Pwn2Own (2013) Contest a Blast – FULL Results

pwn2own

CanSecWest is a conference, and 2013’s conference once again involved the Pwn2Own contest for hackers, an elite (1337) competition. The concept remained simple and will always that if you pwn a fully-patched browser running on a fully-patched laptop, you get to keep the laptop.

However, different rules applied this year. It involved successfully demonstrating the exploit, providing the sponsor (HP) the fully functioning exploit, and all details involved with the vulnerability used in the attack. If there were many vulnerabilities, multiple reports are needed, etc.

The work couldn’t be sold to anyone else, and proof of concept would belong to HP once sold. Basically, HP buys the winning exploits for own use. Their idea of reward money was the following:

  • Google Chrome on Windows 7 = $100,000
  • IE10 on Windows 8 = $100,000 or IE9 on Windows 7 = $75,000.
  • Mozilla Firefox on Windows 7 = $60,000
  • Apple Safari on Mac OS X Mountain Lion = $65,000
  • Adobe Reader XI and Flash Player = $70,000
  • Oracle Java = $20,000

It was assuredly a blast at the competition, no doubt about it.

DAY ONE: Java, Chrome, IE10, and Firefox PWNED!!!

(Where’s Safari, right? It survived!)

The idea behind each attack is the ability to browse to an untrusted website where you’re able to inject and run arbitrary code outside of the browsing environment.

Of course, one of the rules is: “A successful attack … must require little or no user interaction and must demonstrate code execution… If a sandbox is present, a full sandbox escape is required to win.”

ie-ff-chrIn addition to Chrome, Firefox, and IE10 being pwned, Java was pwned three times on the first day. Once by James Forshaw, Joshua Drake, and VUPEN Security. VUPEN Security also led a lot of the pack of issues by successfully exploiting IE10 and Firefox as well.

The only other exploit was by Nils & Jon, where both successfully exploited Chrome.

The day after the first day of Pwn2Own, Mozilla and Google patched the exploits that were pushed out. Amazingly fast, Firefox went on to version 19.0.2 (which you should’ve been updated automatically), and Chrome went on to version 25.0.1364.160 (effectively patching 10 vulnerabilities).

“We received the technical details on Wednesday evening and within less than 24 hours diagnosed the issue, built a patch, validated the fix and the resulting builds, and deployed the patch to users,” said Michael Coates, Mozilla’s director of security assurance, in a Thursday blog.

Microsoft has decided to wait until next week’s Patch Tuesday run of updates to push out the fix for the Internet Explorer exploit on IE10.

DAY TWO: Adobe Reader and Flash Player PWNED!!! Java PWNED AGAIN!!!

The last day of Pwn2Own 2013 went with a BANG!fl-ar-ja

Flash Player…exploited by VUPEN Security (any surprise?). Adobe Reader PWNED by George Hotz. Java once again was exploited, this time proxied by Ben Murphy.

Who’re the overall prize winners?

  • James Forshaw, Ben Murphy, and Joshua Drake for Java – each $20,000
  • VUPEN Security for IE10 + Firefox + Java + Flash – $250,000
  • Nils & Jon for Google Chrome – $100,000
  • George Hotz for Adobe Reader – $70,000

Of course, George Hotz is best known for jailbreaking the iPhone and PlayStation 3. He’s still in progress with a lawsuit with Sony over the issue for PS3.

It’s amazing to see that Java was PWNED 4 times in just two days, but is it any surprise based on the number of vulnerabilities Oracle has dealt with for Java?

Now in its eighth year, Pwn2Own contest had $480,000 in payouts, a record year. Amazing!

Adobe Releases Emergency Patch for Adobe Reader

vulnerability

Adobe has released its emergency patch after a string of events in the past nearly ten days on dealing with a zero-day vulnerability. This was originally reported by FireEye in a blog post.

The FireEye blog stated the following:
“Upon successful exploitation, it will drop two DLLs. The first DLL shows a fake error message and opens a decoy PDF document, which is usually common in targeted attacks. The second DLL in turn drops the callback component, which talks to a remote domain.”

After that was published, the FireEye researchers sent the bug report & sample to Adobe. Soon after, Adobe released a notification that there is a problem.

Eventually, Adobe detailed this past weekend that a patch would be available next week…well it’s here.

Adobe released its patch yesterday, in efforts to remediate the situation.

According to Adobe, the following versions are now available:

  •  Users of Adobe Reader XI (11.0.01 and earlier) for Windows and Macintosh should update to Adobe Reader XI (11.0.02).
  •  For users of Adobe Reader X (10.1.5 and earlier) for Windows and Macintosh, who cannot update to Adobe Reader XI (11.0.02), Adobe has made available the update Adobe Reader X (10.1.6).
  •  For users of Adobe Reader 9.5.3 and earlier 9.x versions for Windows and Macintosh, who cannot update to Adobe Reader XI (11.0.02), Adobe has made available the update Adobe Reader 9.5.4.
  •  Users of Adobe Reader 9.5.3 and earlier 9.x versions for Linux should update to Adobe Reader 9.5.4.
  •  Users of Adobe Acrobat XI (11.0.01 and earlier) for Windows and Macintosh should update to Adobe Acrobat XI (11.0.02).
  •  Users of Adobe Acrobat X (10.1.5 and earlier) for Windows and Macintosh should update to Adobe Acrobat X (10.1.6).
  •  Users of Adobe Acrobat 9.5.3 and earlier 9.x versions for Windows and Macintosh should update to Adobe Acrobat 9.5.4.

