A new warning warns of dangerous apps on smartphones, particularly for crypto wallet users, that look like real apps but are fake. These apps steal wallet info by copying logos and names of trusted apps and asking for a mnemonic phrase. Over 20 fake apps have been found, targeting 9 popular wallets. Developers who created these apps have had their accounts hacked and misused. Many have been removed from the Play Store, and Google has responded by removing all reported apps.
