What is zero-click malware? How do you fight it? 

In today’s digital landscape, cybersecurity threats continue to evolve. They pose significant risks to individuals and organisations alike. One such threat gaining prominence is zero-click malware. This insidious form of malware requires no user interaction. It can silently compromise devices and networks.  

One example of this type of attack happened due to a missed call. That’s right, the victim didn’t even have to answer. This infamous WhatsApp breach occurred in 2019, and a zero-day exploit enabled it. The missed call triggered a spyware injection into a resource in the device’s software.  

A more recent threat is a new zero-click hack targeting iOS users. This attack initiates when the user receives a message via iMessage. They don’t even need to interact with the message of the malicious code to execute. That code allows a total device takeover.  

Below, we will delve into what zero-click malware is. We’ll also explore effective strategies to combat this growing menace.  

Understanding zero-click malware  

Zero-click malware refers to malicious software that can do a specific thing. It can exploit vulnerabilities in an app or system with no interaction from the user. It is unlike traditional malware that requires users to click on a link or download a file.  

The dangers of zero-click malware  

Zero-click malware presents a significant threat. This is due to its stealthy nature and ability to bypass security measures. Once it infects a device, it can execute a range of malicious activities. 

These include:  

  • Data theft 
  • Remote control 
  • Cryptocurrency mining 
  • Spyware 
  • Ransomware 
  • Turning devices into botnets for launching attacks  

This type of malware can affect individuals, businesses, and even critical infrastructure. Attacks can lead to financial losses, data breaches, and reputational damage.  

Fighting zero-click malware  

To protect against zero-click malware, it is crucial to adopt two things. A proactive and multi-layered approach to cybersecurity. Here are some essential strategies to consider:  

Keep software up to date 

Regularly update software, including operating systems, applications, and security patches. This is vital in preventing zero-click malware attacks. Software updates often contain bug fixes and security enhancements.  

Put in place robust endpoint protection 

Deploying comprehensive endpoint protection solutions can help detect and block zero-click malware. Use advanced antivirus software, firewalls, and intrusion detection systems.  

Use behavioural analytics and AI  

Leverage advanced technologies like behavioural analytics and artificial intelligence (AI). These can help identify anomalous activities that may indicate zero-click malware.  

Conduct regular vulnerability assessments 

Perform routine vulnerability assessments and penetration testing. This can help identify weaknesses in systems and applications.  

Uninstall unneeded applications 

The more applications on a device, the more vulnerabilities it has. Many users download apps then rarely use them. Yet they remain on their device, vulnerable to an attack.  

Only download apps from official app stores  

Be careful where you download apps. You should only download from official app stores.
