Alleged leaked documents about the NSA's XKeyscore snooping software appear to show the paranoid agency is targeting Tor and Tails users, Linux Journal readers – and anyone else interested in online privacy.Apparently, this configuration file for XKeyscore is in the divulged data, which was obtained and studied by members of the Tor project and security specialists for German broadcasters NDR and WDR. <a href="http://pubads.g.doubleclick.net/gampad/jump?iu=/6978/reg_security/front&sz=300x250%7C300x600&tile=3&c=33U7ZK6qwQrMkAACSrTugAAAP1&t=ct%3Dns%26unitnum%3D3%26unitname%3Dwww_top_mpu%26pos%3Dtop%26test%3D0" target="_blank"> <img src="http://pubads.g.doubleclick.net/gampad/ad?iu=/6978/reg_security/front&sz=300x250%7C300x600&tile=3&c=33U7ZK6qwQrMkAACSrTugAAAP1&t=ct%3Dns%26unitnum%3D3%26unitname%3Dwww_top_mpu%26pos%3Dtop%26test%3D0" alt=""></a> In their analysis of the alleged top-secret documents, they claim the NSA is, among other things:Specifically targeting Tor directory servers Reading email contents for mentions of Tor bridges Logging IP addresses used to search for privacy-focused websites and software And possibly breaking international law in doing so. We already know from leaked Snowden documents that Western intelligence agents hate Tor for its anonymizing abilities. But what the aforementioned leaked source code, written in a rather strange custom language, shows is that not only is the NSA targeting the anonymizing network Tor specifically, it is also taking digital fingerprints of any netizens who are remotely interested in privacy.

These include readers of the Linux Journal site, anyone visiting the website for the Tor-powered Linux operating system Tails – described by the NSA as "a comsec mechanism advocated by extremists on extremist forums" – and anyone looking into combining Tails with the encryption tool Truecrypt.If something as innocuous as Linux Journal is on the NSA's hit list, it's a distinct possibility that El Reg is too, particularly in light of our recent exclusive report on GCHQ – which led to a Ministry of Defence advisor coming round our London office for a chat.

If you take even the slightest interest in online privacy or have Googled a Linux Journal article about a broken package, you are earmarked in an NSA database for further surveillance, according to these latest leaks.This is assuming the leaked file is genuine, of course.Other monitored sites, we're told, include HotSpotShield, FreeNet, Centurian, FreeProxies.org, MegaProxy, privacy.li and an anonymous email service called MixMinion. The IP address of computer users even looking at these sites is recorded and stored on the NSA's servers for further analysis, and it's up to the agency how long it keeps that data.The XKeyscore code, we're told, includes microplugins that target Tor servers in Germany, at MIT in the United States, in Sweden, in Austria, and in the Netherlands. In doing so it may not only fall foul of German law but also the US's Fourth Amendment.

Yesterday, news broke that Google has been stealth downloading audio listeners onto every computer that runs Chrome, and transmits audio data back to Google. Effectively, this means that Google had taken itself the right to listen to every conversation in every room that runs Chrome somewhere, without any kind of consent from the people eavesdropped on. In official statements, Google shrugged off the practice with what amounts to “we can do that”.It looked like just another bug report. "When I start Chromium, it downloads something." Followed by strange status information that notably included the lines "Microphone: Yes" and "Audio Capture Allowed: Yes".

Without consent, Google’s code had downloaded a black box of code that – according to itself – had turned on the microphone and was actively listening to your room.A brief explanation of the Open-source / Free-software philosophy is needed here. When you’re installing a version of GNU/Linux like Debian or Ubuntu onto a fresh computer, thousands of really smart people have analyzed every line of human-readable source code before that operating system was built into computer-executable binary code, to make it common and open knowledge what the machine actually does instead of trusting corporate statements on what it’s supposed to be doing. Therefore, you don’t install black boxes onto a Debian or Ubuntu system; you use software repositories that have gone through this source-code audit-then-build process. Maintainers of operating systems like Debian and Ubuntu use many so-called “upstreams” of source code to build the final product.Chromium, the open-source version of Google Chrome, had abused its position as trusted upstream to insert lines of source code that bypassed this audit-then-build process, and which downloaded and installed a black box of unverifiable executable code directly onto computers, essentially rendering them compromised. We don’t know and can’t know what this black box does. But we see reports that the microphone has been activated, and that Chromium considers audio capture permitted.

This was supposedly to enable the “Ok, Google” behavior – that when you say certain words, a search function is activated. Certainly a useful feature. Certainly something that enables eavesdropping of every conversation in the entire room, too.Obviously, your own computer isn’t the one to analyze the actual search command. Google’s servers do. Which means that your computer had been stealth configured to send what was being said in your room to somebody else, to a private company in another country, without your consent or knowledge, an audio transmission triggered by… an unknown and unverifiable set of conditions.Google had two responses to this. The first was to introduce a practically-undocumented switch to opt out of this behavior, which is not a fix: the default install will still wiretap your room without your consent, unless you opt out, and more importantly, know that you need to opt out, which is nowhere a reasonable requirement. But the second was more of an official statement following technical discussions on Hacker News and other places. That official statement amounted to three parts (paraphrased, of course):
