Odaily Planet Daily News: Earlier on Wednesday, the bridge service of Bitcoin DeFi application ALEX Lab was attacked by suspected private key leakage, resulting in the loss of more than $4.3 million in its various tokens. Security research firm CertiK said that the attacker may have mastered the private key that controls the ALEX XLink bridge. The hacker transferred more than $300,000 worth of BTC, $3.3 million worth of stablecoins, and $75,000 worth of Sugar Kingdom (SKO) tokens. ALEX developers confirmed the hack on X earlier in European time, claiming that they knew the identity of the attacker. The team promised a 10% bounty and required the hacker to return 90% of the stolen funds. (CoinDesk)
