Crypto losses have reached an unprecedented $2.1 billion in the first half of 2025, primarily driven by sophisticated infrastructure exploits targeting private keys and front-end vulnerabilities. TRM Labs reports that these attacks, often amplified by social engineering, are responsible for over 80% of the stolen funds across 75 incidents, highlighting a significant escalation in threats to digital assets.
Record-Breaking Losses in H1 2025
The first half of 2025 has seen crypto losses surpass the previous record set in 2022 by approximately 10%, nearly equaling the total losses for all of 2024. This alarming trend underscores a growing concentration of threats within the digital asset landscape.
Infrastructure Exploits: The Primary Culprit
Infrastructure attacks, which target the technical backbone of crypto systems, have emerged as the dominant method for illicit gains. These exploits, including the hijacking of crypto wallet seed phrases and the compromise of user-facing protocols, on average, yield ten times more than other attack types.

Key Takeaways:
-
Over 80% of crypto stolen in H1 2025 resulted from infrastructure exploits.
-
These attacks exploit foundational weaknesses and are often amplified by social engineering.
-
Examples include private seed phrase hijacking and front-end compromises.
-
State-Sponsored Actors Fueling the Surge
State-sponsored groups are increasingly implicated in these large-scale thefts. A notable incident includes North Korea's $1.5 billion hack of Dubai-based crypto exchange Bybit in February, which alone accounted for nearly 70% of the total losses in H1 2025. This single event significantly inflated the average hack size to nearly $30 million, double that of H1 2024.

Notable Incidents:
-
North Korea's $1.5 billion Bybit hack.
-
Pro-Israel hacker group Gonjeshke Darande's $100 million exploit of Iran's Nobitex.
-
Protocol Exploits and Other Attack Vectors
While infrastructure attacks dominate, protocol exploits, such as flash loan and re-entrancy attacks, also contributed significantly, accounting for 12% of the losses. These attacks target vulnerabilities in smart contracts or core blockchain logic to extract funds or disrupt system behavior.
A Call for Collective Security
TRM Labs emphasizes the urgent need for a multifaceted approach to combat these escalating threats. Recommendations include reinforcing fundamental security measures and fostering collaboration among global law enforcement, financial intelligence units, and blockchain intelligence firms.
-
Recommended Security Measures:
-
Multi-factor authentication.
-
Cold storage solutions.
-
Frequent security audits.
-
Prioritizing insider threat detection.
-
Advanced social engineering countermeasures.
-
TRM Labs concludes that the record thefts in H1 2025 serve as a stark call to action for a collective, sustained, and strategically aligned security posture, prepared not only for criminal activity but also for covert acts of statecraft.
