Blockchain security firm CertiK reported that crypto firms and users have lost nearly $2.7 billion to security incidents this year through September. North Korea-linked thefts alone exceeded $1 billion. September was the costliest month, with losses reaching $766.5 million, largely due to the $387.5 million Bitget breach and the $318.7 million Liquid Network incident. The five largest incidents account for almost 59% of the total losses, highlighting a significant concentration of damage from a few major attacks.
