The primary danger of using modified IPAs is the compromise of device security. Official apps on the App Store undergo rigorous sandboxing and review.

Since these apps are not automatically updated, they often remain vulnerable to exploits that official patches would otherwise fix. The Legality and Impact on the Industry
