Telus-owned Koodo Mobile has suffered a data breach after their systems were hacked and customer data from August and September 2017 was stolen by the attackers. This information can be used by scammers to port their mobile numbers to attacker’s devices to receive 2-factor authentication codes, which could allow attackers to gain access to email and bank accounts. The company has enabled the ‘Port Protection’ feature on the affected accounts to prevent this, but feels their Port Protection feature will protect their customer’s mobile number from being used for fraudulent purposes.
