Abstract |
In the face of escalating cyber threats such as ransomware attacks, internet
scams, and email extortions on a global scale, accurately estimating the overall
damage remains a daunting challenge. The diversity in the forms and currencies
involved in these cybercrimes complicates efforts to comprehend the full extent of
the inflicted harm. Existing reporting mechanisms primarily shed light on incidents
disclosed by victims, leaving a substantial number of attacks and pilfered funds
unaccounted for.
The cybersecurity landscape hosts numerous Computer Security Incident Response Teams (CSIRTs) and Blockchain Threat Intelligence Platforms, yet their
isolated operations contribute to a fragmented data landscape. This fragmentation hinders a holistic understanding of potential threats, exacerbated by major
platforms like Chainalysis withholding data from public access. The resultant lack
of integration and limited accessibility to data from key players pose significant
barriers to accurately assessing the scope and severity of security incidents.
Remarkably, a notable proportion of these cybercrimes unfolds within blockchain
environments. Paradoxically, criminals’ attempts to conceal identities often unveil
critical information. By tracing attackers’ wallet addresses, a comprehensive time-
line of the crime emerges, from inception to the dispersal of ill-gotten funds. This
methodology facilitates quantifying the scale of the crime in cryptocurrencies, such
as Bitcoin, with the potential for conversion to conventional currencies. Crucially,
it enables the comprehensive tracking of all funds amassed by attackers, regardless
of official reporting.
Motivated by these challenges and opportunities, we have developed a system
that systematically collects, processes, and visualizes public datasets. This approach enhances the understanding and assessment of the impact of cybercrimes,
particularly within blockchain realms, addressing the current limitations in estimating the overall damage caused by these sophisticated threats.
