Incident Details

On January 29, 2026, ShinyHunters posted data allegedly stolen from Bumble (dating app) and Match Group (parent of Tinder, Hinge, OkCupid) on a dark web leak site. ShinyHunters claimed to have stolen 10 million records across the dating apps. At Bumble, attackers used vishing to compromise a contractor account and gained brief access to internal Slack and Google Drive systems, exfiltrating approximately 30 GB of corporate files (internal documents, restricted/confidential files). Bumble confirmed member data, the app itself, and user direct messages were not exposed. Match Group investigated a related incident. Bumble’s InfoSec team detected and terminated unauthorized access quickly; external forensic investigators were engaged and law enforcement notified. A class action lawsuit was filed in Texas.
