Shaw Communications Inc. has confirmed that the data of some 15,000 customers was left exposed on the internet, though the company says there is no evidence any of it was misused. The data breach was discovered when two cybersecurity researchers contacted Shaw to inform the company that customer data from Shaw’s Freedom Mobile was left unencrypted on the internet, as first reported by TechCrunch. According to an emailed statement from Freedom Mobile Tuesday, the affected customers were those who had “opened or made changes to their accounts at 17 Freedom Mobile retail locations from March 25 to April 17, and any customers who made changes or opened accounts on April 16.” The company said an external third-party vendor, Apptium Technologies, is now conducting an investigation alongside Shaw’s own investigation. In addition to those that changed or opened their accounts at those locations, Shaw said some data from people who applied for service “but didn’t complete a transaction” was also exposed. The company has filed a report with the Officer of the Privacy Commissioner.
