Cyber threat intelligence challenges: Leveraging blockchain intelligence with possible solution

Technology of cyber threat intelligence (CTI) is a proof-based defense framework that proactively reacts by monitoring and exchanging security-related information of advanced cyber threats among different industries. The efficiency of CTI systems may be considerably impeded by developing and disseminating inappropriate protection policies. Although global attention is on the health and the economic challenges raised by COVID-19, this epidemic is certainly being exploited by cybercriminals across the globe. The attackers use the COVID-19 to embellish brands in a way that causes workers and consumers to make mistakes, spam, and ransomware attacks are at peak. In this article, we discuss many current and new cyber threat challenges and examine the latest case analysis. Finally, we have proposed a new system on Collaborative Cyber Threat Information Exchange (CCTI) underlining a wider group's capacity to help to recognize faults via an artificial intelligence computing essence focused on blockchain.
