Leading French presidential candidate Emmanuel Macron's campaign said on Friday it had been the target of a "massive" computer hack that dumped its campaign emails online 1-1/2 days before voters choose between the centrist and his far-right rival, Marine Le Pen.

It urged the media to be cautious about publishing details of the emails given that campaigning had ended, and publication could lead to criminal charges.

The chief constable of Sussex Police has labelled his staff “everyday heroes” for using the UK's Terrorism Act to arrest a photographer taking pictures of Hove Town Hall.

“They were in a corner because they had to let me go seeing as I hadn’t done anything – and they were so stuck they took a total abuse of power by quoting the Terror Act,” he told Daily Mail Online.

The Guardian reported: “Sussex Police were unable to answer questions on what, specifically, about Mitchell’s actions had provoked a reasonable suspicion that he was a terrorist and under what powers a member of its civilian staff had demanded an explanation and a statement from him.”

A second statement from the company, released after the service had been restored, said: "Earlier today, WhatsApp users in all parts of the world were unable to access WhatsApp for a few hours.

Dave Anderson, a digital experience expert at Dynatrace, told the BBC he believed it was likely that an update to the app had caused the problem.

Hillary Clinton today gave her first full interview since dramatically losing the US presidential election – and has placed the blame for her downfall on Russian hackers, FBI director James Comey and Wikileaks.

Just for good measure, she also blamed the media and woman-hating for her failure to take the top job.

Even now, having lost in the most spectacular fashion to probably the least-qualified US presidential candidate in history, Clinton is unable to see her and her team's own failings.

The third edition of the Chinese Encyclopaedia will be "the nation's first digital book of 'everything,'" featuring 300,000 entries of about 1,000 words each, according to the South China Morning Post, which reported the news on Sunday.

Wikipedia has a long history of partial and sometimes full blocks in China. Currently, the SCMP reports that most of the Chinese-language Wikipedia is available in mainland China, but searching for articles on sensitive topics, such as the Dalai Lama, will lead to a lost connection.

Leaked documents from Facebook's team in Australia allegedly show the social giant's ability to help advertisers target teens who feel "worthless." The documents, first revealed by The Australian, say Facebook can spot when teens "need a confidence boost."

Studies have shown that social media has been linked to lower self-esteem for young people, with strong ties between using social networks and body image issues.

Beepi doesn’t exist anymore. After burning through more than $US120 million ($158m) in capital, the start-up failed to raise more cash and shut down in February. Its roughly 270 employees cleared out of the cavernous Mountain View, California, headquarters leaving behind the ping-pong table and putting green.

In 2014 and 2015, mutual funds, hedge funds and others pumped billions into companies that they now see as overvalued, and unlikely to pull off an initial public offering.

Founded in 2013, Beepi caught on in San Francisco by giving people a fail-safe way to sell used cars online. Beepi guaranteed sellers a price, and if it couldn’t find a buyer in 30 days, it purchased the car.

A block affecting all language editions of the website detected at 8:00AM local time Saturday 29 April. The loss of availability is consistent with internet filters used to censor content in the country.

A formal judgement has been issued in approval of the administrative measure, indicating that a permanent restriction is now in place.

IoT devices can sometimes be difficult to update and might not be patched as rapidly as new exploits are discovered, which can expose users to risk. With Orbit, Cloudflare provides a barrier that will restrict IoT device communications to the Cloudflare platform, as well as providing a virtual patch.

Prince explained that instead of a device connecting directly through the public internet, an IoT device is routed through a buffer network (in this case Cloudflare) to provide security.

Linux users, the free lunch is over. Pennsylvania-based Open Source Security on Wednesday decided to stop making test patches of Grsecurity available for free.
