Vulnerability: Samsung-branded Android Phones Allow Bypass of Lock Screen

A vulnerability was recently found in Samsung mobile Android devices, OS version 4.1.2, that would give an attacker (unauthenticated users) the ability to circumvent the screen lock, viewing the home screen. It can also give them rights to run apps, send arbitrary messages to contacts, rack up illegitimate phone services, etc. It could also lock out the original user of the device.

Terence Eden posted a video about the Galaxy Note II:

This isn’t the first time we’ve seen flaws on Samsung-branded Android smartphones. Before this, kernel trouble was the topic, where attackers can gain easy access to the Android kernel in some Samsung devices.

Adobe Flash Player Critically Affected Again! Two Bugs Resolved!

Adobe has published another update now, fixing three vulnerabilities. Two of these three vulnerabilities are currently being exploited in the wild.

Adobe has introduced the Flash Player sandbox a year ago protecting Firefox users from vulnerabilities in Flash Player. This sandbox is being actively targeted for attacks.

“Adobe is aware of reports that CVE-2013-0643 and CVE 2013-0648 are being exploited in the wild in targeted attacks designed to trick the user into clicking a link which directs to a website serving malicious Flash (SWF) content,” the company wrote in a security bulletin.

Adobe classifies the update at priority rating of 1 for Windows and Mac (which means super-critical: PATCH NOW!), and 3 for Linux (not as critical for Linux).

Google automatically patches for Chrome Browser. Microsoft automatically patches for Internet Explorer 10 for Windows 8 (note for Internet Explorer 10 for Windows 7, you have to patch).

The following issues are resolved:

  • Permissions issue with the Flash Player Firefox sandbox (CVE-2013-0643)
  • ExternalInterface ActionScript feature (CVE-2013-0648)
  • Buffer overflow in Flash Player broker service (CVE-2013-0504).

Microsoft Humbled: Hit by Cyberattack as well

We reported on all the recent cyberattacks lately, but didn’t catch this, so here’s an addendum to yesterday’s story:

As reported by Facebook and Apple, Microsoft can confirm that we also recently experienced a similar security intrusion.

Consistent with our security response practices, we chose not to make a statement during the initial information gathering process. During our investigation, we found a small number of computers, including some in our Mac business unit, that were infected by malicious software using techniques similar to those documented by other organizations. We have no evidence of customer data being affected and our investigation is ongoing.

Recent Hacks: NBC.com, Twitter, and Zendesk – Warnings: Tumblr, Pinterest

After dealing with multiple attacks on several sites, including Apple, Facebook, and Twitter – this being Java exploits. Now, it’s time to deal with more hacks, including NBC.com (which has been serving up malware for a day now) and Twitter. As in recent reports now, Tumblr and Pinterest have been forewarned.

The latest high profile organization that was recently hacked is the National Broadcast Company (NBC), more specifically on their website. The idea from the hackers is to use the website to infect visitors, using exploits and other JavaScript injections.

NBC.com’s hacked pages were modified to include additional HTML component called IFRAME, which is inline frame. This allows at least a 1px x 1px frame to be included independently in the webpage, which may contain malicious code. In HTML code, frames can be made to host web content. But, in the hands of the evildoers, aka cybercriminals, it is used as an effort to launch malware campaigns.

Malicious JavaScript was added to the mix, and also used the exploit kit called RedKit. It delivers one of two exploit files to try to take control of your browser.

I recognized something was wrong with NBC.com, which may have already been hacked a few weeks ago, and I posted the information on my Twitter account that a downloaded file was sent to my browser asking me to save or open it. This was on a sister site/blog, RedTape. I asked people to replicate it. The Twitter status can be found here.

What type of malware was delivered? Citadel or ZeroAccess, which are both crimeware families and botnets. They are usually part of several exploit kits.

This drive-by download situation is no good, as the pages were taken offline. Therefore, that dropped the traffic of those specific areas of the site. It is sure that this situation is a matter of cybercrime aimed at a financial side of things, not defacement or pranks.

Was it a big deal that it was NBC? No. In fact, it is sure the hackers were aimed at using a high-profile site, and apparently NBC.com was the easiest or quickest to access. Hackers rely on time and many other factors to make their approach(es).

Zendesk hacks and other various warnings

Zendesk is all about customer support…therefore no one really knows, except for those in the business of customer support. Big names use this service, which include Tumblr, Twitter, and Pinterest, among others. Hackers broke into the Zendesk systems, accessing email addresses of those big name customers, namely Twitter, Tumblr, and Pinterest.

