Video Title: What is Brute Force Attack? How it's done? | [Hindi] In this video i will tell you what is brute force attack and how it's done. We will see in detail how it works. we will also discuss what is dictionary attack and how its different from brute force attack. Everything explained in Hindi. Extra info: In cryptography, a brute-force attack consists of an attacker trying many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found. Alternatively, the attacker can attempt to guess the key which is typically created from the password using a key derivation function. This is known as an exhaustive key search. A brute-force attack is a cryptanalytic attack that can, in theory, be used to attempt to decrypt any encrypted data (except for data encrypted in an information-theoretically secure manner). Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the task easier. When password guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because a brute-force search takes too long. Longer passwords, passphrases and keys have more possible values, making them exponentially more difficult to crack than shorter ones. Brute-force attacks can be made less effective by obfuscating the data to be encoded making it more difficult for an attacker to recognize when the code has been cracked or by making the attacker do more work to test each guess. One of the measures of the strength of an encryption system is how long it would theoretically take an attacker to mount a successful brute-force attack against it. Brute-force attacks are an application of brute-force search, the general problem-solving technique of enumerating all candidates and checking each one. ----------------------------------------- Like our Facebook page: https://www.facebook.com/DesiScientistReal/ Follow us on Twitter: https://twitter.com/DS_Asli

Hello Friends, In This Video, I'm Gonna Show You How You Can Encrypt & Decrypt The Hash String With The Help Of Hashlib Python Module Python-Hash-Cracker Program - https://goo.gl/zs3ikD HASHING : - If you need secure hashes or message digest algorithms, then Python’s standard library has you covered in the hashlib module. It includes the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 as well as RSA’s MD5 algorithm. Python also supports the adler32 and crc32 hash functions, but those are in the zlib module. One of the most popular uses of hashes is storing the hash of a password instead of the password itself. Of course, the hash has to be a good one or it can be decrypted. Another popular use case for hashes is to hash a file and then send the file and its hash separately. Then the person receiving the file can run a hash on the file to see if it matches the hash that was sent. If it does, then that means no one has changed the file in transit Cryptographic hashes are used in day-day life like in digital signatures, message authentication codes, manipulation detection, fingerprints, checksums (message integrity check), hash tables, password storage and much more. They are also used in sending messages over a network for security or storing messages in databases. There are many hash functions defined in the “hashlib” library in python. Some of the most used hash functions are: MD5: Message digest algorithm producing a 128 bit hash value. This is widely used to check data integrity. It is not suitable for use in other fields due to the security vulnerabilities of MD5. SHA: Group of algorithms designed by the U.S's NSA that are part of the U.S Federal Information processing standard. These algorithms are used widely in several cryptographic applications. The message length ranges from 160 bits to 512 bits. Functions associated : encode() : Converts the string into bytes to be acceptable by hash function. digest() : Returns the encoded data in byte format. hexdigest() : Returns the encoded data in hexadecimal format. ----------------------------------------------------------------------------------------------------------- Hope This Video Is Helpful For You ► Connect with me! ◄ Facebook - http://bit.ly/2tbOg3b Google+ - http://bit.ly/2jrWz6g Instagram - http://bit.ly/2tbR14z Reddit - https://bit.ly/2J5Vqfm ★★★Watch my most recent videos playlist★★★ Kali Linux - https://goo.gl/36M3JD Deep Web - https://goo.gl/7ueKNh Python Coding - https://goo.gl/dCtyrS Java Coding - https://goo.gl/oxFo8W Basic Computer - https://goo.gl/kwFXM3 Hacking - https://goo.gl/vjT916 Games Benchmark - https://goo.gl/eshw3T Gaming - https://goo.gl/mLuQwf Notepad Tricks -https://goo.gl/3uapMJ CMD Tricks - https://goo.gl/x1KH8C Facebook Tricks - https://goo.gl/1JV9Fz Problem Solved - https://goo.gl/eJwjXq Gmail Tricks - https://goo.gl/fSpbaB And talking about subscribing, please subscribe to my channel, if you enjoyed this video and want more how-to, Thanks so much for watching!

