A computer breakdown at the International Space Station may require a spacewalk by astronauts.

Nasa said a back-up computer on the outside of the orbiting lab was not responding to commands.

The main computer, called an MDM or multiplexer-demultiplexer, is working and the six-man crew is in no danger. But the computers control some robotic functions that would be needed for next week's planned visit by a private SpaceX supply ship.

Mission Control will decide shortly as to whether the computer can be repaired or must be replaced.

NSA deny knowing about the Heartbleed bug

The National Security Agency (NAS) have denied that they were aware of the Heratbleed bug before the security flaw was made public.

Reports that NSA or any other part of the government were aware of the so-called Heartbleed vulnerability before April 2014 are wrong. The Federal government was not aware of the recently identified vulnerability in OpenSSL until it was made public in a private sector cybersecurity report.

The Federal government relies on OpenSSL to protect the privacy of users of government websites and other online services.

If the Federal government, including the intelligence community, had discovered this vulnerability prior to last week, it would have been disclosed to the community responsible for OpenSSL.

– Spokesperson Caitlin Hayden, US National Security Council

The denial follows claims the NSA had known about the flaw for up to two years.

The US National Secutiry Agency (NSA) has knew about the Heartbleed bug for at least two years before it was revealed, according to Bloomberg.

One person 'familiar with the matter' told the news agency that the NSA preferred to keep the bug secret in order to harvest the private data the flaw exposed.

UK agencies in more than 1,900 Facebook data requests

British law enforcement agencies made more than 1,900 requests for data on Facebook users in last six months of 2013, according to results published by the social network.

There were 1,906 requests submitted to Facebook for user data related to criminal cases Between July and December 2013.

Colin Stretch, Facebook's general counsel, said: "Facebook's mission is to give people the power to share, and to make the world more open and connected. Sometimes, the laws of a country interfere with that mission, by limiting what can be shared there."

These requests affected 2,277 different accounts, and Facebook announced that more than 70% of these requests saw some data produced.

Globally there were more than 28,000 requests for data, but the number of requests by government agencies in the UK actually fell in the second half of the year.

Larry Zelvin, a Department of Homeland Security official who runs an agency centre that monitors and responds to emerging cyber threats said on his White House blog:

"While there have not been any reported attacks or malicious incidents involving this particular vulnerability at this time, it is still possible that malicious actors in cyberspace could exploit unpatched systems."

Security firm sets up website on Heartbleed bug

Finnish security firm Codenomicon has set up a dedicated website to give people information about the Heartbleed bug, a glitch in the OpenSSL security product that may have put internet users' personal data at risk.

It comes after the firm, along with Google Security, revealed earlier this week that the bug had gone undetected for two years and could be used by hackers to steal sensitive information such as passwords.

Public urged to 'change every password' amid bug worry

Several technology companies have urged the public to reset their passwords amid fears of a major security problem with a product used to protect people's personal data.

The Heartbleed bug affects OpenSSL, which many companies use to protect sensitive information, including people's password.

A small padlock icon appears on websites using OpenSSL to reassure users, but the loophole in the programme could have left it open to exploitation by hackers.

Blogging platform Tumblr posted a public notice about the bug, advising users to "take some time to change your passwords everywhere - especially your high-security services like email, file storage, and banking".

Finnish security company Codenomicon also said it would be "a good idea" to change potentially vulnerable passwords.
