Despite a decline in the total number of security incidents to more than 150, the total value lost increased by 9.5% compared to the previous quarter.
Per CertiK’s estimates, hackers have now stolen nearly $2 billion in 2024 alone, with the data showing $505.5 million lost across 224 attacks in Q1 and $687.5 million in Q2. In Q3, phishing emerged as the most damaging attack vector, with nearly $343.1 million stolen across 65 incidents.
