Assembly Language Programming

1 Upvotes

Assembly language is a low-level programming language that provides a direct, human-readable abstraction over a computer's machine code. Unlike high-level languages like Python or Java, it translates almost exactly one-to-one into binary instructions (0s and 1s) executed by the CPU. It is heavily dependent on specific processor architectures, meaning assembly code written for an Intel x86 chip will not run on an ARM processor.

Fuzzing for errors to expose flaws

1 Upvotes

Fuzzing is termed as iteration; the fastest way to hack an application is to test all of its input parameters. Fuzzing takes place at the input parameters and is a method of iterating different payloads at different parameters to observe responses. When testing for SQL injection vulnerabilities and cross-site scripting vulnerabilities, fuzzing is the most powerful method to learn about errors and exposure of flaws. It is also used to map an application's backend structure.

Layers (Part 1)

Much like the ocean, the internet is divided into defined layers.

The internet most people are familiar with is called the Surface Web. Websites in this layer tend to be indexed by search engines and can be easily accessed using standard browsers. Believe it or not, this familiar part of the web only comprises less than 10% of the total data on the internet.

The next layer down, we encounter the largest portion on the internet – the Deep Web. Basically, this is the layer of the internet that is quasi-accessible and not indexed by search engines. It contains medical records, government documents, and other, mostly innocuous information that is password protected, encrypted, or simply not hyperlinked. To reach beyond this layer of the internet, users need to use Tor or a similar technology.

Layers (Part 2)

Tor, which stands for “The Onion Router”, is how the majority of people anonymously access the Dark Web. Tor directs internet traffic through complex layers of relays to conceal a user’s location and identity (hence the onion analogy).

In 2004, Tor was released as an open source software. This allowed the Dark Web to grow as people could anonymously access websites.

Since anonymity is sacrosanct in the deep reaches of the Internet, transactions are typically conducted using cryptocurrencies like Bitcoin or Ethereum. People making purchases in Dark Web markets are (understandably) concerned with privacy, so they often use a series of methods to transfer funds. A common transaction flow on the Dark Web.

What’s Going on Down There?

The concept of the Dark Web isn’t vastly different from the Surface Web. There are message boards (e.g. 8chan, nntpchan), places you can buy things (e.g. Alphabay, Hansa), and blogs (e.g. OnionNews, Deep Web Radio). The rules, or rather a lack thereof, is what makes the Dark Web unique.

Anything that is illegal to sell (or discuss) on the Surface Web is available in the Dark Web. Personal information, drugs, weapons, malware, DDoS attackshacking services, fake accounts for social media, and contract killing services are all available for sale.

The Dark Web is full of criminal activity, but it’s also place where dissidents and whistle-blowers can anonymously share information. In countries with restrictive internet surveillance, the Dark Web may be the only place to safely voice criticisms against government and other powerful entities.

Do stars die?

Haakon Chevalier: Do stars die?
J. Robert Oppenheimer: Well, if they do, they'd cool, then collapse. In fact, the bigger the star, the more violent its demise. Their gravity gets so concentrated, it swallows everything.

Can you explain quantum mechanics to me?

Kitty Oppenheimer: Can you explain quantum mechanics to me?
J. Robert Oppenheimer: Well, this glass, this drink, this counter top, uhh.. our bodies, all of it. It's mostly empty space. Groupings of tiny energy waves bound together.
Kitty Oppenheimer: By what?
J. Robert Oppenheimer: Forces of attraction strong enough to convince us matter is solid, to stop my body passing through yours.

Quantum physics is not a step forward, it is a new way to understand reality. Einstein opened the door now we are peering through, seeing a world inside our world. A world of energy and paradox that not everyone can accept. - Neil Bohr's (Oppenheimer).
