Cybersecurity best practices and DDoS defence strategies
Cyberspace was once envisioned as a global village free from geopolitical strife, but this idea is now far from reality. In fact, the online realm has its own trenches and barbed wires constructed from ones and zeros, rather than wood and steel. Moreover, cyberspace is often a reflection of real-world tensions. In this blog post, we will delve into the complex world of cyber warfare, a particularly relevant topic given the ongoing Russian invasion of Ukraine.
Cyber warfare is a broad term that encompasses a range of activities, from digitally supported military operations against nation-states to political hacktivism that promotes certain agendas, raises awareness, or even seeks to topple governments. Hacking, hacktivism, espionage, disinformation, propaganda, social media campaigns, and other forms of cybercrime are all part of this umbrella term. The primary objective of cyber warfare is to inflict significant damage on a target, either by disrupting their online systems, conducting espionage, or stealing sensitive data that can be used against adversaries.
Cyberattacks often have real-world consequences. For instance, the Colonial Pipeline disruption, which occurred in May 2021, is a prime example. The pipeline, which supplies nearly half of the fuel consumed on the East Coast of the United States, was shut down for several days following a ransomware attack. The attack resulted in widespread fuel shortages and panic buying in several states, leading to long queues at gas stations and higher prices. The disruption had a ripple effect throughout the economy, with airlines and trucking companies forced to adjust their operations due to the shortage of fuel.
Hospitals and other healthcare facilities have also been targeted by cyberattacks, which can have life-threatening consequences. In some cases, hackers have gained access to medical devices and systems, causing disruptions in patient care and even fatalities. For example, in 2017, a ransomware attack on hospitals in the United Kingdom caused widespread chaos, with patients being turned away and operations cancelled. The attack also affected medical devices, such as MRI scanners, leading to long delays in patient treatment.
In addition to these examples, hackers have also disrupted the electrical grids of certain countries, causing power outages and other disruptions. In 2015, a cyberattack on the Ukrainian power grid caused widespread blackouts, leaving hundreds of thousands of people without electricity. The attack was sophisticated and highly coordinated, with hackers gaining access to the grid's control systems, manipulating them to shut down power stations and substations. As a result, the outage lasted for several hours, affecting critical services such as hospitals, schools, and businesses across the country.
Cyber warfare is also employed for political and social activism, and often goes hand in hand with conventional warfare or, in some cases, precedes it. This is exemplified by the ongoing Russian invasion of Ukraine. Even before Russian troops crossed the border, Ukraine experienced relentless assaults from hackers that took down governmental websites and flooded the country with new forms of malware, aimed at limiting the country’s ability to defend itself by feeding false information into social media to influence public opinion and reduce Ukrainians’ access to information. However, members of the hacktivist collective Anonymous, alongside Ukraine's cyber army retaliated, initiating a cyber war against Russia. After the invasion began, Russian media, which played a key role in the Kremlin propaganda apparatus, became their primary target. The battle continues on social media, with individuals countering propaganda in comment sections by providing counterarguments against trolls, provocateurs, and those misled by Russian media. As demonstrated, cyber warfare and real-world tensions between nation-states are often inextricably linked.
The consequences of cyberattacks on critical infrastructure are not limited to economic disruption and loss of life, they can also have long-term effects on national security and geopolitical stability. In the case of the Ukrainian power grid attack, for instance, the incident was attributed to Russian state-sponsored hackers, raising concerns about the use of cyber warfare as a tool of statecraft. Similarly, the ongoing Russian attack on Ukraine, which has involved cyber operations as well as conventional military actions, has raised questions about the role of cyber warfare in modern conflict.
In conclusion, the real-world consequences of cyberattacks are significant and far-reaching, affecting not only the targeted organization or country but also the broader society and economy. As such, a comprehensive DDoS incident response plan, coupled with an automated, modern, always-on DDoS mitigation system, has become a critical priority for governments, businesses, and individuals alike, particularly during times of international crisis or conflict.
