In 2024, ransomware attacks remain a persistent and formidable threat to organisations worldwide. Despite a slight decline in the percentage of companies affected compared to previous years, the growing sophistication and financial impact of these attacks continue to put businesses at significant risk. In fact, ransomware ranks as the number one threat to organisations across 92% of industries - according to the latest Verizon research.
This article explores the current landscape of ransomware, the industries most affected, and the substantial financial and operational implications. We also discuss how an out-of-band communications platform, like Sentinel, can help organisations mitigate the impact of these attacks.
Frequency of Ransomware Attacks
While 59% of organisations were hit by ransomware attacks in 2024 - a slight decrease from the 66% reported in prior years - the broader trend remains concerning, with ransomware incidents rising by 13% over the last five years. Certain industries, such as healthcare, have seen even sharper increases. The healthcare sector experienced a 7% rise in attacks, with 67% of organisations affected, while financial services faced a consistent attack rate of 65% over the past two years.
Globally, there is a trend of ransomware attacks spiking across different geographic regions, with certain countries facing higher attack rates. In a recent report from Sophos, France reported the highest incidence of attacks at 74%, followed closely by South Africa at 69% and Italy at 68%. On the other end of the spectrum, Brazil recorded the lowest rate at 44%, alongside Japan at 51% and Australia at 54%. These variations highlight that no region or industry is immune, underscoring the global scope of the ransomware threat.
The Financial and Operational Impact of Ransomware
The financial repercussions of ransomware are increasingly severe. In 2024, the average ransom demand soared to $2.73 million - an increase of nearly $1 million from the previous year. The average recovery cost across sectors is close to $2 million, with financial services firms bearing an even higher burden, averaging $2.58 million in recovery costs.
Beyond the direct financial costs, ransomware attacks can bring organisations to a standstill. On average, companies experience 21 days of downtime following a ransomware attack, severely affecting productivity and business continuity. In the financial sector alone, 43% of computers were affected in the average attack, disrupting critical operations.
Data Encryption and Ransom Payments
One of the most devastating aspects of ransomware attacks is the encryption of sensitive data. Seventy percent of attacks in 2024 resulted in data encryption, though 97% of organisations that experienced encryption were able to recover their data, often by paying the ransom. Globally, 56% of organisations paid the ransom, with the financial services sector seeing 51% of organisations opting to pay.
While paying the ransom might seem like the quickest route to data recovery, it’s not without risks. The payment does not guarantee full data restoration or the prevention of future attacks. Instead, it often emboldens cybercriminals to continue their efforts.
Key Ransomware Trends in 2024
Several trends define the ransomware landscape in 2024. Notably, 32% of attacks exploited unpatched vulnerabilities, making it clear that even basic cybersecurity hygiene—such as timely software updates—can prevent many incidents. Vendor-related breaches also grew significantly, accounting for 40% of ransomware claims this year, up from 35% in 2023. Manufacturing and construction sectors were particularly hard-hit, seeing substantial increases in claims due to ransomware.
These trends illustrate the expanding attack surface for ransomware, as organisations rely on more third-party vendors and operate complex digital supply chains. The increase in vendor-related breaches also emphasises the need for strong incident response plans that account for external dependencies.
Why Organisations Need Out-of-Band Communications for Ransomware Response
Given the significant disruption ransomware can cause, having robust, out-of-band communication systems is crucial for minimising the impact. Out-of-band communication refers to using an independent channel outside the affected network, allowing organisations to coordinate a response when their primary systems are compromised. This is where platforms like Sentinel play an essential role.
Sentinel provides an independent, secure communications channel, enabling organisations to maintain real-time coordination during a ransomware attack. By using Sentinel, key stakeholders can communicate effectively without relying on compromised systems, helping to resolve incidents faster and with greater precision. The platform’s secure environment also protects against further cybercriminal exploitation during an attack, ensuring that response efforts are not disrupted.
Furthermore, an out-of-band communication system can facilitate post-attack recovery by enabling seamless collaboration with external cybersecurity experts and law enforcement. With ransomware continuing to evolve and threaten organisations across industries, incorporating a secure communication solution like Sentinel can significantly improve an organisation’s resilience and ability to recover swiftly from attacks.
Conclusion
As ransomware attacks continue to evolve and grow in sophistication, the threat remains pervasive in 2024. The financial and operational impacts are devastating, with organisations across industries facing increasing costs, downtime, and data encryption. Despite this, many organisations remain unprepared to respond effectively.
Investing in out-of-band communication platforms like Sentinel offers a critical layer of protection, enabling organisations to manage and mitigate the effects of ransomware attacks swiftly. In today’s cyber threat landscape, no organisation can afford to overlook the importance of having resilient, independent communication channels as part of their incident response strategy.
