Singapore's crypto exchange Bitrue reported a hacker attack. Cardana (ADA) and the XRP tokens were stolen.

At approximately 1am June 27 (GMT+8), a hacker exploited a vulnerability in our Risk Control team's 2nd review process to access the personal funds of about 90 Bitrue users. The hacker used what they learned from this breach to then access the Bitrue hot wallet and move 9.3 million XRP and 2.5 million ADA to different exchanges.
