In the last year, geopolitical tension has led to an uptick of reported cybercrime events fueled by hacktivist groups. The US Cybersecurity and Infrastructure Security Agency (CISA) published an advisory to warn organizations about these attacks and teamed with the FBI on a distributed denial-of-service (DDoS) response strategy guide. KillNet, a group that the US Department of Health and Human Services (DHHS) has called pro-Russia hacktivists, has been launching waves of attacks against western countries, targeting governments and companies with focus on the healthcare sector. DHHS published an analyst note on KillNet’s threat to the health sector, mentioning that the group compromised a US healthcare organization that supports members of the US military.
KillNet uses DDoS as its main protest tool. DDoS attacks are a relatively easy and low-cost method of disrupting online services and websites and can be a powerful way to draw attention, making them a popular choice among hacktivist groups. In addition, DDoS attacks can be launched anonymously, which could make it difficult for authorities to track down perpetrators.
