Lazarus Group is a North Korean state-sponsored advanced persistent threat (APT) actor, also tracked as APT38, TraderTraitor, BlueNorOff, Hidden Cobra, and ZINC, operating under the Reconnaissance General Bureau (RGB) of the Korean People's Army. Active since approximately 2009, the group has stolen an estimated $6.75 billion in cryptocurrency through targeted attacks on exchanges, bridges, and blockchain companies, using stolen funds to finance North Korea's weapons programs and circumvent international sanctions. The U.S. Department of Justice has indicted three named members, and OFAC placed the group on the Specially Designated Nationals (SDN) list in April 2022.

Velodrome Finance is an automated market maker (AMM) and decentralized exchange (DEX) launched on June 2, 2022, on the Optimism Layer 2 network. It is a fork and improvement of Andre Cronje's Solidly Exchange, implementing a ve(3,3) governance and liquidity incentive model. The protocol has experienced three documented security incidents: an insider theft of $350,000 by a team member in August 2022, a DNS/frontend social-engineering attack in November–December 2023 resulting in approximately $250,000 in user losses, and a second DNS hijacking in November 2025 attributed to a NameSilo registrar insider, resulting in estimated losses of $700,000–$1,000,000. Smart contracts have not been directly exploited; all monetary losses have stemmed from front-end and operational security failures.

Garden Finance is a cross-chain Bitcoin bridge protocol launched in 2023 by former Ren Protocol developers, using Hash Time Locked Contracts (HTLCs) and an intents-based solver network to enable atomic swaps across Ethereum, Solana, Arbitrum, Base, and other chains. On October 30–31, 2025, one of its largest solver operators was compromised via a leaked private key, resulting in approximately $11.4 million in stolen assets that were subsequently laundered through Tornado Cash. Prior to the exploit, blockchain investigator ZachXBT alleged that over 80% of the protocol's recent fee revenue was derived from laundering funds stolen in the February 2025 Bybit hack, which the Lazarus Group (DPRK) perpetrated for approximately $1.4 billion.

Wasabi Protocol is a decentralized perpetual futures and leveraged trading platform for memecoins and long-tail assets, deployed on Ethereum, Base, Berachain, and Blast. On April 30, 2026, the protocol suffered a critical multi-chain exploit in which a compromised admin deployer key was used to execute malicious UUPS proxy upgrades across core contracts, draining over $5 million in user funds. Security firm BlockSec reported that the attacker's wallets had been funded via Tornado Cash, and on-chain investigator ZachXBT publicly criticized the protocol for single-EOA admin control, absence of a timelock or multisig, and alleged misappropriation of project funds on influencer marketing.

Noones is a peer-to-peer cryptocurrency trading platform targeting Africa and the Global South, founded and initially led by Ray Youssef, co-founder of the now-defunct Paxful. In January 2025, the platform suffered an $8 million hot-wallet exploit that was concealed for nearly three weeks before on-chain investigator ZachXBT publicly exposed the breach. Compounding platform risk, Youssef was subsequently indicted by the DOJ in early 2026 on federal AML charges stemming from his leadership of Paxful, and stepped down as Noones CEO shortly thereafter.

Crypto.com is a Singapore-headquartered centralized cryptocurrency exchange founded in 2016 (originally as Monaco) by Kris Marszalek, Bobby Bao, Gary Or, and Rafael Melo. The platform has been subject to multiple serious security incidents, including a confirmed January 2022 hack in which $34 million was stolen via a 2FA bypass and laundered through Tornado Cash, and an alleged 2023 data breach linked to the Scattered Spider hacking group that the company did not publicly disclose to affected users. Blockchain investigator ZachXBT has publicly accused Crypto.com of governance manipulation and tokenomics fraud, citing the March 2025 reissuance of 70 billion CRO tokens that had been permanently burned in 2021, and the company's controversial 2020 forced swap from its original MCO token to CRO at unfavorable rates.

Sui is a Layer 1 blockchain developed by Mysten Labs, launched in May 2023 and built on the Move programming language. The network suffered one of the largest DeFi exploits of 2025 when Cetus Protocol — its primary DEX — was drained of approximately $223 million in May 2025, triggering a controversial emergency validator vote to freeze and reclaim stolen funds that exposed deep centralization concerns. Separately, ZachXBT investigated a $29 million SUI token theft in late 2024 involving Tornado Cash laundering and subsequently announced in July 2025 that he would no longer take Sui ecosystem cases due to inadequate incident-response infrastructure and lack of support from the ecosystem.
