As the crypto world blossomed into a fantastic financial jump, so did the homing in on hacker attacks against exchanges and digital wallets. If from early penetrations, for example, the breakdown of mt. Gox in 2014 to high-profile demonstrated shows (Wazir, Traveler Expansion, and HTX hacks); these occasions mirror the fundamental weaknesses in the cryptocurrency currency environment. Hackers took an astounding $1.7 billion in cryptocurrency from platforms through 2023, with 60 of those attacks attributed to groups from North Korea that might help finance nuclear weapons programs [1]. The vulnerabilities these cybercriminals exploited from ransomware and DeFi to targeted digital currency thefts highlighted the need for more robust security measures across crypto verticals. 83% of financial industry leaders have elevated cybersecurity to a priority with significant repercussions to their business [2]. There has been a new pattern-bursting for new technologies like blockchain and artificial intelligence (AI) that are highly beneficial for advertising the crypto ecosystem. The decentralized structure of blockchain, its immutable records, and transparency ensure robust data integrity. At the same time, AI-powered solutions like anomaly detection and predictive analytics are equipping organizations with sustainable actions to thwart evolving threats. AI-driven cybersecurity reduced the average data breach cost from $4.45 million to $2.65 million in 2023, saving businesses an average of $1.8 million [3]. The study proposes concrete steps to strengthen cryptocurrency platforms against future threats by learning from past cyberattacks. It is crucial to work with governments, industry stakeholders, and technological innovators to collaboratively create digital environments that are secure & transparent. This research work around incorporating blockchain and AI to foster robust cryptocurrency system.
