Could an attacker just simply grab a SNMPv3 MD5 or SHA1 hash from a packet capture and brute force the plaintext password?. Would the use of SHA1 be more secure than MD5 for SNMPv3 user authentication?. As SNMPv3 only allows the use of MD5 or SHA1 for user authentication, this raised some questions: However, the alternative hash algorithm, SHA1, is also depreciated. The use of MD5 is always a red flag as it has long been depreciated in other implementations. So the idea is to get all the traffic on a secured WPA2 access point, if you know everything and you even have access to the router.While reviewing a client's Simple Network Management Protocol version 3 (SNMPv3) implementation, it was observed by Applied Risk consultants that they were using the MD5 hash algorithm option for user authentication. How can I monitor all the traffic on the network (decrypted, and from all IPs) if I have the password, and I can even get a 4 Way handshake if it's needed.Įdit -> Preferences -> Protocols -> IEEE 802.11 -> New -> wpa-psk and in the Key box: "AP:password" but I get an Invalid key format error. If I set it for my real wireless card, I get traffic but only from my IP address. I've started wireshark with mon0, and there were only encrypted wireless 802.11 packets. I've first set my wireless network in monitor mode (I am using Manjaro linux, and I've set it into monitor mode with airmon-ng), and I've tried to see the traffic. 
I have 3 laptops in here, and I want to capture all the traffic from the router with Wireshark. I have a wireless network, with a WPA2 password. Ok, so I want to do some tests on my network.
