Klue hack exposes customer data across cybersecurity firms
Market intelligence provider Klue disclosed a cyberattack that allowed hackers to exfiltrate customer data from connected cloud systems. Klue said intruders gained access on June 12 using a “compromised legacy credential” tied to an integration tool that links customers’ cloud data (such as Salesforce) to Klue. The cybercrime group Icarus claimed responsibility and threatened to publish the stolen data if a ransom is not paid. Multiple Klue customers — including Gong, Jamf, HackerOne, OneTrust, Recorded Future, Snyk, Sprout Social, Tanium, Insurity and Huntress — have confirmed data theft of business contact and some account information. Klue engaged CrowdStrike for incident response and disconnected integrations to block further access. The company has not disclosed how many customers were affected or how the credentials were obtained.
Supercell reflects on Clash Royale update mistakes
At Gamescom Dev, Supercell design lead James Back and community manager Emilia Russell reviewed three major Clash Royale updates and what the studio learned from them. They discussed removing the popular Season Shop in March 2025 (which broadened reward access but damaged player trust), adding a Level 16 progression and Hero cards in November 2025 (which split player sentiment and prompted process changes), and the launch of a successful C.H.A.O.S. Mode (introduced in March) that boosted engagement without pay-to-win concerns. Supercell emphasised the importance of involving community creators earlier, communicating changes clearly, and treating player feedback as actionable input to preserve trust and engagement.
