4chan leaked

remember. This tells us that it is useless to enhance the complexity of passwords in the face of offline brute-force cracking attacks. When the password file is leaked To prevent offline cracking attacks after password files are leaked, we need to take some protection measures. A general solution is mentioned in Microsoft's report: Encrypt each password and store the key in the hardware security module (H

the file, run the following command: $ Gpg filename.txt Then, you will be prompted to enter the password, and then the file will be decrypted.Document Digital Signature A digital signature is very similar to signing your name at the end of a letter or an important file. It indicates that this file was indeed issued by you. By digital signature, it calculates the SHA1 hash value of the entire file content, and then attaches this value to the end of the signature. If the file content is tamper

cracking. In the Burpsuite test, we can find that the password cracking time has been greatly extended. In this way, if the password is slightly more complex, in addition, the appropriate pause time can basically effectively defend against brute-force cracking.Of course, the most effective way to defend against brute-force cracking is to add a verification code to the logon page. Although some verification codes can also be broken through, if the verification code is slightly more complex, just

Some common attack methods and simple defense methods in WEB Development SQL InjectionThe most common attack method, called SQL injection, is to insert SQL commands into Web forms to submit or enter query strings for domain names or page requests, and finally fool the server to execute malicious SQL commands, for example, most of the previous VIP member passwords leaked by many video websites are exposed by submitting query characters through WEB form

developers. In fact, in many cases, session IDs may be leaked. For example, if the session ID is transmitted through GET data, this sensitive identity information may be exposed. Some users may cache links with session IDs, add them to favorites, or send them to emails. Cookies are a relatively secure mechanism, but users can disable cookies on the client! In some IE versions, there are also serious security vulnerabilities. The most famous one is th

little shy now and you need to coax it to get the answer. This is often called "Boolean-value-based" SQL injection, which plays a role in the previous demonstration of "merge-Based Query" and "error-based" solutions. But this is not foolproof. Let's look at another way. This time we will have some patience. Patient waiting for leakage: time-based blind Injection The success of all real-time solutions is based on the assumption that the app will leak information through HTML output. In the previ

compilation.To open the memory leak report again: Enablememoryleakreporting.In general, it is turned on by default. This opens the full debug mode, and if a memory leak occurs, a report file is generated, and a dialog box appears when the IDE is running. Similar report file: Xxx_memorymanager_eventlog.txt2. The report file consists of two parts and is run append each time.The first part is the details of the leak, showing the details of each memory block that is not freed. Cases:A memory block

Swap partitions are also useful during program testing. For example, the administrator can monitor the usage of Swap partitions, check whether the system memory is leaked, and check the Web Project and other applications.

, vocabulary analysis, and supplier directories to handle adjustment laws. Of course, it is not a skill that applies to all cases. The skill you choose depends on the data you protect. How can security experts protect web 2.0 security? The answer is overall planning. There is no problem in accepting web 2.0. We only need to recognize the existence of threats and create a web 2.0 Security toolset to maximize its effectiveness. This Toolkit should be based on commercial goals to establish a strate

Many Web programs store the path and file name of Access database files in the database connection file. Once the contents of these connection files are leaked, traces are exposed no matter how complex the database file name is. In this case, you can use the ODBC data source method. Even if the content of the connection file is leaked, others can only know the name of the ODBC Data Source used by the webs

Gosney of Stricture Consulting Group can compile the first one hundred common passwords based on some data. "The Last leak affected 130,324,429 users. We have not yet mastered the keys encrypted by Adobe for their passwords. However, because Adobe chooses symmetric key encryption based on hash, select ECB mode, and each password uses the same key. Combined with a large amount of known plain text and generous information provided by users in the password prompt, it is not difficult for us to sum

zval of the array itself is changed to 0, then we can judge that this array is a garbage. This principle is actually very simple. Suppose the refcount of array a is equal to m, and n elements in a point to a. If m is equal to n, then the result of the algorithm is m minus n, m-n = 0, then a is garbage. If m> n, then the result of the algorithm is m-n> 0, so a is not garbage. What does m = n represent? The refcount OF a comes from the zval element contained in array a. It means that no variabl

measures are usually used to block unauthorized access at the network and operating system level and integrate them into non-customized or customized application systems. However, databases that actually store information often only use the standard username/password mechanism for protection. Oracle Database 10 Gb is the best implementation for this mechanism. Even so, if the password leaks, the protection will no longer exist. Oracle databases can provide more protection through Oracle Virtual

In recent years, many companies have leaked data, causing heavy losses to the affected enterprises and even facing the risk of bankruptcy. In order to prevent the occurrence of leaks, many enterprises have installed Super eye computer monitoring softwareOne of the functions is the real-time alarm of employees on the computer. Once there is any violation, an alarm will be triggered immediately, for example: insert a USB flash drive alarm, copy to USB f
