YouTube has become a daily habit for millions all over the world, but it looks like there has been some malicious activity on the website -- which may have affected more than 100,000 users over a 30 day period.

According to Trend Micro, they have been monitoring the activity on YouTube over the past couple of months and have found that the attack comes in the form of ads that are present on the site. While the ads themselves have no malicious content, the issue seems to occur when the ad is clicked. Although these ads should be monitored and screened by YouTube, some have seemed to slip through the cracks, redirecting to malicious websites that could cause infections.

Malicious advertisements have popped up on websites such as YouTube, Amazon and Yahoo, part of a sophisticated campaign to spread malware, Cisco said Monday.

When encountered, the malicious advertisements cause a person to be redirected to a different website, which triggers a download based on whether the computer is running Windows or Apple’s OS X, wrote Armin Pelkmann, a threat researcher. The network has been nicknamed Kyle and Stan due to those names appearing in subdomains of more than 700 websites the attackers have set up to distribute the malware, Pelkmann wrote.

Cryptolocker is being flogged over YouTube by vxers who have bought advertising space, researchers Vadim Kotov and Rahul Kashyap have found.

The duo who will present at the upcoming Virus Bulletin 2014 conference in Seattle wrote in a paper advertisement networks was a viable way to flog virus and trojans.

The British government claims that the purpose of surveillance is to display the online trends in cities around the world.

According to Edward Snowden British authorities spy on what people are doing on some of the world’s most popular social media sites, such as YouTube, Facebook, Twitter etc. Nevertheless, he denies spying on specific users. The latest information from the National Security Agency was obtained by NBC News with journalist Glenn Greenwald, who was the first to report on Snowden’s documents about NSA and United Kingdom espionage while on the staff of the Guardian. NBC doesn’t mention when the information was received.

Viber, a mobile messenger app that allows users to make phone calls and send text messages and images for free, also gives up plenty of free user data to anyone who wants to listen.

According to researchers from the University of New Haven (UNH) in Connecticut, US, Viber's app sends user messages in unencrypted form - including photos, videos, doodles, and location images.

All of that rich data from users is also stored unencrypted on Viber's servers, rather than being deleted immediately, and is accessible without credentials, just a link, the UNH researchers said. 

The National Security Agency and the FBI are tapping directly into the central servers of nine leading U.S. Internet companies, extracting audio and video chats, photographs, e-mails, documents, and connection logs that enable analysts to track foreign targets, according to a top-secret document obtained by The Washington Post.

The program, code-named PRISM, has not been made public until now. It may be the first of its kind.

The NSA prides itself on stealing secrets and breaking codes, and it is accustomed to corporate partnerships that help it divert data traffic or sidestep barriers.
