An alternative rootkit ? Privilege level 16 used by the Lawful Intercept [12] feature could be abused to do some of this too. Or the other way around: use a "patched" IOS to keep an eye on Law Enforcement's

The combination of rootkits and specially privileged Lawful Intercept functions is a very dangerous one. This was precisely what was exploited in the now-legendary and still unsolved Vodafone Greece hack.
Perhaps the above should be simplified. Running a hacked/modded IOS version is a dangerous prospect. This seems like such a non-event because what is the exploit path to load the image? There needs to be a primary exploit to load the malware image. *yawn* - Jared
