Complete Microsoft EMET Bypass Developed
msm1267 writes "Researchers at Bromium Labs are expected to announce today they have developed an exploit that bypasses all of the mitigations in Microsoft's Enhanced Mitigation Experience Toolkit (EMET). Principal security researcher Jared DeMott is delivered a presentation at the Security BSides conference explaining how the company's researchers were able to bypass all of the memory protections offered within the free Windows toolkit. The work is significant given that Microsoft has been quick to urge customers to install and run EMET as a temporary mitigation against zero-day exploits targeting memory vulnerabilities in Windows or Internet Explorer. The exploit bypasses all of EMET's mitigations, unlike previous bypasses that were able to beat only certain aspects of the tool. Researchers took a real-world IE exploit and tweaked it until they had a complete bypass of EMET's ROP, heap spray, SEHOP, ASLR, and DEP mitigations."
EMET is just a bunch of industry-standard mitigations (e.g. the kind of thing you get on Linux with grsecurity) - and several of them poorly implemented at that. They're mitigations - they make exploits harder, not impossible.
If you rely on EMET for security, you're doing it wrong. Stuff like EMET is just a speed bump. It's good to have, it should be enabled by default, and we should stop treating it like some magic "security on" switch.
Is this a general method for bypassing EMET protections, or is it only applicable to one specific IE exploit?
... the arms race continues!
EMET is not a cure all, nor is it pushed as one. EMET is about standard best practises to mitigate many exploits (not all) and is still an excellent toolkit for what it offers, that doesn't mean you should rely on only it. And as usual the Slashdot summary comes across as far more negative than the actual article itself.
Windows, any version, is architecturally insecure. While it can be patched, you're never going to be able to completely eliminate the insecurities. Does Microsoft have a system integrity statement like this? I highly doubt it.
IBM’s commitment includes design and development practices intended to prevent unauthorized application programs, subsystems, and users from bypassing z/OS security – that is, to prevent them from gaining access, circumventing, disabling, altering, or obtaining control of key z/OS system processes and resources unless allowed by the installation. Specifically, z/OS “System Integrity” is defined as the inability of any program not authorized by a mechanism under the installation’s control to circumvent or disable store or fetch protection, access a resource protected by the z/OS Security Server (RACF®), or obtain control in an authorized state; that is, in supervisor state, with a protection key less than eight (8), or Authorized Program Facility (APF) authorized. In the event that an IBM System Integrity problem is reported, IBM will always take action to resolve it
These bit-twiddling desperadoes should be arrested at once!
Pre beta I can read the complete (in most cases) text without leaving the main page. With Beta I have to queue the (perhaps interesting) readings in tabs and then review them (in order to avoid the back-and-forth). Bad UI, bad UX, bad design. Takes so much longer that I may just quit reading this site.
Not a lot of credible hackers allowed to play with multimillion dollar hulks that dim the lights. I am pretty sure most systems are exploitable in theory no matter how much marketing people believe.

You mean how the cookie monster malware from the 1970s hit pdp and the 370 alike?
It would halt I/O unless you typed cookie on the teletype.

I hear the same stuff spewed by Linux fanboys who say rootkits are impossible. Yet get exploited. Where do you think the root in rootkit came from?
So basically if you don't use IE, then your EMET isn't vulnerable to this?
"...complete bypass of EMET's ROP, heap spray, SEHOP, ASLR, and DEP mitigations". All of these mitigations are pretty much state of the art and mandatory with most binaries and OS's compiled/built these days. It wasn't clear from the article if these were all generally bypassed or if something about EMET's implementation of them were at fault. Did they really get lucky with ASLR (1/256 chance), bypass DEP and heap spray detection, and exploit someone's IE session running as a std user?

.. This is true of EMET and other similar userland protections”
“The impact of this study shows that technologies that operate on the same plane of execution as potentially malicious code, offer little lasting protection,

That proves the opposite of what people think. It was for a very long time extremely effective. The auto scanning l33t hax0r tools out there only looked for port 22 for SSH. They didn't scan the system. If they didn't find it, they moved on. I saw massive differences in the number of failed logins for servers on 22 and servers not.
Now that has largely changed, but it worked real well for like a decade-ish. That is not worthless. No it wasn't the only layer of security, it wasn't an excuse to ignore everything, but it did a hell of a job reducing attack profile and costs -nothing-.
The problem is geeks seem to think if security isn't perfect, it is worthless, which is stupid because in the physical world there's no such thing, EVER, as perfect security and since all computers are in the end physical entities, the same actually applies to computer security. It is all layers, it is all protection against different levels of threats.
Turns out simple obscurity can be really useful at times. It doesn't make you safe by itself, but it can make a breakin that much harder, and thus less likely.
Cookie Monster was a prank program that required the user to install and run it with their own permissions. It didn't attempt to reproduce, spread or conceal itself.
Especially as there are no default ports that are open.
No active ports, no vulnerability to network attack.
So... EMET is SHEKER?
I blame the Vogons.
And how many kiddies scanning for SSH will just scan for 22, 222 2222 and 22222 and the like vs. say 19876 looking for SSH? If they want SSH access, they won't do a full port scan of all the IPs, they'll scan for a select set of known or probable "hidden" SSH ports on as many IPs as they can.
So yes, it's effective.
If someone is targeting YOU, they will scan all your ports and they will probably even try to speak SSH to you, if the reply on the port is from something that seems to be an Apache webserver.
Someone at Microsoft has a really creepy obsession with the word "Experience." Just stop already!
