## 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.
.png>)
**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.
.png>)
**Endpoints**
Under _**Statistics --> Endpoints**_ you can find a **summary of the endpoints** in the communication and data about each of them.
.png>)
**DNS info**
Under _**Statistics --> DNS**_ you can find statistics about the DNS request captured.
.png>)
**I/O Graph**
Under _**Statistics --> I/O Graph**_ you can find a **graph of the communication.**
.png>)
### 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`
.png>)
### 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()
```