The basics of computer security, and how to make sure you protect your information. Let's cover computer security. The first thing we're going to talk about is something called a dictionary attack which has to do with your passwords. When creating your passwords, some sites require extremely specific and complicated passwords, which is actually a bit unnecessary. The type of attacks they're trying to gaurd you from are dictionary attacks. Dictionary attacks are programmed to try every word in the dictionary, or in its own database of common words and passwords, as the password for a large mass of usernames. If your password is Kangaroo, they're probably going to break into your account. Most passwords aren't this simple, but that doesn't matter. They attack such a massive amount of accounts that they only need a few passwords that are relatively simple. When creating a password, you want to use different cases, numbers, and symbols, but one of the most effective ways to create a good password is to throw some random letters in there (ex: kangarooSyCA67). Also, stay away from sequential numbers. Phishing, another thing to watch out for, is emails or webpages that mimic other valid sites to try and trick people into entering their personal information, though the site truly isn't connected to the site it's trying to mimic. In general, two ways to safeguard from these attacks are checking the address in the browser and to open a new browser and go to the website that is claiming to contact you. Let's also discuss encryption and HTTPS. If you are at Starbucks trying to access your bank account, you have reason to be suspicious that someone could see and take your information. You will want to look for a green HTTPS instead of HTTP at the beginning of the web address. That means that the site you're sending your information to is encrypting your passwords and other information, scrambling up data according to a code that only they know. In general, whenever you're showing private or sensitive information, check for HTTPS. A few other general tips: don't share passwords between important accounts. If a site you use gets hacked into, your password may be compromised regardless of its strength. Also, don't download strange files. If you don't recognise the file type like .pdf, .txt, .jpg, be wary. Some of these files you download can be very powerful and even run your computer from the inside. Lastly, keep your software updated, particularly software that interacts with the internet. One way that information can be compromised is when 'bad guys' find holes and gaps in security of older versions of softwares. Those bugs have been patched in newer versions, so if you keep everything updated, you'll avoid lots of problems. These are all very basic things you should know about how to keep your information safe on your computer.

Dictionary attack This uses a simple file containing words that can, surprise surprise, be found in a dictionary. In other words, if you will excuse the pun, this attack uses exactly the kind of words that many people use as their password. Cleverly grouping words together such as ‘letmein’ or ‘superadministratorguy’ will not prevent your password from being cracked this way - well, not for more than a few extra seconds. 2. Brute force attack This method is similar to the dictionary attack but with the added bonus, for the hacker, of being able to detect non-dictionary words by working through all possible alpha-numeric combinations from aaa1 to zzz10. It’s not quick, provided your password is over a handful of characters long, but it will uncover your password eventually. Brute force attacks can be shortened by throwing additional computing horsepower, in terms of both processing power - including harnessing the power of your video card GPU - and machine numbers, such as using distributed computing models and zombie botnets. 3. Rainbow table attack A rainbow table is a list of pre-computed hashes - the numerical value of an encrypted password, used by most systems today - and that’s the hashes of all possible password combinations for any given hashing algorithm mind. The time it takes to crack a password using a rainbow table is reduced to the time it takes to look it up in the list. 4. Phishing There's an easy way to hack: ask the user for his or her password. A phishing email leads the unsuspecting reader to a faked online banking, payment or other site in order to login and put right some terrible problem with their security. Why bother going to the trouble of cracking the password when the user will happily give it you anyway? 5. Social engineering Social engineering takes the whole ‘ask the user’ concept outside of the inbox that phishing tends to stick with and into the real world. A favourite of the social engineer is to telephone an office posing as an IT security tech guy and simply ask for the network access password. You’d be amazed how often this works. Some even have the necessary gonads to don a suit and name badge before walking into a business to ask the receptionist the same question face to face.

