How Do Ransomeware Gangs Operate?

Ransomware reached record levels in 2025, with 7,960 victims listed on double-extortion leak sites, marking a 53% increase year-over-year. According to the 2026 CrowdStrike Global Threat Report, average breakout times have dropped to record lows, meaning attackers are moving from initial access to full encryption faster than ever before.

This article explains the inner workings of ransomware gangs, detailing their organizational structure, attack methodologies, and the steps organizations can take to protect themselves. By grasping the business-like operations and tactics of these cybercriminal groups, decision-makers can better anticipate, prevent, and respond to ransomware attacks.

Ransomware gangs are outpacing traditional security solutions, leaving defenders stuck playing a constant game of catch-up.

Summary

Ransomware gangs work as organized and hierarchical entities, executing ransomware attacks through various stages such as gaining initial access, encrypting data, negotiating with victims, and sometimes engaging in data exfiltration. These groups typically employ a division-of-labor model, allowing for coordinated attacks that are both stealthy and effective. Their hierarchical structure consists of specialized roles — developers who create the ransomware software, operators who manage technical deployment and lateral movement, affiliates who are external hackers executing attacks for a share of the ransom, and negotiators who handle communications and extortion. By understanding this structured approach, IT professionals and business leaders can better anticipate the tactics of ransomware gangs and implement more effective defenses against these persistent threats.

Introduction to Ransomware

Ransomware represents one of today’s most devastating cyber threats — malicious software engineered to encrypt victims’ files or completely lock down their systems, holding critical data hostage until attackers receive payment. The threat landscape has shifted significantly; while simple encryption used to be the goal, the Unit 42 Incident Response Report notes that nearly 90% of modern cases involve identity-driven access and data exfiltration.

Fortune 500 companies have become primary targets due to their deep pockets and complex networks. Cybercriminal organizations deploy a sophisticated playbook, including:

• Credential Harvesting: Stealing identities to "log in" rather than "break in."
• Zero-Day Exploits: Exploiting unpatched software vulnerabilities before fixes are available.
• Privilege Escalation: Spending weeks moving through environments to identify high-value assets.

Ransomware groups constantly update or switch malware strains to evade detection and enhance their operational capabilities, making them increasingly difficult to defend against. The endgame is always the same: victims face a stark ultimatum demanding cryptocurrency payment for decryption keys, frequently accompanied by threats to leak stolen data on underground forums. As these criminal enterprises continue evolving their tactics, understanding their operational methodologies has become critical for organizations building effective ransomware defenses.

Ransomware groups typically operate through a division-of-labor model, allowing for coordinated attacks that are stealthy and effective. This means that each member of the group has a specialized role, contributing to the overall success of the operation. Ransomware groups have a hierarchical structure consisting of various roles, such as developers, operators, affiliates, and negotiators, which enables them to function much like legitimate business organizations.

How Ransomware Gangs Operate: Step-by-Step

To understand how ransomware works, it is important to know that attackers typically gain access to an organization's systems through phishing emails, exploiting vulnerabilities, or using stolen credentials. Once inside the victim's network, they encrypt files and then demand a ransom payment from the victim to restore access.

The Hierarchical Structure of Ransomware Gangs

Modern ransomware gangs operate as organized entities to execute ransomware attacks on various targets, including individuals, businesses, and government institutions. These ransomware groups typically operate through a division-of-labor model, allowing for coordinated attacks that are stealthy and effective.

Within this hierarchical structure, specific roles ensure the success of ransomware operations:

• Developers: Developers within ransomware groups are responsible for creating the malicious ransomware software that encrypts victim’s files. They design, code, and update different malware strains to evade detection from Endpoint Detection and Response (EDR) tools and maximize operational effectiveness, frequently modifying or switching strains to bypass security measures.
• Operators: Operators manage the technical aspects of ransomware attacks, including deploying the ransomware and moving laterally across networks. They are responsible for executing the attack plan and ensuring the malware reaches critical systems.
• Affiliates: Affiliates in ransomware groups are external hackers recruited to carry out attacks on behalf of the group in exchange for a percentage of the ransom payment. They often handle the initial compromise and delivery of the ransomware payload.
• Negotiators: Negotiators within ransomware groups communicate with victims to handle ransom payment negotiations and provide assistance after an attack. They are skilled in psychological tactics and often manage the extortion process.

