Kony Packer should be detected as

/lib/arm64-v8a/libkonyjsvm.so
/assets/application.properties

exist but

/assets/js/startup.js

doesn't exist which break existing rule

rule kony : packer
{
  meta:
    description = "Kony"
    url = "http://www.kony.com/"

  strings:
    $lib = "libkonyjsvm.so"
    $decrypt_keys = "assets/application.properties"
    $encrypted_js = "assets/js/startup.js"

  condition:
    is_apk and $lib and $decrypt_keys and $encrypted_js
}

@apkunpacker do you think this rule would fix it? is_apk and $lib and ($decrypt_keys or $encrypted_js)?
