Ameriprise sued after breach allegedly put customer financial data at risk

Ameriprise data breach class action overview:

• Who: A former Ameriprise Financial client is suing the financial services company.
• Why: The plaintiff claims Ameriprise failed to properly secure and safeguard the personal information of herself and other clients.
• Where: The Ameriprise class action lawsuit was filed in Minnesota federal court.

Ameriprise Financial is facing a class lawsuit alleging it failed to properly secure and safeguard the personal information of its clients from hackers.

Plaintiff Betty Lackey claims Ameriprise failed to protect her and other clients’ personally identifiable information (PII) from a data breach by the ShinyHunters ransomware group that allegedly occurred in March.

Lackey argues Ameriprise has yet to notify victims of the data breach that their PII — including names, addresses, dates of birth, account information, payment card information, authentication information, financial transaction information, contact information and Social Security numbers — was compromised and that they are at a significant risk of identity theft.

“Most, if not all, class members have no idea that their private information had been compromised, and that they continue to be at a significant risk of identity theft and various other forms of personal, social and financial harm,” the Ameriprise class action lawsuit says.

Ameriprise allegedly failed to adequately enhance data security practices

Lackey claims Ameriprise failed to adequately enhance its data security practices to avoid a potential breach despite being aware that companies in the financial industry were susceptible targets.

“Ameriprise knew or should have known that its electronic records would be targeted by cybercriminals,” the Ameriprise class action lawsuit says.

Lackey wants to represent a nationwide class of individuals who had their PII impacted as a result of the data breach. She demands a jury trial and requests declaratory and injunctive relief and an award of actual, statutory and punitive damages for herself and all class members.

In 2024, Ameriprise was sued over allegations it breached its fiduciary duty by recommending retail and investment customers hold funds in “cash sweep accounts” that benefit the bank rather than its customers.
