Data BreachesProsper Data Breach Impacts 17.6 Million Accounts

Posted on October 17, 2025 by Dissent

Ionut Arghire reports:

More than 17 million individuals were likely impacted by a data breach at peer-to-peer lending marketplace Prosper, data breach notification service Have I Been Pwned warns.

Prosper disclosed the incident last month, noting that hackers accessed its network and stole confidential, proprietary, and personal information from its systems.

According to the US-based company, the attackers queried its database containing customer information and applicant data to exfiltrate the information, but did not access user accounts.

“There is no evidence of unauthorized access to customer accounts and funds, and our customer-facing operations continue uninterrupted,” Prosper said.

In an undated substitute notice on its website, Prosper writes, in part:

There is no evidence of unauthorized access to customer accounts and funds, and our customer-facing operations continue uninterrupted. We have evidence that confidential, proprietary, and personal information, including Social Security Numbers, was obtained, including through unauthorized queries made on Company databases that store customer information and applicant data. We will be offering free credit monitoring as appropriate after we determine what data was affected. We continuously monitor accounts and have strong safeguards in place to protect customers’ funds.