What is SIDE-CHANNEL ATTACK? What does SIDE-CHANNEL ATTACK mean? SIDE-CHANNEL ATTACK meaning - SIDE-CHANNEL ATTACK definition - SIDE-CHANNEL ATTACK explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, a side-channel attack is any attack based on information gained from the physical implementation of a cryptosystem, rather than brute force or theoretical weaknesses in the algorithms (compare cryptanalysis). For example, timing information, power consumption, electromagnetic leaks or even sound can provide an extra source of information, which can be exploited to break the system. Some side-channel attacks require technical knowledge of the internal operation of the system on which the cryptography is implemented, although others such as differential power analysis are effective as black-box attacks. Many powerful side-channel attacks are based on statistical methods pioneered by Paul Kocher. Attempts to break a cryptosystem by deceiving or coercing people with legitimate access are not typically called side-channel attacks: see social engineering and rubber-hose cryptanalysis. For attacks on computer systems themselves (which are often used to perform cryptography and thus contain cryptographic keys or plaintexts), see computer security. The rise of Web 2.0 applications and software-as-a-service has also significantly raised the possibility of side-channel attacks on the web, even when transmissions between a web browser and server are encrypted (e.g., through HTTPS or WiFi encryption), according to researchers from Microsoft Research and Indiana University. General classes of side channel attack include: Cache attack — attacks based on attacker's ability to monitor cache accesses made by the victim in a shared physical system as in virtualized environment or a type of cloud service. Timing attack — attacks based on measuring how much time various computations take to perform. Power-monitoring attack — attacks that make use of varying power consumption by the hardware during computation. Electromagnetic attack — attacks based on leaked electromagnetic radiation, which can directly provide plaintexts and other information. Such measurements can be used to infer cryptographic keys using techniques equivalent to those in power analysis or can be used in non-cryptographic attacks, e.g. TEMPEST (aka van Eck phreaking or radiation monitoring) attacks. Acoustic cryptanalysis — attacks that exploit sound produced during a computation (rather like power analysis). Differential fault analysis — in which secrets are discovered by introducing faults in a computation. Data remanence — in which sensitive data are read after supposedly having been deleted. Row hammer — in which off-limits memory can be changed by accessing adjacent memory. Optical - in which secrets and sensitive data can be read by visual recording using a high resolution camera, or other devices that have such capabilities (see examples below). In all cases, the underlying principle is that physical effects caused by the operation of a cryptosystem (on the side) can provide useful extra information about secrets in the system, for example, the cryptographic key, partial state information, full or partial plaintexts and so forth. The term cryptophthora (secret degradation) is sometimes used to express the degradation of secret key material resulting from side-channel leakage. A cache side-channel attack works by monitoring security critical operations such as AES T-table entry or modular exponentiation multiplicand accesses. Attacker then is able to recover the secret key depending on the accesses made (or not made) by the victim, deducing the encryption key. Also, unlike some of the other side-channel attacks, this method does not create a fault in the ongoing cryptographic operation and is invisible to the victim.