With this structure in mind, let’s explore how these groups execute their attacks in practice.

Understanding Ransomware Gangs

Today’s ransomware operations have evolved far beyond the stereotypical image of lone hackers working from basement computers. These criminal enterprises function as sophisticated business organizations, complete with specialized roles and clear command structures that would be recognizable in any corporate environment. Within these groups, individual operators focus on distinct phases of the attack lifecycle — some concentrate on initial network penetration, others handle data exfiltration, while still others manage the delicate art of ransom negotiations. The target selection process itself reflects this professionalism, as these groups systematically identify organizations with high-value data assets and conduct thorough reconnaissance before launching their campaigns. 

Modern ransomware operations have increasingly embraced what security researchers term “double extortion” — a particularly insidious approach where attackers steal sensitive data before deploying encryption, then leverage both data recovery and public exposure as pressure points. Ransomware gangs often steal sensitive data before encrypting the victim's data, threatening to release it unless the ransom is paid. This dual-threat model has proven devastatingly effective at compelling payment, as victims face not only operational disruption but potential regulatory penalties and reputational damage. 

Today's most active ransomware gangs include Cl0p, Akira, and RansomHub, which collectively claimed 770 victims in the first three months of 2025. In the first quarter of 2025 alone, ransomware groups targeted 2,028 known victims, a 100%+ increase over the same period in 2024. There are currently 65 active ransomware groups operating, up from 47 a year ago, marking a 38% increase. The success of this model is perhaps best illustrated by groups like REvil and LockBit, whose coordinated campaigns have resulted in some of the most significant cyber incidents of the past several years, fundamentally reshaping how organizations approach ransomware preparedness.

As we move forward, let’s examine the business models that have enabled ransomware gangs to scale their operations globally.

The Business of Ransomware as a Service (RaaS)

The ransomware as a service (RaaS) business model is booming. This model allows affiliates to execute attacks while RaaS operators maintain the infrastructure and collect a portion of the profits. This has allowed the number of threat actors to explode; there are currently 65 active ransomware groups operate, up from 47 a year ago.

Notorious ransomware gang names like REvil, Cl0p, Akira, and RansomHub have dominated the ransomware landscape. For example, REvil is a notorious ransomware gang responsible for high-profile breaches like Kaseya and JBS, while Egregor is a ransomware-as-a-service gang that has claimed at least 70 victims and extorted tens of millions of dollars.

Understanding the RaaS model helps clarify how ransomware gangs can rapidly expand their reach and adapt to new targets.

The Role of Ransomware Attackers

Ransomware attackers serve as the operational engines driving today's most sophisticated cybercriminal enterprises, wielding technical expertise that has evolved far beyond the script-kiddie stereotypes of years past. These threat actors — whether working as individuals or coordinated teams — have mastered the art of initial network compromise, deploying everything from meticulously engineered spear-phishing campaigns to zero-day exploits that slip past even well-maintained security infrastructures.

Lateral Movement and Privilege Escalation

What happens next represents a calculated progression that security teams know all too well: lateral movement through compromised networks, privilege escalation using living-off-the-land techniques, and detection evasion that can keep attackers hidden for weeks or months.

