CoW Swap domain hijacked via registrar social engineering; cloned site drains users through approvals
On 14 April 2026 attackers took control of the domain for swap.cow.fi and sent visitors to a cloned CoW Swap interface that asked for malicious token approvals. CoW DAO paused its backend and APIs and told users to revoke approvals made after 14:54 UTC; the protocol's smart contracts were not affected. Early estimates were about $500K drained; Halborn later put user losses at about $1.2M and said the registrar had been social-engineered.

Fake Ledger Live app on Apple's Mac App Store stole about $9.5M in seed-phrase thefts
A fake Ledger Live app for macOS, published on Apple's App Store under the name 'Leva Heal Limited', asked users for their recovery phrase and drained about $9.5M from roughly 50 victims between 8 and 11 April 2026. Apple removed the app and terminated the developer account; KuCoin froze accounts used to launder part of the funds. Ledger's desktop app is only distributed from Ledger's own website, and no Ledger software ever asks for your recovery phrase.

Report: Inferno/AngelFerno drainer still active in 2026, bought Purple Drainer in March
A Ransom-ISAC report published on 5 October 2026 says the Inferno drainer ecosystem, now branded AngelFerno after merging with Angel Drainer, was still running in summer 2026 with thousands of affiliates. It says AngelFerno announced it had bought Purple Drainer in March 2026, that its factory has deployed over 17,000 single-use drainer contracts, and that it targets 165 tokens on 11 EVM chains (with Solana, TRON, SUI and XRP variants). The report ties it to domain takeovers including CoW Protocol in April 2026 (about $1.2M lost) and notes a May 2026 key rotation that locked the operators out of their own command contract for about 23 days.
