Ransomware has become one of the most significant cybersecurity threats that businesses and organizations face today.

Cybercriminals deploy these harmful attacks to lock down an organization’s data and systems by encryption, demanding a ransom in exchange for the decryption key.

Even in the best-case scenario, where you can swiftly recover from backups, the ordeal is stressful, no matter how prepared you are.

For this reason, it’s wise to operate under the assumption that it’s not a matter of if, but when, and plan accordingly.

As attacks grow more advanced and pervasive, it’s vital for businesses to implement a comprehensive strategy for ransomware prevention and recovery.

In this guide, as one of the leading web development companies in Kolkata with an ISO/IEC 27001:2022 certification, which is an international standard for information security management that helps organizations protect their data, we’ll outline the best practices for restoring your data and systems following an attack, along with proactive steps to reinforce your defenses against ransomware.

The Growing Ransomware Threat

The numbers tell a sobering story—ransomware attacks are becoming increasingly prevalent.

According to the 2023 Ransomware Market Report, global ransomware costs are projected to soar to $265 billion annually by 2031, a sharp rise from $20 billion in 2021.

After a brief dip in incidents and ransom payments in 2022, ransomware made a strong comeback in 2023.

Complaints surged to over 2,825, reflecting an 18% increase from the previous year. Payments also reached a staggering $1 billion, marking a 96% increase and the highest total recorded to date.

Additionally, Sophos’ State of Ransomware 2024 report revealed that 59% of organizations were hit by ransomware in the past year.

Cybercriminals are constantly refining their tactics. The FBI has observed new trends, including the use of multiple ransomware variants against the same victim and the implementation of data destruction techniques to heighten the pressure on victims to settle.

Ransomware by the Numbers

The ransomware landscape experienced significant shifts in ransom demand tactics, according to the Coveware Q1 2024 Quarterly Report.

In the first quarter of 2024, the average ransom payment continued its decline, dropping by 32% from Q4 2023 to $381,980.

However, the median ransom payment rose by 25%, reaching $250,000.

Coveware analysts attribute this disparity to fewer companies paying sky-high ransoms, which has contributed to the decrease in the average payment.

At the same time, many ransomware groups have adopted a strategy of setting more "reasonable" initial demands to encourage victims to engage in negotiations rather than being deterred by exorbitant sums.

This calculated shift toward more moderate ransom requests is designed to increase the chances of payment.

The Coveware report also sheds light on the widespread impact of ransomware across various industries.

Healthcare was the hardest hit, accounting for 18.7% of all attacks, with professional services following closely at 17.8%.

The public sector, which includes government agencies and educational institutions, was another significant target, making up 11.2% of incidents.

Other sectors notably affected include consumer services (10.3%), retail (5.6%), financial services, and food & staples retail, both at 4.7%.

This data highlights the pervasive nature of ransomware, which threatens industries ranging from critical sectors like healthcare to consumer and technology-driven businesses.

Even industries that are traditionally less digitized, such as materials (6.5%), capital goods (2.8%), and automobile manufacturing (3.7%), were not spared from attacks.

This trend emphasizes the importance of comprehensive cybersecurity strategies and ransomware preparedness, regardless of industry or digital reliance.

Ransomware continues to pose a major threat to businesses of all sizes, with small and medium-sized businesses (SMBs) being particularly vulnerable.

A striking 71.8% of affected companies had between 11 and 1,000 employees, underscoring that SMBs are a prime target for ransomware attacks.

While no organization is completely immune, the data reveals SMBs' susceptibility, likely due to their limited cybersecurity resources and smaller IT teams compared to large enterprises.

This emphasizes the urgent need for SMBs to prioritize ransomware preparedness and implement strong security measures tailored to the risks they face.

At the same time, ransomware groups are also targeting large corporations, with 1.9% of affected companies employing over 100,000 people.

This demonstrates that no sector or company, regardless of size, can afford to be complacent when it comes to the growing ransomware threat.

