Crypto Hacks Plunge 85% in October 2025 to Lowest Losses of Year

TLDR

• Crypto hacks fell 85.7% in October 2025, with total losses of $18.18 million across 15 incidents compared to September’s $127 million
• Garden Finance suffered the largest breach at $11 million after a solver compromise on October 30
• Typus Finance lost $3.4 million through an oracle manipulation attack, while Abracadabra lost $1.8 million in its third exploit
• October 10 saw over $20 billion erased in leveraged trades during a market crash, marking the largest liquidation event in crypto history
• Security experts warn the decline may be temporary as North Korea-backed hackers develop new tactics to embed malicious code into blockchain networks

October 2025 marked the safest month for cryptocurrency security all year. Total losses from hacks and exploits reached just $18.18 million across 15 separate incidents.

Blockchain security firm PeckShield tracked the monthly figures. The data shows an 85.7% drop from September’s $127.06 million in stolen funds.

Three major breaches accounted for most of October’s losses. Garden Finance, Typus Finance, and Abracadabra collectively lost $16.2 million.

Garden Finance took the biggest hit. The Bitcoin peer-to-peer protocol disclosed a breach on October 30 that drained more than $10 million.

The exploit targeted one of Garden Finance’s solvers. Only the solver’s inventory was affected in the attack.

Without the Garden Finance incident, October would have seen just $7.18 million in losses. That figure would represent the lowest monthly total since early 2023.

Major October Breaches

Typus Finance experienced the second-largest exploit. The yield platform built on Sui lost roughly $3.4 million on October 15.

Hackers used an oracle manipulation attack. The breach exploited a flaw in one of the project’s TLP contracts.

The attack caused immediate market damage. Typus Finance’s native token dropped approximately 35% following the disclosure.

Abracadabra faced its third exploit since launching. The DeFi lending platform lost about $1.8 million in MIM stablecoin.

Hackers bypassed solvency checks through a smart contract vulnerability. The breach highlighted ongoing security challenges for the protocol.

PeckShield tracked suspicious wallet activity throughout the month. Over 8,600 ETH moved through wallets linked to cybercriminals.

October 10 became one of the darkest days in crypto market history. A sudden crash erased over $20 billion in leveraged trades within hours.

The liquidation event marked the largest ever recorded. The crash overshadowed the month’s security breaches in terms of total value lost.

New Threats Emerge

Security experts caution against viewing October’s decline as a lasting trend. State-sponsored groups continue developing new attack methods.

North Korea-linked hackers are testing fresh tactics. These groups are working to embed malicious code directly into blockchain networks.

This approach could bypass traditional security layers. The tactic creates new risks for decentralized systems.

Cybersecurity professionals warn that threat actors evolve constantly. While DeFi protocols strengthen defenses, attackers adapt at the same pace.

The market crash may have temporarily slowed hacker activity. Reduced on-chain transactions during volatile periods can limit exploit opportunities.
