Federal prosecutors had opened an investigation into the operation’s origins, the data that had been compromised, and whether or not a foreign state was involved. The assault, which was discovered in March, was carried out in 2019, according to Belgian experts. The Belnet network, which links higher education institutions, colleges, research centres, and government agencies, was brought down by another large-scale attack in early May. The attack on the interior ministry’s website, however, was not intended to trigger a website outage or demand a ransom. According to the experts cited by RTBF, it was “more subtle and well targeted, leading us to believe it was espionage.” “Urgent action was taken to avoid the attacker’s entry,” Maerens said, adding that server protection had been improved. The discovery of the attack was held under wraps so that the system’s weakness could not be exposed until it was patched.
