Jess is a rule engine for the Java computing platform, written in the Java programming language. It was developed by Ernest Friedman-Hill of Sandia National Laboratories. [1] It is a superset of the CLIPS language. [1] It was first written in late 1995. [1]
BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. It runs in the Java Runtime Environment (JRE), dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures, like those in Perl and JavaScript.
If the above is stored in the executable file ./check, the shell command ./check " 1 ) evil" will attempt to execute the injected shell command evil instead of comparing the argument with the constant one. Here, the code under attack is the code that is trying to check the parameter, the very code that might have been trying to validate the ...
Editing a FreeBSD shell script for configuring ipfirewall. A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter.

It is very similar to the shell game except that cards are used instead of shells. [1] In its full form, three-card monte is an example of a classic "short con" [2] in which a shill pretends to conspire with the mark to cheat the dealer, while in fact doing the reverse. The mark has no chance whatsoever of winning, at any point in the game.
This type of shellcode does not spawn a shell, but rather instructs the machine to download a certain executable file off the network, save it to disk and execute it. Nowadays, it is commonly used in drive-by download attacks, where a victim visits a malicious webpage that in turn attempts to run such a download and execute shellcode in order ...
JShell is a Java read-eval-print loop which was first introduced in the JDK 9. [1] It is tracked by JEP 222 jshell: The Java Shell (Read-Eval-Print Loop). [2] One reason why JShell was proposed for Java 9 is the lack of a standard interactive environment for the language; the de facto library to use a Java REPL was often BeanShell, which has been dormant since 2003, and arbitrarily diverged ...
