- Crypto losses neared $2.5 billion in the first half of 2025, according to CertiK
- The total number of hacks, however, decreased in Q2 compared to Q1 this year
- The amount is almost 3% higher than what was stolen throughout 2024
Crypto siphoned through hacks, scam s, and exploits in the first half of 2025 reached $2.47 billion, according to blockchain security firm CertiK. Although the number of hacks decreased in Q2 compared to Q1 2025, the amount is almost 3% higher than what was lost throughout 2024. CertiK revealed that malicious actors returned over $187 million in the first half of 2025, bringing the amount still in the threat actors pockets to roughly $2.2 billion, a sign that most threat actors are interested in keeping the entire loot instead of a bounty.
$2.47 Billion From 344 Incidents
According to CertiK , the $2.47 billion was siphoned across 344 incidents, with wallet compromise accounting for the most losses at $1.7 billion. Phishing attacks came second, netting malicious actors $410.7 million.
Other attack vectors used to steal funds in H1 2025 include code vulnerability, access control, price manipulation, and exit scams. Ethereum recorded the highest losses at $1.5 billion. Other blockchains with significant losses include Bitcoin , Multiple Chains, BNB Chain, and Tron, with $373 million, $196 million, $132 million, and $101 million, respectively.
The Bybit hack accounted for most of the funds stolen from a single source at $1.4 billion. Cetus and Nobitex also lost a significant amount at $226 million and $89 million, respectively. Others in the top ten list include Phemex, 0xInfini, Alex Lab, MIM Spell, Cork Protocol, Bitopro, and Resupply, which lost between $9 million and $72 million.
Governments, Law Enforcement Take Note
CertiKs crypto losses report comes two weeks after the Spokane City Council voted to ban crypto ATMs to curb rising crypto scams targeting the elderly and low-income residents. It also comes three months after the City of London Police revealed that crypto scams accounted for 66% of all investment fraud cases in the UK.
With Bybit accounting for almost half of all funds lost in the first half of 2025, its to be seen whether there will be a major hack in the second half of the year.
