Security News > 2022 > April > Hackers steal $655K after picking MetaMask seed from iCloud backup
MetaMask has published a warning for their iOS users about the seeds of cryptocurrency wallets being stored in Apple's iCloud if app data backup is active.
MetaMask is a "Hot" cryptocurrency wallet used by over 21 million investors to store their wallet tokens and manage their digital assets.
Storing the wallet seed in iCloud practically means that if an owner has their Apple account compromised, their digital assets are also at risk.
If you have enabled iCloud backup for app data, this will include your password-encrypted MetaMask vault.
The hackers had already requested one final Apple account password reset and all they needed was the additional verification to access the victim's iCloud data where the MetaMask seed was backed up.
To keep your digital assets safe from such tricky attacks, make sure to exclude MetaMask from iCloud backups via Settings > Profile > iCloud > Manage Storage > Backups.
