Load of farce with no clue what you're talking about. First off, Pangu's an UNTETHERED jailbreak. If you bothered to Google the term at all or if you had any clue what you're talking about, you'd know. Secondly, every jailbreak utility as well as plenty of Android rooting utilities are executables. PanGu already stated that they did not ZIP the Cydia archives hence the 80MB utility. Thirdly, any and every rooting/jailbreaking utility is a risk, so is rooting/jailbreaking because you're exploiting the device/mobile OS, so I don't get why you're arguing over security issues and all, because once your device is rooted/jailbroken, your security is ripped wide open, that's a known fact since the beginning of iOS jailbreaking and Android rooting.
Get your facts straight before posting an article, because this "article" seems to be ripped off of an 8 year old or probably was written by an 8 year old. This article is not different from scam sites like evad3rs.net, Team7Jailbreak.com and evasion7.com, just stirring up attention. Pathetic....
