## Tool introduction
|
||||
## What is RedGuard
|
||||
|
||||
RedGuard is a derivative work of the C2 facility pre-flow control technology. It has a lighter design, efficient flow interaction, and reliable compatibility with go language development. The core problem it solves is also in the face of increasingly complex red and blue attack and defense drills, giving the attack team a better C2 infrastructure concealment scheme, giving the interactive traffic of the C2 facility a flow control function, and intercepting those "malicious" analysis traffic, and better complete the entire attack mission.

||||
RedGuard, a derivative tool based on command and control (C2) front flow control technology, has a lighter design, efficient traffic interaction, and reliable compatibility with development in the go programming language.As cyber attacks are constantly evolving , the red and blue team exercises become progressively more complex, RedGuard is designed to provide a better C2 channel hiding solution for the red team, that provides the flow control for the C2 channel, blocks the "malicious" analysis traffic, and better completes the entire attack task.
|
||||
|
||||
RedGuard is a C2 facility pre-flow control tool that can avoid Blue Team, AVS, EDR, Cyberspace Search Engine checks.

## Application scenarios
|
||||
## When is RedGuard Used?

|
||||
- Built-in blacklist of IPV4 addresses for a large number of devices, honeypots, and cloud sandboxes associated with security vendors to automatically intercept redirection request traffic
|
||||