Background video :- https://www.youtube.com/watch?v=fZ5pORFxUxw What is Hacking? Hacking is identifying weakness in computer systems or networks to exploit its weaknesses to gain access. Example of Hacking: Using password cracking algorithm to gain access to a system. Database :- A database is a data structure that stores organized information. Most databases contain multiple tables, which may each include several different fields. For example, a company database may include tables for products, employees, and financial records. Each of these tables would have different fields that are relevant to the information stored in the table. Nearly all e-commerce sites uses databases to store product inventory and customer information. These sites use a database management system (or DBMS), such as Microsoft Access, FileMaker Pro, or MySQL as the "back end" to the website. By storing website data in a database, the data can be easily searched, sorted, and updated. This flexibility is important for e-commerce sites and other types of dynamic websites. Rainbow Attack :- A rainbow table attack is a type of hacking wherein the perpetrator tries to use a rainbow hash table to crack the passwords stored in a database system. A rainbow table is a hash function used in cryptography for storing important data such as passwords in a database. Sensitive data are hashed twice (or more times) with the same or with different keys in order to avoid rainbow table attacks. Hashing :- Hashing is the transformation of a string of characters into a usually shorter fixed-length value or key that represents the original string. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. It is also used in many encryption algorithms. Salting :- Salting out is a purification method that utilizes the reduced solubility of certain molecules in a solution of very high ionic strength. Salting out is typically, but not limited to, the precipitation of large biomolecules such as proteins.The conformation of large biomolecules in vivo is typically controlled by hydrophobic and hydrophillic interactions with the cellular environment. These interactions largely govern the molecule's final conformation by folding in such a way that most hydrophobic functional groups are shielded from the polar cellular environment. To achieve this conformation the molecule folds in such a way that all of the hydrophobic parts of a molecule are aggregated together and the hydrophillic groups are left to interact with the water. In the case of proteins it is the charged amino acids that allow selective salting out to occur. Charged and polar amino acids such as glutamate, lysine, and tyrosine require water molecules to surround them to remain dissolved. In an aqueous environment with a high ionic strength, the water molecules surround the charges of the ions and proteins. At a certain ionic strength, the water molecules are no longer able to support the charges of both the ions and the proteins. The result is the precipitation of the least soluble solute, such as proteins and large organic molecules. Dictionary attack:- In cryptanalysis and computer security, a dictionary attack is a form of brute force attack technique for defeating a cipher or authentication mechanism by trying to determine its decryption key or passphrase by trying hundreds or sometimes millions of likely possibilities, such as words in a dictionary.A dictionary attack is based on trying all the strings in a pre-arranged listing, typically derived from a list of words such as in a dictionary (hence the phrase dictionary attack). In contrast to a brute force attack, where a large proportion of the key space is searched systematically, a dictionary attack tries only those possibilities which are deemed most likely to succeed. #harikarki #hacking #salting_Rainbow_hasing

If both match values stored within a locally stored table, the user is authenticated for a connection. Password strength is a measure of the difficulty involved in guessing or breaking the password through cryptographic techniques or library-based automated testing of alternate values. A weak password might be very short or only use alphanumberic characters, making decryption simple. A weak password can also be one that is easily guessed by someone profiling the user, such as a birthday, nickname, address, name of a pet or relative, or a common word such as God, love, money or password. That is why CUPP has born, and it can be used in situations like legal penetration tests or forensic crime investigations.

Technical talks from the Real World Crypto conference series.

Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols to secure wireless computer networks. WPA was developed as a replacement to broken Wired Equivalent Privacy (WEP) in 2003, as WEP can be bypassed very easily and effectively using various methods. WPA uses RC4 stream cipher based Temporal Key Integrity Protocol (TKIP) to ensure that each data packet is transmitted with a unique encyption key, thereby preventing the types of attacks that compromised WEP. However, a flaw has been discovered on TKIP based WPA which relies on chopchop attack used in WEP cracking. TKIP is much stronger than a cyclic redundancy check algorithm (CRC) used in WEP, but not as strong as the Counter Mode Cipher Block Chaining Message Authentication Code Protocol, Counter Mode CBC-MAC Protocol (CCMP) algorithm used in WPA2. WPA2 uses Advanced Encryption Standard (AES) block cipher based CCMP. It is stronger than TKIP in both privacy and integrity. Authentication modes : 1. WPS mode 2. Personal mode 3. Enterprise mode WPS mode has already been discussed and exploited in previous video. Here is the link in case you missed it https://youtu.be/7XYt5-FeB7U PERSONAL or PSK mode was designed for home and small office networks. This mode use a 256 bit key to encrypt the network traffic, which is a string of 64 hexadecimal digits or a passphrase of 8 to 63 printable ASCII characters. If ASCII characters are used, the 256 bit key is calculated by applying the PBKDF2 key derivation function to the passphrase, using the SSID as the salt and 4096 iterations of HMAC-SHA1. Personal mode is available in both WPA and WPA2, which is the topic of this video. The authentication takes place by a 4-way handshake in both PSK and Enterprise mode. Initial authentication is done using PSK or EAP exchange to ensure the client is authenticated to the access point (AP). After PSK authentication a secret shared key is generated called Pairwise Master Key (PMK). The PSK is derived from a password that is put through PBKDF2-SHA1 as the cryptographic hash function. In a pre-shared-key network, the PSK is actually the PMK. For AP and client exchanging encrypted data, both need to have the right key(s) installed. Each time a client (Supplicant) associates to an AP (Authenticator), new Pairwise Temporal/Transient Key (PTK) is generated, which is unique for each connected client. In case of Broadcast and Multicast frames, all clients use the same Groupwise Temporal Key (GTK) that don’t require a new generation for each association. The function to generate a Pairwise Temporal Key (PTK) is known as a Pseudo Random Function (PRF): PTK = PRF(PMK + ANonce + SNonce + APMAC + SMAC) Nonce is number used once and are pseudo random numbers. Anonce and Snonce are AP and STA (client or station) nonces respectively. APMAC and SMAC are MAC addresses of AP and STA respectively. The 4-way handshake takes place as follows : 1. The AP sends Anonce to the client or STA. 2. The client sends the SNonce to the AP protected by a cryptographic hash (HMAC-SHA1) called Message Integrity Code (MIC) for integrity of this message. The message also includes the Robust Security Network Information Element (RSN IE). 3. The AP constructs and sends the GTK and a sequence number together with another MIC. 4. The Supplicant acknowledges the installation of PTK and GTK afterwards, encrypted Unicast and Broadcast/Multicast transmission can start now. Using aircrack along with a dictionary or crunch bruteforce can take from fews minutes to lifetime to crack the passkey. However, the things can be accelerated using rainbow tables, precomputed hashes, GPU power. A long random alphanumeric password containing upper and lower case letters and special characters is beyond the of computation power available till now. However no one uses such passwords instead people use passwords which are easy to remember, and hence are vulnerable to such attacks. So, in order to speeed up the cracking process what we do is that we use precomputed hashes, and hence saving the conversion time required to hash all words in a wordlist. Rainbow tables come up with precomputed hashes for most commonly used SSIDs. Remember two different SSIDs with same password will produce different hashes. So in order to use rainbow table against captured hash one must ensure first the target network's SSID is present in most commonly used 1000 SSIDs list. In case your SSID is not present in that list then you cant create your own rainbow table using tools like RainbOwCrack. We can make our own hashes for a partical SSID using genpmk and testing the created hashes against captured hash using another tool called cowpatty. In order to use GPU power we can use tools loke oclHashCat, which uses GPU power along with CPU power to crack the wifi key. I am going to cover all these topics in coming tutorials.

Dictionary Attack - An attempt to gain illicit access to a computer system by using a very large set of words to generate potential passwords. A dictionary attack is based on trying all the strings in a pre-arranged listing, typically derived from a list of words such as in a dictionary (hence the phrase dictionary attack). In contrast to a brute force attack, where a large proportion of the key space is searched systematically, a dictionary attack tries only those possibilities which are deemed most likely to succeed. Dictionary attacks often succeed because many people have a tendency to choose short passwords that are ordinary words or common passwords, or simple variants obtained, for example, by appending a digit or punctuation character. Dictionary attacks are relatively easy to defeat, e.g. by using a passphrase or otherwise choosing a password that is not a simple variant of a word found in any dictionary or listing of commonly used passwords. BRUTEFORCE TECHNIQUE - In cryptography, a brute-force attack consists of an attacker trying many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found. Alternatively, the attacker can attempt to guess the key which is typically created from the password using a key derivation function. This is known as an exhaustive key search. ---------------Links Password Checker Online - https://howsecureismypassword.net/ password generator - http://passwordsgenerator.net/ safePassword - https://www.safepasswd.com/

Cybersecurity is a set of techniques to protect the secrecy, integrity, and availability of computer systems and data against threats. In today’s episode, we’re going to unpack these three goals and talk through some strategies we use like passwords, biometrics, and access privileges to keep our information as secure, but also as accessible as possible. From massive Denial of Service, or DDos attacks, to malware and brute force password cracking there are a lot of ways for hackers to gain access to your data, so we’ll also discuss some strategies like creating strong passwords, and using 2-factor authentication, to keep your information safe.