Supply Chain Attacks

The sophistication doesn't stop there — modern ransomware operators increasingly target supply chain vulnerabilities, compromising trusted third-party vendors as stepping stones to their real prizes. Their endgame remains brutally effective: exfiltrating valuable data before deploying file-encrypting malware that brings entire organizations to a standstill, then demanding cryptocurrency payments for decryption keys that may or may not work as promised. Perhaps most concerning for defenders is how rapidly these attackers iterate and adapt, turning each successful breach into a learning opportunity that makes the next attack even more dangerous.

With an understanding of the attackers' roles and tactics, let's look at how they gain initial access to their targets.

Initial Access: How Ransomware Attackers Enter the Network

To gain initial access, ransomware attackers often target an organization's systems through three primary vectors: phishing attacks, compromised credentials, or exploiting vulnerabilities. Once inside, attackers move laterally within the victim's network to maximize their control and impact.

Phishing Attacks and Malicious Attachments

Phishing emails remain a common method used by ransomware gangs. These groups often use spear phishing emails, which are highly targeted messages containing malicious attachments, to trick specific individuals into providing initial access to the victim’s network.

Exploiting Vulnerabilities

Ransomware operators frequently target unpatched vulnerabilities, software vulnerabilities, and VPN vulnerabilities. Initial access brokers often sell initial network access to these software vulnerabilities on the dark web, allowing ransomware actors to gain access and begin deploying ransomware immediately.

After gaining access, attackers escalate their privileges and begin the process of data exfiltration and encryption.

Escalation and Data Exfiltration

Once ransomware attackers gain initial access, they move to escalate privileges to reach critical systems and sensitive information. Ransomware attacks can achieve data exfiltration within the first hour of compromise, highlighting the speed of modern attacks.

Double Extortion and Data Theft

Many ransomware gangs, such as Black Basta, DoppelPaymer, and Maze, steal sensitive information as part of their double extortion tactics. In these attacks, they gain access to the victim's data, exfiltrate it, and then initiate data encryption. The attackers threaten to release the victim's data on the dark web unless the ransomware victim pays. Maze was actually the first to combine file encryption and data theft in this manner.

With data exfiltration complete, the next step is file encryption and ransom demand.

Encryption and the Ransom Note

After exfiltrating sensitive data, ransomware operators use strong encryption algorithms to encrypt the victim's files, making them inaccessible without a decryption key. Once the victim's files are encrypted, the ransomware strain displays a ransom note on affected systems.

This ransom note informs the ransomware victim about the encrypted victim's files and provides instructions on how to gain access to the decryption key by making a ransom payment, usually in cryptocurrency to make transactions harder to trace.

The ransom note sets the stage for a critical decision: whether or not to pay the ransom.

Paying Ransoms: A Complex Decision

The average cost of a ransomware attack hit $4.91 million last year. When faced with a ransom demand, organizations must decide if paying ransoms is the right path. Law enforcement and legal experts generally advise against it, as there is no guarantee that paying will lead to successful recovery from ransomware attacks.

The Consequences of Paying Ransoms

The decision to pay ransomware demands sets off a dangerous chain reaction that extends far beyond immediate data recovery concerns. Every ransom payment directly bankrolls criminal enterprises, providing threat actors with fresh capital to develop more sophisticated attack tools and expand their operations across new targets. This financial lifeline effectively perpetuates an escalating cycle where today's payment becomes tomorrow's larger, more devastating campaign against other organizations. What makes these transactions particularly risky is the fundamental uncertainty involved — victims have no assurance they'll receive functional decryption keys or that their stolen data won't still surface on underground markets. The anonymity that shrouds these criminal operations compounds the problem significantly, creating substantial obstacles for law enforcement agencies attempting to track down perpetrators or disrupt their infrastructure. This reality drives the consistent guidance from federal agencies and security experts: paying ransoms not only incentivizes additional attacks but actively undermines broader efforts to dismantle these criminal networks and protect the wider business community from future threats.

Best Practices for Negotiation

If an organization enters negotiations, they should:

• Establish a dedicated team for effective communication.
• Document all communication and negotiation details.
• Engage with a cyber insurance company.
• Consult law enforcement to understand the legal implications.
• Maintain a professional and composed tone.

