Ransomware is an increasingly sophisticated threat that poses serious risks to businesses worldwide. There are different types of ransomware that do different things, from causing operational disruptions to significant financial loss, ransomware can lock down critical systems, leaving businesses unable to function. The key to combating this threat is not only understanding how ransomware works but also knowing ransomware preventions against attacks in the first place. In this guide, we’ll explore the impact of ransomware, its legal landscape, and practical steps businesses can take to safeguard their data and operations.

Denotation of a Ransomware Attack

What Is Ransomware?

Ransomware is a malicious software program designed to encrypt or block access to your business’s critical systems until a ransom is paid. In commercial settings, attackers often target valuable information, such as client data, financial records, or intellectual property. For instance, in 2020, the global healthcare company Fresenius suffered a ransomware attack that disrupted its operations across four continents.

Businesses are attractive targets because they rely on continuous access to systems and data. An interruption can cost a business thousands, if not millions, in lost productivity and revenue. Furthermore, if your company handles sensitive information (e.g., healthcare, finance, or legal sectors), the reputational damage caused by a ransomware breach can far exceed the ransom demand itself. The ability to protect against ransomware involves understanding that these attacks are financially motivated, and payment does not guarantee the safe return of your data.

What Does the Law Say About Ransomware?

In both the UK and the US, ransomware attacks are criminal offenses, something that is true in many countries elsewhere around the globe. Businesses must comply with specific regulations to protect against ransomware, including laws around data protection and breach reporting.

In the UK, the GDPR mandates that businesses ensure the security of personal data. A ransomware attack can lead to significant fines if it results in a breach of personal data. In fact, the GDPR requires that companies report any data breach to the Information Commissioner’s Office (ICO) within 72 hours. Non-compliance can lead to fines as high as 4% of global annual turnover.

Similarly, in the US, businesses must comply with state and federal laws such as the Computer Fraud and Abuse Act (CFAA), which criminalizes hacking, including ransomware attacks. Additionally, sectors like healthcare fall under HIPAA regulations, which mandate strict reporting of breaches. Failing to adhere to these legal requirements can not only result in penalties but also class-action lawsuits from affected customers or clients.

A prime example is the 2017 WannaCry ransomware attack, which impacted NHS services across the UK. This incident highlighted the potential liability and legal ramifications for businesses failing to secure their systems against ransomware attacks, cybersecurity attacks and others.

How Does Ransomware Get on Your Computer?

Most ransomware attacks begin with a simple email. Phishing campaigns, where attackers trick employees into clicking malicious links or opening infected attachments, are the most common entry points. Once the ransomware is installed, it can spread rapidly through the network. Additionally, attackers exploit vulnerabilities from those who haven’t protected against ransomware e.g., via outdated software, especially when businesses fail to apply patches or updates in time.

Consider the case of the Colonial Pipeline attack in 2021, where outdated VPN software provided the entry point for ransomware. Attackers exploited a known vulnerability, causing the company to shut down its operations and pay a $4.4 million ransom. For business leaders, this highlights the need for a robust patch management system, as well as regular employee training to raise awareness of phishing threats.

What Happens When Ransomware is Activated?

Once ransomware is activated, it typically encrypts essential files or locks the user out of the system entirely. In a business environment, this could mean losing access to financial data, customer records, or even supply chain information. The attackers will usually demand a ransom, often payable in cryptocurrency, in exchange for the decryption key.

When Atlanta’s municipal government didn’t protect against ransomware and was hit by a ransomware attack in 2018, the attackers demanded $51,000 in Bitcoin. The city refused to pay, but the aftermath cost Atlanta a reported $17 million in recovery costs. Businesses must weigh these decisions carefully, as paying a ransom can encourage further attacks, and there’s no guarantee that paying will restore your data. Many organizations now opt for cyber insurance policies that can cover the costs of recovery, though these policies are becoming increasingly expensive due to the rising frequency of attacks.

How to Recover from a Ransomware Attack

Recovering from a ransomware attack requires swift and coordinated action to minimize damage and restore operations:

  • Isolate infected systems: Disconnect the affected computers or servers from the network to prevent further spread.
  • Restore from backups: If you have clean backups, use them to restore systems and data.
  • Engage cybersecurity experts: Use forensic tools to understand the breach and close vulnerabilities.
  • Communicate with stakeholders: Keep employees, customers, and partners informed, especially if their data has been affected.

Recovery, however, is only one part of the equation. If you want to learn how to protect against ransomware, then a proactive, prevention-first mindset is crucial for maintaining long-term security. Some businesses attempt to handle attacks internally but underestimate the expertise required. Working with industry experts can help you not only recover from ransomware but also build stronger defenses to protect against ransomware in the future.

How Does Ransomware Spread?

Ransomware can spread quickly across a business’s network, particularly when it exploits weak points in shared drives, email systems, or software vulnerabilities on PC’s that are not completely protected against ransomware. Attackers may use worm-like features to propagate the malware across multiple systems. The WannaCry attack, for instance, spread through a Microsoft Windows vulnerability, affecting hundreds of thousands of systems in over 150 countries within hours.

For businesses, this means that simply containing one infected computer is often not enough. Network segmentation and strong access controls are crucial to protect against ransomware from moving laterally across systems. Limiting employee access to only the data they need and monitoring network activity can help slow the spread of ransomware and give IT teams more time to respond.

Conclusion

In the current digital landscape, ransomware presents a formidable challenge to businesses, no matter their size. Protecting against ransomware requires a multi-layered approach that includes employee training, up-to-date systems, and strong cyber defenses. However, even with the best internal measures and IT strategies, there is always a risk. Engaging cybersecurity professionals who understand the complexities of these attacks can provide the long-term protection needed to safeguard your business against evolving ransomware threats.