 

Get Alternative Software for Adobe Reader

Are the latest band of exploits too challenging for you? Want something different? Tired of updating Adobe Reader once to twice a week?

Here is a short list of PDF viewers, the best alternatives for Adobe Reader.

  • Sumatra PDF

    This program is extremely lightweight, easy on resources, and fun to use for its ability to get the job done. Open a PDF.

  • Foxit Reader

    Free, lightweight – Foxit Reader is a great alternative for Adobe Reader. Although not as thin on the resources or fast like Sumatra, Foxit sure has a lot to offer. How about text converter, highlighting, or even integration with DocuSign services? Awesome!

  • Nitro PDF Reader

    This is similar to Sumatra. Nitro has some other features to offer, including free editing tools. This does have a bit of a pokey interface, like Adobe Reader can be sometimes, but still looks slick!

There you have it! Good luck!

Windows 8 Security Features Explained (mini-whitepaper)

Windows 8 is apparently more secure than Windows 7. Perhaps this is true, and it is best to learn what security features there are for the new operating system. Some of these security features are verified to help out very well in the security of Windows 8, and some may not be in time, or lastly some may not work at all.

One of the most discussed security features is Secure Boot. Now, Secure Boot is a Unified Extensible Firmware Interface (UEFI) specified in the boot process to check cryptographic signatures of kernel-mode drivers, making sure they aren’t modified or corrupted. In other words, the boot process is now made to check if the operating system has been corrupted by malware or some other issue.

This is all part of a hardware restriction process called Hardware DRM. All non-ARM devices have the option to turn Secure Boot off, however ARM devices must keep it on. Experts state that it will be resistant to rootkits, since the MBR and BIOS cannot be accessed, unless if someone working on the computer penetrates it.

Next, Windows 8 features better built in antivirus software, with a much better improved Windows Defender. The software in Windows 8 is combined with the optional tool Microsoft Security Essentials. Now, with Windows Defender super-powered with MSE, it has much more anti-malware features.

With better anti-malware features, Internet Explorer is now made with better features as well. It has the ability to prevent zero-day exploits much greater than previous versions of Internet Explorer. With the challenges of exploiting Windows 7, there was the issue risen up again for Java and Flash Player, so hackers can gain control over the operating system. Those browser plugins are now easier to exploit than the Internet Explorer’s code.

A new application sandboxing environment called AppContainer provides the ability to run all apps in a controlled environment, where it controls how apps work. This prevents apps from disrupting the operating system. Of course, this is just supplemented by Internet Explorer’s SmartScreen filter, which prevents the download/install of known malicious software. However, Windows 8 now has SmartScreen available for any app, allowing even more prevention. Of course, this means Microsoft employees are going to increase in numbers, if they really want to keep up. Now that hackers know their new challenges, they will be relentless.

The questions are still played on whether Windows 8 will be a repeat of Vista or not. The reality of the situation, is if Windows 8 has big popularity, then the security issues will also light up big time. However, many will stick to Windows 7, so the security issues for Windows users are not close to be over. Feel free to take a look at related articles below for Symantec’s opinions, which aren’t too well on the new OS.

Java Flaws Becoming Serious Issue

vulnerability

Java exploitation has been a problem for years. Many of the issues encountered with Java exploitation are usually because versions are out-of-date.

Web-exploit-toolkits are used by attackers to attempt exploits at common vulnerable plugins, including Java, Adobe Flash Player, and Adobe Reader.

“As the Advanced Malware Analysts administrator/group owner, I see a lot of issues with people not updating Java, Flash Player, and Reader. These attack vectors were used 5 or so years ago, up until today. Still a complete problem. Problem is, people do not use great tools like Secunia PSI or the auto-update feature in each of the plugins’ control panels,” says Jay Pfoutz – administrator and group owner of the Advanced Malware Analysts. The Advanced Malware Analysts are a group of malware analysts whom volunteer on tech support forums across the web to assist in malware removal for free.

Exploitation frequently happens when people fail to update their plugins in a timely manner. Java plugin problems lately have increased because attackers are now targeting Java a lot more.

Here is how to check for the latest updates for Java (should be done weekly):

  • If using Mozilla Firefox, Plugin Check is the easiest way.
  • Click Start, navigate to Control Panel. Look for Java in the list, and double-click on that. Click the “Update” tab, and then click the “Check for Updates Automatically” check box if you want Java to search for updates automatically. Select how you want Java to notify you about available updates. Or you can hit the Update Now button. More info here
  • Verify Java Version Online

By doing this, you are ensuring prevention from malware exploitation. However, it won’t be enough. Please download and install the following also:
