Cryptographic hacks are falling in the first half because the losses in the first half reached USD 2.5 billion

Losses in cryptographic hacks, exploits and fraud increased to $ 2.47 billion in the first half of 2025, but in the second quarter there was a decrease in the total number of hacks, says Certik Blockchain School.

Over USD 800 million was lost in 144 incidents in II2 compared Until the previous quarter with 59 smaller hacker incidents, Certik he said In the report from Tuesday.

In total, in the first half of 2025, for over $ 2.47 billion of losses due to hacks, fraud and feats, which is an raise of almost 3% compared to $ 2.4 billion in 2024.

However, considering that over $ 187 million returned in the first half of the year, Certik said that the corrected sum is closer to $ 2.2 billion.

Most losses of two incidents

Despite the raise in losses, Certik said that it does not necessarily “suggest the deteriorating security landscape”, because the lion’s share of losses results from only two incidents against the bull’s cryptocurrency and a CET protocol worth $ 1.78 billion in total.

Attacks used the gaps in the icy portfolio infrastructure, dustning $ 1.5 billion in Ether (ETH) on February 21, while the Cetus protocol, the main decentralized exchange of blockchain sui, suffered $ 225 million of hacking on May 22.

“Without these events, total losses in 2025 would be $ 690 million, which indicates that a wider trend may not be as serious as the raw data suggest,” said Certik.

Violent phishing attacks, Ethereum aimed at

Phishing is currently the largest number of security incidents so far, with 132 security incidents and $ 410 million stolen.

In general, the portfolio compromises were the most exorbitant attack vector in the first half of 2025, with a report, with over $ 1.7 billion in 34 incidents.

“Since phishing campaigns are becoming more deceptive, it is necessary for users to accept strong safety habits: Avoid clicking unknown links, checking the authenticity of the domain twice, enable multifactor authentication and consider using hardware wallets for storing keys,” Certik said.

Blockchain Ethereum was one of the more popular goals, corresponding to 70 hacks, fraud and feats compared to 98 in the first quarter.

“The domination of Ethereum in decentralized financial activities and an intelligent agreement makes it an attractive goal, and billions of dollars blocked in the protocol,” said Certik in a security report for Q1.

Required strict safety standards

In addition to security incidents, Certik said that the first half of 2025 was marked by significant global regulatory and market changes, which probably “shape the future of the industry.”

In the United States, President Donald Trump initiated reforms in the Securities and Stock Exchange Commission, in which the agency abandoned many enforcement activities against cryptographic companies and implements other legislation related to cyrrypto.

Meanwhile, the legislative council of Hong Kong adopted the Stablecoin Act, paving the way to the regulated frames and regulatory framework for the Union for Crypto, Mika, entered into force on December 30.

“Together, these changes signal both the growing institutional interest and the maturing regulatory environment,” said Certik.

“When the new capital and participants fall into space, maintaining rigorous security standards will be more important than ever,” the company added.
