Asos Hack: What You Need To Know

The online retailer has emailed customers apologising for the 'unauthorised push notification' containing an external link, adding that they should disregard the message and not click on it.

According to Charlotte Wilson, head of enterprise at global cyber-security firm Check Point, "the biggest immediate risk may be what happens next. " She says criminals know people will be searching for information online and expects there to be 'attempts to exploit that confusion. '

People should hang up the phone if they receive any calls from someone they think might be posing as Asos or another organisation, says Which? spokesperson Kat Cereda.

The consumer rights expert says they should contact the organisation themselves afterwards through separate means. It's been less than 24 hours since the notification popped up on people's phones, and there are a number of unanswered questions.

Asos said its website and app were operating 'as normal, and customers can continue to shop with confidence on ASOS as normal' as of Tuesday night. The company will provide a further update 'as soon as we have confirmed more information. ' People should visit Asos's official website directly for updates.
