How to Reduce the Risk of Ransomware? A Detailed Guide

Highlights:

• Ransomware attackers usually begin by exploiting weak points, conducting reconnaissance to target domain admins and escalate their attack.
• Cybersecurity professionals face evolving threats, with ransomware posing a persistent risk. Business continuity requires a multi-layered defense to mitigate attacks.

Recent ransomware incidents highlight severe impacts, from halted casino operations to nationwide fuel shortages.

When ransomware disrupts operations, every hour of downtime drains cash reserves and risks customer trust.

Beyond downtime costs, risks include data loss, reputational damage, legal issues, and ransom payments. In 2023, victims paid USD 1.1 billion as per Actual Tech Media.

It shows ransomware remains a top cybersecurity concern, with rising attack costs despite significant investments.

As a result, high-profile incidents have drawn public and regulatory attention. This blog unveils why ransomware persists and highlights five strategies to know how to reduce the risk of ransomware?

Why Does Ransomware Remain a Continuous Threat?

Organizations face an asymmetric battle against ransomware actors, as it’s easier and cheaper to attack than defend. Ransomware’s profitability drives specialized, persistent cybercriminal gangs operating within a dynamic ecosystem.

These groups, resembling traditional businesses, employ partnerships, revenue models, and evolving tactics. They use automation to identify vulnerabilities, attacking at victims’ weakest points.

Cybersecurity budgets often face scrutiny, making it challenging to allocate sufficient resources for risk mitigation. Like car insurance, the value of investment becomes evident only after an incident.

Look into the evolving ransomware threats:

• RaaS sophistication: Ransomware-as-a-service tools are increasingly advanced, lowering barriers for attackers while splintering the threat landscape, complicating attribution and intelligence.
• RMM exploitation: Cybercriminals exploit remote monitoring and management software for persistent access, command, and data exfiltration, testing multiple tools to bypass firewalls.
• Compromised identity management: Attackers exploit MFA vulnerabilities to intercept tokens and bypass defenses, increasing risks for enterprise systems.

Chasing the Challenges of Complex Security Landscape

Humans are our greatest resource, yet cybersecurity faces a severe talent shortage, with a gap of nearly 4 million workers in 2023.

Rapid digital transformation has created complex environments, compounded by the use of over 40 tools in most organizations, leading to alert fatigue.

In defence, security teams must balance patching vulnerabilities, maintaining hygiene, meeting compliance, and threat hunting. It makes effective prioritization an essential thing.

Greatest liability: Most ransomware attacks exploit human error, like clicking phishing emails or visiting unsafe websites.

The risk has grown with AI tools generating convincing phishing emails at scale. Hence, organizations should assume some level of human error and design systems to mitigate it.

Secure Your Organization: A Roadmap to Ransomware Resilience

Continuous threat actors and limited organizational resources helps to increase ransomware risks.

The following five impactful strategies tell you how to defend against ransomware, strengthen security and respond effectively to incidents.

1. Illuminate hidden threats

Attackers seek the path of least resistance, targeting areas where IT lacks visibility, such as unmanaged devices, shadow IT, or legacy systems.

Organizations must adopt a disciplined approach to maintain an up-to-date asset list and use the right tools to discover devices and increase visibility. This helps prevent ransomware from exploiting overlooked resources.

2. Prevent patient zero with identity protection

Ransomware attackers often start with weak points, then move laterally to compromise other targets. A typical first step is reconnaissance, identifying domain admins to elevate privileges and escalate their attack.

To prevent this, organizations must protect identities from initial compromise and prevent a single breach from becoming widespread.

Social engineering challenges: Sophisticated attacks use social engineering attacks and AI-powered phishing to trick users into compromising credentials.

Security teams must assume some users will make mistakes and implement training, simulated phishing, and role-based education to mitigate risks.

MFA: It remains essential for protecting against brute force and stolen credential attacks. Even minimal disruptions can significantly reduce security risks.

Cloud identities: They are prime targets for phishing and brute force attacks. A compromised container can lead to a larger breach, making protection crucial.

Finally, detect compromised identities unusual behaviors like failed logins or unusual data export activity can signal a compromised identity.

AI-driven tools can help detect these deviations. Here is a security hygiene checklist:

• Use strong passwords and rotate regularly
• Implement MFA, especially for BYOD policies
• Maintain accurate domain admin contact info
• Limit domain admin access
• Apply the principle of least privilege
• Automate provisioning and deprovisioning tasks.

3. Block, disrupt, and misdirect lateral movement

Assume a breach is inevitable. With cloud computing, remote work, and evolving threats like credential theft and supply chain attacks, planning for intruders is crucial.

Attackers often move laterally to escalate privileges, targeting vulnerable devices or identities. Their steps typically include:

• Reconnaissance: Identifying weaknesses while avoiding detection.
• Persistence: Creating backdoors for continued access.
• Lateral movement: Gaining privileged credentials to move further in the network.

Finally, network segmentation blocks lateral movement by isolating sensitive areas, limiting access across the network. Deception technologies mislead attackers by providing decoys that waste their time and increase the chance of detection, making the organization a less appealing target.

4. Help threat hunters focus and prioritize

Ransomware attacks are growing, making metrics like mean time to detect and respond (MTTD and MTTR) critical. Security teams must remain curious and question suspicious activity, as timely inquiries can stop attacks.

However, overloaded analysts, an absence of cybersecurity talent, and complex threat-hunting syntax hamper effective threat detection. Alert fatigue further impedes prioritization.

To solve these challenges, organizations must focus on empowering security teams through actionable dashboards. These tools consolidate data across silos, provide real-time updates, and present normalized information tailored to specific roles, enabling informed decisions and effective workflows.

Threat intelligence assist organizations navigate a dynamic threat landscape, providing essential context to accelerate detection and response (MTTD and MTTR). However, prioritizing threats and vulnerabilities remains challenging. By mixing threat intelligence with environmental data like telemetry and network traffic, AI can verify relevant risks and recommend significant steps.

Generative AI improves threat hunting by simplifying query creation with natural language, making data analysis more accessible and efficient. It summarizes threat results conversationally, suggests follow-up queries, and lowers alert fatigue by guiding prioritization and triggering automated workflows. This changes how teams detect, investigate, and replies to threats.

5. Test a worst-case scenario plan

Investing in incident response is necessary, as prevention alone can’t tackle the uncertainties of difficult environments, like human error and evolving threats.

A strong incident response plan reduces decision-making during high-stress ransomware attacks by defining roles, communication channels, breach disclosure policies, and recovery procedures.

Simulating worst-case scenarios ensures readiness, while selecting effective recovery technologies mitigates costly downtime.

In this way, the risk of ransomware can be avoided.

Maintain Business Continuity and Protect Against Ransomware

Cybersecurity professionals face evolving, opportunistic threats, with ransomware remaining a persistent risk. Ensuring business continuity requires a multi-layered defense to resist and mitigate attacks.

Selecting the right partners is crucial as it offers unique solutions to combat threats at every possible stage, such as:

• Vulnerability and exposure management
• Deception tools to disrupt and mislead attackers
• Generative AI, dashboards, and effective threat intelligence for threat hunters
• Rollback remediation for business continuity.
