Despite a surge in cybercrimes, the year 2023 witnessed a significant drop in crypto thefts, with a 54.3% decline in stolen funds. In comparison to the $3.7 billion lost in 2022, the amount plummeted to a mere $1.7 billion in 2023. Intriguingly, North Korean hacker groups like Kimsuky and Lazarus Group were found to be increasingly active, accounting for nearly $1 billion in thefts.
Chainalysis Report on Crypto Thefts
According to a recent report by Chainalysis, a notable decrease in stolen funds from crypto crimes was observed in 2023, despite an increase in the number of incidents. The loss due to crypto thefts was reported to be $1.7 billion, marking a drastic fall of 54.3% from the previous year’s $3.7 billion.
Furthermore, the report highlighted an uptick in crypto attacks by North Korean hackers in 2023. Although the amount associated with these hackers fell from $1.7 billion in 2022 to $1 billion in 2023, the number of incidents escalated, reaching a peak of 20 in 2023.
The Role of DeFi Hacking
The substantial reduction in stolen funds can be attributed to a decrease in DeFi hacking, as per Chainalysis. The years 2021 and 2022 saw a surge in DeFi attacks, resulting in increased stolen funds. In 2022 alone, DeFi hacks led to a loss of about $3.1 billion. However, 2023 saw a 63.7% decrease in funds stolen from DeFi attacks, amounting to a loss of $1.1 billion.
In collaboration with Halborn, a blockchain security firm, Chainalysis identified two types of DeFi attack vectors: on-chain and off-chain. On-chain vectors are associated with vulnerabilities in the on-chain components of a DeFi protocol, such as their smart contracts, while off-chain vectors stem from vulnerabilities outside of the blockchain.
Threats and Vulnerabilities
Mar Gimenez-Aguilar, a lead security architect at Halborn, emphasized that both on-chain and off-chain vulnerabilities pose significant threats. Drawing from historical DeFi hacks, she noted that most attacks resulted from vulnerabilities in smart contracts. She also highlighted an increasing trend of attacks resulting from compromised private keys, underscoring the importance of improving security practices outside of the blockchain.
In a separate report, Chainalysis reported a 39% decrease in the total crypto value received by illicit addresses, from $39.6 billion in 2022 to $24.2 billion in 2023.