Edit 2: ------------------- Newest version: http://www.youtube.com/watch?v=EzG-hNaNO58 ------------------- Edit: ------------------- New version: http://www.youtube.com/watch?v=EzG-hNaNO58 ------------------- After my 1st attempt almost a year ago, I thought I'd give it another try. Before finishing the code & compare the generated permutation to a dictionary I thought I'd give the "Brute Force" method a try. What do you know it works :D The keyboard stoke emulation is so fast that the flash component in IE cannot cope with it, so the keystrokes aren't displayed instantly. Also that's why not all words are being recognized, some missing, especially the 5 & 6 letter words. Being slower might have a higher success rate. Sometimes it gets so flooded that it becomes so slow. I worked a little on it one day this week, then worked on it from 6 Am to 3 Pm one shot, little tweaks after lunch to make it compatible to work on my desktop. BTW, in theory, you can get infinite score, since being so fast generates more time than being lost by count down timer. Got bored so decided I'll reach the 1*10^6 & stop :P This is the brute force version where all permutations of the 6 letters are generated then input, the next version (if done) would be dictionary attack but through permutation, so all possible combination's are generated then compared to dictionary before being input. Yes, it took more than 13 minutes counting the score! :P I'm just a beginner in programming, we only learned Introduction to C++ at university (very basics), didn't really dig into programming, the logic is there but I really dunno many of the syntax as I discovered from doing this program.

What is DISTINGUISHING ATTACK? What does DISTINGUISHING ATTACK mean? DISTINGUISHING ATTACK meaning - DISTINGUISHING ATTACK definition - DISTINGUISHING ATTACK explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, a distinguishing attack is any form of cryptanalysis on data encrypted by a cipher that allows an attacker to distinguish the encrypted data from random data. Modern symmetric-key ciphers are specifically designed to be immune to such an attack. In other words, modern encryption schemes are pseudorandom permutations and are designed to have ciphertext indistinguishability. If an algorithm is found that can distinguish the output from random faster than a brute force search, then that is considered a break of the cipher. A similar concept is the known-key distinguishing attack, whereby an attacker knows the key and can find a structural property in cipher, where the transformation from plaintext to ciphertext is not random. To prove that a cryptographic function is safe, it is often compared to a random oracle. If a function would be a random oracle, then an attacker is not able to predict any of the output of the function. If a function is distinguishable from a random oracle, it has non-random properties. That is, there exists a relation between different outputs, or between input and output, which can be used by an attacker for example to find (a part of) the input. Example Let T be a sequence of random bits, generated by a random oracle and S be a sequence generated by a pseudo-random bit generator. Two parties use one encryption system to encrypt a message M of length n as the bitwise XOR of M and the next n bits of T or S respectively. The output of the encryption using T is truly random. Now if the sequence S cannot be distinguished from T, the output of the encryption with S will appear random as well. If the sequence S is distinguishable, then the encryption of M with S may reveal information of M. Two systems S and T are said to be indistinguishable if there exists no algorithm D, connected to either S or T, able to decide whether it is connected to S or T. A distinguishing attack is given by such an algorithm D. It is broadly an attack in which the attacker is given a black box containing either an instance of the system under attack with an unknown key, or a random object in the domain that the system aims to emulate, then if the algorithm is able to tell whether the system or the random object is in the black box, one has an attack. For example, a distinguishing attack on a stream cipher such as RC4 might be one that determines whether a given stream of bytes is random or generated by RC4 with an unknown key. Classic examples of distinguishing attack on a popular stream cipher was by Itsik Mantin and Adi Shamir who showed that the 2nd output byte of RC4 was heavily biased toward zero. In another example, Souradyuti Paul and Bart Preneel of COSIC have shown that the XOR value of the 1st and 2nd outputs of RC4 is also non-uniform. Significantly, both the above theoretical biases can be demonstrable through computer simulation.
