Since early 2020, an unknown hacker has been adding thousands of malicious servers to the Tor network. These servers intercept SSL traffic from cryptocurrency exchange sites. In addition, they are using their servers to switch crypto addresses and redirect them to their own wallets. This hacker has gotten so bad that his servers have been shut down at least three times by the Tor project. These bad exit nodes have been taking up roughly a quarter of the exit capacity of the Tor network, which peaked in February 2021 at 27%.
Unidentified hacker has been adding thousands of malicious servers to the Tor network since early 2020
Since early 2020, the Tor Network has been under attack from an unknown hacker who is adding malicious servers. These servers send anonymized traffic back to the normal internet. While they have been shut down several times, the hacker continues to add new malicious nodes to the network.
One of the ways the attacker is deanonymizing users is by using BGP hijacking. This technique works by falsely announcing that an IP range is owned by a particular entity. This enables the attacker to monitor and blackhole traffic through the network.
The hacker has also been targeting financial technology and entities that deal in financial activity. They are not affiliated with any nation state and have focused their attacks on retrieving sensitive business data. Their latest targets are unnamed. However, their activities are timed to coincide with the Russian invasion of Ukraine. While the ultimate recipient of the stolen data is still unknown, this conflict makes the environment ideal for the attacker.
Attackers are intercepting SSL traffic on cryptocurrency exchange websites
Cryptocurrency exchange websites are not safe from attackers intercepting SSL traffic. This type of attack is known as cryptocurrency clipping. This involves the theft of cryptocurrency during a transaction. This is accomplished through malware that replaces the intended wallet address with the threat actor’s address. This attack can occur if the exchange website does not follow good security practices.
To prevent this kind of attack, exchanges need to ensure that their SSL certificates are strong. There are a number of ways attackers can steal cryptocurrency. Some of the methods include communicating anonymously, impersonating web sites, or stealing cryptocurrency. The top two routes are local and shortest path. These are the fastest paths that include the least number of AS hops.
Users can find bad exit nodes on a list provided by the Tor Project
Tor is an encrypted anonymity browser, but it can be vulnerable to attacks if it has many bad exit nodes. In 2007 an attacker named Dan Egerstad used five Tor exit nodes to intercept thousands of private emails, instant messages, and email account credentials. He also managed to capture emails from a range of ministries and embassies. The results of his experiment convinced Egerstad that Tor is no better than a man-in-the-middle and that exit nodes can be used as an easy way to spy on users. He also suspected that governments were funding expensive exit nodes to spy on users.
If users want to avoid getting caught by bad exit nodes, they can use Tor DNS. It can also help websites identify Tor traffic so that they can whitelist or treat it differently. For example, a site could ask its users to sign in before posting, or may require a shared IP address.
Bitcoin nodes exceed Ethereum’s in number
Both Bitcoin and Ethereum have huge networks. However, the number of Bitcoin nodes remains higher than that of Ethereum. While Ethereum had the most nodes at the beginning of 2019, it quickly dropped in January, losing more than 3,000 nodes. Many of those were shut down after the hard fork in December, which caused Ethereum’s blockchain to completely change.
While there are some differences between Bitcoin and Ethereum, they have many similarities. While Bitcoin has over 7,000 nodes, Ethereum has more than three times as many. This means that it requires more administrative skills to run. To run a node, a computer must have 8MB of bandwidth, 4GB of RAM, and at least 2 cores to process transactions.
TOR is a good way to browse the web anonymously
TOR is a free software application that allows you to browse the web anonymously. It is a modified version of the popular Firefox browser that is designed to leave no trace of your web surfing. It is available for all operating systems and can be downloaded from the Tor Browser website. Once installed, it runs as an executable file on your computer and automatically clears all browsing history, leaving only your bookmarks and downloaded files.
TOR allows users to browse the internet anonymously by masking their IP address and network connection. By doing this, they can access websites that are not regulated. These include pirated content and sites that sell illegal substances. Tor is also used by journalists to circumvent censorship. The anonymity provided by Tor allows them to publish articles that would otherwise not be published. In fact, most of the popular news organizations have dark web versions of their regular websites.
