Chris Larsen is the co-founder and Executive Chairman of Ripple, one of the most prominent figures in the XRP ecosystem. On January 30, 2024, attackers drained an estimated 213–283 million XRP (valued at $112.5–$150 million) from his personal cryptocurrency accounts — not Ripple corporate wallets — in what became the largest individual crypto theft of 2024. A U.S. government forfeiture complaint filed in March 2025 linked the breach to the 2022 LastPass password manager hack, alleging that private keys had been stored in an online vault subsequently compromised by attackers.

C&M Software (also styled CMSW) is a Brazilian financial technology company authorized by the Banco Central do Brasil to provide connectivity between smaller financial institutions and Brazil's national payment infrastructure, including the PIX instant-payment system. On June 30, 2025, hackers exploited credentials sold by an insider employee to drain approximately R$800 million (roughly USD 140–148 million) from reserve accounts of at least six financial institutions, in what became Brazil's largest recorded banking cyberattack. A portion of the stolen funds—estimated at USD 30–40 million—was subsequently laundered through Latin American OTC desks and crypto exchanges using Bitcoin, Ethereum, and Tether USDT, with on-chain investigator ZachXBT playing a central role in tracing and partially freezing the laundered assets.

Strike (operated by Zap Solutions, Inc.) is a Bitcoin and Lightning Network payments application founded by Jack Mallers. The platform has faced scrutiny over a 2023 data breach it initially denied, the use of Tether (USDT) as a backing for purported USD cash balances for non-US users, and a 2026 proposed merger with Twenty One Capital (XXI) that raises serious conflict-of-interest concerns given Mallers serves as CEO of both entities.
