Allianz Life data breach exposes information of 1.1 million customers

Overview

On 19 August 2025, BleepingComputer reported that hackers stole the personal information of approximately 1.1 million individuals from U.S. insurer Allianz Life. The breach resulted from a cloud CRM compromise—later linked to a wave of attacks targeting Salesforce instances by the ShinyHunters extortion group. Allianz Life disclosed that attackers gained access to a third‑party CRM system on 16 July 2025, stealing data belonging to the “majority” of its 1.4 million customers.

What happened?

ShinyHunters reportedly exploited OAuth misconfigurations to trick employees into authorizing a malicious OAuth application connected to the company’s Salesforce environment. Once connected, the attackers downloaded customer databases, which they later leaked. The leaked records—roughly 2.8 million entries—contained names, email addresses, phone numbers, physical addresses, genders, dates of birth and tax IDs. BleepingComputer confirmed with multiple victims that the leaked information was accurate.

After the theft, ShinyHunters attempted to extort Allianz Life by emailing victims and demanding payment to prevent further leaks. Allianz Life said it could not provide additional details due to an ongoing investigation but noted that some employees were also affected.

Larger campaign

The Allianz breach is part of a broader campaign that has hit numerous high‑profile companies, including Google, Adidas, Qantas, Louis Vuitton, Dior, Tiffany & Co., Chanel and Workday. Security researchers believe the attackers have been active since early 2025, using OAuth‑based social engineering and malicious OAuth apps to infiltrate Salesforce environments.

What information was exposed?

The stolen data includes:

• Names, email addresses and phone numbers
• Physical addresses and dates of birth
• Tax IDs and other personal identifiers
• Data belonging to business partners such as wealth management firms and brokers

This information can be used for identity theft, phishing and fraud. Victims should assume their data is compromised and take precautions.

1. Monitor your accounts: Regularly check bank statements, credit card activity and insurance communications for suspicious activity.
