Hi,
Could anyone direct me to any sites that have any info on unix attcks or hacks in the last 5 years. This is needed for an assignment. All help would be greatly appreciated.

wwconfig(8) System Manager's Manual wwconfig(8)NAME
wwconfig - Configures tty features for Asian countries
SYNOPSIS
/usr/sbin/wwconfig [-a | -A | -d | -D] [-n | -N] [-s | -l]
OPTIONS
Merges worldwide support tty features into the system configuration file by prompting you to choose among options. Merges all worldwide
support tty features into the system configuration file. When you specify the -A option, you are not prompted to choose among options.
Deletes from the system configuration file only the worldwide support tty features that have been de-installed. Deletes all worldwide sup-
port tty features from the system configuration file. Dynamically links the Asian terminal driver into the kernel at boot time. (A kernel
rebuild is not required when the driver is dynamically linked.) The -l option also specifies use of the STREAMS terminal driver with the
pseudo terminal device used for network login. (If past use of wwconfig caused the BSD terminal driver to be used for this pseudo terminal
device, then the -l option will cause a fallback to the STREAMS terminal driver.)
The -l option is the default if the Asian terminal driver is not already installed. Otherwise, the default is for wwconfig to use
the linking method that was used for the currently installed driver. Does not rebuild the kernel. Rebuilds the network kernel for
DMS support. Statically links the Asian terminal driver into the kernel image. A kernel rebuild and replacement must then be done
before the Asian terminal driver is available for use. This option also forces use of the BSD terminal driver with the pseudo termi-
nal device used for network login.
DESCRIPTION
The wwconfig procedure integrates worldwide support tty features into the running kernel or removes those features from the kernel. Cur-
rently, you can configure a generic Asian multibyte tty driver (atty) and a single-byte Thai tty driver (ttty) into the running kernel.
The Asian tty driver has several optional features that you can choose to set up. Depending on which subsets are installed, the wwconfig
procedure may ask questions on the following topics: The UTX daemons to start and connect to the atty driver through the utxd daemon.
You can choose to start the following UTX daemons: To support the Kana-Kanji conversion method for Japanese To support on-demand
loading of user-defined characters To support the phrase input method for Chinese
Refer to kkcd(8), odld(8), and simd(8) for more information about these daemons. For Chinese, whether BIG-5, Telecode (Telex), or
both codesets are supported as valid terminal codes and whether codeset conversion support is included for Simplified and Tradi-
tional Chinese. How many UTX pseudo devices to create Whether the Thai tty driver, if installed, is set up in addition to the Asian
tty driver
As is true for kernel layered products, the wwconfig command uses the kreg utility to register the worldwide support tty features. After
the kernel configuration process completes, config.file in the /usr/i18n/sys/BINARY directory is updated to reflect the tty features that
you selected. The current system configuration file is also updated, if necessary.
Because the tty features are registered through the kreg utility, you can use the doconfig command to build a new kernel without affecting
the current setup for worldwide support tty features.
