What is an intent redirection vulnerability in Android?

It's when a malicious app hijacks communication signals (intents) between apps, sneaking past security to grab private data—like in this EngageSDK case.

Which crypto wallets used the vulnerable EngageSDK?

Over 30 million installs across third-party wallets; specifics not named, but all pulled from Play Store. Update to SDK 5.2.1 or later.

Keep apps updated, enable Play Protect, avoid sideloading, and stick to audited wallets from big players.
