To get from malicious site to installing malware is way, way harder.”Īpple also has added a couple of more obvious security and privacy features to OS X Lion, most notably FileVault 2, which now encrypts the entire disk using 128-bit AES. You need two to three bugs now where before you only needed one.

You can’t do the things you want to do, like install malware. “That process is sandboxed, so you can only read and write in certain places. “Webkit lives in a second process, so what will happen is if you get one bug and exploit that gets around ASLR, you end up in that second process,” Miller said. In the case of Safari, Apple has taken the step of putting Webkit in a separate process. In addition to the improved ASLR implementation, Lion also includes a sandbox that prevents applications from being able to make changes to a machine or take other actions they shouldn’t be able to take. Miller added that it’s also more difficult to find information disclosure bugs because they can’t be found with a fuzzer. You probably need two bugs now, one for code execution and one for information disclosure.” They made it much harder to exploit things. “In Lion it seems like everything is randomized and no code is loaded at a predictable address.

“OS X has always had this goofy ASLR implementation where the randomized the libraries but not anything else, and you could still play the games and reuse code as long as there was one thing that wasn’t randomized,” said Charlie Miller, principal research consultant at Accuvant, who does a lot of OS X security research.

The major browser vendors have been adding exploit mitigations and other protections in recent versions, but researchers have said that Safari, in particular, has not been up to the levels of security provided by IE, Firefox and Chrome.Īpple is attempting to fix that in Lion by finally putting in a full version of ASLR (address space layout randomization), which makes it harder for attackers to run code on a machine by placing objects in random spots in memory. As most Web users spend their online lives in the browser, it can be the most effective way to compromise a large number of people if you have an exploit for a bug in a popular browser. The most significant additions, experts say, is the full implementation of ASLR and a sandbox that make it much more difficult for attackers to exploit browser bugs via a drive-by download to install malware on a victim’s machine.ĭrive-by download attacks have been a popular and effective attack vector for a wide variety of phishing crews, cybercrime gangs and others for several years. Apple has released the newest version of its OS X operating system, dubbed Lion, and it includes a batch of new security protections that bring it up to the level of Windows and Internet Explorer.
