In a comprehensive report released by De.FI, the cybersecurity firm behind the REKT database, shocking revelations have emerged about the rampant theft in the cryptocurrency realm throughout 2023. According to their findings, hackers managed to pilfer an astounding $2 billion from various crypto assets, showcasing the persistent threats faced by the decentralized finance (DeFi) ecosystem.
It is noteworthy that the $2 billion stolen in 2023 represents a decline from the previous year’s staggering record of approximately $3.8 billion in cryptocurrency theft. De.FI’s report, however, does not merely focus on the monetary aspect but underscores the broader implications of the data. It suggests that the reduced amount stolen in 2023 is indicative of both the existing vulnerabilities within the DeFi space and the concerted efforts being made to address them.
The report highlights several notable crypto heists that transpired during the year, with the hack against Euler Finance standing out as one of the largest, resulting in the loss of almost $200 million. Other major incidents included attacks on Multichain ($126 million), BonqDAO ($120 million), Poloniex ($114 million), and Atomic Wallet ($100 million), among numerous others. The dispersed nature of these incidents emphasizes the multifaceted challenges faced by the DeFi ecosystem.

De.FI’s report articulates, “This amount, though dispersed across various incidents, underscores the persistent vulnerabilities and challenges within the DeFi ecosystem. 2023 stood as a testament to both the ongoing vulnerabilities and the strides made in addressing them, even as interest in the space was relatively muted by the ongoing bear market in the first half of the year.”
Notably, this latest report from De.FI aligns with the findings of another reputable source in the cybersecurity domain, TRM Labs. In a parallel investigation, TRM Labs disclosed that as of mid-December 2023, the cumulative amount stolen in crypto had reached $1.7 billion. Despite the possibility of additional hacks in December, the year was anticipated to conclude with significantly lower totals compared to the alarming figures of 2022.
TRM Labs emphasizes the potential impact of the global focus on cybercrime in curbing illicit activities within the crypto space. Ari Redbord, the global head of policy and government affairs at TRM, remarked, “While we are always one Ronin-size hack away from a record-setting year, the global focus on cybercrime is likely to, at least in part, mitigate some of the activity which is critical for the overwhelmingly lawful ecosystem to grow.”
The top 10 hacks identified by TRM accounted for nearly 70% of all stolen funds in 2023. Noteworthy attacks on Euler Finance, Multichain, and Poloniex collectively netted criminals $100 million each. TRM further delves into the dynamics of these cybercrimes, highlighting that infrastructure attacks, such as private-key theft enabling access to a crypto project’s servers or software, played a substantial role, contributing to nearly 60% of the total stolen throughout the year.
In essence, the dual reports from De.FI and TRM Labs shed light on the intricate landscape of cryptocurrency theft in 2023. Despite the decline in the overall amount stolen compared to the previous year, the persistent vulnerabilities within the DeFi ecosystem demand continued vigilance and proactive measures to fortify the security infrastructure of the rapidly evolving crypto space. As the industry grapples with these challenges, the concerted efforts to address vulnerabilities and enhance cybersecurity will play a pivotal role in shaping the future resilience of decentralized financial systems.
