今天开始读《Python绝技:运用Python成为顶级黑客》一书,第一章用一个小例子来讲解Python的基本语法和语句。主要学习的内容有:1. 安装第三方库。2. 变量、字符串、列表、词典。3. 网络的编程。4. 条件选择语句和for循环。5. 异常处理。6. 函数。7. 文件输入/输出。8. sys模块和os模块。把最后的代码贴在这里,做个记录。
import socket import os import sys port = 21 banner = "FreeFloat FTP Server" portList = [21,22,80,110] portOpen = True services = {‘ftp‘:21, ‘ssh‘:22, ‘smtp‘:25, ‘http‘:80} def retBanner(ip,port): try: socket.setdefaulttimeout(2) s = socket.socket() s.connect((ip,port)) banner = s.recv(1024) return banner except: return def checkVulns(banner,filename): f = open(filename,‘r‘) for line in f.readlines(): if line.strip(‘\n‘) in banner: print ‘[+] Server is vulnerable: ‘ + banner.strip(‘\n‘) def main(): if len(sys.argv) == 2: filename = sys.argv[1] if not os.path.isfile(filename): print ‘[-] ‘ +filename + ‘ does not exist.‘ exit(0) if not os.access(filename, os.R_OK): print ‘[-] ‘ +filename + ‘ access denied.‘ exit(0) else: print ‘[-] Usage: ‘ + str(sys.argv[0]) + ‘ <vuln filename>‘ exit(0) portList = [21,22,25,80,110,443] for x in range(147,150): ip = ‘192.168.95.‘ + str(x) for port in portList: banner = retBanner(ip,port) if banner: print ‘[+] ‘ + ip + ‘: ‘ + banner checkVulns(banner, filename) if __name__ == ‘__main__‘: main()
