1st Source Bank

1st Source Bank, also referred to as 1st Source or 1st Source Financial Services, is a financial services organization headquartered in the United States. The company provides banking and financial solutions, though specific product details are not enumerated in the available information. It handles sensitive client information, including personally identifiable data and Social Security numbers, as evidenced by the nature of the data compromised in a 2023 security incident. The organization utilizes the MOVEit file transfer software for data exchanges, a tool that was exploited in a widespread cyberattack. The breach impacted approximately 450,000 individuals, indicating a significant client base across its operational regions. No explicit details are provided regarding the company's exact size, market share, or geographic footprint beyond its U.S. headquarters.

In June 2023, 1st Source experienced a data breach stemming from a zero-day vulnerability in the MOVEit system. An unauthorized third party accessed sensitive client data, leading to the exposure of personal information. Upon discovery, the bank immediately applied security patches, implemented defensive measures, and contained the vulnerability. The organization subsequently offered complimentary credit monitoring and identity restoration services to all affected individuals, demonstrating a structured incident response protocol. This event was linked to a larger campaign by the Clop ransomware gang, which targeted numerous entities using the same MOVEit flaw. The incident underscores the bank's reliance on third-party software for critical operations and its exposure to supply-chain risks. While the breach highlighted vulnerabilities, the response indicated established procedures for mitigating harm and supporting clients. Further details about the organization's ownership, subsidiary structure, or specific regulatory engagements are not available in the provided context.
