s of commonly used credentials, or real user credentials, obtained via security breaches or the dark web. Bots systematically attack websites and try these lists of credentials, and notify the attacker when they gain access.Types of Brute Force AttacksSimple brute force attack—uses a systematic approach to ‘guess’ that doesn’t rely on outside logic.Hybrid brute force attacks—starts from external logic to determine which password variation may be most likely to succeed, and then continues with the simple approach to try many possible variations.Dictionary attacks—guesses usernames or passwords using a dictionary of possible strings or phrases.Rainbow table attacks—a rainbow table is a precomputed table for reversing cryptographic hash functions. It can be used to guess a function up to a certain length consisting of a limited set of characters.Reverse brute force attack—uses a common password or collection of passwords against many possible usernames. Targets a network of users for which the attackers have previously obtained data.Credential stuffing—uses previously-known password-username pairs, trying them against multiple websites. Exploits the fact that many users have the same username and password across different systems.omg and Other Popular Brute Force Attack ToolsSecurity analysts use the THC-omg tool to identify vulnerabilities in client systems. omg quickly runs through a large number of password combinations, either simple brute force or dictionary-based. It can attack more than 50 protocols and multiple operating systems. omg is an open platform; the security community and attackers constantly develop new modules.omg brute force attackOther top brute force tools are:Aircrack-ng—can be used on Windows, Linux, iOS, and Android. It uses a dictionary of widely used passwords to breach wireless networks.John the Ripper—runs on 15 different platforms including Unix, Windows, and OpenVMS. Tries all possible combinations using a dictionary of possible passwords.L0phtCrack—a tool for cracking Windows passwords. It uses rainbow tables, dictionaries, and multiprocessor algorithms.Hashcat—works on Windows, Linux, and Mac OS. Can perform simple brute force, rule-based, and hybrid attacks.DaveGrohl—an open-source tool for cracking Mac OS. Can be distributed across multiple computers.Ncrack—a tool for cracking network authentication. It can be used on Windows, Linux, and BSD.Weak Passwords that Enable Brute Force AttacksToday, individuals possess many accounts and have many passwords. People tend to repeatedly use a few simple passwords, which leaves them exposed to brute force attacks. Also, repeated use of the same password can grant attackers access to many accounts.Email accounts protected by weak passwords may be connected to additional accounts, and can also be used to restore passwords. This makes them particularly valuable to hackers. Also, if users don’t modify their default router password, their local network is vulnerable to attacks. Attackers can try a few simple default passwords and gain access to an entire network.Some of the most commonly found passwords in brute force lists include: date of birth, children’s names, qwerty, 123456, abcdef123, a123456, abc123, password, asdf, hello, welcome, zxcvbn, Qazwsx, 654321, 123321, 000000, 111111, 987654321, 1q2w3e, 123qwe, qwertyuiop, gfhjkm.Strong passwords provide better protection against identity theft, loss of data, unauthorized access to accounts etc.How to Prevent Brute Force Password HackingTo protect your organization from brute force password hacking, enforce the use of strong passwords. Passwords should:Never use information that can be found online (like names of family members).Have as many characters as possible.Combine letters, numbers, and symbols.Be different for each user account.Avoid common patterns.As an administrator, there are methods you can implement to protect users from brute force password cracking:Lockout policy—you can lock accounts after several failed login attempts and then unlock it as the administrator.Progressive delays—you can lock out accounts for a limited amount of time after failed login attempts. Each attempt makes the delay longer.Captcha—tools like reCAPTCHA require users to complete simple tasks to log into a system. Users can easily complete these tasks while brute force tools cannot.Requiring strong passwords—you can force users to define long and complex passwords. You should also enforce periodical password changes.Two-factor authentication—you can use multiple factors to authenticate identity and grant access to accounts.Brute Force Attack Prevention with ImpervaImperva Bot Protection monitors traffic to your website, separating bot traffic from real users and blocking unwanted bots. Because almost all brute force attacks are carried out by bots, this goes a long way towards mitigating the phenomenon.Bot Protection follows three stages to identify bad bots. It classifies traffic using a signature database with millions of known bot variants. When identifying a suspected bot, it performs several types of inspection to classify the bot as legitimate, malicious or suspicious. Finally, suspicious bots are challenged, to see if they can accept cookies and parse Javascript.Imperva WAF also protects against manual brute force attacks. When a user makes repeated attempts to access a system, or successively attempts different credentials following a pattern, Imperva will detect this anomalous activity, block the user and alert security staff.
Это полезно, если вы хотите выполнить Гибридную атаку hashcat. Если вы хотите работать только с первым экземпляром символа, вы можете использовать 1s или просто использовать echo -n 'Odessa77' hashcat -stdout -j '1s Dp ip' Odаботать. Далее

Brutus AET2 Платформа: Windows Последний релиз программы был в 2000 году. В таблицы записывается только начало и конец каждой такой цепочки. Вот пример: Создание простого словаря: echo WORd word Генерируем простое правило. Используя случайные правила. Атака по словарю Описание атаки по словарю Атака по словарю или «прямой режим» - это очень простой вид атаки. Спешу обрадовать: чаще всего используется именно она, причем как на Windows серверах, так и серьезных cisco-системах. Посовещавшись, мы выяснили, что выбор так разнится, что можно составить настоящий джентльменский набор из проверенных программ. Особенно когда они меняются и на Wi-Fi роутере и WPS на нем вообще отключен. Для просмотра через консоль потребуются права администратора и пара команд - этот способ более удобен для точечного вытаскивания профиля к нужной сети: netsh wlan show profile netsh wlan export profile name"Insert profile name" folderC:WlanProfiles.

Вышеприведённый пароль соответствует простому, но распространённому паттерну (образцу). Ответ прост: регулярные выражения слишком медленны. Преимущество использования файлов.hcmask, которые представляют собой обычный текст, в том, что эти файлы позволяют пользователям hashcat иметь предопределённые и хорошо работающие маски,ть.
