They're part of the scary-Muslims-are-hiding-under-your-bed network and have a long track record of "finding" al Qaeda videos that may or may not be authentic. Here's an earlier example of their work.

Edit event
US analysts obtain two new videos of a man thought to be Osama bin Laden (see September 7, 2007 and September 11, 2007) before al-Qaeda makes them available on the internet. A video released on September 7 is obtained by the US-based SITE Institute, which provides it “to government agencies and news organizations at a time when many well-known jihadist Web sites had been shut down in a powerful cyberattack by unknown hackers.” The next tape is obtained by a web designer known as “Laura Mansfield,” who manages “to scoop al-Qaeda by publicly unveiling its new video, a feat she has accomplished numerous times since 2002.” Although SITE’s founder Rita Katz declines to comment on how it obtained the video, the Washington Post says that SITE, Mansfield, and others like them obtained the videos, whose release was publicly announced in advance, “using a combination of computer tricks, personal connections and ingenuity to find and download password-protected content.”

His beard is shorter than in his 2004 video, and is black, leading some to speculate it had been dyed, and others to suggest the Bin Laden in the video is an impersonator. The video's title, The Solution, appears in the top left corner of the video frame. The video running time is approximately 26 minutes. . . .
Several peculiarities in the video raise questions regarding its authenticity:
Osama bin Laden sports the trimmer, blacker beard and the same clothing he wore in the October 2004 video.
The video freezes at about 1 minute and 58 seconds, and motion only resumes again at 12:30.
The video then freezes again at 14:02, and remains frozen until the end.
All references to current events, such as the 62nd anniversary of the US atomic bombing of Japan, and Sarkozy and Brown being the leaders of France and the UK, respectively, occur when the video is frozen.
The words spoken when the video is in motion contain no references to contemporary events and could have been made before the US invasion of Iraq.
