Perfect Anonymity: Is It Possible to Achieve It

November 17th, 2022

Different needs and different threat models lead to misunderstanding between people. Let’s say you want to leave the most anonymous comment possible on some social network. What do you need for it? VPN? Tor? A SSH tunnel? Well, it’s enough to buy any SIM card and a used phone at a nearest shop, then go at a considerable distance from where you live, insert one into another, post your message, and sink the phone. You have accomplished your mission at 100%.

But what if you don’t want to just leave a one-time comment or hide your IP address from some site? What if you want such an advanced level of anonymity that will make up the most intricate puzzle without any room for any hack on any level? And also conceal the very fact of using anonymity tools on the way? This is what I’m going to talk about in this piece.

The perfect anonymity is mostly a dream, like everything perfect. But it doesn’t mean you can’t approach it pretty close. Even if you’re being identified by system fingertips and other means, you can still stay undistinguishable from the mass of general Web users. In this article I’m going to explain how to achieve this.

This is not a call to action, and the author by no means calls for any illegal actions or violation of any laws of any states. Consider it just a fantasy about “if I were a spy.”

Basic protection level

The basic level of protection and anonymity looks roughly this way: client → VPN/TOR/SSH tunnel → target.

Actually, this is just a slightly more advanced version of a proxy which allows to substitute your IP. You won’t achieve any real or quality anonymity this way. Just one incorrect or default setting in notorious WebRTC, and your actual IP is revealed. This type of protection is also vulnerable to node compromising, fingerprints, and even simple log analysis with your provider and data center.

By the way, there is a common opinion that a private VPN is better than a public one since the user is confident about his system setup. Consider for a moment that someone knows your outside IP. Hence, he knows your data center too. Hence, the data center knows the server this IP belongs to. And now just imagine how difficult it is to determine which actual IP connected to the server. What if you are the only one client there? And if they are numerous, for example 100, it’s getting much harder.

Current Trends in Bitcoin

April 22nd, 2022

Bitcoin is built on the notion that money is any object, or any sort of record, accepted as payment for goods and services and repayment of debts in a given country or socio-economic grouping. Bitcoin uses cryptography, or mathematical equations, to control the creation and transfer of money, rather than relying on governments and central banking authorities. Transfers for loans, sales, purchases or any other methods of payment can be processed by anybody, using a desktop, smart phone, tablet, or laptop. This is all possible without the need for a financial institution to act as an intermediary or recording agent.

Created in 2009, Bitcoin is a digital currency introduced as open source software by an MIT student named Satoshi Nakamoto. There is much speculation as to whether Satoshi is an actual person, or a collection of individuals using a pseudonym. Bitcoin are minted by a process termed mining, in which specialized computer hardware complete complex mathematic equations and are rewarded with a block of bitcoins. This process takes about 10 minutes and the current block rewards 25 bitcoins. The block reward will be halved to 12.5 bitcoins in 2017 and again approximately every four years thereafter. By 2140 there will be roughly 21 million bitcoins in existence.

This week has shown a whirlwind of activity with business owners of all stripes getting on track with Bitcoin. From small businesses in New Orleans, to the Sacramento Kings of the NBA accepting Bitcoin for ticket sales and team paraphernalia, to casinos in Las Vegas, Bitcoin is popping up everywhere. Venture Capitalist Chris Dixon believes Bitcoin may reach $100,000 if it becomes the primary means of ecommerce ( Wired ). The CEO of a major online retailer was quoted as saying “Other retailers will not want to miss out, Bitcoin market is growing by 30% per month.” This same retailer saw a 5% increase in sales the first day it accepted Bitcoin. Zynga Games, one of the largest online gaming companies, responsible for Farmville, Castleville, and a host of others also began accepting Bitcoin for in game financial transactions. After the five Big Banks said no to money from marijuana dispensaries and growers, Colorado’s legal marijuana dispensary industry turned to Bitcoin ( ZeroHedge ). The IRS has also recently launched a campaign that allows taxes to be paid with Bitcoin. There has been Bitcoin ATM’s popping up in cities such as Vancouver, Ottawa, and a Bratislava Slovakia shopping mall. Recently, the New York City Bitcoin ATM was put on hold until a public hearing under the jurisdiction of the New York State Department of Financial Services can be held.
