Noteably, when attempting to run the evasi0n. This is very true, as it needs to download the WWDC app as part of the exploit.

Examining the symbol table we do see that there are references to "send", "recv", and other C-socket calls, however they appear to be used exclusively for the unix socket to communicate directly with the iOS device. Examining the list of libraries linked to the binary gives some insight to how it was checking for a network connection. This stands out due to the compatibility version listed being higher than the version OS X Checking the symbol table again evidence of how libcurl can be seen.

Digging into the code in the binary, it appears as these commands are used to do a check against the address http: This appears to be a binary file that dictates the internal operation of the evasi0n7. Specifically it is known to be able to enable and disable ability to install the TaiG payloads. The major controversy surrounding this release was that the evasi0n7. If this check was successful, it would install the TaiG app store by default instead of Cydia, and present Cydia as a secondary option.

See followups at drspringfield. By placing data in a known location past the array it's possible to hijack the tty structure and special read and write data from ioctl calls, and control function pointers to control execution. The exploit is actually quite simple to trigger. I discovered this with a simple fuzzing script to test out every single device node. Here's a small sample script that should crash the latest maverick update. It seems that only 16 spaces are allocated for these terminals and if you make a device node with major 16 and minor larger that 16 you start getting out of bounds of the array.

The maximum size of device nodes are about 0x giving to the ability to offset your pointer into a crafted structure very large. The only hard part is finding which zones are ahead of your array you can index into. The crash happens in…. The problem is they lack the check to see if the minor number is higher than the number of spots allocated. The problem comes down to this, I'll try to comment code as I go through it It just automatically returns this array indexed with a user controllable value. Crash but true, let's look more into this structure we can control if we create a large minor number.

The first pointer in this structure is a pointer to a tty structure.

This structure is easily readable and writable using using user land APIS. It also includes some function pointers in there which can be triggered to gain. You can imagine all the power you could do if you can control all these structures carefully.

That will be the difficulty when trying to exploit. You need to find a kernel zone past this array and allocate your data into it in a way you always know the offset. We must know it's an address, but we also leak a bit near the address if it is an address.

We should also be able to retrieve the value of all these state variables it sets from variable bits wherever the pointer is at to see if it's the correct pointer or not. Examine the read, write, and select apis for these terminals to learn all you can do. Also since it uses the tty zone for allocating this devices, it might be a very predictable zone if we can control all the pseudo terminals.

Also checking out return values based on flags in structs can be a good way to feel around in memory. New in iOS 7. Also the user filesystem containing all the data is mounted to disallow super user files, and device nodes. May 7, If the Avast web site were hacked to contain a malicious installer rather than the real installer, what makes you believe that an MD5 posted on the same web site would be immune to change?

You're looking for security in all the wrong places. Jul 22, 7: Jul 22, 8: Avast actually has quite good detection rates when it comes to detecting Mac malware.

I can say that definitively because I tested that in January:. To call it, and all other free anti-virus software, a scam is not fair, and is not based on fact. If you had simply said that anti-virus software on a Mac is unnecessary for most people, given appropriate precautions, I'd have had no argument. To call it a scam based on an opinion, however, is irresponsible. Jul 22, For the most part it's unnecessary, until you have some relevant malware on your system that an AV utility may have been able to catch. The arguments for or against being proactive in this manner on the Mac is an endless loop of ideas and opinions, but if you are concerned and dont feel you have the computing "street smarts" that are often described by savvy users as being the only way to go, then a free and lightweight AV utility will not hurt your system at least not more than most other programs , and potentially help you avoid suspicious files you might encounter.

Sophos home edition is a free, well-performing, reputable, and lightweight AV package that I recommend for anyone who would feel more comfortable having an AV solution on their system. I have installed it on most of my systems and it's never given me a problem.

Notebooks Speciality level out of ten: This comment applies to malicious software "malware" that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer.

That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help. All versions of OS X since This feature is transparent to the user, but internally Apple calls it "XProtect. It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets see below.

It only applies to software downloaded from the network. Software installed from a CD or other media is not checked. Starting with OS X By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple.

Software certified in this way hasn't actually been tested by Apple unless it comes from the Mac App Store , but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe. It can easily be disabled or overridden by the user.

A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to evade Apple's controls. For more information about Gatekeeper, see this Apple Support article. Some reputable websites did legitimately warn users who were infected with the "DNSChanger" malware.
