## 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**:
**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.
**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: \
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.
### Free pcap labs
**Practice with the free challenges of:** [**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:
And a column that add the Server name from an initiating HTTPS connection (**ssl.handshake.type == 1**):
## 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>*
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
Both Firefox and Chrome have the capability to log TLS session keys, which can be used with Wireshark to decrypt TLS traffic. This allows for in-depth analysis of secure communications. More details on how to perform this decryption can be found in a guide at [Red Flag Security](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:
To import this in wireshark go to \_edit > preference > protocol > ssl > and import it in (Pre)-Master-Secret log filename:
## 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()
```

# Agent Instructions: Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter:
```
GET https://angelica.gitbook.io/hacktricks/generic-methodologies-and-resources/basic-forensic-methodology/pcap-inspection/wireshark-tricks.md?ask=
```
The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
