Journalists and citizens living under repressive regimes alike depend on the encrypted Tor browser to surf the web anonymously. But in certain cases, an attacker can figure out which dark web site a user is trying to access by passively monitoring Tor traffic, and even reveal the identity of servers hosting sites on the Tor network.
Russian hackers have figured out a way to use Twitter to communicate with malware that’s infected target computers, allowing them to cover their tracks while making their way into confidential government computer systems.
The hackers upload special images to the social media site that stealthily transmit directions to installed malware that can then steal files or other unwanted actions, reported the Financial Times. The advantage of this approach is that targeted computer systems don’t register the intrusion. It looks like just another Tweet.
GitHub, the hugely popular and sometimes controversial website for hosting software development, has officially raised its second round of funding. Just like the first it’s a whopper: $250 million, which now values the company at $2 billion, GitHub told the Wall Street Journal.

Over the last year, researchers have been teasing out the problems with making flash look like disks. While these problems are less of an issue for notebook and desktop users, they are a big problem for servers.