Ransomware as a Service (RaaS)

Ransomware as a Service (RaaS) has transformed the cybercrime landscape, significantly expanding the scale and impact of ransomware attacks.

This business model enables even inexperienced cybercriminals to easily access and deploy ransomware, resulting in a global increase in both the frequency and sophistication of these attacks.

In the past, carrying out a ransomware attack required substantial technical expertise and resources, limiting such operations to skilled hackers or organized cybercrime groups.

However, with the rise of RaaS platforms, the entry barrier has been dramatically lowered. These platforms offer ready-made ransomware kits that come equipped with user-friendly interfaces, detailed instructions, and even customer support.

Operating on a subscription or profit-sharing model, RaaS allows cybercriminals to distribute ransomware and split the resulting payments with the platform operators, making ransomware more accessible and profitable than ever before.

The rise of RaaS has triggered a surge in ransomware attacks, as cybercriminals leverage the anonymity of the dark web to collaborate, pool resources, and execute large-scale campaigns.

The RaaS model not only simplifies the distribution of ransomware but also equips criminals with analytics dashboards to monitor the performance of their attacks, allowing them to refine their tactics for greater financial gain.

Evolving Threats and Increasing Complexity

A major consequence of Ransomware as a Service (RaaS) is the rapid expansion in the number and diversity of ransomware strains.

RaaS platforms are constantly evolving, releasing new variants that make it increasingly difficult for cybersecurity professionals to create effective defenses.

These varied strains allow cybercriminals to target a wide range of industries, regions, and specific vulnerabilities, significantly increasing their chances of a successful attack.

The profitability of the RaaS model has drawn in a new wave of cybercriminals, creating an underground economy with specialized roles.

Ransomware developers produce and sell their malicious software on RaaS platforms, while affiliates or "distributors" handle the spread of ransomware through phishing emails, exploit kits, or compromised websites.

This division of labor enables criminals to focus on their areas of expertise, while RaaS operators manage the ransom collection process and take a cut of the profits.

The Commoditization of Ransomware

The rise of Ransomware as a Service (RaaS) has had far-reaching implications beyond the immediate financial and operational impacts on targeted organizations.

The easy availability of ransomware toolkits has led to a phenomenon known as "ransomware commoditization," where cybercriminals compete by offering their services at reduced prices, often engaging in price wars.

This competition drives innovation, ensuring that ransomware continues to evolve and remain a constant threat.

To counter the growing influence of RaaS, organizations and individuals must adopt a multilayered approach to cybersecurity.

This includes prioritizing regular data backups and establishing comprehensive incident response plans to enable swift recovery after an attack.

Testing backup restoration processes regularly is crucial for maintaining business continuity and minimizing damage from ransomware.

RaaS has reshaped the ransomware landscape by democratizing access to malicious tools, which has fueled the growth of cybercrime. Its ease of use, scalability, and profitability have led to a surge in ransomware attacks across various industries and regions.

By maintaining strong cybersecurity protocols and remaining vigilant, organizations can better safeguard themselves against the ever-evolving threats posed by RaaS and build resilience against potential ransomware incidents.

Understanding How Ransomware Works

A ransomware attack begins when malware infects a machine within your network. Cybercriminals use various techniques to deliver this malware, such as malicious email attachments, spam links, or more advanced social engineering tactics.

As users become more aware of these common attack methods, hackers continuously adapt their strategies.

Once the malicious file is executed on an endpoint, it quickly spreads across the network, encrypting files and locking them behind encryption that only the attackers can control.

There are several types of ransomware, beyond the traditional encryption model, including:

• Non-encrypting ransomware (lock screens): This type restricts access to files and data but does not encrypt them.
  
• Ransomware targeting the master boot record (MBR) or NTFS: These attacks prevent victims from booting up their computers in a normal operating system (OS) environment by encrypting critical areas of the drive.
  
• Leakware or extortionware: This variant steals sensitive data and threatens to release it publicly if the ransom is not paid. This form of ransomware is on the rise, with 91% of attacks in 2023 involving data exfiltration.
  
