Every PC in China could be at risk of being taken over by malicious hackers because of flaws in compulsory government software.

Terms-Of-Service and other website policies form the foundation of your relationship with social networking sites, online businesses, and other Internet communities. But most people become aware of these terms only when there's a problem. TOSBack was created to help you monitor the policies for the websites you use everyday, and show how they change over time.

The Current State of Web Privacy, Data Collection, and Information Sharing

Computer users often dismiss Internet security best practices because they find them inconvenient, or because they think the rules don't apply to them. Many cling to the misguided belief that because they don't bank or shop online, that bad guys won't target them. The next time you hear this claim, please refer the misguided person to this blog post, which attempts to examine some of the more common -- yet often overlooked -- ways that cyber crooks can put your PC to criminal use.

Their system, dubbed retransmission steganography (RSTEG), relies on sender and receiver using software that deliberately asks for retransmission even when email data packets are received successfully. "The receiver intentionally signals that a loss has occurred. The sender then retransmits the packet but with some secret data inserted in it," he says in a preliminary research paper (www.arxiv.org/abs/0905.0363). So the message is hidden among the teeming network traffic.

The team of researchers [...] studied connection patterns in the BitTorrent file-sharing network — one of the largest and most popular P2P systems today. They found that over the course of weeks, groups of users formed communities where each member consistently connected with other community members more than with users outside the community. [...] Given the impact of this threat, the researchers developed a technique that prevents accurate classification by intelligently hiding user-intended downloading behavior in a cloud of random downloading.

DPI technology raises privacy concerns because it can involve the inspection of information sent from one end user to another.

A European Union directive, which Britain was instrumental in devising, comes into force which will require all internet service providers to retain information on email traffic, visits to web sites and telephone calls made over the internet, for 12 months.

Computerised records of all 250 million journeys made by individuals in and out of the UK each year will be kept for up to 10 years. The government says the database is essential in the fight against crime, illegal immigration and terrorism.
