## Improve your Wireshark skills
|
|
|
|
### Tutorials
|
|
|
|
The following tutorials are amazing to learn some cool basic tricks:

|
|
|
|
### Analysed Information
|
|
|
|
**Expert Information**
|
|
|
|
Clicking on _**Analyze** --> **Expert Information**_ you will have an **overview** of what is happening in the packets **analyzed**:
|
|
|
|
.png>)
|
|
|
|
**Resolved Addresses**
|
|
|
|
Under _**Statistics --> Resolved Addresses**_ you can find several **information** that was "**resolved**" by wireshark like port/transport to protocol, MAC to the manufacturer, etc. It is interesting to know what is implicated in the communication.
|
|
|
|

|
|
|
|
**Protocol Hierarchy**
|
|
|
|
Under _**Statistics --> Protocol Hierarchy**_ you can find the **protocols** **involved** in the communication and data about them.
|
|
|
|
.png>)
|
|
|
|
**Conversations**
|
|
|
|
Under _**Statistics --> Conversations**_ you can find a **summary of the conversations** in the communication and data about them.
|
|
|
|

|
|
|
|
**Endpoints**
|
|
|
|
Under _**Statistics --> Endpoints**_ you can find a **summary of the endpoints** in the communication and data about each of them.
|
|
|
|

|
|
|
|
**DNS info**
|
|
|
|
Under _**Statistics --> DNS**_ you can find statistics about the DNS request captured.
|
|

|
|
|
|
**I/O Graph**
|
|
|
|
Under _**Statistics --> I/O Graph**_ you can find a **graph of the communication.**
|
|
|

|
|
|
|
### Filters
|
|
|
|
Here you can find wireshark filter depending on the protocol: [https://www.wireshark.org/docs/dfref/](https://www.wireshark.org/docs/dfref/)\
|
|
Other interesting filters:
|
|
|
|
* `(http.request or ssl.handshake.type == 1) and !(udp.port eq 1900)`
|
|
* HTTP and initial HTTPS traffic
|
|
* `(http.request or ssl.handshake.type == 1 or tcp.flags eq 0x0002) and !(udp.port eq 1900)`
|
|
* HTTP and initial HTTPS traffic + TCP SYN
|
|
* `(http.request or ssl.handshake.type == 1 or tcp.flags eq 0x0002 or dns) and !(udp.port eq 1900)`
|
|
* HTTP and initial HTTPS traffic + TCP SYN + DNS requests
|
|
|
|
### Search
|
|
|
|
If you want to **search** for **content** inside the **packets** of the sessions press _CTRL+f_. You can add new layers to the main information bar (No., Time, Source, etc.) by pressing the right button and then the edit column.
|
|
|
|
Practice: [https://www.malware-traffic-analysis.net/](https://www.malware-traffic-analysis.net)
|
|
|
|
## Identifying Domains
|
|
|
|
You can add a column that shows the Host HTTP header:
|
|
|
|
.png>)
|
|
|
|
And a column that add the Server name from an initiating HTTPS connection (**ssl.handshake.type == 1**):
|
|
|
|
 (1).png>)
|
|
|
|
## Identifying local hostnames
|
|
|
|
### From DHCP
|
|
|
|
In current Wireshark instead of `bootp` you need to search for `DHCP`
|
|
|
|

|
|
|
|
### From NBNS
|
|

|
|
|
|
## Decrypting TLS
|
|
|
|
### Decrypting https traffic with server private key
|
|
|
|
_edit>preference>protocol>ssl>_
|
|
|
|
.png>)
|
|
|
|
Press _Edit_ and add all the data of the server and the private key (_IP, Port, Protocol, Key file and password_)
|
|
|
|
### Decrypting https traffic with symmetric session keys
|
|
|
|
It turns out that Firefox and Chrome both support logging the symmetric session key used to encrypt TLS traffic to a file. You can then point Wireshark at said file and presto! decrypted TLS traffic. More in: [https://redflagsecurity.net/2019/03/10/decrypting-tls-wireshark/](https://redflagsecurity.net/2019/03/10/decrypting-tls-wireshark/)\
|
|
To detect this search inside the environment for to variable `SSLKEYLOGFILE`
|
|
|
|
A file of shared keys will look like this:
|
|
|
|
.png>)
|
|
|
|
To import this in wireshark go to \_edit > preference > protocol > ssl > and import it in (Pre)-Master-Secret log filename:
|
|
|
|
.png>)
|
|
|
|
## ADB communication
|
|
|
|
Extract an APK from an ADB communication where the APK was sent:
|
|
|
|
```python
|
|
from scapy.all import *
|
|
|
|
pcap = rdpcap("final2.pcapng")
|
|
|
|
def rm_data(data):
|
|
splitted = data.split(b"DATA")
|
|
if len(splitted) == 1:
|
|
return data
|
|
else:
|
|
return splitted[0]+splitted[1][4:]
|
|
|
|
all_bytes = b""
|
|
for pkt in pcap:
|
|
if Raw in pkt:
|
|
a = pkt[Raw]
|
|
if b"WRTE" == bytes(a)[:4]:
|
|
all_bytes += rm_data(bytes(a)[24:])
|
|
else:
|
|
all_bytes += rm_data(bytes(a))
|
|
print(all_bytes)
|
|
|
|
f = open('all_bytes.data', 'w+b')
|
|
f.write(all_bytes)
|
|
f.close()
|
|
```
