This technique is a primary execution method for stagers associated with North Korean APTs, such as DEV#POPPER and OmniStealer, which are often hidden in legitimate-looking configuration files.

Detects the JavaScript XOR-based string reconstruction pattern used by the Coruna iOS exploit kit. This pattern maps an array of integers through String.fromCharCode with XOR to reconstruct code at runtime. Coruna contained 23 iOS exploits targeting iOS 13.0 through 17.2.1 and was used by UNC6353 (Russian espionage) and UNC6691 (Chinese financially motivated).
