The person who put up the data for sale claims that there are 32 million records of users from the US within the set. It also has numbers of millions of users from Egypt, Italy, France, the UK, Russia, and India.
According to the report, the US dataset is available for $7,000, while the UK one will cost $2,500.
Cybernews said that when they contacted the seller, he shared 1,097 UK-based numbers as proof. The publication investigated the numbers and confirmed that they were all from WhatsApp accounts.
However, the hacker did not specify how they obtained the data.
Such information is often used for cyber crimes like smishing and vishing, both of which involve sending the user a text message and asking them to click on a link. The user is then asked to provide their credit card or other personal details.
This is not the first instance that a Meta-owned platform has been hit by a data breach. Last year, the personal data of over 500 million Facebook users, including 6 million records from India, was allegedly leaked. The leaked data then included phone numbers and other details.
