Hot Wallet

Sportsbet.io is a cryptocurrency gambling and sports betting platform operated by mBet Solutions N.V. under the Yolo Group umbrella, licensed in Curaçao. On June 22, 2024, blockchain investigator ZachXBT publicly identified that the platform's hot wallets were drained of approximately $3.5 million in USDT and TRX, attributing the attack to the same threat actor who hours later stole an estimated $55 million from Turkish exchange BtcTurk, with stolen funds allegedly commingled between both hacks. The platform has drawn ongoing scrutiny for operating in regulatory grey markets, serving users in jurisdictions where it holds no local license, and for systemic user complaints involving account closures and fund seizures following wins. Yolo Group founder Tim Heath confirmed in 2025 that the brand is being wound down in favor of fully regulated markets.

BtcTurk is Turkey's oldest and largest centralized cryptocurrency exchange, founded in 2013 in Istanbul. The exchange has suffered two major hot wallet breaches in 14 months — approximately $55 million stolen in June 2024 and approximately $48–$49 million in August 2025 — both attributed to private key compromise, establishing a pattern of repeated critical security failures. Despite operating under Turkish regulatory frameworks (CMB and MASAK) and maintaining cold wallet protections, the exchange's inability to prevent a second near-identical attack within a year raises serious concerns about the adequacy of its security controls.

Metawin is an offshore crypto casino and gaming platform licensed under the Anjouan (Comoros) gaming authority, operated by Asobi N.V. from Curacao, and founded by Richard 'Skel' Skelhorn. On November 3, 2024, the platform suffered a significant hot wallet exploit across Ethereum and Solana blockchains resulting in approximately $4 million in stolen funds, with blockchain investigator ZachXBT tracing the stolen assets to KuCoin and a nested HitBTC service across more than 115 attacker-linked addresses. The CEO subsequently claimed to have personally covered the losses, restoring withdrawals for approximately 95% of affected users, though the platform's offshore jurisdictional status and the underlying security vulnerability raise ongoing concerns.

BitoPro is a Taiwanese centralized cryptocurrency exchange operated by BitoGroup, serving over 800,000 users with TWD (New Taiwan Dollar) fiat on/off-ramps. On May 8, 2025, the exchange suffered an approximately $11.5 million hot wallet theft attributed to North Korea's Lazarus Group via a social-engineering and AWS-token-hijacking attack. The exchange did not publicly disclose the breach for approximately 25 days, only confirming the incident after on-chain investigator ZachXBT flagged suspicious outflows on June 2, 2025.

CoinEx is a centralized cryptocurrency exchange that suffered a major hot wallet breach on September 12, 2023, with losses estimated between $54 million and $70 million across multiple blockchains. On-chain investigators ZachXBT and Elliptic attributed the attack to the Lazarus Group (TraderTraitor), a North Korean state-sponsored threat actor, based on wallet address overlap with the contemporaneous Stake.com hack. Stolen proceeds were subsequently laundered in part through the Sinbad Bitcoin mixer, which was sanctioned by the U.S. Treasury's OFAC on November 29, 2023.
