A transparency activist shared information online Saturday indicating a massive trove of data stolen from the Chattanooga Area Chamber of Commerce is up for sale.

Emma Best, founder of nonprofit whistleblower group Distributed Denial of Secrets, tweeted Saturday morning that a ransomware firm had claimed 77 gigabytes of information allegedly taken from the chamber in the Dec. 9 hack.

The screenshot Best posted showed the hackers advertised the information as including "sample of signatures, signed internal documents, W-9, lists of employees, budget data, investor lists with phones and email, financial documents, payroll data, lots of W-2 (2016-2020), accounting files, audits, banking, payroll information, passwords "

The chamber can only say that a forensic investigation of the hack is ongoing, said Sybil Topel, vice president for marketing and communications. She added that the chamber does not store the financial or payment information of its members.
