With cyber threats becoming increasingly sophisticated, it's crucial to stay ahead of new tactics used by cybercriminals. One emerging method is the supply chain attack. But what are supply chain attacks? A supply chain attack involves a hacker infiltrating your system through an outside partner or service provider with access to your systems and data. This blog post will provide a deep dive into this rising frontier in cybersecurity.

What are Supply Chain Attacks?

A supply chain attack, also known as a value-chain or third-party attack, involves exploiting vulnerabilities in the supply chain network. This complex process is performed to compromise a target system or information. In the world of IT, the supply chain represents all processes involved in the production and delivery of software products, starting from sourcing materials to software creation, transportation, and subsequent delivery to the end client. A weakness or vulnerability in any stage of this chain can be exploited by hackers, affecting numerous users at once.

How Do Supply Chain Attacks Work?

With supply chain attacks, a cybercriminal doesn’t target the final destination of a deliverable. Instead, they infect one of the earlier stages in the supply chain. This could involve corrupting a product or installing a backdoor during the production stage. The product then continues along the supply chain, infecting each system it comes into contact with, and finally reaching the end user. This method allows attackers to infiltrate numerous systems using a single attack, as opposed to traditional methods where they target each system individually.

Notable Supply Chain Attacks

Several notable supply chain attacks have made headline news in recent years. In the infamous SolarWinds attack, hackers infiltrated the system of SolarWinds, a company that develops software for businesses to manage their networks, systems, and information technology infrastructure. Unbeknownst to the company and its clients, an update was compromised, and thousands of customers downloaded malicious software, leading to compromised systems.

Why are Supply Chain Attacks Successful?

What makes supply chain attacks so effective is their stealthy nature. They allow attackers to bypass the target’s defenses by entering through a weak link in the supply chain. The objective is to remain undetected for as long as possible, giving the attacker a broader, more prolonged window of opportunity to steal data or cause damage. Since these attacks take place upstream, protecting your systems becomes a daunting task. Reliable cybersecurity solutions need to account for these new threats and protect every part of the supply chain process.

Preventing Supply Chain Attacks

Preventing supply chain attacks comes down to enforcing strong, holistic security practices across the entire software supply chain. This involves heightened security measures at every level of the production and distribution process. Some practices include adopting a zero trust architecture, and conducting regular security audits of all components of the software supply chain. Additionally, the use of strong, regularly updated passwords, and two-factor authentication can offer protective barriers and minimize the chances of a successful attack.

Emerging Trends in Supply Chain Attacks

Supply chain attacks are expected to rise as hackers continue refining their methods. A new derivative, the Software Supply Chain Attack, targets open-source libraries and public code repositories that are commonly used by developers. Since these libraries are widely used, the potential for inflicting damage is massive. Early detection and patching vulnerabilities are vital to prevent these attacks, highlighting the need for constant monitoring and robust cybersecurity strategies.

In conclusion, understanding what are supply chain attacks and how they can impact organizations is pivotal in this technologically-driven era. As hackers constantly evolve their methods, we must stay one step ahead by constantly improving and adapting our security measures. Cybersecurity strategies must now involve securing the entire supply chain process, implementing zero trust architecture and conducting regular security audits to minimize the risk of such attacks.
