1st Source Bank

1st Source Bank operates as a financial services institution providing banking services to its customers.
The organization is headquartered in the United States of America.
It conducts its business under the aliases 1st Source, 1st Source Financial Services, and 1st Source Bank.
As a bank, it serves individuals and businesses with its range of financial products.
Its core activities are centered on delivering traditional banking services within the U.S. market.

In June 2023, 1st Source Bank disclosed a data breach resulting from a zero‑day vulnerability in the MOVEit file transfer software it used.
The breach exposed personally identifiable information and Social Security numbers of approximately 450,000 individuals.
Upon discovery, the bank applied patches, strengthened its cybersecurity defenses, and contained the vulnerability.
It also offered complimentary credit monitoring and identity restoration services to those affected.
Earlier in May 2023, the Clop ransomware gang exploited the same MOVEit vulnerability, claiming to have downloaded a significant amount of the bank’s data and posting it on a dark‑web leak site.
These incidents underscore the organization’s reliance on third‑party file transfer tools and its exposure to supply‑chain ransomware threats.
