Breaches were discovered at both DNS Belgium and Dutch registrar SIDN on Tuesday, July 9, 2013 (h/t Softpedia).

According to a statement on SIDN's Web site, malware was found on several SIDN Web sites on July 9. "In order to prevent abuse, SIDN immediately took a number of precautionary measures: the DRS web application was shut down and zone file publication was temporarily suspended," the statement reads. "As a result of our precautionary action, some areas of the website that registrars use to download registrarship-related data have been unavailable since Tuesday evening."

The company says the attack appears to have been launched via a SQL injection on the Web site 25jaarvan.nl.

A statement at DNS.be reports that a defacement was discovered on the company's Web site on July 9. "We immediately deleted the deface files and we took the necessary precautions to block further malicious access to the website," the statement reads. "We then performed a complete reinstall of the website. The DNS.be website does not grant access to confidential data or the registration platform."
