During a private video webinar attended by Cryptonews, Eric Jardine, the Chainalysis Cybercrimes Research Lead, provided an overview of the evolving landscape of illicit blockchain activity in 2023. Jardine highlighted the potential impact of emerging technologies, particularly large language models (LLMs), on blockchain crime. He emphasized the dual nature of AI models, which could either enhance the security of decentralized finance (DeFi) through code audits or be exploited by criminals to identify vulnerabilities in smart contracts.

Impact on DeFi and Other Sectors: Balancing Risks and Benefits

The DeFi sector remains a prime target for cryptocurrency theft, with hackers exploiting code vulnerabilities and manipulating prices to steal assets. Despite the implementation of formal audits as an industry standard, their effectiveness in preventing hacks remains uncertain. The introduction of AI into the equation introduces additional complexity, raising questions about whether it will bolster the security of smart contracts or provide new avenues for exploitation by malicious actors. Jardine’s insights underscore the need for ongoing vigilance and adaptation within the blockchain industry to address evolving threats.

Predicting Future Challenges: The Rise of AI in Romance Scams

Beyond its implications for DeFi, the proliferation of artificial intelligence presents new challenges in combating romance scams within the crypto space. Jardine expressed concerns about the potential for AI-powered models to perpetrate more sophisticated and convincing scams, exploiting victims for financial gain. Despite a decline in the total volume of scam transactions, the increased average size of romance payments suggests a higher financial impact per victim, highlighting the urgency of addressing this growing threat.