Understanding the risks and best practices around ransom payments is crucial for informed decision-making. Next, let's discuss how organizations can reduce their risk of becoming a victim.

Mitigating the Effects of Ransomware Attacks

Building effective defenses against ransomware attacks demands a comprehensive, multi-layered approach that spans the entire attack lifecycle. Today's ransomware operators have refined their techniques, exploiting system vulnerabilities, deploying sophisticated phishing campaigns, and targeting high-value data assets. Organizations can no longer afford reactive security postures — they must actively close these attack vectors before cybercriminals exploit them. The foundation of any robust defense starts with prevention. Regular software updates and systematic patch management remain critical for eliminating the vulnerabilities that ransomware groups consistently target during initial compromise attempts. Employee education proves equally essential, particularly given that phishing remains the preferred entry point for most ransomware campaigns. Training staff to identify suspicious emails and recognize malicious attachments can effectively neutralize threats before they penetrate network perimeters.

However, prevention alone isn't sufficient in today's threat landscape. Organizations need advanced threat detection capabilities that can spot anomalous network behavior and intercept ransomware payloads before they execute. Zero-trust architecture has emerged as a particularly effective strategy for containing ransomware spread, limiting attackers' ability to move laterally through compromised networks and reducing exposure to data exfiltration and double extortion schemes. When ransomware does penetrate organizational defenses, immutable backup systems that undergo regular testing become the difference between rapid recovery and prolonged operational disruption. These backups eliminate the need to consider ransom payments while ensuring business continuity. Security teams must also stay current on emerging ransomware variants and evolving tactics from established threat groups. The ransomware landscape shifts rapidly, with new attack methods and evasion techniques appearing regularly. Organizations that integrate these defensive strategies create resilient security postures capable of withstanding sophisticated ransomware campaigns while protecting critical data assets from compromise.

Reducing Your Attack Surface: Best Practices

Ransomware gangs operate by finding the path of least resistance. Before launching an attack, they carefully assess the target organization to identify vulnerabilities and plan their attacks. Fortune 500 companies have become primary targets due to their deep pockets and a vast attack surface created by technical debt.

To evade detection and protect critical data, organizations must go beyond traditional security solutions. Ransomware attackers are increasingly leveraging tools known as “EDR killers” to sidestep defenses. Effective best practices include:

• Regular data backups: Restoring from backups is the best way to ignore a ransom demand.
• Continuous monitoring: Detecting ransomware infection before encrypted data locks the system and monitoring user behavior to catch ransomware operators early.
• Privilege escalation protection: Limiting user accounts to prevent lateral movement.

By implementing these best practices, organizations can significantly reduce their exposure to ransomware threats.

Conclusion

Ransomware continues to represent one of the most significant threats facing organizations today, with criminal groups operating sophisticated, profit-driven enterprises that target victims across every industry sector. These threat actors deploy a calculated mix of social engineering, vulnerability exploitation, and data encryption tactics to penetrate networks and hold critical systems hostage. The financial and operational impact can be devastating — forcing companies to weigh costly ransom demands against prolonged business disruptions. Smart defense strategies center on proactive measures: maintaining reliable backup systems, deploying advanced detection capabilities, and implementing zero-trust frameworks that restrict lateral movement once attackers gain initial access.

Success in combating ransomware requires more than just defensive tools. Security teams need current intelligence on how these criminal operations evolve their methods and introduce new variants into the threat landscape. Equally critical is establishing comprehensive recovery capabilities, particularly immutable backup solutions that remain protected even during active attacks. Organizations that invest in prevention, maintain continuous monitoring, and develop tested recovery procedures significantly reduce their exposure to ransomware incidents. The goal isn't just avoiding ransom payments — it's ensuring business continuity and protecting sensitive data against increasingly sophisticated criminal enterprises.
