IPsec IKE daemon racoon is the iOS and is usually initiated when a VPN connection using IPsec setting. The details of the Corona-jailbreak allowed the hacker to disclose, as assumed may be that Apple after the release of the jailbreak soon the technical details out of date one of them (like other security researchers like Stefan Esser already had done).
