Major virtual assets, including Bitcoin (BTC), showcased a bull market and received impressive results in Q3. Behind this, the industry suffered damages amounting to $1.26 billion due to hacking and exploits. It is pointed out that infrastructure security vulnerabilities, overshadowed by rising prices, still remain the market's biggest fuse.

CryptoProwl reported on October 1st, citing a security report, that the virtual asset industry suffered a total of $1.26 billion in theft across 247 breach incidents in Q3 2026. This marks the largest single-quarter loss since early 2025. While Bitcoin surged approximately 40% during Q3 and massive funds flowed into spot ETFs, security damages also sharply increased. In September alone, $768.5 million was stolen, accounting for more than half of the total quarterly losses.

These damages were concentrated on smart contract platforms, decentralized finance (DeFi) protocols, bridges, and custody infrastructure rather than the Bitcoin base layer. The Bitcoin base layer remained relatively secure due to its proof-of-work and unspent transaction output (UTXO) model. In contrast, the surge in deposited assets within the DeFi ecosystem and complex cross-chain designs became primary targets for hackers. The $387.5 million Bitget hacking incident, among others, largely contributed to the sharp increase in quarterly losses.

Industry experts warned of a paradoxical structure where hacking attacks increase whenever a bull market arrives. As liquidity pools grew, projects rushed to deploy code to expand market share, skipping thorough security audit procedures. The introduction of new infrastructure, such as recently spreading on-chain artificial intelligence (AI) and agent-controlled wallets, also exposed vulnerabilities that existing security systems could not defend against.

There is a growing consensus that the overall price recovery in the virtual asset market does not guarantee the maturity of security infrastructure. Analysis suggests that to increase institutional fund acceptance and establish a sustainable industry, smart contract verification and asset storage security standards must be significantly strengthened.

Behind the cheers of a record-breaking Q3 rally, the painful reality of $1.26 billion in security losses has been confirmed. As institutional investors enter and the virtual asset industry prepares for a major bull market, market attention is focused on whether it can innovate its security infrastructure and lay the groundwork for rebuilding trust.
