If you have been the victim of a data breach, you should stay alert to scammers using phishing messages, emails and calls asking you to click links or share sensitive information.    A data breach occurs when information held by an organisation is stolen or accessed without authorisation. To find out if you have been affected, we recommend contacting the organisation using their official website or social media channels - do not use the links or contact details in any messages you have been sent.    For more guidance on how to spot phishing messages, what to do if your data has been breached, and how to recover a hacked account ⬇️ https://lnkd.in/dmZnKNF
