The Lyon Firm is investigating FlexBooker data breach claims on behalf of victims nationwide. When a company collects and stores your information, they have a duty to protect it. Should they fail to provide basic security, and your data is stolen, you may file a lawsuit to gain compensation.

According to recent reports, more than three million FlexBooker users have had their data stolen in a December 2021 cyberattack. The same alleged hackers (calling themselves Uawrongteam) are offering data collected from two other entities: racing media organization and Redbourne Group’s rediCASE case management software.

A reported data dump appears to be from FlexBooker, a popular tool for scheduling appointments and synchronizing employee calendars. FlexBooker customers use the service to schedule appointments with various businesses, including accountants, barbers, doctors, mechanics, lawyers, dentists, gyms, salons, therapists, trainers, spas, etc.

Those responsible for the FlexBooker attack have shared links to files containing sensitive information like payment forms, photos, driver’s licenses, phone numbers, emails, passwords and other IDs.

FlexBooker recommends users to stay vigilant and review account statements and credit reports for suspicious or fraudulent activity. The Lyon Firm urges victims to act quickly to protect themselves and contact an attorney.

According to the Have I Been Pwned data breach website, the FlexBooker data breach compromised data of more than 3.7 million accounts.
