WhiteIntel
WhiteIntel 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:

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: 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 with the free challenges of: 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.
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:
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()
