Adobe Flash Bug | Spy On The Webcams of Your Website Visitors

A slight variation of a previously designed clickjacking attack that used a Adobe Flash vulnerability has once again made it possible for website administrators to surreptitiously spy on their visitors by turning on the user's computer webcam and microphone.
It works in all versions of Adobe Flash that the researcher have tested . He’ve confirmed that it works in the Firefox and Safari for Mac browsers. Use one of those if you check out the live demo. There’s a weird CSS opacity bug in most other browsers (Chrome for Mac and most browsers on Windows/Linux).

Clickjacking + Adobe Flash = Sad Times!

This attack works by using a neat variation of the normal clickjacking technique that spammers and other bad people are using in the wild right now. For the uninitiated:

Combine clickjacking with the Adobe Flash Player Setting Manager pageand you have a recipe for some sad times.

How the attack works ?

Instead of iframing the whole settings page (which contains the framebusting code), Just  iframe the settings SWF file. This  bypasses the framebusting JavaScript code, since we don’t load the whole page — just the remote .SWF file. I was really surprised to find out that this actually works!

 A bunch of clickjacking attacks in the wild,  never any attacks where the attacker iframes a SWF file from a remote domain to clickjack it — let alone a .SWF file as important as one that controls access to your webcam and mic!

The problem here is the Flash Player Setting Manager, this inheritance from Macromedia might be the Flash Player security Achilles heel.

Adobe confirms critical Flash zero-day bug

For the second time in the last four weeks, Adobe has told users that hackers are exploiting an unpatched bug in Flash Player, again by embedding malicious code inside a Microsoft Office document.

In a security advisory issued Monday, Adobe said that attackers are exploiting the vulnerability by embedding Flash attack files within a Microsoft Word document sent as an email attachment.

adobe did not spell out a patch timeline for the newest Flash zero-day.
Four weeks ago, Adobe issued a similar warning about a different flaw that hackers manipulated via attack code tucked inside Excel spreadsheet attachments.
Later, RSA Security confirmed that the March vulnerability had been used by cybercriminals to gain a foothold on its corporate network, then steal information related to the company's SecurID two-factor authentication products.
Adobe patched last month's Flash bug on March 21.
Mila Parkour, the independent security researcher who reported the newest Flash flaw to Adobe, said attackers have inserted a malicious Flash Player file into a Word document named "Disentangling Industrial Policy and Competition Policy," which is then sent to targeted recipients as an attachment.
The email message's subject heading is "Disentangling Industrial Policy and Competition Policy in China," Parkour said in an April 6 entry on her Contagio Malware Dump blog.
One message that Parkour cited claimed the attached Word document was a copy of the American Bar Association's Antitrust Source newsletter, hinting that the target recipients may have been the legal departments at corporations or government agencies.
People seeing the email and attachment could be expected to fall for the ruse, since the most recent issue of Antitrust Source does contain an article by the same name. The legitimate article is available on the newsletter's Web site ( download PDF document).
Parkour has reported numerous vulnerabilities to Adobe, including one last September in the company's popular PDF viewer, Adobe Reader.
The Flash vulnerability also exists in Adobe Reader and Acrobat, both of which include code that renders Flash content inserted into PDF files.
"At this time, Adobe is not aware of any attacks via PDF targeting Adobe Reader and Acrobat," Adobe said in the advisory.



Last month, Microsoft urged Excel users to install and run the Enhanced Mitigation Experience Toolkit (EMET) to block those attacks, and said that Excel 2010 was not susceptible to the exploit because of its "Protected View" sandbox.
While those same recommendations may apply today for Word, Microsoft was not immediately able to confirm that to Computerworld.
Currently, only one anti-virus firm, Commtouch, has issued a signature that tags the rogue Word document as a threat, according to VirusTotal, a free service that analyzes suspicious files.
Flash vulnerabilities are an attractive target to hackers, said Andrew Storms, director of security operations at nCircle Security. When asked if the rash of Flash flaws meant it was time for companies to consider ditching the browser plug-in, Storms answered, "That's going to be incredibly hard due to the pervasiveness of its use in valid business systems."
