financial centers and through approximately 15,000 ATMs in the United States, its territories, and more than 35 countries.
Bank of America hasn’t said how many customers were affected by the data breach, but a notification letter filed with the Attorney General of Maine on behalf of the bank said that 57,028 people were directly affected.
“Or around November 3, 2023, IMS was impacted by a cybersecurity event when an unauthorized third party accessed IMS systems, resulting in the non-availability of certain IMS applications,” the data breach notification says.
“On November 24, 2023, IMS told Bank of America that data concerning deferred compensation plans serviced by Bank of America may have been compromised. Bank of America’s systems were not compromised.”
“It is unlikely that we will be able to determine with certainty what personal information was accessed as a result of this incident at IMS.”
LockBit claims ransomware attack on IMS:
The November security breach caused certain applications and systems in IMS to be unavailable, as reported in a filing with the U.S. Securities and Exchange Commission.
On November 4th, the LockBit ransomware gang claimed to the IMS attack. They stated that their members encrypted more than 2,000 systems during the breach.