How “pinteresting” that another hack has been born, which is related to a social network. Zendesk detailed the hack:

We’ve become aware that a hacker accessed our system this week. As soon as we learned of the attack, we patched the vulnerability and closed the access that the hacker had. Our ongoing investigation indicates that the hacker had access to the support information that three of our customers store on our system. We believe that the hacker downloaded email addresses of users who contacted those three customers for support, as well as support email subject lines. We notified our affected customers immediately and are working with them to assist in their response.

The companies involved made a point to tell its customers that they haven’t been hacked, but private information was stolen. Luckily, no password thievery was involved.

Obviously, an incident like this, just like the NBC.com incident, needs to be taken very seriously. Something must be done to stop the continuous hacks.

Twitter hacks additionally are nothing new. Many times, hackers used a backdoor, such as the tools the support team uses, to infiltrate the information of Twitter users. It’s not a huge gain, more possibly a waste of time.

Version 19 Update for Firefox – Patched HTTPS Phishing Issues, PDF Viewer Added

Firefox 19 now has a PDF viewer (Yay, bells and whistles)! Time to kick Adobe Reader, you know, because of all the exploits.

According to TheNextweb.com, Firefox 19 “includes PDF.js, a JavaScript library intended to convert PDF files into HTML5, which was started by Andreas Gal and Chris Jones as a research project that eventually picked up steam within Mozilla Labs.

Technically, the tool has been in Firefox for many versions, but you had to manually enable it. The whole point of the built-in PDF viewer is to avoid having to use plugins with proprietary closed source code “that could potentially expose users to security vulnerabilities.””

The new PDF viewer doesn’t even require a secondary plugin or anything! It has its own ability to draw images and text.

A little more explained:

“Firefox for Windows, Mac and Linux introduces a built-in browser PDF viewer that allows you to read PDFs directly within the browser, making reading PDFs easier because you don’t have to download the content or read it in a plugin like Reader. For example, you can use the PDF viewer to check out a menu from your favorite restaurant, view and print concert tickets or read reports without having to interrupt your browsing experience with extra clicks or downloads,” Mozilla said.

In addition to that exciting news, Firefox 19 also fixes an HTTPS phishing flaw, which was reported by Michal Zalewski, Google security researcher. It details an issue with a proxy’s 407 response, where if a user canceled the proxy’s authentication prompt, the browser continues to display the address bar. This can be spoofed by attackers, by telling them to enter credentials. Read more in the Mozilla advisory about this.

Also, several use-after-free vulnerabilities were patched, and memory corruption vulnerabilities.

In Firefox, if you’re not automatically prompted to update, then do so as soon as possible by clicking the Firefox tab at the top left corner of the browser, hovering over Help >, click on About Firefox. You may also have to click Check for updates in the window that pops up. You should be patched.

Also, check out the posts today about Java and Adobe Reader being patched as well. It’ll be time to update everything at once.

New Java Update Available by Oracle, Sped Up Patching Process

At least 5 security issues were patched in yesterday’s release of Java. This was all problematic generated by a string of problems including hacks on Facebook computers, among Apple and Twitter. Recently, at least 40 companies were targeted in malware attacks leading to an Eastern European gang of hackers trying to steal private corporate information, according to Bloomberg News.

The new version, now available on Java.com will bring the current version to Java SE 7 Update 15 and Java SE 6 Update 41. It is recommended to unplug your browser from Java, at least the main one, and only use Java Runtime Environment (JRE) in a lesser-used browser. Whenever you need to use a site that required Java, use it on your rare browser, so that you don’t get tripped up by ads or other exploit sites that try to access Java on your main browser.

Additionally, make sure to occasionally clear the Java cache, which will help prevent old temporary files for Java from loading. It’ll make the Java experience a bit better. This may also help remediate issues, if a Java application doesn’t run.

Oracle has announced on its website that it will “start auto-updating all Windows 32-bit users from JRE 6 to JRE 7 with the update release of Java, Java SE 7 Update 15 (Java SE 7u15), due in February 2013.”

Oracle will speed up its patching cycle for Java. “Oracle’s intent is to continue to accelerate the release of Java fixes, particularly to help address the security worthiness of the Java Runtime Environment (JRE) in desktop browsers,” Eric Maurice, director of Oracle’s software assurance, said.

Adobe Releases Emergency Patch for Adobe Reader

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).
