DDoS instruments like Stacheldraht even now use classic DoS attack methods centered on IP spoofing and amplification like smurf attacks and fraggle attacks (varieties of bandwidth consumption attacks). SYN floods (a source starvation attack) may additionally be utilized. More recent resources can use DNS servers for DoS applications.
