JOHANNESBURG, (CAJ News) – THE cryptocurrency sector continues to grapple with security challenges, with a fresh report revealing that $306.7 million was stolen through hacks in the third quarter of 2025.
The findings, published in the Finbold Q3 2025 Cryptocurrency Market Report and based on data from blockchain security firm SlowMist, underscore persistent vulnerabilities in the fast-growing industry.
While still alarming, the Q3 figure represents a significant decline compared to the $465 million lost in Q2 and the $1.77 billion wiped out in Q1, which was largely driven by the devastating $1.5 billion Bybit breach.
Despite the downward trend, the cumulative losses for 2025 have already surged to $2.55 billion, making it one of the most damaging years on record for the global crypto ecosystem.
Jordan Major, senior analyst at Finbold and co-author of the report, described the decline in quarterly losses as “encouraging” but warned that investors should not mistake short-term progress for long-term security.
“A single exploit still has the capacity to erase billions, and the Bybit breach earlier this year proves that point. Security is no longer an optional feature for exchanges and protocols; it’s the foundation of trust in the industry,” Major said.
Diana Paluteder, Finbold’s head of content and co-author, highlighted how 2025 has been defined by a concentration of risks.
“One major incident accounted for the vast majority of Q1 losses, while subsequent quarters have been shaped by smaller but persistent breaches. This shows that vulnerabilities remain across custody, DeFi contracts, and third-party integrations, even as defences improve,” she noted.
As the sector enters the final quarter of the year, analysts say the key challenge will be whether exchanges and decentralized finance (DeFi) platforms can sustain the downtrend in quarterly losses — or whether another large-scale exploit could once again shift the trajectory.