• Mobile device ransomware: Targeting cell phones, this ransomware spreads through drive-by downloads or fake apps, locking down mobile devices.
  

By understanding these different forms of ransomware, organizations can better prepare to defend against and respond to these evolving threats.

The Lifecycle of a Ransomware Attack

Cybercriminals have a variety of tools and methods at their disposal to infiltrate systems, conduct reconnaissance, and execute attacks.

In cybersecurity, these are referred to as tactics, techniques, and procedures (TTPs).

A typical ransomware attack follows this general lifecycle:

• Initial Compromise: The ransomware infiltrates the system using methods such as exploiting software vulnerabilities, phishing emails, brute-force attacks, or even physical media like USB drives.
  Once inside, it installs itself on a device, granting the attacker remote access.
  
• Secure Key Exchange: After installation, the ransomware connects to the attacker’s command and control server, which generates the cryptographic keys necessary to lock the system.
  
• Encryption: With the cryptographic lock in place, the ransomware begins encrypting files both locally and across the network, making them inaccessible without the decryption keys.
  
• Extortion: Once access is secured, the ransomware displays instructions, including the ransom amount, payment details, and the consequences of not complying with the demand.
  
• Recovery Options: At this stage, the victim has several choices: attempt to remove the ransomware, restore systems from clean backups, or consider paying the ransom. However, paying is strongly discouraged.
  According to Veeam’s 2024 Ransomware Trends Report, one in three organizations that paid the ransom could not recover their data.
  There’s no guarantee the decryption keys will work, and paying only encourages further attacks.
  

Understanding these stages can help organizations better prepare for and respond to ransomware incidents, minimizing the damage and ensuring a faster recovery.

Who Is Targeted by Ransomware?

Ransomware attacks affect businesses of all sizes, with no company—whether an SMB or a large corporation—truly safe from these threats.

Attacks are increasing across all sectors and business sizes, but small to medium-sized businesses (SMBs) are especially vulnerable.

Lacking the resources to fortify their cybersecurity defenses, SMBs are often seen by cybercriminals as "easy targets."

Recent incidents, such as cybercriminals leaking sensitive patient photos from medical facilities, highlight that no organization or industry is off-limits.

These attacks demonstrate the need for heightened precautions, particularly for organizations with outdated IT systems or weak security controls.

Ensuring that backup data is well protected should be a priority, as outdated or unprotected backups are prime targets.

According to Veeam’s report, backup repositories are targeted in 96% of ransomware attacks, and in 76% of cases, attackers successfully compromise the backups.
 

This statistic underscores the critical need to secure backups as part of a comprehensive defense strategy.

Geographically, the U.S. leads in ransomware attacks, followed by the U.K., Germany, Russia, and India.

While Windows systems are most frequently targeted, ransomware variants for Mac and Linux also exist, proving no operating system is entirely safe.

The reality is that ransomware has become so pervasive that most companies are likely to encounter it in some form.

The best course of action is to be prepared and to implement strategies that minimize the damage and speed up recovery when an attack occurs.

Steps to Combat Ransomware Attacks

If you've fallen victim to a ransomware attack, the next steps are crucial for mitigating the damage.

Depending on your industry and local regulations, you may need to report the breach immediately.

Once legal obligations are met, your focus should shift to controlling the damage.

Here's what to do next:

• Isolate the Infection: Quickly disconnect the infected device from your network and any shared storage to prevent the ransomware from spreading further.
  
• Identify the Ransomware: With countless strains of ransomware circulating, it's essential to identify which one you're dealing with. Scan messages and files, and use ransomware identification tools to better understand the specific threat.
  
• Report the Attack: While reporting requirements vary, it's always advisable to notify the appropriate authorities. Their support can aid in countering the attack and coordinating further actions.
  
• Evaluate Your Options: Assess the potential solutions for addressing the ransomware. Depending on your situation, consider which course of action is most appropriate, such as restoring systems or seeking external assistance.
  
