A web application can be attacked via brute force by taking a word list of known pages, for instance from a popular content management system, and simply requesting each known page then analyzing the HTTP response code to determine if the page exists on the target server. DirBuster is a tool that does exactly this. The attacker has now found a potential directory of interest within this application. This dictionary will detect weaknesses of this kind. The application WebRoot.
With this software, the different aspects of a wireless network will be taken care of and thus let you gain easy access. The tool takes care of monitoring, attacking, testing and cracking. Traditionally, cracking and sniffing software are associated with the Linux platform. As a matter of fact, the majority of the variants available for the other platforms have a background on this platform. Nevertheless, no matter the platform of choice, you can always find a suitable tool.
RainbowCrack is a brute force software developed to work on the Windows platform though there is still a variant for the Linux platform. With the software, you will get full time-memory trade-off tool suites and a unified rainbow table file format on all supported operating systems. Ophcrack is a brute force software that is available to the Mac users. However, the software is also available to the users on the Linux and Windows platform as well.
With this tool, you will have access to a wide range of target system as well as the ability to conduct scheduled scans. You can also see Cyber Security Tools. Brute force is a technique that is used in predicting the password combination. It is one of the techniques available for cracking passwords though it is mostly suitable for simple password combinations.
So as to ensure success this does not imply, it cannot be done alone. In the majority of the cases, the software in this category is used for experimental purposes especially testing the strength of various measures. Nevertheless, there have been reports on the use of the tools for illegal activities such as hacking.
Brute Force Software are very useful especially in the cases where one has forgotten their password, and there are no means of accessing it back. AirGrab Password v. HTTPBrute v. The tool will be able to perform brute force attacks to retrieve a lost password for a given Authentication response.
MD5 is the only hashing algorithm Brutezip v. Since each request appears to come from a different IP address, you cannot block these attacks simply by blocking the IP address. To further complicate things, some tools try a different username and password on each attempt, so you cannot lock out a single account for failed password attempts. The most obvious way to block brute-force attacks is to simply lock out accounts after a defined number of incorrect password attempts.
Account lockouts can last a specific duration, such as one hour, or the accounts could remain locked until manually unlocked by an administrator.
However, account lockout is not always the best solution, because someone could easily abuse the security measure and lock out hundreds of user accounts. In fact, some Web sites experience so many attacks that they are unable to enforce a lockout policy because they would constantly be unlocking customer accounts.
Account lockout is sometimes effective, but only in controlled environments or in cases where the risk is so great that even continuous DoS attacks are preferable to account compromise. In most cases, however, account lockout is insufficient for stopping brute-force attacks. Consider, for example, an auction site on which several bidders are fighting over the same item. An attacker could use the same technique to block critical financial transactions or e-mail communications. You may also consider locking out authentication attempts from known and unknown browsers or devices separately.
The Slow Down Online Guessing Attacks with Device Cookies article proposes protocol for lockout mechanism based on information about if specific browser have been already used for successful login. The protocol is less susceptible to DoS attacks than plain account locking out and yet effective and easy to implement. As described, account lockouts are usually not a practical solution, but there are other tricks to deal with brute force attacks.
First, since the success of the attack is dependent on time, an easy solution is to inject random pauses when checking a password. Note that although adding a delay could slow a single-threaded attack, it is less effective if the attacker sends multiple simultaneous authentication requests. Another solution is to lock out an IP address with multiple failed logins. The problem with this solution is that you could inadvertently block large groups of users by blocking a proxy server used by an ISP or large company.
Another problem is that many tools utilize proxy lists and send only a few requests from each IP address before moving on to the next.
