Today, ten Dutch organizations, including different municipalities, are the target of DDOS attacks. Various media have reported about this today. No system burglary or data theft takes place in these types of attacks. DDOS attacks fit in with the expectation that the NCSC already sketched in the run-up to the NATO summit. The attacks are primarily aimed at public organizations that deal with or play a role around the NATO top.
What is a DDOS attack?
A Distributed Denial-of-Service-attack (DDOS attack) is aimed at overloading online services, servers or network equipment. This allows websites and other digital systems to become temporarily slow or unreachable for users. This can cause problems, such as not being able to log in, or do not have access to information or services. For organizations that depend on online accessibility, this can disrupt their services. With a DDOS attack no system burglary or data theft takes place. These attacks have no impact on the integrity or confidentiality of (personal) data.
Motif
It is not always possible to gain insight into the people behind a DDOS attack or their motivation. Several of the attacks that were carried out today have been claimed by the pro-Russian actor Noname057 (16) and also seem to have a pro-Russian ideological motif. The NCSC has been following Noname057 (16) for a long time, and the attacks fit within a well -known pattern. The expectation is that these attacks will occur more often during the NATO summit.
The NCSC continues to follow the situation
The National Cyber Security Center (NCSC) is investigating the attacks. The NCSC is in contact with national and international cooperation partners, monitors the situation and keeps insight into the activities of pro-Russian groups such as Name057 (16). Where possible, the NCSC informs organizations that are a (future) target to provide them with a suitable action perspective.
