The Rise of Ransomware Attacks

Ransomware assaults have become a common and extremely profitable kind of cybercrime in recent years, posing a substantial threat to organisations, individuals, and even governments all around the world. Ransomware is a sort of malicious software that encrypts data or systems on a victim’s computer or network, making them unavailable until the cybercriminals are paid a ransom. With the rising reliance on digital technology and the increasing value of data, fraudsters have turned to ransomware assaults to extort money from their victims. In this essay, we will look at the rise of ransomware attacks, how cybercriminals benefit from businesses and individuals, and how these assaults affect our society.


Ransomware assaults have been around since the late 1980s, but they have changed dramatically over the years to become more sophisticated and profitable. The first known ransomware assault, dubbed the “AIDS Trojan,” was found in 1989 and was primitive in comparison to modern ransomware. It propagated by infected floppy discs and displayed a message saying that the victim’s files had been encrypted and could only be decrypted by sending a payment to a Panama P.O. box. The ransom was little, and the attack was limited in scope, but it signalled the beginning of a new form of cyber threat.

Ransomware attacks have become more complex over time, extorting money from victims by utilising advanced encryption techniques, social engineering tactics, and anonymous payment mechanisms such as Bitcoin. Ransomware attacks are now highly organised and frequently carried out by professional cybercriminal organisations with advanced tools, strategies, and resources. Individuals, small and medium-sized businesses (SMBs), large firms, healthcare organisations, educational institutions, government agencies, and even vital infrastructure are all targets for these groups.


Ransomware assaults often follow a similar pattern, while methods and strategies utilised by various cybercriminal gangs may change. A high-level description of the typical mechanisms of a ransomware assault follows:

  1. INITIAL INFECTION: Ransomware generally infiltrates a victim’s system via phishing emails, malvertisements (malicious advertisement), exploit kits, drive-by downloads, or social engineering attacks. Once infected, the ransomware begins to spread laterally across the victim’s network, encrypting as many files and computers as possible.
  2. FILE ENCRYPTION: Once the ransomware has gained access to the victim’s files, it encrypts them with strong encryption techniques, rendering them unreadable without a decryption key. The victim is then shown a ransom note, which usually takes the shape of a pop-up window or a text file and offers instructions on how to pay the ransom and acquire the decryption key.
  3. RANSOM DEMAND: The ransom message will normally include the ransom amount, payment instructions, and a payment date. Depending on the target and the perceived value of the material, the ransom cost might range from a few hundred dollars to millions of dollars. Payment is typically requested in the form of cryptocurrency, such as Bitcoin, which provides a high level of anonymity.
  4. EXTORTION STRATEGIES: Cybercriminals frequently use various extortion strategies to raise the pressure on the victim to pay the ransom. Threatening to delete or publish the victim’s data if the ransom is not paid, setting deadlines with growing ransom amounts, or even contacting the victim’s customers or partners to publicise the breach and harm the victim’s reputation are all examples of such tactics.
  5. DECRYPTION KEY: Once the ransom has been paid, the cybercriminals may give the victim with a decryption key or programme to unlock the encrypted files. However, there is no guarantee that the decryption key will be delivered or that all of the files will be successfully decrypted. In certain circumstances, victims pay the ransom but do not receive the decryption key, or the operation fails.


Ransomware attacks can have severe and far-reaching consequences for businesses, individuals, and society as a whole. The financial impact of ransomware attacks is often significant, with cybercriminals demanding hefty ransoms that can range from thousands to millions of dollars. Businesses, especially SMBs, may struggle to afford such payments, leading to financial losses, reputational damage, and even bankruptcy. Additionally, the costs associated with investigating and remediating the attack, as well as implementing stronger security measures, can further strain the resources of affected organizations.

Beyond the financial impact, ransomware attacks can disrupt critical business operations, leading to loss of productivity, customer trust, and competitive advantage. For example, ransomware attacks against healthcare organizations can disrupt patient care, potentially endangering lives. Attacks against government agencies can compromise sensitive data and disrupt essential services, affecting citizens’ trust and confidence in their government. Ransomware attacks against individuals can result in personal data loss, identity theft, and emotional distress.

Ransomware attacks also highlight the ethical dilemma of paying ransoms to cybercriminals. While some victims may feel compelled to pay the ransom to regain access to their encrypted data, this can potentially fuel the ransomware economy and incentivize cybercriminals to continue their malicious activities. Moreover, paying the ransom offers no guarantee that the cybercriminals will honour their promise and provide the decryption key. It also encourages the use of ransomware as a profitable business model for cybercriminals, leading to more attacks and increased sophistication.

Furthermore, ransomware attacks can have broader societal implications. They can undermine trust in digital technologies and the ability to protect data, leading to a loss of confidence in online transactions and communication. They can also highlight the vulnerabilities in critical infrastructure, such as transportation systems, energy grids, and healthcare facilities, potentially posing risks to public safety and national security. The increasing interconnectedness of our digital world amplifies the potential impact of ransomware attacks, making them a significant concern for society as a whole.


