Supply Chain Attack: A Modern Cybersecurity Challenge

In recent years, cybersecurity has become a major concern for businesses and individuals alike. The increasing reliance on digital technologies has created new vulnerabilities that hackers can exploit. To that end, attackers have come up with new strategies to breach a network, and supply chain attacks are among the most effective. In this article, we will explore what supply chain attacks are, their impact on businesses, and how organizations can protect themselves against them.

What is a supply chain attack?

A supply chain attack is a type of cyberattack that targets a company's suppliers or partners. The objective of a supply chain attack is to gain access to the target company's network through the vulnerabilities in supplier systems. Cybercriminals use this approach to bypass complex security measures and infiltrate an organization's infrastructure with malicious software or malware.

Supply chain attacks can occur anywhere in the supply chain, from the initial manufacturer to the end retailer. These attacks have become popular for two main reasons. Firstly, as business operations become more complex and more dependent on technology, companies find themselves outsourcing vital services to third-party providers. Secondly, cybercriminals see supply chain attacks as a low-risk and high-reward option since once access is gained, they can move laterally across the network undetected and cause damage or steal sensitive data.

Real-world examples of supply chain attacks

Recent supply chain attacks have shown the devastating impact they can have on businesses. Here are some real-world examples of the most notable supply chain attacks:

SolarWinds – In December 2020, SolarWinds, a Texas-based software company, discovered a supply chain attack that had infected its Orion IT management software. The malware, later named Sunburst, was concealed in a software update that was automatically downloaded by more than 18,000 SolarWind customers. The attacker gained access to sensitive data in government agencies and tech enterprises around the globe.

Kaseya – In July 2021, cybercriminals used a vulnerability in the software of Kaseya, an IT software company, to deploy ransomware to over 1,500 companies worldwide. The attackers demanded a ransom of $70 million in return for the decryption keys. The sophistication of the attack indicates that the hackers had extensive knowledge of the company's operations.

Microsoft Exchange Server – In March 2021, attackers exploited four zero-day vulnerabilities in Microsoft Exchange Server software, which is used by many businesses for their email services. The vulnerabilities allowed attackers to access email accounts and sensitive data. The attack, believed to be from China, affected thousands of businesses worldwide.

The impact of supply chain attacks on businesses

Supply chain attacks are becoming more frequent and severe each year. According to a survey by the Ponemon Institute, more than 60% of businesses experienced a supply chain attack in 2020, and the number is growing. Supply chain attacks can have a significant impact on businesses. A successful attack can result in:

Data breaches – Supply chain attacks offer cybercriminals access to the sensitive data of businesses, including customer data and intellectual property. The attackers can then use this data for fraud or sell it on the dark web.

Ransomware – Attackers can use ransomware to encrypt a company's data, demand a ransom, and threaten to delete or publish it if the ransom is not paid.

Lost revenue – A supply chain attack can cause downtime, which can result in lost revenue and reputational damage.

Compliance violations – Businesses are often required by regulation to maintain data privacy and security. A supply chain attack can result in the business being found in breach of these regulations.

How to prevent supply chain attacks

Preventing supply chain attacks is challenging, but there are several steps that businesses can take to reduce the risks. Some of these include:

Conducting due diligence on suppliers – Businesses need to verify their suppliers' cybersecurity protocols to ensure that they are secure. This includes conducting security audits, regular assessments, and checking their compliance with regulations.

Implementing multi-factor authentication – Multi-factor authentication provides an extra layer of security by requiring users to provide additional verification to access the network.

Regular security patching – Regular security patching of hardware, software and regular software upgrades to maintain the integrity of technology use.


Supply chain attacks are a growing concern for businesses worldwide. These cyber threats have the potential to cause significant harm to a company, including data breaches, lost revenue, and reputational damage. Organizations must acknowledge the risks posed by supply chain attacks and take the necessary steps to protect themselves. Implementing cybersecurity measures such as regular security patching, multi-factor authentication, and conducting due diligence on suppliers can help reduce the risks and prevent a devastating supply chain attack.

Data breaches have become a prominent issue in recent times, affecting individuals, businesses of all sizes, and even governments. Every time we input our personal information online, we take a risk of it being compromised. In this article, we will delve into what a data breach is, examples of breaches from large corporations, and tips to protect oneself from the potential risks of a data breach.

So, what is a data breach? A data breach occurs when sensitive and confidential information is accessed without authorization. This can happen when someone gains access to it accidentally or intentionally. Information that is often targeted includes credit card information, social security numbers, medical records, and anything that can be used to commit financial fraud. There are various ways data breaches happen, from cyberattacks to insider threats.

As cyber attackers become more sophisticated, a data breach can happen in various ways. The most common way is through phishing emails, whereby attackers pose as legitimate institutions and convince users to share their sensitive information. A phishing email may direct the recipient to click a dangerous link that can infect the system with malware or allow hackers to steal information.

