The attack was attributed to SN_BLACKMETA, a hacktivist group possibly linked to Sudan and operating out of Russia. This group has a history of targeting high-profile infrastructure and financial systems in various countries including Israel, Canada, Saudi Arabia, France, and the UAE. SN_BLACKMETA announced the campaign on its Telegram channel before the attack highlighting its intention and following through with the execution.

SN_BLACKMETA's activities reflect a methodical approach to cyber warfare leveraging sophisticated attack methods and maintaining a high public profile through frequent updates and validations of their actions on social media. Their operations suggest a potential collaboration with other hacktivist groups like Killnet and the use of services such as InfraShutdown, a premium DDoS-for-hire service promoted by Anonymous Sudan. This service is known for its powerful and disruptive capabilities, posing a significant threat to global infrastructures.

The researchers emphasize the importance of robust DDoS mitigation strategies to withstand such intense and prolonged attacks. Essential measures include high-fidelity intelligence on threat actors behavioral-based detection to distinguish legitimate from malicious traffic, real-time signature creation to defend against unknown threats, and a comprehensive emergency response plan. Hybrid DDoS protection combining on-premise and cloud solutions is also crucial to address high-volume attacks and prevent network saturation.

Organizations are urged to bolster their defenses against sophisticated DDoS attacks by regularly inspecting and patching their networks. Implementing advanced cybersecurity measures and maintaining preparedness against emerging threats like SN_BLACKMETA are critical to safeguarding critical infrastructure and ensuring operational resilience.

Impact
