Yes! DDoS attacks are illegal in most countries around the world. It is both illegal to launch a DDoS attack and to hire a hacker to do this for you. Unfortunately, it’s very easy for even an unskilled hacker to go on the dark web and purchase the software needed to launch a DDoS attack
Those found guilty of this crime could face a prison sentence of up to 10 years in the US. The United Kingdom classifies DDoS attacks as a cybercrime under the Computer Misuse Act 1990. In Europe, large, multinational operations have been orchestrated by Europol to bring those responsible to justice.
