#362: How Nmap really works // And how to catch it // Stealth scan vs TCP scan // Wireshark analysis
Chris and I go deep into what Nmap is actually sending onto the network and how you can find those dodgy packets! We then get into a real world Wireshark discussion on how to find stuff in a sea of packets. // MENU // 0:00 ▶️ Welcome 2:15 ▶️ What is Nmap? 3:54 ▶️ TCP SYN and TCP connect scans 6:55 ▶️ Wireshark IP Filter 7:42 ▶️ Wireshark TCP Port Filter 7:57 ▶️ Stealth Scan 09:37 ▶️ Why it's called a stealth scan 11:02 ▶️ Connect() scan 11:50 ▶️ How to identify potential Nmap scans in Wireshark 15:05 ▶️ Wireshark filters to find potential stealth scans 19:08 ▶️ Nmap Port Flag 20:16 ▶️ What makes a TCP connect scan different 22:47 ▶️ What is TCP Conversation Completeness 26:16 ▶️ Wireshark filter to identify potential TCP connect scans 29:06 ▶️ Are devices good enough today to capture huge amounts of data? 31:09 ▶️ Network Traffic Monitoring Device 32:55 ▶️ How to find specific data in huge files 42:27 ▶️ Final tips for beginners in cybersecurity 43:27 ▶️ Topics for future videos // Wireshark pcap file // https://davidbombal.wiki/nmapstealth // Wireshark documentation // https://www.wireshark.org/docs/wsug_h... // MY STUFF // https://www.amazon.com/shop/davidbombal // SOCIAL // Discord: https://discord.com/invite/usKSyzb Twitter: https://www.twitter.com/davidbombal Instagram: https://www.instagram.com/davidbombal LinkedIn: https://www.linkedin.com/in/davidbombal Facebook: https://www.facebook.com/davidbombal.co TikTok: http://tiktok.com/@davidbombal YouTube: https://www.youtube.com/davidbombal //CHRIS GREER // LinkedIn: https://www.linkedin.com/in/cgreer/ YouTube: https://www.youtube.com/c/ChrisGreer Twitter: https://twitter.com/packetpioneer Pluralsight: TCP Analysis Course: https://davidbombal.wiki/tcpwireshark // SPONSORS // Interested in sponsoring my videos?