RedGuard 23.05.13 has updated the trojan sample fingerprint recognition function, which is based on customizing the HTTP Header field of the Malleable Profile as the fingerprint “**sample salt value**” for uniquely identifying the same **C2 listener**/Header Host. In addition, the trojan sample fingerprint generated by combining other relevant request fields can be used to detect the custom sample liveliness. According to the attacker’s task requirements, the trojan sample fingerprint recognition function can perform “**offline operation**” on the samples you want to disable, to better evade malicious traffic analysis of the sample communication and the staged sample PAYLOAD attack payload acquisition analysis, and provide more personalized stealth measures for the attacker.
|
||||
|
||||
As shown in the figure below, when our interception rule is set to DROP, the spatial mapping system probe will probe the / directory of our reverse proxy port several times. In theory, the request packet sent by mapping is faked as normal traffic. Show. But after several attempts, because the characteristics of the request packet do not meet the release requirements of RedGuard, they are all responded by Close HTTP. The final effect displayed on the surveying and mapping platform is that the reverse proxy port is not open.
|
||||
For different C2 listeners, we can give different aliases to the Malleable Profile configurations, customize the field names and values of related headers as the sample salt value, and use it as one of the distinctions between different samples. The following code is for illustration purposes, and in actual attack and defense scenarios we can use more realistic HTTP request packet fields as the basis for judgment.
|
||||
|
||||
```bash
|
||||
http-get "listen2" {
|
||||
set uri "/image.gif";
|
||||
client {
|
||||
header "Accept-Finger" "866e5289337ab033f89bc57c5274c7ca"; //Custom HTTP Header and Value
|
||||
metadata {
|
||||
print
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**HTTP traffic**
|
||||
|
||||
|
||||
|
||||
As shown in the figure, we use the above sample Salt value and Host field as the basis for fingerprint generation. Here we know:
|
||||
|
||||
- **Salt Value：866e5289337ab033f89bc57c5274c7ca**
|
||||
- **Host ：redguard.com**
|
||||
|
||||
According to splicing the above values, the sample fingerprint is obtained as follows:
|
||||
|
||||
```bash
|
||||
22e6db08c5ef1889d64103a290ac145c
|
||||
```
|
||||
|
||||
Now that we know the above sample fingerprint, we can set the custom Header field and sample fingerprint in the RedGuard configuration file for malicious traffic interception. It is worth noting that we can extend multiple sample fingerprints, separated by commas, and the FieldName needs to be consistent with the Header field name configured in the Malleable Profile
|
||||
|
||||
|
||||
|
||||
Because RedGuard’s configuration file is a hot configuration, we don’t need to restart RedGuard to intercept the samples we want to disable. When we want the sample to be reactivated, we just need to delete the relevant sample fingerprint from the RedGuard configuration file.
|
||||

||||

The traffic shown in the figure below means that when the interception rule is set to Redirect, we will find that when the mapping probe receives a response, it will continue to scan our directory. UserAgent is random, which seems to be in line with normal traffic requests, but both successfully blocked.

## Domain fronting

|

RedGuard supports Domain fronting. In my opinion, there are two forms of presentation. One is to use the traditional Domain fronting method, which can be achieved by setting the port of our reverse proxy in the site-wide acceleration back-to-source address. On the original basis, the function of traffic control is added to the domain fronting, and it can be redirected to the specified URL according to the setting we set to make it look more real. It should be noted that the RedGuard setting of the HTTPS HOST header must be consistent with the domain name of the site-wide acceleration.

RedGuard 22.08.03 updated the edge host conection settings - custom intranet host interaction domain name, and the edge host uses the domain front CDN node interaction.

It is important to note that the `OverrideRequestHost` setting must be set to `true`. This is due to a quirk in the way Metasploit handles incoming HTTP/S requests by default when generating configuration for staging payloads. By default, Metasploit uses the incoming request's `Host` header value (if present) for second-stage configuration instead of the `LHOST` parameter. Therefore, the build stage is configured to send requests directly to your hidden domain name because CloudFront passes your internal domain in the `Host` header of forwarded requests. This is clearly not what we are asking for. Using the `OverrideRequestHost` configuration value, we can force Metasploit to ignore the incoming `Host` header and instead use the `LHOST` configuration value pointing to the origin CloudFront domain.

## Sample FingerPrint
|
||||
|
||||
RedGuard 23.05.13已更新木马样本指纹识别功能，该功能基于对Malleable Profile自定义设置HTTP Header字段，作为该指纹“**样本Salt值**”为相同**C2监听器/**Header Host提供唯一辨识并结合其他相关请求字段生成木马样本指纹，用于自定义样本存活性。根据攻击方任务需求，针对希望失效的样本进行**“下线操作”**，更好的规避恶意研判流量的样本通联性关联及分阶段样本PAYLOAD攻击载荷获取分析，给予攻击方更加个性化的隐匿措施。
|
||||
|
||||
针对不同C2监听器，我们可以设置不同Malleable Profile配置别称并自定义相关header的字段名及值，作为样本Salt值并以此作为区分不同样本之间的辨识之一。下列代码是为了方便说明，而在实际攻防场景下我们可以给予更加贴合实际的HTTP请求包字段作为判断依据。
|
||||
|
||||
```bash
|
||||
http-get "listen2" {
|
||||
set uri "/image.gif";
|
||||
client {
|
||||
header "Accept-Finger" "866e5289337ab033f89bc57c5274c7ca"; //用户自定义字段名及值
|
||||
metadata {
|
||||
print
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**HTTP流量**
|
||||
|
||||
|
||||
|
||||
如图所示，我们根据上述样本Salt值及Host字段作为指纹生成依据，这里我们已知:
|
||||
|
||||
- **Salt值：866e5289337ab033f89bc57c5274c7ca**
|
||||
- **Host字段值：redguard.com**
|
||||
|
||||
这里根据对上述值进行拼接得到sample指纹为：
|
||||
|
||||
```bash
|
||||
22e6db08c5ef1889d64103a290ac145c
|
||||
```
|
||||
|
||||
目前已知上述样本指纹，现在我们在RedGuard配置文件中设置自定义的Header字段及样本指纹用于恶意流量拦截，值得注意的是我们可以拓展多个样本指纹，不同指纹之间以逗号分隔，FieldName需要和Malleable Profile中配置的Header字段名称达成一致。
|
||||
|
||||
|
||||
|
||||
因为RedGuard的配置文件为热配置，所以这里我们不需要重新启停RG即可实现针对希望失效的样本进行拦截，当我们希望该样本重新生效时，只需在RG配置文件中删除相关样本指纹即可实现。
