📌 Supply Chain Attack Summary

A supply chain attack is when a cybercriminal targets a business by exploiting weaknesses in its suppliers or service providers. Instead of attacking the business directly, the attacker compromises software, hardware, or services that the business relies on. This type of attack can have wide-reaching effects, as it may impact many organisations using the same supplier.

🙋🏻‍♂️ Explain Supply Chain Attack Simply

Imagine you order a pizza, but someone tampers with the ingredients before they reach the pizzeria. Even if the pizzeria does everything right, your pizza could still be unsafe. A supply chain attack works in a similar way, where attackers target the sources rather than the final destination.

📅 How Can it be used?

Monitor and verify third-party software and hardware components before integrating them into your project to minimise supply chain attack risks.

🗺️ Real World Examples

In 2020, attackers compromised SolarWinds, a company providing IT management software. They inserted malicious code into software updates, which were unwittingly installed by thousands of organisations, including government agencies and large corporations.

Attackers once targeted a point-of-sale software vendor used by many retailers. By compromising the vendor’s update system, the attackers distributed malware to numerous shops, enabling them to steal customers’ payment information.

✅ FAQ

A supply chain attack happens when cybercriminals target a business by compromising the products or services it relies on, like software updates or hardware components from suppliers. This can be especially worrying because even if a company has strong defences, a weakness in an outside supplier can put it at risk. The effects can spread widely, impacting many organisations that use the same supplier.

Supply chain attacks can disrupt daily operations, leak sensitive data, or even spread malicious software across many businesses at once. Because organisations often depend on the same suppliers and service providers, a single attack can cause problems for many companies, not just the original target.

Companies can reduce risk by carefully choosing trusted suppliers, regularly checking for security updates, and keeping an eye on the security practices of their partners. It is also important to have plans in place to respond quickly if something unusual is detected, so any damage can be limited.

💡Other Useful Knowledge Cards

Neural Activation Sparsity

Neural activation sparsity refers to the idea that, within a neural network, only a small number of neurons are active or produce significant outputs for a given input. This means that most neurons remain inactive or have very low activity at any one time. Sparsity can help make neural networks more efficient and can improve their ability to generalise to new data.

Automated Feedback Collection

Automated feedback collection is the process of using technology to gather opinions, ratings or suggestions from users or customers without manual effort. This can involve online forms, chatbots, emails, or embedded surveys that automatically prompt users for their thoughts. The collected feedback is then organised and analysed to help improve products, services, or experiences.

AI for Indigenous Languages

AI for Indigenous Languages refers to the use of artificial intelligence tools and methods to support, preserve, and revitalise languages spoken by Indigenous communities. This can include creating tools for translation, speech recognition, text-to-speech, or language learning resources. The goal is to make these languages more accessible and usable in digital contexts, helping to keep them alive for future generations.

Skills Gap Analysis

A skills gap analysis is a process used to identify the difference between the skills employees currently have and the skills needed to perform their jobs effectively. By comparing current abilities with required skills, organisations can spot areas where training or hiring is required. This analysis helps businesses plan their staff development and recruitment strategies to meet future goals.

Forecast Variance Engine

A Forecast Variance Engine is a tool or system that analyses the differences between predicted outcomes and actual results. It helps organisations understand where and why their forecasts, such as sales or budgets, differed from reality. By identifying these discrepancies, teams can adjust their forecasting methods and make better decisions in the future.
