Act this weekWhat happenedAn attacker used a flaw at login provider Web3Auth to steal crypto from some Keplr wallets, and the provider moved other wallets' funds to recovery wallets.
Who is affectedPeople who set up a Keplr wallet with Google or Apple sign-in; wallets made with a recovery phrase or a hardware wallet are not affected.
What to do- 1Do not assume an empty balance means theft, because the money may have been moved to a recovery wallet.
- 2Check the recovery address list Web3Auth published to tell its transfers from suspicious ones.
- 3Do not send funds to an unfamiliar address, and do not assume one is linked to the attacker.
- 4Hold off on Google or Apple sign-in for Keplr, which is paused, and watch for the official tool to check your account.
Some people who set up a Keplr crypto wallet with their Google or Apple account have had money stolen. Others may open their wallet and find it empty even though no thief took the funds. The login provider says it moved that money to safety first.
What happened
Keplr uses a company called Web3Auth to run its Google and Apple sign-in. An attacker used a security flaw at Web3Auth to reach the wallets, both companies said late last week. Keplr called it a "private key breach" for some users. A private key is the secret code that approves payments, so whoever holds it can move the money.
Web3Auth says it then used the attacker's own route to empty other at-risk wallets before the attacker got to them. With help from Keplr, it moved that money into recovery wallets for safekeeping.
How much money is involved
Neither company has given a dollar figure for the theft. Keplr co-founder Josh Lee gave an early estimate: about 20% of Google and Apple login accounts were affected, and only a fraction of those appeared to have been exploited. GoPlus, a Web3 security company, said at least about $1 million was stolen, without explaining how it got that number.
Blockchain data firm Bitquery counted at least $6.01 million moving from more than 44,000 wallets into the recovery wallets. It first reported those moves as theft, then corrected itself to treat them as a rescue. It says it cannot check who controls the recovery wallets.
Who can relax
Wallets made with a recovery phrase (a backup list of 12 or 24 words) or a hardware wallet are not affected, Keplr said. Web3Auth also said its first look found no evidence that MetaMask users are affected. MetaMask's parent company, Consensys, bought Web3Auth in June 2025.
What to do
The steps are in the alert box above. The main point is to stay calm and rely on official updates. An empty balance is not proof of theft. Staked and locked assets are taking longer to secure, so those may not have moved yet. Web3Auth also warns that an unfamiliar address is not necessarily linked to the attacker.
What is still unknown
- How the flaw worked, when it was first used, and whether it is now closed.
- How and when rescued money will be returned to users.
- Whether other companies were hit. Web3Auth says some are exposed but has named only Keplr.
- When sign-in returns. Web3Auth's status page still showed its login service as down.
The takeawayIf your Keplr wallet uses Google or Apple sign-in and looks empty, it may have been rescued, so wait for official word before moving anything.
