FEATURES

Bring intellectual network traffic analysis into Cloud. Open pcap files online with our pcapng viewer.


View HTTP headers and data stream

Deep packet inspection allows you to dive into HTTP communications: requests, responses, services information and payloads, collect post data and analyze pcap content.

Wonder which HTTP sessions are established, which credentials are sent ? Which files are transferred? A-Packets network traffic analysis will done it for you with integrated pcap file viewer.

Analyze pcap file to investigate HTTP streams with in-built HTTP analyzer, view network traffic, rebuild client-server communications step by step.

Find devices on network

You can easily get pcap visualization to explore network devices map, all communications between devices and classify network nodes by their type through pcap analysis. Visualize TCP/UDP communications from pcap file with network graph.

Quick read pcap files to detect DNS, DHCP and LDAP servers and sniff DNS requests in pcap file.

Devices map displays network traffic like other pcap tools for DNS/HTTP/HTTPS/SMB/SSH/RDP and other protocols and allows explore individual protocol links between network nodes.

Gather WiFi Information

View wireless networks information extracted from pcap file: you can find Access Points and their SSIDs (network names), reveal previously-associated networks for client devices using probe requests.

You can also look into encrypted network and sniff multicast traffic trying to detect used network protocols and services.

In case of WPA/WPA2 handshakes will be found in analyzed pcap file you can view and download them as .hccapx file to try to recover password with Hashcat.

Extract files from pcap

Pcap reader allows locate and extract pictures, office documents and other file formats detected during analyzing of uploaded pcap file. You can quick preview found files in network traffic and download them.

Comprehensive pcap file analysis provide you with all information about files in HTTP stream.

SMB Sniffer

SMB and NetBIOS packets provide a lot of information in broadcast packets about LAN structure. You can extract from pcap file information like versions of installed OS, NetBIOS names, workstation/server roles, admin comments for nodes.

Another one interesting thing could be found in SMB is NTLMv2-SSP authentication between nodes. Upload pcap file and you can try to crack found hashes with appropriated tools.

DNS queries investigation

You can explore all name resolution protocols like classic DNS, mDNS (Multicast DNS) and NBNS (NetBIOS Name Service) to gather information about network structure and activity of running services.

Filters allow separate DNS traffic by type and analyze queried names, targert servers or multicast/broadcast addresses (in case of mDNS and NBNS).
