In recent news, it has been reported that two Russia-sympathetic hacktivist groups, Killnet and AnonymousSudan, have allegedly launched a series of distributed denial-of-service (DDoS) attacks on multiple Australian organisations, according to Cloudflare.
These attacks have caused significant disruptions and downtime for the targeted entities, including government agencies and private sector companies. DDoS attacks are a type of cyber attack where a network or website is flooded with traffic from multiple sources, overwhelming the server and causing it to crash or become unavailable.
Individuals or groups can carry out these attacks and can be motivated by various factors such as political or ideological reasons, financial gain, or to cause chaos.
“Killnet is not a traditional hacking group: it does not have a membership, it does not have tools or infrastructure, and it does not operate for financial gain,” said Cloudflare.
Killnet was reportedly formed in response to the IT Army of Ukraine, a similar group that supported the Ukrainian military in their fight against pro-Russian separatists. The tactics used by Killnet are identical to those employed by the IT Army of Ukraine.
Additionally, AnonymousSudan is a nontraditional hacking group comprising Sudanese “hacktivists” owned for their anti-government stance and attacks on government and corporate websites. The group has been linked to several cyberattacks in the past, including attacks on government websites in Sudan and other African countries.
“Attackers, including from these groups, are becoming more audacious in the size and scale of the organisations they are targeting. What this means for businesses, especially those with limited cyber resources, is an increasing threat level against vulnerable networks,” Cloudfare added.
According to Cloudflare, the attacks were carried out using a combination of tactics, including amplification attacks that exploited vulnerabilities in the domain name system (DNS) and brute force attacks that used bots to flood the targets with traffic. The group behind the attacks has not yet been identified. Still, Cloudflare claims that the tactics used suggest the involvement of Killnet and AnonymousSudan, two hacktivist groups known for their pro-Russian stance.
The Australian government has yet to comment on the attacks. Still, cybersecurity experts have warned that this incident highlights the increasing threat of hacktivist groups and the need for organisations to protect their networks and infrastructure proactively. It remains to be seen what impact these attacks will have on the affected organisations, but it is clear that cyber threats are a growing concern for governments and businesses worldwide.
