An SQL injection takes advantage of SQL syntax to inject malicious commands that can read or modify a database or compromise the meaning of the original query. [13] For example, consider a web page that has two text fields which allow users to enter a username and a password.
A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
In December 2009, a major password breach of Rockyou.com occurred that led to the release of 32 million passwords. The attacker then leaked the full list of the 32 million passwords (with no other identifiable information) to the internet. Passwords were stored in cleartext in the database and were extracted through an SQL injection vulnerability.
If the script is enclosed inside a <script> element, it won't be shown on the screen. Then suppose that Bob, a member of the dating site, reaches Mallory's profile, which has her answer to the First Date question. Her script is run automatically by the browser and steals a copy of Bob's real name and email directly from his own machine.
Hold claimed the hack was perpetrated through the use of an SQL injection. [ 7 ] [ 8 ] According to a Forbes article, Hold Security said that not all the 1.2 billion credentials were stolen this way, as there were also ones that CyberVor simply bought from people that used other means, and Hold Security didn't know what the split is.
Another (lesser) benefit of a salt is as follows: two users might choose the same string as their password. Without a salt, this password would be stored as the same hash string in the password file. This would disclose the fact that the two accounts have the same password, allowing anyone who knows one of the account's passwords to access the ...
If an attacker has the hashes of a user's password, they do not need the cleartext password; they can simply use the hash to authenticate with a server and impersonate that user. [ 4 ] [ 5 ] [ 6 ] In other words, from an attacker's perspective, hashes are functionally equivalent to the original passwords that they were generated from.
Method Injection, where dependencies are provided to a method only when required for specific functionality. Setter injection, where the client exposes a setter method which accepts the dependency. Interface injection, where the dependency's interface provides an injector method that will inject the dependency into any client passed to it.
