# [+] Summary:
#
# Using Inter-protocol Communication (IPC) the zombie browser will send commands to a listening POSIX shell bound on the target specified in the 'Target Address' input. The target address can be on the zombie's subnet which is potentially not directly accessible from the Internet.
#
# The command results are returned to the BeEF control panel.
#
# [+] Tested:
#
# o Working:
#   o Mozilla Firefox 6
#
# o Not Working:
#   o Mozilla Firefox 6 with the NoScript extension
#   o Internet Explorer 8+
#   o Chrome 13
#   o Opera 11
#   o Safari 5
#
# [+] Notes:
#
# o The bindshell is closed once the module has completed. This is necessary otherwise the /bin/sh process will hang. To avoid this issue:
#
#   o remove the last "& exit" portion of the JavaScript payload. Be aware that this will leave redundant /bin/sh processes running on the target system.

#
# o Internet Explorer is not supported as IE 8+ does not allow posting data to internal network addresses. Earlier versions of IE have not been tested.
#
# o Returning the shell command results is not supported in Chrome, Safari and Opera as JavaScript cannot be executed within the bindshell iframe. The shell commands are executed on the target shell however.

Guidelines for contributing
===========================
To report a security issue (segfault, buffer overflow, infinite loop, arbitrary
code execution etc) please send an e-mail to security@tcpdump.org, do not use
the bug tracker!
To report a non-security problem (failure to compile, failure to capture packets
properly, missing support for a network interface type or DLT) please check
first that it reproduces with the latest stable release of libpcap. If it does,
please check that the problem reproduces with the current git master branch of
libpcap. If it does (and it is not a security-related problem, otherwise see
above), please navigate to https://github.com/the-tcpdump-group/libpcap/issues
and check if the problem has already been reported. If it has not, please open
a new issue and provide the following details:
* libpcap version (e.g. from `tcpdump --version`)
* operating system name and version and any other details that may be relevant
  (`uname -a`, compiler name and version, CPU type etc.)
* `configure` or `cmake` flags if any were used
* statement of the problem
* steps to reproduce
Please note that if you know exactly how to solve the problem and the solution
would not be too intrusive, it would be best to contribute some development time
and open a pull request instead.
Still not sure how to do? Feel free to [subscribe](https://www.tcpdump.org/#mailing-lists)
to the mailing list tcpdump-workers@lists.tcpdump.org and ask!
