2026.has already recorded over $2.17 billion in stolen cryptocurrency, with major platforms like ByBit and CoinDCX suffering large-scale attacks.
The year's biggest security threats include exchange vulnerabilities where hackers target hot wallets to drain funds within minutes, and smart contract flaws that led to over $1 billion in losses through reentrancy attacks, missing access checks, and arithmetic overflows. BEV (Block Extraction Value) related issues have caused over $540 million in losses as attackers use bots to manipulate mempools and distort prices. While Bitcoin and Ethereum remain secure against 51% attacks due to their size, smaller chains remain vulnerable to consensus attacks and routing manipulations. The persistent large-scale losses indicate that while some crypto security areas improve, attackers continue finding success across multiple attack vectors, with the average hack size doubling compared to 2025.
