Crypto hacks drained $2.68 billion through September, while October has already added more than $98 million. An estimated $86 million or more was taken from tampered Ledger devices, and a separate exploit at 79th Vault drained $12.5 million.
Why it matters
The latest losses show how security failures can span both user hardware and DeFi infrastructure. The Ledger incident accounts for most of October's reported damage, while the 79th Vault exploit adds a separate protocol-level risk.
Market impact
The incidents increase scrutiny on device integrity, wallet security and DeFi vault controls. With October losses already above $98 million, further exploits would push the year's stolen-funds tally higher and keep security risk central to crypto market analysis.
