The website of the port of Rotterdam was targeted in a cyberattack blamed on Russia-aligned hackers last week.

Several Dutch ports including Amsterdam and Groningen also faced distributed-denial-of-service attacks, known as DDoS, according to port authorities. The port of Rotterdam received information from the Dutch National Cyber Security Center that pro-Russian groups were responsible for the attack, a spokesperson said by phone. 

Dutch news outlet RTL, which first reported the incidents, said a hacker group it called “NoName057(16)” claimed the attacks were a response to the Netherlands’s plans to buy Swiss tanks for Ukraine.
