New Delhi, July 24 Nearly four million phone numbers of Clubhouse users have been allegedly leaked and are 'up for sale' on the Dark Web.
The dataset of the popular audio chat app only shows mobile numbers and no other information.
"A database of 3.8 billion phone numbers of #Clubhouse users is up for sale on the #Darknet," leading cybersecurity expert Jiten Jain wrote on Twitter.
"It also contains numbers of people in user's phonebooks that were synced. So chances are high that you are listed even if you haven't had a Clubhouse login," Jain added.
However, the audio chat app was yet to confirm the alleged data leak.
According to independent security researcher Rajshekhar Rajaharia, the hacker is selling alleged Clubhouse data which contains only mobile numbers without names.
"There are no names, photos or any other details available. This list of phone numbers can be generated very easily. Data leak claim appears fake," Rajaharia told .
In February this year, researchers at Stanford University in the US have warned that the app may be leaking users' audio data to the Chinese government.
The Stanford Internet Observatory (SIO) claimed that Agora, a Shanghai-based provider of real-time engagement software, supplies back-end infrastructure to the Clubhouse app.
Recently, Clubhouse announced that it is now out of beta and open to everyone.
The company said that it has removed its waitlist system so that anyone can join the platform hassle-free.
The company said it has added 10 million people to the community since its launch on Android in mid-May.
