Have you had your 'credentials stuffed'?
O2 customer data has been found for sale on the 'dark web'. It's bad enough discovering that your mobile phone account has been hacked but that's only the start of it - 'credential stuffing' is when hackers try your compromised email address and password combination on other sites, like Ebay, Gmail and PayPal. Before you know it all your accounts are being cleaned out and then used to defraud other customers.
One solution is to ensure that you use a different email address everywhere you sign-up. Using a tool like 'Me and My ID' you can create hundreds of aliases, which are easy to remember because they contain the brand's name e.g. [email protected]. We re-direct all your marketing email to your main email address.
An added benefit is that when - not if - this alias email address is stolen, and you start to receive SPAM, you can block it via our console.
