Here you can find a list of some popular methods used by Nightmare Stresser and description for those methods.
A CLDAP Reﬂection Attack is a UDP based Layer 4 attack that exploits the Connectionless Lightweight Directory Access Protocol (CLDAP), which is an efﬁcient alternative to LDAP queries over UDP. Where the Attacker sends an CLDAP request thousands of servers to generate a large amount of UDP traffic.
With a DNS attack, the attacker takes advantage of a DNS server that permits lookups and uses recursion to spread his attack to other DNS servers. This generate a large amount of UDP traffic.
UDP-BYPASS Is a Advanced method created to bypass the firewalls and ddos protection of servers to be able to flood protected servers.
SSYN Is a spoofed version of SYN, In a SYN flood attack, the attacker sends repeated SYN packets to the port on the targeted server, using a fake IP address. This causes the server to go offline.
TCP-AMP is a tcp AMP method where the attacker sends requests to vulnerable servers to create large amount of TCP traffic.
TCP-BYPASS Is a Advanced TCP method created to bypass the firewalls and ddos protection of servers to be able to flood protected servers.
HTTP BURST is a unique method that bypasses some simple firewalls and is able to generate lots of requests to take websites offline.
XEMULATOR Is a advanced layer 7 flood method that emulates the chromium browser and is able to bypass advanced protections like the catcha aka "im not a robot" protection but often takes about 60-120 seconds to take effect.
SOCKET method is able to generate lots of requests to take websites offline.
