Crypto crime in 2025 has become really high, as Chainalysis shows middle-year data putting stolen amount more than $2.17 billion. This could make it an most violent year so far. Groups like North Korea’s Lazarus Group took $1.5B from ByBit through a phishing attempt that was like a vault break-in in February. In the June, Nobitex from Iran lost between $90–100M because some geopolitics hackers got in; they also leaked source code of Nobitex just to make it more messy for everybody. Right after updating in July, CoinDCX in India lost $44M after sneaky attack through their server exploit.

The attackers keep using same methods as before: they get engineer keys set up hot wallets wrongly and use multi-signature wallets that one wrong person can break. Security problems still happen as in November when Balancer lost $120M through contract mistakes. Exchanges continue to do less audits and not enough bug bounties, so people have to use self-custody hardware wallets and air-gapped transactions for safety.

Some positive things exist. On-chain detectives and white-hat hackers are stopping fraud more, helping to return around 20–30 percent of crypto lost, using exchanges to freeze and reward people. Trump government stopped the SEC cases with Ripple, and Coinbase and new GENIUS Act is helping stablecoin users in bankruptcies. All these disasters show: centralization is risky, decentralization is necessary. This year is very stressful and making better operational security happen.
