What is Ransomware?

Ransomware is a type of malicious software designed to encrypt a victim’s files or lock them out of their own computer or network. Upon infiltrating a system, ransomware usually displays a message outlining the ransom amount and payment details, usually in cryptocurrency, in exchange for providing the decryption key or restoring access. Some advanced variants might also exfiltrate data, threatening to leak it online if the ransom is not paid. Ransomware attacks are a significant threat for several reasons:

  1. Data Encryption: Ransomware encrypts a victim’s data, making it inaccessible. This includes personal files, business-critical data, and sometimes even entire databases. Without the decryption key, this data becomes effectively useless.
  2. Financial Extortion: Attackers demand a ransom payment from victims, often in Bitcoin or other cryptocurrencies, which makes it difficult to trace. The victim is left with a difficult choice: pay the ransom and hope to regain access to their data or refuse to pay and potentially lose valuable information.
  3. Disruption of Operations: For businesses and organizations, ransomware can disrupt daily operations, leading to downtime, loss of productivity, and financial losses. This can be especially damaging for critical infrastructure and healthcare systems.
  4. Data Loss and Theft: In addition to encrypting data, some ransomware strains threaten to leak sensitive information if the ransom is not paid. This creates a double bind for victims, as they must decide between paying the ransom or risking data exposure.
  5. Widespread Impact: Ransomware attacks can affect individuals, small businesses, large corporations, and even government entities. No one is immune to the threat, and attackers often target vulnerable systems.
  6. Sophistication and Adaptability: Ransomware attacks have evolved to become highly sophisticated. Attackers use advanced encryption techniques and social engineering tactics to deceive users. They also adapt to security measures, making it challenging to defend against new variants.

Crypto Ransomware: The Silent Encryptor

Crypto Ransomware is a type of ransomware that encrypts files on a victim’s computer, rendering them inaccessible. The attacker then demands a ransom, usually in cryptocurrency, for the decryption key.

Examples and Case Studies:
Ryuk: This ransomware is spread mainly via malicious emails and has been responsible for attacks in 2019 and 2020. The ransom amount can exceed USD 300,000, making Ryuk one of the most expensive ransomware in history. Source

Colonial Pipeline: This was a significant case where ransomware led to the shutdown of a major U.S. pipeline, affecting fuel supply. The attackers demanded a cryptocurrency ransom of nearly $5 million and recovered $2.3 million worth of bitcoins transferred. Source: Forbes

Locker Ransomware: The Digital Locksmith

Locker Ransomware locks the user out of their computer system, making it impossible to access any files or applications. The attacker then demands a ransom to unlock the system.

LockerGoga: This ransomware targets industrial firms and is relatively rare compared to other forms. It has been known to cripple entire organizations. 

Emerging Variations and Trends

Ransomware attacks are becoming more targeted and sophisticated. New variations are emerging that combine the features of both crypto and locker ransomware, making them even more dangerous. Multi-stage attacks involving initial reconnaissance and data exfiltration are becoming more common.

Understanding the types of ransomware and their method of operation is crucial for both individual and organizational cybersecurity. As ransomware continues to evolve, staying informed and prepared is the best defence against these insidious attacks.


The Genesis Era: Late 1980

In the late 1980s, the world was introduced to ransomware through the AIDS Trojan, also known as the PC Cyborg. Created by Dr. Joseph Popp, this early form of ransomware was distributed via floppy disks and targeted the healthcare industry. Unlike today’s sophisticated attacks, the AIDS Trojan used basic symmetric encryption, making it relatively easy to remove.

The Dormant Years: 1990s to Mid-2000s

After the AIDS Trojan, ransomware went into a sort of hibernation. While the concept existed, it wasn’t as prevalent or as sophisticated as it is today. The late ’90s and early 2000s saw the rise of various forms of malware, but ransomware was not yet a significant player in the landscape.

The Awakening: Mid-2000s

The mid-2000s marked a turning point for ransomware. It was during this period that ransomware attacks started becoming more common. The attacks were no longer just nuisances; they began to pose a real threat. Organizations started to take notice as ransomware became more advanced, often involving multi-stage attacks that could cripple entire networks.

The Era of Specialization: Late 2010s

As we moved into the late 2010s, ransomware had evolved into a highly specialized form of cyberattack. No longer just a tool for petty cybercriminals, it became a weapon of choice for organized crime syndicates. Different types of ransomware emerged, each with unique methods of attack—from crypto ransomware that encrypts files to locker ransomware that locks users out of their systems.

The Current Landscape: 2020s

Today, ransomware is a major cybersecurity threat affecting both individuals and large organizations. The attacks are more frequent, more sophisticated, and more damaging than ever. The impact is not just financial but also operational, often bringing critical services to a halt.


From its humble beginnings in the late 1980s to its current status as one of the most significant cybersecurity threats, ransomware has undergone a dramatic evolution. What started as a relatively simple form of malware has morphed into a complex and highly specialized form of cyberattack. As we navigate the digital landscape of the 2020s, understanding this evolution is crucial for both individuals and organizations looking to safeguard their data. For readers interested in more in-depth articles on cybersecurity topics, visit our Blogs page.


Strategies to Protect Your Data

A Safety Net in Crisis

Data backups serve as a critical layer of security, acting as a safety net when ransomware strikes. They allow you to restore your data without succumbing to the demands of cybercriminals, ensuring that you’re not left in the lurch.

The Best Offence is a Good Defence

The ability to restore data from clean backups is your best defence against ransomware. Paying a ransom is a risky move, as there’s no guarantee that your data will be restored. Hence, having a backup is not just a good practice; it’s a necessity.

Mitigating Data Theft

In an alarming trend, ransomware attackers are not just locking up your data; they’re stealing it. Threats of disclosing or selling sensitive data are becoming common. Backups can mitigate the impact of such threats, providing an extra layer of security.


Crafting a Robust Data Backup Strategy

The 3-2-1 Rule

The 3-2-1 backup strategy is a golden rule in data management. It involves having three total copies of your data: two local copies on different devices and one off-site. This approach ensures that you’re not putting all your eggs in one basket.

Versioning is Key

Keeping multiple versions of your backups is crucial. It ensures that you can restore your system to a point before the ransomware infection, providing a comprehensive safety net.

Frequency Matters

The frequency of your backups should be tailored to your needs. Consider how often your data changes and how critical it is to your operations. Frequent backups are a must for dynamic and critical data.

Embrace the Cloud

Cloud backups offer an additional layer of security and are generally easier to restore. They’re especially useful for organizations with complex IT operations, providing flexibility in what data to back up and how long to store it.