• Restore and Rebuild: Use secure backups and trusted software sources to restore your systems. If necessary, consider setting up a new, clean system from scratch to ensure all traces of the ransomware are removed.

1. Isolate the Infection

When hit with ransomware, time is of the essence. Some strains spread rapidly from a single endpoint to entire networks, locking up data before containment is possible.
 

Even if you only suspect an infection, your immediate priority should be to isolate the affected machine from other devices and storage systems.

To do this, disconnect the infected machine from the network by disabling Wi-Fi, turning off Bluetooth, and unplugging any LAN or storage connections.

This action not only prevents the ransomware from spreading but also cuts off its ability to communicate with the attackers.

Be aware that you may be dealing with more than one "patient zero."

The ransomware may have infiltrated your system through multiple points of entry, especially if the attackers have monitored your patterns before launching the attack.

It could also be dormant on other devices.

Until you can verify, treat all connected systems as potentially infected.

2. Identify the Infection

While cybercriminals are behind ransomware attacks, there are resources available to help you combat them.

Websites like ID Ransomware and the No More Ransom! Project can assist in identifying the specific strain you're dealing with.

Understanding the type of ransomware affecting your system will provide insight into how it spreads, what files it typically targets, and what options you may have for removal or disinfection.

Reporting the attack to the authorities can also provide you with valuable information and support, so it's highly recommended to do so.

3. Report the Attack to Authorities

While it may be tempting to avoid reporting a ransomware attack to protect your business's reputation or to prevent potential disruptions during an investigation, reporting the incident is crucial.

Not only does it help in combating ransomware on a larger scale, but it also contributes to protecting other businesses from similar attacks in the future.

Each reported case provides authorities with valuable insights into the attackers, their methods, and how they infiltrated your system.

By reporting the attack, you play a vital role in helping law enforcement develop strategies to prevent future attacks and track down cybercriminals.

4. Evaluate Your Options

The good news is that you do have options after a ransomware attack. The bad news is that the most obvious choice—paying the ransom—is one of the worst.

While paying the ransom might seem like a quick fix, especially if the cost appears lower than the potential loss of productivity, this is exactly what cybercriminals are hoping for.

However, giving in to their demands only fuels further attacks, encouraging them to target other businesses or individuals.

Additionally, paying the ransom fosters a criminal ecosystem and can even result in civil penalties, with no guarantee that you'll recover your data.

Your better alternatives are to attempt removing the ransomware or rebuilding your system from secure backups.

5. Restore and Rebuild—or Start Fresh

There are several tools and resources, such as the No More Ransom! Project, that may help remove ransomware from your system.

Other software options are also available to assist in this process.

However, successfully and completely removing ransomware is not always guaranteed.

Not every strain has a working decryptor, and cybercriminals constantly evolve their methods—each time a solution is found, new ransomware is developed.

To ensure your system is secure, it's wise to either restore your system from clean backups or start fresh by rebuilding it entirely.

Why Restoring from Backups is the Safer Choice

The most reliable way to ensure ransomware is completely removed from your system is to wipe all storage devices and reinstall everything from scratch.

Formatting your hard drives guarantees that no trace of the ransomware remains, providing a fresh start.

To effectively address the ransomware, it's essential to pinpoint when the infection first occurred by analyzing file dates, messages, and other relevant clues.

Keep in mind that the ransomware may have been lying dormant before becoming active and making significant changes.

Understanding the specific strain that attacked your system will give you key insights into its behavior, helping you develop the best approach for restoring your systems to their full functionality.

When restoring your system, select a backup made prior to the initial ransomware infection.

If you've followed a solid backup strategy, you should have copies of your important documents, media, and files from just before the attack.

Utilize both local and off-site backups that were not connected to the network during the attack, ensuring they remain uninfected.

However, before fully restoring your systems, it's wise to use a secure quarantine environment to test the backup.

This precaution helps confirm that no dormant ransomware is present before bringing your production systems back online.

