πŸ¦‘DNS SPECIAL UTILITIES :

Β» dnsgram (https://doc.powerdns.com/md/manpages/dnsgram.1/): dnsgram is a debugging tool for intermittent resolver failures. it takes one or more input PCAP files and generates statistics on 5 second segments allowing the study of intermittent resolver issues.

Β» dnsreplaY (https://doc.powerdns.com/md/manpages/dnsreplay.1/): Dnsreplay takes recorded questions and answers and replays them to the specified nameserver and reporting afterwards which percentage of answers matched, were worse or better. Then compares the answers and some other metrics with the actual ones with those found in the dumpfile.

Β» dnsscan (https://doc.powerdns.com/md/manpages/dnsscan.1/): dnsscan takes one or more INFILEs in PCAP format and generates a list of the number of queries per query type.

Β» dnsscope (https://doc.powerdns.com/md/manpages/dnsscope.1/): dnsscope takes an input PCAP and generates some simple statistics outputs these to console.

Β» dnswasher (https://doc.powerdns.com/md/manpages/dnswasher.1/): dnswasher takes an input file in PCAP format and writes out a PCAP file, while obfuscating end-user IP addresses. This is useful to share data with third parties while attempting to protect the privacy of your users.

πŸ¦‘Attack identification

There are two main methods for identifying traffic attacks:

1) Ping test: If the Ping timeout or severe packet loss is found, it may be attacked. If the server on the same switch is found to be inaccessible, it can basically be determined as a traffic attack. The premise of the test is that the ICMP protocol between the victim host and the server is not blocked by devices such as routers and firewalls;

2) Telnet test: Its distinguishing feature is that the remote terminal fails to connect to the server, and it is easy to judge relative traffic attacks and resource exhaustion attacks. If the website is suddenly very slow or inaccessible, but it can be pinged, it is likely to be attacked. On the Netstat-na command, a large number of SYN_RECEIVED, TIME_WAIT, FIN_WAIT_1 and other statuses were observed, and EASTBLISHED is rarely, which can be determined as a resource exhaustion attack. The characteristic is that the victim host cannot Ping or the packet loss is serious and the server on the same switch is pinged normally. The reason is that the attack caused the system kernel or application CPU utilization to reach 100% and failed to respond to the Ping command, but because there is still bandwidth, the host on the same switch can be pinged.
