Ransomware’s Journey: From Basic Encryption to Advanced Extortion Tactics
From floppy disks to global cyber crises, ransomware has evolved from $189 demands to multi-billion-dollar double extortion schemes. Discover how state-sponsored actors and AI are reshaping this escalating threat — and why ransomware’s future is more complex than ever.
The ransomware landscape has undergone remarkable transformations over the last three decades, evolving from simple digital threats to sophisticated, multi-layered attacks. This progression reflects the advancements in technology and also the professionalization of cybercriminal operations. Today, ransomware is a multi-billion-dollar global menace, capable of crippling critical industries and governments alike. Its history is not merely a story of technological evolution but also a tale of shifting tactics, targets, and strategies as cybercriminals adapt to an ever-changing digital world.
The Humble Beginnings: AIDS Trojan (1989)
Ransomware’s story begins in 1989 with the AIDS Trojan, also known as PC Cyborg. Distributed via 20,000 floppy disks sent to attendees of a global AIDS conference, this rudimentary malware encrypted filenames and demanded $189 sent to a Panamanian P.O. box for recovery. Though primitive and largely ineffective, it was a harbinger of things to come. Victims faced limited payment options, and a decryption tool was soon created, nullifying its impact.
During the 1990s, ransomware remained an outlier in the cybercrime ecosystem, constrained by the lack of widespread digital payment systems and interconnected networks. The groundwork, however, was being laid. Cybercriminals began exploring ways to exploit emerging technologies to increase their reach and effectiveness, setting the stage for the seismic shifts that followed.
The Early Days of Modern Ransomware (2004–2007)
The early 2000s marked the first significant shift in ransomware tactics. As technology advanced and digital systems became more integral to everyday life, ransomware evolved to exploit these new vulnerabilities:
- GPCoder (2005): This malware encrypted data files like documents and spreadsheets, leaving ransom notes in affected directories. It set the stage for future ransomware attacks with demands for payment via Western Union, a method that, while cumbersome, allowed cybercriminals to collect their ransoms more efficiently than the AIDS Trojan.
- Archievus (2005): Introduced RSA encryption, targeting files in the “My Documents” folder. Despite technological advancements, its impact was limited due to a shared decryption key. However, it demonstrated a growing sophistication in the use of encryption algorithms.
- Locker Ransomware (2007): Unlike file encryption variants, Locker ransomware disabled essential system functions, locking victims out of their devices entirely. Payment demands ranged from premium-rate SMS to Western Union transfers, showcasing a diversification in monetization strategies.
These early developments reflected a trial-and-error phase as ransomware creators experimented with different methods to maximize their impact and profitability.

Cryptocurrency and Ransomware-as-a-Service (2009–2012)
The advent of cryptocurrencies revolutionized ransomware. Bitcoin, introduced in 2009, provided cybercriminals with an anonymous, decentralized payment method. This innovation removed the logistical challenges associated with traditional payment methods and paved the way for a new era of ransomware attacks.
By 2012, Ransomware-as-a-Service (RaaS) emerged, democratizing ransomware operations. Reveton, one of the first RaaS strains, masqueraded as law enforcement to coerce victims into paying fines. Meanwhile, scareware tactics gained popularity, exploiting fear rather than encryption to extract payments from victims. The combination of cryptocurrency and RaaS lowered the barrier to entry for cybercriminals, enabling even those with limited technical expertise to participate in ransomware schemes.
The Rise of Global Threats (2013–2016)
Between 2013 and 2016, ransomware grew exponentially in both scale and sophistication:
- CryptoLocker (2013): This strain popularized encryption-based extortion using public-private key encryption and botnets for distribution. Victims paid an estimated $27 million before its takedown in 2014. CryptoLocker set the standard for future ransomware attacks, demonstrating the devastating potential of encryption-based extortion.
- Locky and Petya (2016): Locky targeted victims via phishing campaigns, while Petya attacked system boot records, crippling entire networks. Petya’s ability to target critical system files signaled a shift towards more aggressive and destructive ransomware tactics. These attacks highlighted the growing scale and sophistication of ransomware, as well as its potential to disrupt entire organizations.
Ransomware Goes Geopolitical: WannaCry and NotPetya (2017)
In 2017, ransomware crossed into geopolitical territory, demonstrating its potential as a tool for state-sponsored cyber operations:
- WannaCry: Leveraging the EternalBlue exploit, this worm infected over 150 countries, disrupting critical services like healthcare. Despite its global impact, a kill switch discovered by a security researcher mitigated further damage. The attack was attributed to North Korea, underscoring the increasing role of state actors in ransomware operations.
- NotPetya: Initially targeting Ukraine, this malware disguised itself as ransomware but acted as a wiper, destroying data irrecoverably. Its links to Russian state actors underscored the role of ransomware in geopolitical conflict, highlighting how cyberattacks could be used to achieve strategic objectives beyond financial gain.
Big Game Hunting and Double Extortion (2018–2020)
By 2018, ransomware attacks began targeting high-value organizations, including governments, healthcare providers, and industrial companies. This shift, known as “big game hunting,” was driven by the realization that these entities were more likely to pay large ransoms to minimize operational disruptions. Simultaneously, double extortion tactics emerged, pioneered by strains like Maze:
- Encrypting data.
- Exfiltrating sensitive information and threatening public exposure.
Dedicated leak sites on the dark web amplified the pressure on victims, making backups insufficient protection against these attacks. These developments marked a significant escalation in the ransomware threat, as attackers sought to maximize their leverage over victims.
Triple Extortion and Beyond (2020–2023)
Ransomware evolved further with triple extortion strategies, adding Distributed Denial-of-Service (DDoS) attacks and regulatory exploitation to their arsenal. For example, attackers reported breaches to regulators to amplify victim pressure. High-profile attacks, such as the Colonial Pipeline incident in 2021, underscored the real-world ramifications of ransomware on critical infrastructure.
Additionally, Initial Access Brokers (IABs) became integral to ransomware operations, selling access to compromised networks. This collaboration fueled the growth of Ransomware-as-a-Service platforms like LockBit, enabling even novice hackers to launch sophisticated attacks. The combination of triple extortion, IABs, and RaaS platforms created a thriving ecosystem for ransomware operations, making them more resilient and adaptable than ever before.

The Road Ahead: Ransomware in 2024 and Beyond
The future of ransomware is poised for greater complexity. Hyper-targeted, AI-driven attacks will exploit vulnerabilities in critical infrastructure and supply chains. Multi-layered extortion attempts will become the norm, combining data theft, public exposure, and operational disruptions. Ransomware attacks may also increasingly target emerging technologies like the Internet of Things (IoT) and Operational Technology (OT) systems, creating new challenges for defenders.
Governments worldwide are implementing stricter regulations to curb ransomware payments, aiming to dismantle the profitability of these schemes. However, threat actors are adapting, leveraging automation and reconnaissance to stay ahead of defenses.
As ransomware techniques continue to evolve, so must our defenses. Organizations need proactive strategies, including real-time threat intelligence, robust backup protocols, and employee training, to mitigate these growing risks. Collaboration between governments, private companies, and cybersecurity experts is essential to counteract the growing ransomware threat. The fight against ransomware is far from over, but with vigilance and innovation, we can stay one step ahead.
