Understanding Ransomware
Ransomware is a type of malicious software (malware) that encrypts a victim’s files or locks them out of their system, making the data inaccessible until a ransom is paid. The attacker typically demands payment in cryptocurrency, such as Bitcoin, to ensure anonymity. Ransomware can spread through phishing emails, malicious downloads, or exploiting vulnerabilities in software and networks. This form of cyber attack can have devastating effects on businesses, leading to significant financial loss, operational disruption, and damage to reputation. Ransomware attackers often demand payment in cryptocurrency to avoid detection, making it difficult to trace and recover the funds. The rapid evolution of ransomware techniques poses an ever-growing threat, making it essential for
businesses, especially small and medium-sized enterprises (SMBs), to stay informed and prepared to combat these attacks effectively.
Being Prepared
For SMBs, the impact of a ransomware attack can be particularly severe due to limited resources and potentially less robust security measures compared to larger enterprises. Preparedness is critical to mitigating the risks associated with ransomware. This includes implementing comprehensive cybersecurity strategies, regular employee training, and maintaining up-to-date backups. Being prepared not only helps in preventing attacks but also ensures a swift and effective response in the event of an incident. By understanding the nature of ransomware and adopting proactive measures, SMBs can protect their operations, secure sensitive data, and maintain customer trust, ultimately safeguarding and reducing the risk from future security incidents.
How Ransomware Attacks Occur
Ransomware attacks often begin with a phishing email that contains a malicious attachment or a link to a compromised website. When the victim opens the attachment or clicks the link, the ransomware is downloaded and executed on their system. Once activated, the ransomware encrypts files on the infected system and sometimes spreads to other connected devices and networks. The victim is then presented with a ransom note, demanding payment to decrypt the files or regain access to their system.

The victim is then presented with a ransom note, demanding payment to decrypt the files or regain access to their system.
Crypto Ransomware
This type encrypts files on a victim’s system, making them inaccessible. The attacker then demands a ransom for the decryption key. Examples include CryptoLocker and WannaCry.
Locker Ransomware
Instead of encrypting files, locker ransomware locks the victim out of their system, preventing access to applications and data. The attacker demands a ransom to unlock the system. Examples include WinLocker and Reveton.
Scareware
This type of ransomware pretends to be legitimate software or security alert, claiming that the victim’s system is infected with malware. The attacker demands payment to ‘remove’ the fake threat. Examples include FakeAV and Rogue.
RaaS (Ransomware as a Service)
This model involves ransomware developers providing their malicious software to affiliates, who then distribute the ransomware and share the profits with the developers. Examples include GandCrab and DarkSide.
How Ransomware Spreads
Ransomware spreads through several common methods, each designed to exploit vulnerabilities in human behavior or computer systems.
One prevalent method is phishing emails, where cybercriminals send deceptive messages that appear to be from trusted sources. These emails often contain malicious attachments or links that, when opened, download ransomware onto the victim’s device. Another common vector is malicious websites. These sites, either designed by attackers or compromised legitimate sites, host malicious code that can automatically download ransomware when visited. Users can inadvertently access these sites through misleading ads or links. Additionally, exploit kits are automated tools used by attackers to scan for and exploit known vulnerabilities in software and systems. Once a vulnerability is found, the exploit kit delivers the ransomware payload.
Regular software updates, user education, and robust security measures can help protect against these methods of ransomware spreading.
Ransomware Spreads by these 3 common methods.
Phishing Emails
Phishing emails are deceptive messages designed to trick recipients into revealing sensitive information or downloading malicious software. They often mimic trusted sources like banks or colleagues and may contain urgent requests or enticing offers. Common features include fake website links and malicious attachments.
Malicious Websites
Malicious websites are sites created or compromised by cybercriminals to spread malware or steal sensitive information. These websites can appear legitimate and may be linked from phishing emails, social media, or ads. When an unsuspecting user visits a malicious website, it can automatically download malware onto their device, exploit browser vulnerabilities, or trick them into entering personal information.
Exploit Kits
Exploit kits are automated tools used by cybercriminals to scan for and exploit vulnerabilities in software and systems. These kits are often embedded in malicious websites and can deliver ransomware payloads once a vulnerability is detected. Exploit kits target unpatched software, outdated browsers, and insecure plugins, taking advantage of known security flaws to execute their malicious code.
Understanding the Financial and Legal Impact from a Data Breach
Around 40% of all cyber breaches impact businesses with fewer than 100 employees.
Data breaches can lead to significant regulatory fines and customer lawsuits, posing severe financial and legal challenges for small and medium-sized businesses (SMBs). Recent examples illustrate these consequences vividly. In 2023, Bosley Inc., a hair restoration company, settled for $500,000 following a 2020 data breach that compromised customer information due to inadequate cybersecurity measures. Plaintiffs claimed that Bosley failed to protect their data and delayed informing customers about the breach, resulting in risks of fraud and identity theft. Customers had to invest time and resources to safeguard themselves, highlighting the importance of timely and effective breach management.
Similarly, Herff Jones, a graduation product manufacturer, faced a $4.35 million settlement in January 2023 after a data breach exposed customer payment card information in mid-2022. The class action lawsuit against Herff Jones argued that the company neglected reasonable data protection measures, leading to the breach. Although the company did not admit to any wrongdoing, it agreed to the substantial settlement to resolve the lawsuit, emphasizing the costly repercussions of data protection failures.
Accellion and San Juan Regional Medical Center also encountered significant settlements due to data breaches. Accellion settled for $8.1 million in early 2024 for a breach that affected millions in 2020, attributed to insufficient security measures. San Juan Regional Medical Center in New Mexico faced a class action lawsuit after a 2020 breach exposed nearly 69,000 patients’ private information. The settlement included two years of complimentary credit monitoring and identity theft protection services, with additional compensation for affected individuals.
Most cybersecurity incidents at SMBs cost between $826 and $653,587.