Cyber attackers can also use malware, which can be downloaded on a user's computer when they visit illegal or unsecured websites, like those streaming movies or television shows. Malware can give hackers access to stored information on the user's computer or device. In some instances, hackers can also exploit vulnerabilities in software and gain access to an organization's systems, where they can extract valuable information. In many cases, hackers will use a combination of tactics to take down an organization's security.

Several big-name corporations have experienced significant data breaches. For instance, Equifax, one of the major credit reporting companies globally, suffered a data breach that exposed the personal and financial data of 143 million Americans in 2017. Hackers gained access to the company's servers through a software vulnerability, enabling them to lift consumer data that included social security numbers, names, birth dates, and addresses, among other sensitive details. The breach cost Equifax more than $1.4 billion in lawsuits and fines.

Another example is Target, which experienced a significant data breach in 2013 when attackers stole information from credit and debit cards used in its US stores. The breach affected 40 million credit and debit cards of Target's customers and 70 million records of personal data, including phone numbers and email addresses. Target suffered a significant hit to its reputation and paid $10 million in a class-action lawsuit.

To protect oneself from data breaches, there are some essential steps to take. Organizations should promptly patch their systems and software to avoid exploiting any known security vulnerabilities. Business owners should continually update their security measures, including their firewall, antivirus software, and intrusion detection systems.

Individuals can protect themselves by creating strong passwords, verifying the security of websites they input their personal information, installing reliable antivirus software, and being wary of emails or websites that ask for personal information.

These fraudulent methods have become prevalent, and they have left a trail of destruction in their wake. In this article, we will examine what a phishing attack is, how it is done, and tips on how you can prevent such attacks from happening to you.

What is a phishing attack?

Phishing attacks are an online scam designed to steal your confidential information by impersonating a trusted authority or someone you know. It involves sending an email, message, or making a phone call, which appears legitimate but is actually from a malicious source aiming to deceive you into disclosing your personal data. The attackers use social engineering techniques to manipulate and influence the recipient's behavior, create a sense of urgency or a feeling of reward, and get the victim to reveal sensitive information freely.

How is a phishing attack done?

Phishing attacks are often carried out via email or social media, and they are quite sophisticated. Cybercriminals put a lot of effort into designing the message with a legitimate look and feel to manipulate the recipient. For example, a phishing email would include a sender's name that seems trustworthy, such as Apple Support, PayPal, or Netflix. The email will ask the user to update their login credentials or personal information by following a link.

The link often leads to a fake website that looks identical to the legitimate one. This could be anything from a login page for a bank account or a social media account to a shopping site. The phisher will then ask the victim to enter their username and password, which the hacker can use to access the victim's account and steal their data.

Another common tactic for phishing is through instant messaging services. An attacker will impersonate a friend or colleague, asking the recipient to send or download a particular document or file attachment. Once the victim downloads or opens the attachment, it installs malware, giving the hacker access to the victim's system.

How to prevent phishing attacks?

Prevention is the best method for combating phishing attacks. However, it is important to understand that if you fall prey to these attacks, it is not your fault. Attackers have become quite adept at crafting phishing schemes that can catch even the most vigilant of us. Here are some steps to follow to avoid falling victim to phishing attacks:

Always be wary of unsolicited emails, messages, or phone calls from unknown sources. Hackers use social engineering to create a sense of urgency or fear, making it seem like it is imperative to act immediately.

2) Don't click on links or download attachments from unknown sources:

If you receive an email with questionable content or links from unknown sources, do not click on them. You can hover your cursor over the link to see if it is legitimate. If it isn't, then delete the message immediately.

3) Check the sender's email address:

Hackers often impersonate legitimate companies by replicating their email addresses. Check the email address carefully and look for any misspellings or discrepancies.

4) Enable two-factor authentication:

Two-factor authentication can help you in securing your accounts. This means you will need to provide two types of information to access your account – typically a password and a unique code sent to your mobile phone or email.

5) Keep your software up to date:

Ensure that your devices, applications, and software are up to date with the latest security patches and updates. This reduces the likelihood of successful phishing attacks.

6) Educate yourself and your family:

Phishing attacks can happen to anyone. Therefore, it is essential to educate yourself and your family members about the possible threats of phishing attacks, including email scams, texts scams, and social media scams.

In conclusion, phishing attacks are a significant threat to online users, and everyone should arm themselves with the right knowledge to combat them effectively. If you follow the recommendations given above and stay vigilant, you can avoid falling victim to these scams. Always remember never to provide your personal details to anyone unless you are sure of their legitimacy. It is better to be sceptical of unfamiliar messages online, rather than risk being robbed of your hard-earned money.
