Canada cyber centre alert - government DDoS attacks

Source: cyber.gc.ca
Release Date: 15 Sept 2023


Since 13 September 2023, the Canadian Cyber Centre has been aware and responding to reports of several distributed denial of service (DDoS ) campaigns targeting multiple levels within the Government of Canada, as well as the financial and transportation sectors.


An Alert was published to raise awareness of these campaigns, to highlight the potential impact to government services and to provide guidance for organizations who may be targeted by malicious activity. Open-source reporting links some of this activity to Russian state-sponsored cyber threat actors whose tactics, techniques and procedures have been extensively documented .,


In July 2022, the Canadian Cyber Centre assessed that Russian state-sponsored cyber threat actors would almost certainly continue to perform actions in support of the Russian military's strategic and tactical objectives in Ukraine.


On February 24, 2023, the Canadian Cyber Centre reported on similar activity involving DDoS campaigns towards Ukraine-aligned nations.


Open-source reporting indicates that the actors leverage denial of service tools to harass organizations. This is accomplished through a collection of systems operating as a botnet that degrades a targeted web server's ability to provide services. This degradation is then publicized by the actors. In most cases, this nuisance activity can be managed by on-premises solutions; however, assistance from third party DDoS solutions should be considered to prevent significant and focused malicious activity. Websites will commonly return to a normal state of operation once the actors have stopped the malicious activity.
