December 01, 2016Mohit Kumar
The critical Firefox vulnerability being actively exploited in the wild to unmask Tor users has been patched with the release of new browser updates. Both Mozilla and Tor Project has patched the vulnerability that allows attackers to remotely execute malicious code on Windows operating system via memory corruption vulnerability in Firefox web browser. Tor Browser Bundle is a repackaged version of the open-source Mozilla Firefox browser that runs connections through the Tor anonymizing network configured to hide its user's public IP address. However, the exploit code released by an unnamed online user was currently being exploited against Tor Browser users to leak the potentially identifying information of Tor users. "The security flaw responsible for this urgent release is already actively exploited on Windows systems," an official of the anonymity network wrote in an advisory published on Wednesday.  "Even though there is currently...no similar explo

Despite browsing incognito, blocking advertisements, or hiding your tracks, some websites monitor and track your every move online using a new web-tracking technique called Audio Fingerprinting . This new fingerprinting technique can be utilized by technology and marketing companies to deliver targeted advertisements as well as by law enforcement to unmask VPN or Anonymous users, without even decrypting the traffic. Researchers at Princeton University have conducted a massive privacy survey and discovered that Google, through its multiple domains, is tracking users on nearly 80 percent of all Top 1 Million Domains using the variety of tracking and identification techniques. Out of them, the newest tracking technology unearthed by the researchers is the one based on fingerprinting a machine's audio stack through the AudioContext API . "All of the top five third-parties, as well as 12 of the top 20, are Google-owned domains," the researchers note. "In fact, Goog

Mozilla asks Court to disclose Firefox Exploit used by FBI to hack Tor users
May 13, 2016Swati Khandelwal
Mozilla has filed a brief with a U.S. District Court asking the FBI to disclose the potential vulnerabilities in its Firefox browser that the agency exploited to unmask TOR users in a criminal investigation. Last year, the FBI used a zero-day flaw to hack TOR browser and de-anonymize users visiting child sex websites. Now, Mozilla is requesting the government to ask the FBI about the details of the hack so that it can ensure the security of its Firefox browser. TOR is an anonymity software that provides a safe haven to human rights activists, government, journalists but also is a place where drugs, child pornography, assassins for hire and other illegal activities has allegedly been traded. TOR Browser Bundle is basically an Internet browser based on Mozilla Firefox configured to protect the user's anonymity via Tor and Vidalia. In 2015, the FBI seized computer servers running the world's largest dark web child pornography site 'Playpen' from a web host in Lenoir, No

U.S. Supreme Court allows the FBI to Hack any Computer in the World

U.S. Supreme Court allows the FBI to Hack any Computer in the World

In Brief The US Supreme Court has approved amendments to Rule 41, which now gives judges the authority to issue search warrants, not only for computers located in their jurisdiction but also outside their jurisdiction. Under the original Rule 41, let's say, a New York judge can only authorize the FBI to hack into a suspect's computer in New York. But the amended rule would now make it easier for the FBI to hack into any computer or network, literally anywhere in the world. The Federal Bureau of Investigation (FBI) can now Hack your computers anywhere, anytime. The FBI appeared to have been granted powers to hack any computer legally across the country, and perhaps anywhere in the world, with just a single search warrant authorized by any United States judge. The U.S. Supreme Court approved yesterday a change in Rule 41 of the Federal Rules of Criminal Procedure that would let U.S. judges issue warrants for remote access to electronic devices outside their jurisdict

Clickjacking Vulnerability in Telegram Web Client The official Telegram web-client that allows its users to access messenger account over desktop's web browser is vulnerable to clickjacking web application vulnerability. Egyptian security researcher Mohamed A. Baset told The Hacker News about a flaw in Telegram that could allow an attacker to change sensitive information of a Telegram user, including password and the recovery e-mail. [ Watch Video Demo ] "Telegram web client is not protecting itself from clickjacking with the typical X-Frame-Options header but uses a JS frame busting technique to prevent the website to be iframed," Mohamed says. However, by exploiting one of HTML5 Features, Mohamed was able to open the Telegram account's settings page with a sandboxed iframe to prevent redirecting to top window, which also allows him to execute cross-site request forgery (csrf) vulnerability on the web-client. " I sent [bug report] it to them [Telegram team]

Just day before yesterday, the Tor Project Director Roger Dingledine accused the FBI of paying the Carnegie Mellon University (CMU) at least $1 Million to disclose the technique they had discovered to unmask Tor users and reveal their IP addresses. However, the Federal Bureau of Investigation has denied the claims. In a statement, the FBI spokeswoman said , "The allegation that we paid [CMU] $1 Million to hack into Tor is inaccurate." The Tor Project team discovered more than hundred new Tor relays that modified Tor protocol headers to track online people who were looking for Hidden Services , and the team believes that it belongs to the FBI in order to reveal the identity of Tor-masked IP addresses. One such IP address belongs to Brian Richard Farrell , an alleged Silk Road 2 lieutenant who was arrested in January 2014. The attack on Tor reportedly began in February 2014 and ran until July 2014, when the Tor Project discovered the flaw. Within few

T he O nion R outer (Tor) is weeping Badly! Yes, Tor browser is in danger of being caught once again by the people commonly known as " Spies ," who's one and only intention is to intrude into others' network and gather information. A team of security researchers from Massachusetts Institute of Technology (MIT) have developed digital attacks that can be used to unmask Tor hidden services in the Deep Web with a high degree of accuracy. The Tor network is being used by journalists, hackers, citizens living under repressive regimes as well as criminals to surf the Internet anonymously. A plethora of nodes and relays in Tor network is used to mask its users and make tracking very difficult. Any user when connects to Tor, the connection gets encrypted and routed through a path called a "circuit ." The request first reaches an entry node, also known as a ' Guard ' that knows the actual IP address of the user, and then goes through every ho
