A newly discovered software superbug is putting your private information at risk. The virus, called Heartbleed, gives hackers a way around encryption technology to access passwords, credit-card numbers and other data. Some experts say as much as 66% of the web has been infected.
Users are being advised to change their passwords, but should first confirm that the affected site is no longer vulnerable.
Another threat has emerged for users of Windows XP. The government of the US and UK have advised computer users to stop using Internet Explorer, the most popular search engine on the internet, until Microsoft can fix a security flaw that allows hackers to launch attacks that could completely compromise their systems. This threat is specific to the millions of people still using Windows XP, for which Microsoft has stopped providing security updates.