How Object Lock Safeguards Your Backups

Tools having object lock functionality (sold in the marketplace) provides an additional layer of protection for your backups by storing data in a write once, read many (WORM) model.

Once the data is written, it cannot be modified, ensuring that no one can encrypt, tamper with, or delete it for a specified period of time.

This creates a strong line of defense against ransomware attacks.

Object Lock serves as a virtual "air gap" for your data. Traditionally, in the world of LTO (Linear Tape Open) tape, backups were physically removed from the network after being written, creating a physical gap that protected the data from attacks.

In the event of a ransomware incident, those tapes could be used to restore systems.

Object Lock as a tool (sold in the marketplace) achieves the same protection in the cloud by virtually isolating your data, preventing unauthorized access or alterations without the need for physical removal.

Why a System Restore Isn’t Enough

While using a system restore point might seem like an easy fix to regain functionality after a ransomware attack, it is not a reliable method for completely removing the virus or ransomware responsible for the issue.

Malicious software often embeds itself deep within various system components, making it difficult for system restore to eliminate every trace of the infection.

Another key concern is that ransomware can also target and encrypt local backups. If your computer is compromised, there's a high chance that any local backup solutions will be affected as well, leaving them just as encrypted as the rest of your system.

By using a robust, isolated backup solution, you can safely retrieve the necessary files to restore your system.

This approach allows you the flexibility to select which files to restore from specific points in time, ensuring a more secure and thorough recovery process.

Human Attack Vectors: The Initial Compromise TTPs

In many cases, the weakest link in your security protocol is human error. Cybercriminals are well aware of this and exploit it through social engineering tactics.

Social engineering refers to the practice of manipulating individuals into revealing sensitive or confidential information, which can then be used to carry out fraudulent activities. 

Essentially, the most vulnerable part of your system is often the person using it.

Here are some common human attack vectors cybercriminals exploit:

1. Phishing

Phishing involves sending emails that appear to be legitimate in order to deceive recipients into clicking a malicious link or opening an infected attachment.

These emails can be sent to a single person or to multiple individuals within an organization. In some cases, cybercriminals invest time in researching their targets to make the emails more convincing.

This personalized approach, often aided by tools like generative AI models, makes the phishing attempt seem more credible.

Attackers may disguise the sender’s email address to mimic someone the recipient knows or craft a subject line that aligns with the victim's job responsibilities.

When this level of personalization is used, it's known as "spear phishing."

2. SMSishing

SMSishing, as the name suggests, uses text messages to deceive recipients into visiting malicious websites or entering personal information on their devices.

Attackers often pose as financial institutions or service providers, sending messages that appear to be legitimate, such as authentication requests or urgent alerts.

Some SMSishing variants are even more dangerous, as they attempt to spread by sending themselves to all contacts in the victim's device, further propagating the attack and increasing its reach.

3. Vishing

Vishing, similar to email and SMS phishing, uses voicemail to trick victims. The attacker leaves a message instructing the recipient to call a seemingly legitimate number, which is actually spoofed.

When the victim calls, they are manipulated into following steps that appear to resolve a problem but are, in fact, designed to install ransomware on their computer.

Vishing has become more advanced with the rise of AI, with deepfakes successfully mimicking the voices of company executives, leading to scams totaling as much as $25 million.

Like spear phishing, vishing has also become more targeted and personalized, making it increasingly dangerous.

4. Social Media

Social media can be a potent tool for cybercriminals to trick victims into taking compromising actions, such as downloading an image or file.

Malicious content, disguised as music, videos, or other interactive media, may carry ransomware or other malware.

Once the victim opens the file, their system becomes infected, allowing the attacker to gain access or control. Social media’s wide reach and perceived trustworthiness make it an effective platform for spreading malicious content.

5. Instant Messaging

Instant messaging platforms like WhatsApp, Facebook Messenger, Telegram, and Snapchat, with over four billion users combined, are a prime target for ransomware attacks.

Cybercriminals often send messages that appear to come from trusted contacts, containing links or attachments that, once opened, infect the device.

