According to CyberNews, the combined Clubhouse-Facebook database includes names, phone numbers and other data, and is listed on an underground forum for $100,000 for all 3.8 billion entries, with smaller chunks of data available for less.
"Breaches like these often get sold at a discount because the ones who stole the data don't know what to do with it. In some cases, intelligence agencies will buy them if they have targets of interest on those platforms," Bambenek said.
"Likely the biggest use will go into the secondary consumer data market for those who want to build profiles for specific ad targeting."
Beyond immediate ramifications of the enhanced data falling into the wrong hands, Archie Agarwal from ThreatModeler pointed out that as these leaks continue, it will enable threat actors to create incredibly rich profiles of targets.
"As we share more and more personal information across an ever-growing list of social-media platforms, combining data gleaned from this type of scraping, together with leaked breach information and leveraging big-data analytics to mine it, could potentially reveal previously hidden information and behaviors on users."
While the infosec community is alarmed by the prospect of all that data floating around, Roger Grimes from KnowBe4 doesn't expect the seller of the combined Clubhouse-Facebook data to get much finanical gain out of the deal.
