[**WhiteIntel**](https://whiteintel.io) is a **dark-web** fueled search engine that offers **free** functionalities to check if a company or its customers have been **compromised** by **stealer malwares**.
Their primary goal of WhiteIntel is to combat account takeovers and ransomware attacks resulting from information-stealing malware.
You can check their website and try their engine for **free** at:
{% embed url="https://whiteintel.io" %}

If you have pcap with data being **exfiltrated by DNSCat** (without using encryption), you can find the exfiltrated content.
You only need to know that the **first 9 bytes** are not real data but are related to the **C\&C communication**:
```python
from scapy.all import rdpcap, DNSQR, DNSRR
import struct
f = ""
last = ""
for p in rdpcap('ch21.pcap'):
if p.haslayer(DNSQR) and not p.haslayer(DNSRR):
qry = p[DNSQR].qname.replace(".jz-n-bs.local.","").strip().split(".")
qry = ''.join(_.decode('hex') for _ in qry)[9:]
if last != qry:
print(qry)
f += qry
last = qry
#print(f)
```
For more information: [https://github.com/jrmdev/ctf-writeups/tree/master/bsidessf-2017/dnscap](https://github.com/jrmdev/ctf-writeups/tree/master/bsidessf-2017/dnscap)\
[https://github.com/iagox86/dnscat2/blob/master/doc/protocol.md](https://github.com/iagox86/dnscat2/blob/master/doc/protocol.md)
There is a script that works with Python3: [https://github.com/josemlwdf/DNScat-Decoder](https://github.com/josemlwdf/DNScat-Decoder)
```bash
python3 dnscat_decoder.py sample.pcap bad_domain
```

## Improve your Wireshark skills
### Tutorials
The following tutorials are amazing to learn some cool basic tricks:
* [https://unit42.paloaltonetworks.com/unit42-customizing-wireshark-changing-column-display/](https://unit42.paloaltonetworks.com/unit42-customizing-wireshark-changing-column-display/)
* [https://unit42.paloaltonetworks.com/using-wireshark-display-filter-expressions/](https://unit42.paloaltonetworks.com/using-wireshark-display-filter-expressions/)
* [https://unit42.paloaltonetworks.com/using-wireshark-identifying-hosts-and-users/](https://unit42.paloaltonetworks.com/using-wireshark-identifying-hosts-and-users/)
* [https://unit42.paloaltonetworks.com/using-wireshark-exporting-objects-from-a-pcap/](https://unit42.paloaltonetworks.com/using-wireshark-exporting-objects-from-a-pcap/)
### Analysed Information
**Expert Information**
Clicking on _**Analyze** --> **Expert Information**_ you will have an **overview** of what is happening in the packets **analyzed**:
![](<../../../.gitbook/assets/image (570).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.
![](<../../../.gitbook/assets/image (571).png>)
**Protocol Hierarchy**
Under _**Statistics --> Protocol Hierarchy**_ you can find the **protocols** **involved** in the communication and data about them.
![](<../../../.gitbook/assets/image (572).png>)
**Conversations**
Under _**Statistics --> Conversations**_ you can find a **summary of the conversations** in the communication and data about them.
![](<../../../.gitbook/assets/image (573).png>)
**Endpoints**
Under _**Statistics --> Endpoints**_ you can find a **summary of the endpoints** in the communication and data about each of them.
![](<../../../.gitbook/assets/image (575).png>)
**DNS info**
Under _**Statistics --> DNS**_ you can find statistics about the DNS request captured.
![](<../../../.gitbook/assets/image (577).png>)
**I/O Graph**
Under _**Statistics --> I/O Graph**_ you can find a **graph of the communication.**
![](<../../../.gitbook/assets/image (574).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.
### 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:
![](<../../../.gitbook/assets/image (403).png>)
And a column that add the Server name from an initiating HTTPS connection (**ssl.handshake.type == 1**):
![](<../../../.gitbook/assets/image (408) (1).png>)
## Identifying local hostnames
### From DHCP
In current Wireshark instead of `bootp` you need to search for `DHCP`
![](<../../../.gitbook/assets/image (404).png>)
### From NBNS
![](<../../../.gitbook/assets/image (405).png>)
## Decrypting TLS
### Decrypting https traffic with server private key
_edit>preference>protocol>ssl>_
![](<../../../.gitbook/assets/image (98).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
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:
![](<../../../.gitbook/assets/image (99).png>)
To import this in wireshark go to \_edit > preference > protocol > ssl > and import it in (Pre)-Master-Secret log filename:
![](<../../../.gitbook/assets/image (100).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()
```