Several factors have contributed to the rise of ransomware attacks as a preferred method for cybercriminals to exploit businesses and individuals for profit:

  1. Financial Motives: Ransomware attacks are financially motivated, with cybercriminals seeking to extort money from victims in exchange for the decryption key. The potential for significant financial gain, especially with the use of cryptocurrencies that offer anonymity, has made ransomware attacks attractive to cybercriminals.
  2. Ease of Deployment: Ransomware is relatively easy to deploy compared to other forms of cyber-attacks. Cybercriminals can purchase ransomware-as-a-service (RaaS) from the dark web, which provides them with pre-built ransomware kits that can be customized and used with minimal technical expertise. This has lowered the barrier to entry for cybercriminals, enabling them to carry out ransomware attacks on a large scale.
  3. Exploitation of Vulnerabilities: Ransomware attacks often exploit vulnerabilities in software, hardware, or human behaviours. Cybercriminals take advantage of unpatched systems, weak passwords, lack of employee awareness, and other vulnerabilities to gain unauthorized access and deploy ransomware.
  4. Increasing Value of Data: With the proliferation of digital data and the increasing reliance on it for business operations, the value of data has skyrocketed. Cybercriminals recognize this value and use ransom


One notable ransomware attack that had significant consequences was the “WannaCry” attack that occurred in May 2017. This attack targeted Windows-based systems and quickly spread to over 150 countries, affecting businesses, government organizations, and individuals alike.

The WannaCry attack exploited a vulnerability in Microsoft Windows operating systems, known as Eternal Blue, which had been previously leaked by the hacking group called “Shadow Brokers.” The ransomware encrypted files on infected systems and demanded a ransom in Bitcoin for their release. The attack demanded a ransom of $300 per infected system, with the amount doubling if not paid within a certain timeframe.

The impact of the WannaCry attack was widespread and severe. It caused widespread disruption to critical infrastructure, including healthcare systems, transportation networks, and government agencies. In the United Kingdom, the National Health Service (NHS) was particularly hard hit, with over 200,000 appointments and operations cancelled, and patient data inaccessible. This resulted in delays in patient care, and in some cases, patients being turned away from hospitals. The attack also affected major companies such as FedEx, Telefonica, and Renault, disrupting their operations and causing financial losses.

The WannaCry attack highlighted the vulnerabilities in outdated and unpatched systems, as the attack exploited a known vulnerability for which a patch had been released by Microsoft months before the attack. Many affected organizations had not implemented the necessary security updates, leaving their systems exposed to the attack.

The global economic impact of the WannaCry attack was estimated to be in the billions of dollars, including the cost of ransom payments, lost productivity, IT recovery efforts, and reputational damage. It also raised concerns about the potential for cybercriminals to disrupt critical infrastructure and essential services, and the need for organizations to prioritize cybersecurity measures to prevent and mitigate such attacks.

In response to the WannaCry attack, governments, organizations, and cybersecurity experts around the world took urgent steps to contain the attack, develop and implement security patches, and raise awareness about the importance of regular system updates and robust cybersecurity measures. It also highlighted the need for organizations to have robust data backup and recovery plans in place, as paying the ransom is not always a guaranteed solution and can further incentivize cybercriminals to continue their malicious activities.

The WannaCry attack served as a wake-up call for the global cybersecurity community and underscored the evolving and escalating threat posed by ransomware attacks. It highlighted the need for continuous vigilance, proactive security measures, and regular patching and updates to protect against such attacks and mitigate their potential impact. It also emphasized the importance of cybersecurity awareness and education among employees and individuals to prevent falling victim to ransomware attacks and other forms of cyber threats.


One recent example of a ransomware attack is the attack on the Colonial Pipeline in May 2021, which is one of the largest fuel pipeline operators in the United States. The attack disrupted the operations of the pipeline, which supplies fuel to the East Coast of the United States, resulting in fuel shortages and price increases in some regions. The attackers, reportedly affiliated with the Dark Side ransomware group, demanded a ransom payment in Bitcoin to restore access to the encrypted data and systems. The incident caused widespread concern about the vulnerabilities of critical infrastructure to cyber-attacks and highlighted the potential impact of ransomware attacks on essential services and the economy.

Another recent ransomware attack is the attack on the software company Kaseya in July 2021. Kaseya provides IT management and remote monitoring services to businesses, and the attack affected its VSA software, which is widely used by managed service providers (MSPs) to manage and monitor their clients’ IT systems. The attack resulted in the encryption of data on the systems of numerous Kaseya’s clients, including small and medium-sized businesses. The attackers, allegedly belonging to the REvil ransomware group, demanded a multi-million-dollar ransom payment in Bitcoin for the release of the encrypted data.

These are just a few examples of the numerous ransomware attacks that have occurred in recent years. Ransomware attacks continue to evolve in sophistication and are often carried out by organized cybercriminal groups or nation-state actors, targeting businesses, government organizations, healthcare providers, and individuals alike. The impact of ransomware attacks can be severe, resulting in financial losses, operational disruptions, reputational damage, and potential legal and regulatory consequences.
