In a tweet, Zhao, who goes by the name CZ on Twitter, said over 487 million WhatsApp phone numbers are for sale on the Dark Web. He stated that the numbers seem legit and that users should be prepared to receive phishing links and scam messages. According to a report by Cybernews, a hacker posted the numbers on a well-known hacking community forum on November 16, claiming that they were an up-to-date database of 487 million WhatsApp user mobile numbers.

The largest chunk of phone numbers belongs to the citizens of Egypt (45 million), Italy (35 million), the US (32 million), Saudi Arabia (29 million), France (20 million), and Turkey (20 million). The threat actor allegedly told Cybernews that they were selling the US dataset for $7,000, the UK for $2,500, and Germany for $2,000. The media also claimed the seller shared a sample of data with them, and they were able to confirm the validity of the numbers.
