Clubhouse data breached, 3.8 billion phone numbers up for sale: Reports
- Clubhouse, an audio-only social media platform, is alleged to have suffered a data breach
- Cyber security researchers claim to have found the data up for sale on the Darknet
- Data of 3.8 billion users may have been breached
Clubhouse, an audio-only social media network, has reportedly suffered a data breach and phone numbers of 3.8 billion phone numbers are now available for sale on the Darknet — the dark underbelly of the internet, according to news reports. The claim was made by a few security researchers on Twitter.
According to Marc Ruef on Twitter, “full phone number database of #Clubhouse is up for sale on the Darknet”.
Ruef posted a screenshot of the Darknet forum where he saw the alleged Clubhouse data being sold.
The seller of the alleged Clubhouse database claims, “Clubhouse is connected to all their users’ phonebooks”. Each time a user adds a phone number to their contact list, “the phone number is automatically added into the secret database of Clubhouse”, the post claims.
Consequently, the data breach may have compromised phone numbers of people who don’t even use the app. They could have their numbers on the list by virtue of having their phone number in the contacts list of a Clubhouse user.
Clubhouse has not commented on the alleged data breach yet.
In April 2021, a CyberNews report had claimed that a Clubhouse database with 1.3 million scraped records were posted on a popular hacker forum. At the time, Clubhouse CEO Paul Davison denied the report and called it “false and misleading”.
