According to CertiK’s remarks at the DC Blockchain Summit, supply chain attacks caused the largest crypto losses, while phishing remained the most frequent incident type and prompted calls for stronger disclosure and response frameworks.
In an official statement shared at the DC Blockchain Summit, blockchain security firm CertiK said supply chain attacks were responsible for more than $1.45 billion in crypto-related losses, while its 2025 Skynet Hack3D report identified 240 phishing attacks as the most frequent incident type last year. CertiK Chief Business Officer Jason Jiang said the findings show persistent weaknesses across crypto infrastructure and called for regulation that supports responsible disclosure and faster incident response.
