Keplr Says Web3Auth Flaw Led to Private-Key Breach; Funds Moved to Recovery Wallets

Summary
Keplr says a Web3Auth infrastructure flaw exposed private keys for some Google- and Apple-login wallets. Web3Auth moved funds to recovery wallets; theft totals remain unclear, and the companies have not explained the flaw or restoration timeline.
Key points
- Keplr says a Web3Auth infrastructure flaw led to a private-key breach for some wallets created with Google or Apple sign-in; the companies have not explained how the flaw worked or when it was exploited.
- Web3Auth says it moved funds from at-risk wallets into recovery wallets across 11 Cosmos-family and eight Ethereum-style chains; an empty balance may therefore reflect a rescue transfer rather than theft.
- Keplr says wallets created with a recovery phrase or hardware wallet are unaffected, and it has paused Google and Apple sign-in while investigating.
- The wallet maker says staked and locked assets are taking longer to secure and is working on a way for users to check whether their accounts were affected. Web3Auth published a recovery-address list and warned that an unfamiliar destination is not necessarily attacker-controlled.
- Keplr co-founder Josh Lee initially estimated about 20% of social-login accounts were affected, with only a fraction apparently exploited. GoPlus estimated at least $1 million stolen but did not explain its calculation.
- Bitquery counted at least $6.01 million moving from more than 44,000 wallets to recovery wallets, then corrected its analysis to treat the transfers as rescues; it said it could not verify who controls those wallets.
