The attack targeted Rossel media group, affecting multiple of its web properties. Reportedly, a ransomware attack exploited a firewall failure, leading to instability in website access.
While the print edition remained unaffected, the incident highlighted the vulnerabilities of digital news platforms, especially those with large audiences in the mobile news space. It underscored the need for media firms to strengthen web security to protect their content and audiences from disruptions.
3. Security Flaws in Postal Operator Bpost
In 2020, investigative reporting revealed multiple security and privacy weaknesses in Bpost, Belgium’s leading postal service. The flaws made parcel tracking and pickup details accessible inappropriately, constituting breaches of privacy protections and risking customer trust.
Bpost swiftly addressed the issue by tightening access controls, disallowing general parcel searches, and assuring clients about the security and timeliness of deliveries. This episode pointed to the challenges postal services face in modernizing operations while safeguarding customer data and privacy laws.
4. Cyberattack on the Belgian Defense Ministry via Log4Shell Vulnerability
In late 2021, the Belgian Defense Ministry became one of many global targets affected by the critical Log4Shell vulnerability found in widely used Java logging software. This security loophole enabled attackers, including advanced persistent threat (APT) groups associated with various nation-states, to infiltrate defense systems.
Without detailed disclosures about attack specifics, the Ministry confirmed that cybersecurity teams acted promptly to secure networks and vowed ongoing investment to prevent recurrence.
This incident underscored the persistent risk software supply chain vulnerabilities pose to national security infrastructures across nations.
5. Sea-Invest Port Operations Halted After Ransomware Attack
Sea-Invest, operating key bulk goods terminals in Belgium and internationally, was forced to temporarily cease operations following a ransomware attack—disrupting supply chains at affected ports.
The shutdown impacted unloading barges and created logistical challenges for clients dependent on the transit of goods.
This breach illustrated the critical importance of ports within global trade and the potential cascading effects that cyberattacks can have on economies and supply chains. It also mirrored similar attacks on large port facilities, such as the well-documented Maersk and Rotterdam incidents.
6. Cybercrime Exploiting Antwerp Port Security Data
The Federal Computer Crime Unit initiated investigations into organized cybercrime targeting Antwerp’s port operations. Hackers hacked into company networks and accessed sensitive container location and security information, facilitating cargo theft including narcotics smuggling.
The operation uniquely combined cyber intrusion with traditional criminal trafficking, demonstrating how cybercrime can intersect with other illicit activities to cause significant economic and security harm.
The case highlighted the necessity of stringent cybersecurity measures and inter-agency cooperation to safeguard critical infrastructure.
7. Coordinated Cyberattack on Belgian Parliament and Universities
Belnet, the national internet service provider heavily relied upon by public sector institutions, including universities and parliament, was victim to a massive distributed denial of service (DDoS) attack in 2022.
The attack temporarily severed internet access for over 200 public and private organizations, impacting essential services.
Although the attack did not result in data theft, it demonstrated how aggressively adversaries can disrupt institutional operations through targeted overload techniques.
The prompt crisis response by the service provider and the national cybersecurity center exemplified effective incident management.
8. Patient Data Encryption at Vivalia Healthcare Group
Belgium’s Vivalia hospital group faced a ransomware incident that encrypted approximately 400 gigabytes of sensitive patient and employee data, forcing a shift to manual record-keeping. The Lockbit ransomware group took responsibility, threatening to publish the stolen data if their demands were unmet.
