Canadian researchers have uncovered a vast electronic spying operation that infiltrated computers and stole documents from government and private offices around the world, including those of the Dalai Lama, The New York Times reported on Saturday.

In a report provided to the newspaper, a team from the Munk Center for International Studies in Toronto said at least 1,295 computers in 103 countries had been breached in less than two years by the spy system, which it dubbed GhostNet.

Embassies, foreign ministries, government offices and the Dalai Lama’s Tibetan exile centers in India, Brussels, London and New York were among those infiltrated, said the researchers, who have detected computer espionage in the past.

They found no evidence U.S. government offices were breached.

The researchers concluded that computers based almost exclusively in China were responsible for the intrusions, although they stopped short of saying the Chinese government was involved in the system, which they described as still active.

For the first time, researchers filmed the transfer of HIV from infected to uninfected T cells through structures called virological synapses. The study, conducted by researchers at Mount Sinai School of Medicine, in New York, NY, and the Center for Biophotonics Science and Technology, University of California, Davis, could lead to new methods to block the transmission of HIV. The study published in the March 27 edition of Science.

Researchers captured the video, shown here, by creating a molecular clone of infectious HIV that contains green fluorescent protein. They then used quantitative, high-speed 3-D video microscopy to record both viral particle formation and transmission of the virus between T cells.

Three possible security issues with Google Docs recently uncovered by researcher Ade Barkah. It turns out that an image embedded into a protected document is given a URL which is not protected, allowing anyone who knows or guesses it to see the image regardless of permissions or even the existence of the document.

Barkah also pointed out that once you’ve shared a document with another person, that person can see diagram revisions from any point before they gained access, forcing you to create a new document if you need to redact something.

The last issue, the mechanics of which he disclosed only to Google, affects the document-sharing invitation forwarding system, which can allow somebody access to your documents after you’ve removed their permissions.

Google made a blog post to respond to these concerns, saying that they “do not pose a significant security risk,” but are being investigated. We previously discussed a sharing bug in Google Docs that was fixed earlier this month.
