DeusEx 1,895 In one of Brazil’s largest cyberheists, hackers stole $140 million from six major banks by bribing an IT insider—a developer at C&M, a firm that builds critical financial infrastructure linking banks to Brazil’s Central Bank. Date of Attack: June 30, 2025 Insider Involved: João Nazareno Roque, a C&M employee Payment for Betrayal: Just $920 for initial access + $1,850 for executing commands Arrest: Roque was captured on July 3, 2025, in São Paulo after attempting to evade detection (e.g., swapping phones every 15 days). How the Hack Unfolded 1️⃣ The Recruitment: Hackers met Roque near a bar, convincing him to collaborate. They communicated via Notion, directing him to manipulate C&M’s systems. 2️⃣ The Insider’s Role: Roque provided his credentials and executed unauthorized transactions. Attackers exploited PIX, Brazil’s instant-payment system (used by 76.4% of the population). 3️⃣ The Laundering: $30–40 million was converted to crypto (BTC, ETH, USDT) via Latin American exchanges/OTC platforms. One bank alone lost $100 million. Why This Attack Matters 🔴 Supply Chain Weakness: Hackers targeted a third-party vendor, not the banks directly.🔴 Social Engineering > Hacking: No technical exploits—just bribes and manipulation.🔴 PIX as a Weapon: Brazil’s real-time payment system became the hackers’ exit route. The Fallout & Investigation Three active probes by Brazilian police (hackers’ identities still unknown). C&M’s Defense: Claims its systems were "secure" and blames "pure social engineering." Industry Alarm: Questions arise about insider-risk protocols at financial tech providers. Key Takeaways ✅ Third-Party Risk is Exploding: Vendors with bank access are prime targets.✅ Insiders Are the New Attack Vector: A $920 bribe can cost millions.✅ Instant Payments = Instant Theft: PIX’s speed helped hackers vanish funds.
