New 'Hardened' Tor Browser Protects Users From FBI Hacking (vice.com)

An anonymous reader quotes an article from Motherboard: According to a new paper, security researchers are now working closely with the Tor Project to create a "hardened" version of the Tor Browser, implementing new anti-hacking techniques which could dramatically improve the anonymity of users and further frustrate the efforts of law enforcement...

"Our solution significantly improves security over standard address space layout randomization (ASLR) techniques currently used by Firefox and other mainstream browsers," the researchers write in their paper, whose findings will be presented in July at the Privacy Enhancing Technologies Symposium in Darmstadt, Germany.

The researchers say Tor is currently field-testing their solution for an upcoming "hardened" release, making it harder for agencies like the FBI to crack the browser's security, according to Motherboard. "[W]hile that defensive advantage may not last for too long, it shows that some in the academic research community are still intent on patching the holes that their peers are helping government hackers exploit."

      Yeah, that pretty much sums it up.

      Why, is that a problem?

      See, these government guys are different from those government guys, who have an entirely different agenda from that government branch, because it's really coming from the authority of this government office, rather than that government office, and has an entirely different chain of command with entirely different officials from an entirely different Congressional committee.

      Nobody wakes up in the morning and says "Today, I'm going to oppress my fellow citizens and make their lives worse!". Instead, all the government employees work toward the common goal of "advance America's interests", according to their specific areas of expertise. One group says build a thing because it helps America, and another group says to break it because it helps America's enemies.

      Apart from paranoia, there is no reason to believe that either side isn't doing their best. If you trust that the Tor researchers (stemming from DARPA and the U.S. Navy) could possibly create a secure network, and trust that the Tor project could possibly create a secure browser, then you can trust that this browser is secure. That the government who funded it is now also trying to break it has little effect on how trustworthy the software itself actually is.

    You have multiple countries with teams of very smart people working to crack everything crackable that protects privacy--because what allows private communication necessarily allows evasion of monitoring.

    Of course, there are a lot of kinds of monitoring. Most obvious categories include:

    1. Good purposes (attacking and/or defending against terrorists/child pornographers/organized crime/repressive regimes; tracking and blocking malware and other electronic attacks; etc...).
    2. Middle-ground purposes (arguably ends-justify-the-means-behavior like violating some civil liberties while hunting white-collar criminals, child support nonpayment grey market income, doing propaganda against people in group #1).
    3. Bad purposes (hunting political opposition, tracking and classifying people based on their political opinions or other things that should be prevented by freedom of speech, finding dirt for blackmail, gathering evidence of and prosecuting someone for common civil ordinance violations and petty crimes in a way which chills and stifles free speech and gives the monitoring agency unfettered power, etc...)

      Well yeah I agree with you that the impression that TOR is mainly used to commit crimes is bad, but the paper has mentioned the FBI hacking in its introduction.

      The technique they use is in fact per-function ASLR, and probably the places it can be used are as vast as for ASLR. Its not just limited to TBB or Firefox.

      The thing people fail to understand is that you can always do thought-crime securely when you have secure anonymity. It is in the very definition of anonymity. And this whole thing is a trade-off, but the modern enlightened stance is that freedom is more important than suppression of though-crime and hence anonymity that works is hugely desirable.

      Crimes with a physical component are different. For example, selling counterfeit objects (passports, ...) via a Tor hidden service still requires physical shipping, and that is where you can get them, even with Tor being perfectly secure. It does take a bit of traditional police-work though, and that is slow and tedious and law enforcement in many places has apparently gotten fat and lazy.

    For Tor? It has and very much so. When the FBI quite criminally (for most non-US citizen affected) mass-hacked Freedom Hosting (and they hacked everybody they could, quite a few users of entirely legal services among them), nobody that had updated their Tor Browser when prompted was affected. It was just people that used the old one for two weeks or so longer than they should have. And here is the kicker: Tor Browser releases have change notes and these state what was patched. And there is the patched source, and you can see what was fixed. And that is exactly how low-cost vulnerability-finding works.

    So yes, unpatched is pretty central to how secure it is. Requires some minimal understanding on how things work in the real world to see that though.
