“My class at home”: doubts about an attack from abroad – France

Several denial of service attacks, saturating Cned’s “My class at home” servers, which would have resulted in connection problems Tuesday morning between 8 am and 10 am. By pointing to computer attacks “apparently coming from abroad”, to explain a part of the many dysfunctions observed on this first day of remote school, the Minister of National Education, Jean-Michel Blanquer, was immediately accused of wanting to hide the lack of preparation of his services.

“If this attack comes from a foreign country, its effect is not monstrous”, the traffic having been quickly restored, remarks Loïc Guézo, the general secretary of Clusif, an association of security professionals.

In the 2000s

Inexpensive, denial of service attacks consist of creating as much traffic as possible to a website to block its operation. After experiencing their heyday in the 2000s, this type of attack has since taken a back seat in the threat landscape. Indeed, if they are simple to implement, they are also easy to counter, a point which feeds the trial in unpreparedness made to the National Education. Result: they are neglected by most cybercriminals, who now prefer to steal data in an attempt to extort ransoms.

On the contrary, the “hacktivists” have seized on this technique. Thus, in January 2020, the French justice had lifted the veil on a cyberattack which had affected four years earlier the sites of the Senate, the National Assembly, the ministries of Justice and Defense, or the Socialist Party. Kevin, a young Frenchman living in Belgium, had written a small computer program that automatically launched millions of connections to these institutional sites. Sentenced to six months in prison, the creator of the AnonymousArmyFr twitter account was challenging the Labor law, the state of emergency and government policy.
