C&M Software
The recent ~$140M (R$ 800M) cyberattack on the Central Bank of Brazil services provider C&M Software is easily one of the most insane cases from this year. Six financial institutions experienced [unauthorized access](https://g1.globo.com/economia/noticia/2025/07/02/ataque-empresas-bc.ghtml) to their reserve accounts on June 30, 2025. Attackers converted fiat to BTC / ETH / USDT via Latam OTCs / exchanges. By my estimate at least $30-40M was converted to crypto. Brazilian law enforcement [has since shared](https://g1.globo.com/sp/sao-paulo/noticia/2025/07/04/ataque-hacker-quem-e-suspeito-de-entregar-acesso-ao-sistema-que-liga-bancos-do-pix.ghtml) the threat actor paid an employee at C&M only $2.76K (R$ 15K) for his corporate login and password. I'll publish theft addresses related to the incident that I found when it's ok to share them as I have been helping freeze funds and attributing unlabeled OTCs. Have not seen much coverage on the incident outside of Brazil.
