0x4d31/fattFATT /fingerprintAllTheThings - pyshark पर आधारित एक स्क्रिप्ट जो pcap फ़ाइलों और लाइव नेटवर्क ट्रैफ़िक से नेटवर्क मेटाडेटा और फ़िंगरप्रिंट निकालने के लिए है।

सभी चीज़ों की फिंगरप्रिंट लें!
फिंगरप्रिंटिंग विधियों, नमूना उपयोग-मामलों और शोध परिणामों के बारे में अधिक जानकारी जल्द ही रिपॉजिटरी में जोड़ी जाएगी। बने रहें!
एक स्क्रिप्ट जो पैकेट कैप्चर फ़ाइलों (pcap) या लाइव नेटवर्क ट्रैफ़िक से नेटवर्क मेटाडेटा और फिंगरप्रिंट जैसे JA3 और HASSH निकालती है। मुख्य उपयोग-मामला हनीपॉट्स की निगरानी के लिए है, लेकिन आप इसका उपयोग नेटवर्क फोरेंसिक विश्लेषण जैसे अन्य उपयोग-मामलों के लिए भी कर सकते हैं। fatt Linux, macOS और Windows पर काम करता है।
ध्यान दें कि fatt pyshark (tshark के लिए एक पायथन रैपर) का उपयोग करता है और इसलिए प्रदर्शन बहुत अच्छा नहीं है! लेकिन यह कोई बड़ी समस्या नहीं है क्योंकि स्पष्ट रूप से यह कोई ऐसा उपकरण नहीं है जिसे आप उत्पादन में उपयोग करते हैं। आप अधिक गंभीर उपयोग-मामलों के लिए Bro/Zeek, Suricata या Netcap जैसे अन्य नेटवर्क विश्लेषण उपकरणों का उपयोग कर सकते हैं। Joy एक और बेहतरीन उपकरण है जिसका उपयोग आप नेटवर्क प्रवाह डेटा को कैप्चर और विश्लेषण करने के लिए कर सकते हैं।
इसके अलावा, मैं fatt के गो-आधारित संस्करण पर काम कर रहा हूँ जो तेज़ है, और आप इसकी लाइब्रेरीज़ का उपयोग अपने gopacket-आधारित टूल्स जैसे packetbeat में कर सकते हैं। मैंने इसके gQUIC लाइब्रेरी (QUICk) का प्रारंभिक संस्करण जारी किया है।
आपको पहले tshark स्थापित करना होगा। सुनिश्चित करें कि आपके पास संस्करण v2.9.0 या बाद का है। Tshark/Wireshark ने संस्करण v2.9.0 से 'ssl' का नाम बदलकर 'tls' कर दिया है, और fatt tshark के नए संस्करण पर आधारित है।
यदि आपके पास tshark का पुराना संस्करण (< v2.9.0) है, तो आप "old-tshark" शाखा से fatt स्क्रिप्ट का उपयोग कर सकते हैं।
cd fatt/
pip3 install pipenv
pipenv install
या यदि आप वर्चुअल वातावरण का उपयोग नहीं करना चाहते हैं तो बस pyshark स्थापित करें:
pip3 install pyshark==0.4.2.2
वर्चुअलएनवी सक्रिय करने के लिए, pipenv shell चलाएँ:
$ pipenv shell
Launching subshell in virtual environment…
bash-3.2$ . /Users/adel/.local/share/virtualenvs/fatt-ucJHMzzt/bin/activate
(fatt-ucJHMzzt) bash-3.2$ python3 fatt.py -h
वैकल्पिक रूप से, pipenv run के साथ वर्चुअलएनवी के अंदर कमांड चलाएँ:
$ pipenv run python3 fatt.py -h

इस बार हमें RDP ClientInfo संदेश दिखाई नहीं देता क्योंकि PoC TLS (मानक RDP सुरक्षा प्रोटोकॉल नहीं) का उपयोग करता है। इसलिए हम केवल Negotiation Request संदेश देख सकते हैं, लेकिन यदि आप पैकेट को TLS के रूप में डिकोड करते हैं, तो आप TLS clientHello और JA3 फिंगरप्रिंट देख सकते हैं। यहाँ बताया गया है कि आप किसी विशिष्ट पोर्ट को दूसरे प्रोटोकॉल के रूप में कैसे डिकोड कर सकते हैं:
