The Tor Project to Beef Up Privacy with Next-Generation of Onion Services

The Tor Project to Beef Up Privacy with Next-Generation of Onion Services

November 03, 2017Mohit Kumar
The Tor Project has made some significant changes to its infrastructure by improving the way the 'onion' network protects its users' privacy and security. Since the beginning, the largest free online anonymity network has been helping users browse the web anonymously, and its onion service provides a network within which encrypted websites can be run anonymously. However, the infrastructure design and encryption behind the service has become little outdated, eventually leaving it vulnerable to potential and resourceful attackers. Tor network has become such a potential target that even Zerodium, a company that acquires and resells zero-day exploits, is ready to pay $1 million for Tor zero-day exploits . Keeping these concerns in mind, the Tor Project has been working to upgrade its infrastructure over the past four years, and the good news is… A few weeks ago, the Tor Project announced the release of Tor 0.3.2.1-alpha that includes support for the next generati
Core Tor Contributor Leaves Project; Shutting Down Important Tor Nodes

Core Tor Contributor Leaves Project; Shutting Down Important Tor Nodes

Another blow to the Tor Project : One of the Tor Project's earliest contributors has decided to quit the project and shut down all of the important Tor nodes under his administration. Lucky Green was part of the Tor Project before the anonymity network was known as TOR. He probably ran one of the first 5 nodes in the TOR network at its inception and managed special nodes inside the anonymity network. However, Green announced last weekend that "it is no longer appropriate" for him to be part of the Tor Project, whether it is financially or by providing computing resources. TOR, also known as The Onion Router , is an anonymity network that makes use of a series of nodes and relays to mask its users' traffic and hide their identity by disguising IP addresses and origins. The TOR network is used by privacy-conscious people, activists, journalists and users from countries with strict censorship rules. Crucial and Fast TOR Nodes to be Shut Down Soon Alongs

How Spies Could Unmask Tor Users without Cracking Encryption

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
Tor Network Is Under Attack through Directory Authority Servers Seizures

Tor Network Is Under Attack through Directory Authority Servers Seizures

December 23, 2014Swati Khandelwal
Tor has been targeted once again, but this time at a much larger scale. A new attack on Tor network reportedly would either completely shut it down worldwide or turn it into evil network. This time Tor – an internet browser which allows people to maintain their anonymity online by protecting their location – is warning its users of a cyber attack that quietly seized some of its network specialized servers called Directory Authorities (DA) , the servers that help Tor clients to find Tor relays in the anonymous network service. Tor network architecture relies on ten Directory Authorities whose information is hardcoded into Tor clients. These directory authorities are located in the Europe and United States, and maintain the signed list of all the verified exit relays of the Tor network, and according to experts, attack on these backbone servers can "incapacitate" the overall architecture of Tor. " The Tor Project has learned that there may be an attempt to incapacit
OnionDuke APT Malware served through Tor Network

OnionDuke APT Malware served through Tor Network

The malicious Russian Tor exit node , which was claimed to be patching binary files, is actually distributing a malware program to launch cyber-espionage attacks against European government agencies. The group behind the rogue Tor exit node had likely been infecting files for more than a year, causing victims to download and install a backdoor file that gave hackers full control of their systems. Last month Josh Pitts of Leviathan Security Group uncovered a malicious Tor exit node that wraps Windows executable files inside a second, malicious Windows executable. But when Artturi Lehtiö of F-Secure carried out an in-depth research, he found that the exit node was actually linked to the notorious Russian APT family MiniDuke . " MiniDuke " previously infected government agencies and organizations in more than 20 countries via a modified Adobe PDF email attachment . MiniDuke malware is written in assembly language with its tiny file size (20KB), and uses hijacke

Attackers Compromise TOR Network to De-Anonymize Users of Hidden Services

A critical vulnerability in Tor — an encrypted anonymizing network considered to be one of the most privacy oriented service, which is used by online users in order to hide their activities from law enforcement, government censors and others — was probably being used to de-anonymize the identity of Tor users, Tor project warned on Wednesday. 115 MALICIOUS ToR RELAYS WERE DE-ANONYMIZING USERS According to a security advisory , Tor Team has found a group of 115 malicious fast non-exit relays (6.4% of whole Tor network), those were actively monitoring the relays on both ends of a Tor circuit in an effort to de-anonymize users. " While we don't know when they started doing the attack, users who operated or accessed hidden services from early February through July 4 should assume they were affected, " Tor said. When you use Tor anonymizing network, your IP address remains hidden and it appears that your connection is coming from the IP address of a Tor exit rela
