Crypto hack counts fall but supply chain attacks reshape threat landscape
Concerns about code vulnerabilities are fading in the crypto space, but more sophisticated scam tactics are emerging as protocol security improves.
Crypto hackers stole $3.3 billion in 2025, but the number of attacks fell sharply as losses became concentrated in fewer, more sophisticated supply-chain exploits, according to new data from blockchain security firm CertiK shared with Cointelegraph.
While total losses remained elevated, the decline in incident counts and a drop in median theft sizes suggest that protocol-level security is improving, pushing attackers away from simple code vulnerabilities and toward phishing and infrastructure-level attacks.
CertiK said supply-chain breaches emerged as the most damaging threat, accounting for $1.45 billion in losses across just two incidents, including the $1.4 billion Bybit hack in February.