In some cases, the malware can spread across the victim’s contact list, further amplifying the attack and increasing its reach.

Machine Attack Vectors: Initial Compromise TTPs

Machine-to-machine attack vectors represent another method of ransomware infiltration. While humans may unintentionally initiate these attacks by visiting a website or using a device, the actual attack is automated and does not rely on direct human interaction to breach your computer or network.

Once triggered, these attacks proceed independently, compromising systems without the need for further human involvement.

Machine Attack Vectors: Common Methods of Ransomware Infiltration

1. Drive-by Attacks

Drive-by attacks are particularly dangerous because the victim only needs to visit a compromised website that hosts malware embedded in an image or active content. As the name suggests, simply "driving by" the site is enough to infect your system.

2. Exploiting Known System Vulnerabilities

Cybercriminals often exploit vulnerabilities in specific systems, especially those that haven't been patched with the latest security updates. These unpatched systems provide an easy entry point for attackers to install ransomware.

3. Malvertising

Malvertising operates similarly to drive-by attacks, but malware is delivered through online ads. These ads can be placed on search engines or popular social media platforms, reaching a large audience. Adult-only websites are a common host for malvertising campaigns.

4. Network Propagation

Once ransomware infects a system, it can search for file shares and accessible computers, spreading itself across the network. Companies with weak security may find their file servers and network shares compromised.
The ransomware continues to spread until it either runs out of accessible systems or encounters security defenses.

5. Propagation through Shared Services

Ransomware can also spread through online file sharing or syncing services. If an infected file enters a shared folder on a home device, it can propagate to an office network or other connected machines.
Many file-sharing services automatically sync when files are added or modified, allowing ransomware to spread rapidly across systems.

To mitigate these risks, it's crucial to manage your sync settings carefully and only share files with trusted sources.

Best Practices for Ransomware Prevention

Security experts recommend several key measures to help prevent ransomware attacks and safeguard your systems:

• Deploy Antivirus and Antimalware Solutions: Use trusted security software to block known ransomware payloads from executing. Ensure these tools are updated regularly to catch the latest threats.
  
• Regularly Backup Important Files: Create frequent and comprehensive backups of critical files, ensuring they are isolated from local and open networks. This helps in quickly restoring your system if an attack occurs.
  
• Utilize Immutable Backups: Consider options like Object Lock, which allows you to maintain air-gapped backups. These backups are immutable, meaning they cannot be changed or deleted for a set period, providing additional security.
  
• Store Offline Backups: Keep backup data stored in air-gapped or disconnected environments, such as external drives or cloud storage. This ensures ransomware cannot access or encrypt your backups.
  
• Stay Up-to-Date with Security Patches: Regularly update your operating systems, applications, browsers, and web plugins through trusted vendors. Patch vulnerabilities early and frequently to prevent exploitation.
  
• Use Endpoint and Network Security Software: Protect all endpoints, email servers, and network systems with security software that can detect and prevent ransomware infections.
  
• Network Segmentation: Isolate critical computers by segmenting your networks. This prevents ransomware from spreading if an attack does occur. Also, disable unnecessary network shares.
  
• Follow the Principle of Least Privilege: Restrict administrative rights to only those users who absolutely need them. Ensure employees have the minimum system permissions required for their tasks.
  
• Limit Write Permissions: Restrict write access on file servers as much as possible to reduce the risk of ransomware encrypting sensitive data.
  
• Educate Employees: Ensure that you and your staff are trained in best practices for avoiding ransomware. Keep everyone informed about the latest phishing scams and social engineering tactics that cybercriminals use to compromise systems.

So, Prevention Is The Best Cure!

As one of the leading web development companies in Kolkata with an ISO/IEC 27001:2022 certification, which is an international standard for information security management that helps organizations protect their data, we believe that the most effective way to handle ransomware is to prevent an attack altogether.

However, in the event of an attack, having backups that are isolated from the infection will minimize downtime and data loss.
