The Crucial Role of Malware Development Skills for Ethical Hackers in Combatting Ransomware Threats

Cybersecurity is a front-line defense in a world increasingly targeted by cyberattacks. Among these threats, ransomware is particularly alarming, as it can disrupt business operations and lead to massive financial losses. To effectively counteract ransomware and other malicious software, ethical hackers must have a solid understanding of malware. This post explores why malware development skills are vital for ethical hackers, the necessary abilities they need to develop these skills, the types of malware they should study, and some striking statistics about ransomware’s impact.

Understanding the Importance of Malware Development

Ethical hackers are cybersecurity professionals who identify vulnerabilities in systems to prevent cyber threats. One key area of their expertise is malware development. Learning how to create and analyze malware allows ethical hackers to accurately emulate real-world attacks, thereby identifying weaknesses in security systems.

For example, developing custom malware can aid in testing security solutions such as Antivirus (AV) and Endpoint Detection and Response (EDR) tools. This enables professionals to uncover vulnerabilities that standard testing tools might miss. With the increasing sophistication of cyber threats, it is essential for ethical hackers to understand the mechanics of malware. This knowledge is crucial for building robust security measures.

Key Ransomware Statistics (2024–2025)

• Prevalence: Approximately 59% of organizations experienced ransomware attacks in 2024, with 70% of these incidents resulting in data encryption. 

• Financial Impact:

  • The average ransom payment in 2024 was reported at $2.73 million, marking a significant increase from the previous year.

• Attack Vectors:

  • Unpatched vulnerabilities were the entry point in 32% of attacks. 

  • A significant number of organizations attacked in 2023 faced repeat attacks in 2024, often with higher ransom demands.

• Operational Disruption: The average downtime following a ransomware attack was 24 days.

Sector-Specific Impacts

• Healthcare:

  • In 2024, there were 181 confirmed ransomware attacks on healthcare providers, compromising 25.6 million records. The average ransom demand in this sector was $5.7 million. 

  • Notably, the attack on UnitedHealth's subsidiary, Change Healthcare, in February 2024 resulted in estimated damages of $3.09 billion. 

• Retail:

  • Marks & Spencer (M&S) suffered a significant ransomware attack in April 2025, leading to an estimated £60 million in lost profits and over £1 billion in market value. The attack disrupted online operations and supply chains. 

• Automotive:

  • CDK Global, a software provider for car dealerships, was attacked in June 2024. The incident disrupted services across North America, leading to estimated losses of $605 million for dealerships and a $25 million ransom payment.

Emerging Trends

• Ransomware-as-a-Service (RaaS): The RaaS model has lowered the barrier to entry for cybercriminals, leading to a proliferation of ransomware variants and increased attack frequency. 

  
  

• Attackers now often not only encrypt data but also exfiltrate sensitive information and threaten to:

  • Leak it publicly.

  • Notify regulators.

  • Target third parties (suppliers or customers).

  This has led to increased ransom pressure and reputational damage.

  
  

• Stealthier Initial Access

  • Ransomware gangs are relying more on living-off-the-land (LotL) techniques and fileless malware, making detection harder.

  • Initial compromise may stay dormant for weeks before the payload is deployed.

    
    

• Weaponization of Legitimate Tools

  • Attackers increasingly use legitimate IT tools like PowerShell, PsExec, and AnyDesk to move laterally and deploy payloads.

  • This makes attacks blend in with normal activity, bypassing traditional antivirus and EDR solutions.

    
    

• Targeting of Backups and Shadow Copies

  • Ransomware variants are now automatically deleting Volume Shadow Copies and attacking backup systems to prevent recovery.

  • Many organizations find themselves unable to restore data, even if backups exist.

    
    

• Ransomware Deployment via Zero-Day Exploits

  • A growing number of attacks are exploiting zero-day vulnerabilities before patches are released.

  • For example, MOVEit and Citrix Bleed vulnerabilities were exploited at scale within days of disclosure.

    
    

• Targeting of Cloud Services

  • Cloud storage (e.g., S3 buckets), SaaS platforms, and even CI/CD pipelines are now being encrypted or hijacked.

  • The attack surface has expanded beyond traditional endpoints and servers.

• Rise in Attacks on Small & Mid-Sized Enterprises (SMEs)

  • While large enterprises remain prime targets, SMEs with fewer defenses are increasingly exploited as low-hanging fruit.

  • Many SMEs go out of business due to the cost of recovery and reputation loss.

    
    

• Target Shift: Attackers are increasingly focusing on critical infrastructure sectors, including manufacturing, healthcare, and government facilities.

Notable Incidents

• Synnovis (UK): A ransomware attack in June 2024 on Synnovis, a pathology services provider, led to the cancellation of over 800 surgeries in London hospitals. 

• Kadokawa and Niconico (Japan): In June 2024, a ransomware attack by the BlackSuit group disrupted services for nearly two months, affecting over 250,000 users. 

• Ascension (USA): In May 2024, Ascension, a major healthcare network, experienced a ransomware attack that disrupted electronic medical records and other critical systems.

These incidents underscore the evolving threat landscape of ransomware attacks. Organizations are advised to bolster their cybersecurity measures, including regular system updates, employee training, and robust backup solutions, to mitigate the risks associated with such attacks.
