Zero-click attacks: everything you need to know

Zero-click attacks can be traced back to the early days of cyber-attacks and whilst we have seen a steady uptick in zero-click attacks over the last few years, 2024 is set to be a year of proliferation for this devastating cyber-attack.

As organisations and individuals become digital-first and device-dependant, understanding, and mitigating the risks associated with these attacks is crucial.

In this comprehensive guide, we will delve into the definition, intricacies, vulnerabilities, real-world incidents, and effective mitigation strategies for zero-click attacks.

Definition and overview of zero-click attacks

Zero-click attacks are a formidable threat that can infiltrate systems without requiring any direct interaction from users. Unlike traditional cyber threats that depend on user-triggered actions, zero-click attacks leverage intricate vulnerabilities in software, networks, and protocols to stealthily breach digital defences.

As zero-click attacks eliminate the need for any affirmative user engagement, they become particularly insidious. The absence of any sort of user interaction in these attacks makes them highly deceptive, as victims remain unaware of the compromise, allowing threat actors to operate covertly and persistently within targeted environments. If you consider that cyber threats are designed to go under the radar for as long as possible (average cyber breach in the UK takes up to 260 days to detect), zero-click attacks aim to take this to the next level.

Often, to run a zero-click attack, a threat actor needs to meticulously craft a malicious payload whilst also understanding the intricacies of the target system, in order to evade detection mechanisms. The payload is then delivered through a variety of means, including weaponised documents, malicious links, or network-based vectors, each carefully selected to exploit the identified vulnerabilities.

Zero-click attacks represent a paradigm shift in cyber security, demanding heightened awareness and proactive defences. It is also evident that a comprehensive understanding of these attacks is essential for individuals, organisations, and cyber security professionals alike.

What does a zero-click attack look like?

To comprehend the anatomy of zero-day attacks, we must explore the various phases involved, from vulnerability exploitation to the discreet achievement of malicious objectives.

1. Identify vulnerability: Zero-click attacks rely on a diverse array of vulnerabilities that permeate the digital landscape. These vulnerabilities include things like unsecured network protocols, operating system flaws mobile OS-specific weaknesses and more that we will discuss and explain further down this guide. The attackers meticulously exploit these vulnerabilities to pave the way for surreptitious entry into the targeted systems.
2. Forming a plan of attack: At the heart of a zero-click attack lies a meticulously crafted payload, a digital weapon tailored to navigate the intricacies of the target system. Cybercriminals invest time and expertise to develop code that not only exploits the identified vulnerabilities but also evades detection by security measures.
3. Delivery mechanism: Zero-click attacks employ diverse delivery mechanisms to infiltrate systems. This can range from the deployment of weaponised documents and .......
