According to a Cybernews report, it has been alleged on a hacking community forum that 487 million WhatsApp user phone numbers from 84 countries, including the UK, are for sale online as part of a database which may have come from a breach. It’s been reported that the UK dataset contains the phone numbers of 11 million users and is being sold for a per-capita sum of $2,500. The advice is, if you need to check if your number or email has been stolen in a breach use a site like https://haveibeenpwned.com/. To make accounts more secure, choose strong passwords, don’t share them between accounts, use 2FA where possible, and use a good authenticator app.
