Following the chilling announcement by cyber activist groups Killnet, Revil, and Anonymous Sudan, the global financial community is on high alert. Their alleged plans to orchestrate a massive cyberattack on the European banking system within the next 48 hours have stirred an atmosphere of uncertainty and concern. The groups' proclamation, "Nothing can save you... No money - no weapons - no Kyiv regime. No problem. This is not a DDoS attack, the games have ended," has prompted urgent inquiries into the viability and impact of such an unprecedented assault.

Such an attack, if realized, could severely disrupt European banking operations, potentially resulting in significant economic damage. However, it's important to evaluate the credibility of this threat and consider the broader context of escalating cyber activities.

In July 2021, the World Economic Forum (WEF) and its partners conducted Cyber Polygon, a global simulation of a 'cyber pandemic'. The simulation involved a large-scale cyber attack on a company's supply chain, an event that the WEF referred to as a 'cyber pandemic'. Given the scenario now posed by the aforementioned cyber activist groups, the findings of the Cyber Polygon exercise have taken on a new significance.

Cyberattacks are increasingly targeting infrastructure services. The recent high-profile attacks on the Colonial Pipeline in the US and the public health service in Ireland highlight this trend. As these infrastructures increasingly integrate with the Internet of Things (IoT), they create millions of new vulnerability points for hackers.

Cyber criminals have been particularly focused on the Operational Technology (OT) networks that manage our critical infrastructure. Services such as power grids, water treatment facilities, transport, and healthcare systems are increasingly at risk due to their integration with IoT systems. This creates an expanding frontier of risks that cyber criminals can exploit.

IoT devices and systems pose a significant security risk for critical infrastructure when they do not implement security best practices. The lack of standardization in cybersecurity practices across the supply chain, vulnerable security protocols and designs, obsolete and unsupported architecture, firmware and software, and an attack surface that increases with the number of connected devices, make these systems a prime target for hackers.

The rise of the "Mozi" botnet attack, which accounted for 90% of total IoT attacks in 2020, has been particularly concerning. This type of attack allows cybercriminals to control hundreds of thousands of connected devices, infecting more devices, and enabling control over entire networks.

If the threats made by Killnet, Revil, and Anonymous Sudan are credible, and they do indeed have the capability to carry out their alleged plans, the European banking system could face unprecedented disruption and loss. This scenario underscores the urgency for strengthened cybersecurity measures, robust response plans, and international cooperation to mitigate the impact of such attacks.

While we must approach this threat with due seriousness, it's also essential to understand that such public proclamations may serve as instruments of fear and manipulation. It is for cyber security experts, law enforcement agencies, and global banking systems to ascertain the credibility of this threat and respond accordingly.

The looming threat, however, cannot be denied. As the world continues to digitize, the risk of a 'cyber pandemic' becomes an ever more pressing concern. Businesses, governments, and individuals must all take part in the collective effort to fortify digital infrastructure, create robust cybersecurity protocols, and ensure the safety and stability of our interconnected world.
