US Cyberattacks Escalate: Allianz Life, Microsoft, and UnitedHealth Breaches Expose Millions

A cyberattack on Allianz Life has exposed personal data of 1.1 million customers, including names, addresses, phone numbers, and email addresses. This comes as part of a string of high-profile breaches impacting US companies, including Microsoft and UnitedHealth Group. Allianz Life will offer impacted individuals two years of identity monitoring services.

A cyberattack at U.S. insurance firm Allianz Life in late July compromised the personal data of 1.1 million customers, according to breach notification site Have I Been Pwned [1]. The breach, which occurred on July 16, 2025, exposed names, addresses, phone numbers, and email addresses of affected individuals. Allianz Life previously reported that hackers stole personal information from most of its 1.4 million U.S. customers, financial professionals, and select employees.

The attack used social engineering techniques to gain access to a third-party cloud-based CRM system used by Allianz Life. The company has stated that there is no evidence of intrusion into its core systems, including its policy administration platform. Allianz Life is contacting affected individuals and providing two years of identity monitoring services to help mitigate potential risks.

This breach is part of a broader wave of high-profile cyberattacks targeting global companies, including Microsoft and UnitedHealth Group. In 2022, a cyberattack on UnitedHealth's technology division affected 192.7 million people, making it the largest healthcare data breach in U.S. history [2]. Meanwhile, hackers infiltrated Microsoft's on-premises SharePoint servers in July 2025, hitting more than 100 organizations, including U.S. government agencies, and raising concerns about identity security [3].

Allianz Life joins a growing list of companies that have been targeted by cybercriminals in recent months. The company's response to the breach, including the provision of identity monitoring services, is a step in the right direction to help protect the personal information of its customers.
