In the first half of 2026, losses from hacker attacks on cryptocurrency projects have exceeded $1 billion, with the number of verified attack incidents reaching a record high for the same period in history, described as "the half-year with the most hacker attacks on record." However, in terms of value, overall losses remain lower than the same period last year, mainly because a $1.5 billion attack incident occurred at Bybit in 2025, raising the baseline.
Odaily, Web3 security firm CertiK has released the "Hack3D: First Half of 2026 Report." The report shows that the Web3 ecosystem experienced 344 security incidents in the first half of 2026, with cumulative losses of approximately $1.32 billion. Although this figure represents a 46.8% decrease compared to the same period last year, excluding the impact of the $1.45 billion security incident involving Bybit, the scale of losses in the first half of this year actually increased by approximately 28% year-on-year, indicating that the overall security environment in the industry has not materially improved.The report points out that wallet theft has become the attack type causing the greatest financial loss, accounting for approximately $450 million in losses in the first half of the year. Meanwhile, although the number of phishing attacks fell by more than 50% year-on-year, the loss amount only decreased by approximately 10.8%, reflecting that attackers are shifting towards high-net-worth individuals and institutional targets, carrying out more targeted high-value attacks.Furthermore, code vulnerabilities remain the most frequent type of attack, with 204 related incidents. CertiK believes that attackers are increasingly targeting long-running legacy smart contracts that lack re-audits. The report also shows that mega-attacks continue to dominate industry losses, with the Kelp DAO and Drift Protocol incidents alone causing approximately $577 million in losses, accounting for 44% of the total losses in the first half of the year. Looking at the number of incidents, the impact of single attacks, and the changing attack patterns, the Web3 industry is facing more complex and continuously escalating security challenges.
: Cardano wallet service provider SecondFi has released an update on the security incident recovery progress, stating that EMURGO has established an asset recovery fund to return assets to users affected by the attack.SecondFi stated that emergency measures have been taken to protect and restore access to some assets. The team is currently discussing appropriate custody mechanisms with Intersect to ensure the safe return of assets to users.Furthermore, SecondFi is collaborating with a Cardano community-led working group to advance the on-chain recovery plan. Due to the recovery plan being more complex than initially expected, the overall recovery time may exceed the previously estimated two weeks.
: In response to the recent security incident involving Cardano ecosystem project SecondFi, SlowMist founder Cos said on social media that after continuously monitoring the relevant on-chain data, he believes that if the two addresses starting with "addr1q" are both controlled by the attacker, the actual losses for SecondFi users may have exceeded $20 million.Cos stated that based on on-chain behavior analysis, the aforementioned addresses are highly likely related to the attacker, involving stolen assets potentially exceeding 129 million ADA and other tokens.Previously, SecondFi disclosed that this security incident affected approximately 16 million ADA, stating that the issue originated from the web wallet generation software.
According to analysis by BlockSec Phalcon (@Phalcon_xyz), Aztec Network's RollupProcessorV3 contract was attacked, resulting in losses exceeding $2.15 million. The root cause is that `numRealTxs` was not effectively bound to the transaction set enforced by the ZK proof, causing a deviation between the proof verification path and the L1 settlement logic's interpretation of the transaction list.The attacker exploited this vulnerability to move real deposits to slots not processed by the settlement logic, bypassing the `decreasePendingDepositBalance()` function. By creating unbacked private balances out of thin air, they were able to withdraw funds through the normal settlement process. A total of seven assets were involved.
According to Specter (@SpecterAnalyst), Humanity Protocol has been hacked, with losses exceeding $31 million. Funds are still being transferred, and the attacker is converting H into ETH.
Wallets associated with or interacted with Humanity Protocol are being compromised. Currently, over 17 wallets holding H tokens have been stolen, with total losses exceeding $19 million. The cause of the theft remains unclear, but the attack pattern suggests that the affected wallets may share a common risk exposure related to Humanity Protocol.
On-chain investigator ZachXBT stated that THORChain appears to have been attacked on the Bitcoin, Ethereum, BSC, and Base networks, resulting in losses exceeding $7.4 million.
According to on-chain detective ZachXBT, THORChain has suffered an attack across multiple chains, resulting in losses exceeding $7.4 million.
