Crypto and Web3 security incidents led to over $801.3 million in losses across 144 incidents in Q2 2025. CertiK reported that this reflects a 52.1% decrease in value lost from the previous quarter.<\/p>\n
The quarter also saw 59 fewer incidents during this period.<\/p>\n
Phishing was the most damaging attack vector, as it saw $395 million being stolen across 52 incidents. Code vulnerabilities followed suit and recorded $235.8 million in losses across 47 incidents.<\/p>\n
In its latest report, CertiK said<\/a> that Ethereum saw the highest number of incidents. The network recorded 70 hacks, scams, and exploits, resulting in $65.4 million in losses for the quarter.<\/p>\n Additionally, funds worth $181 million were recovered, which brought the adjusted losses for the second quarter to $620.4 million. The average loss per incident was $4.3 million, while the median was around $104,000.<\/p>\n Zooming out, the blockchain security firm also reported total losses of $2.47 billion across 344 incidents for the first half of 2025. Wallet compromises were the costliest during this period, as these breaches accounted for $1.71 billion in losses across 34 incidents. Next up was phishing, with $410.7 million stolen across 132 incidents, which made it the most frequent attack type so far this year.<\/p>\n So far this year, Ethereum recorded 175 incidents in H1, resulting in $1.63 billion in losses. A total of $187.3 million was recovered in the first half of the year, pushing the adjusted total losses to $2.29 billion. Meanwhile, the average loss per incident for H1 was $7.13 million, with a median loss of $89,026.<\/p>\n CertiK noted that while headline figures suggest worsening crypto security, two incidents alone accounted for around $1.78 billion of 2025\u2019s losses \u2013 the Bybit hack and the Cetus Protocol breach.<\/p>\n Hackers exploited<\/a> Bybit\u2019s cold wallet infrastructure in February 2025 by altering transaction logic and masking interfaces, which enabled them to steal over $1.5 billion in Ether. North Korea\u2019s notorious state-sponsored hacking entity, the Lazarus Group, was responsible for it.<\/p>\n Besides, Sui-based Cetus, on the other hand, suffered<\/a> an exploit in an overflow check within the project\u2019s liquidity calculation function, which resulted in $225 million in losses in May.<\/p>\n Without these two incidents, total losses would be $690 million, which essentially indicates that the broader security trend may not be as severe as the raw figures imply.<\/p>\n The post $181M Recovered From Hackers, But Crypto Still Lost $620M in Q2<\/a> appeared first on CryptoPotato<\/a>.<\/p>","protected":false},"excerpt":{"rendered":" Crypto and Web3 security incidents led to over $801.3 million in losses across 144 incidents in Q2 2025.
