Supply Chain Attack
A supply chain attack is a type of cyber-attack that seeks to inflict damage on an organization by targeting less secure elements within its supply chain. This type of attack can occur across various industries, including the financial sector, the oil industry, and even in governmental sectors. Supply chain attacks can affect both software and hardware components.
Mechanism of Attack
The essence of a supply chain attack lies in its exploitation of the interconnectedness and interdependence of the supply chain elements. Cybercriminals may infiltrate these systems in numerous ways, such as:
-
Tampering with Manufacturing or Distribution: Attackers can embed malware or hardware-based spying components during the manufacturing or distribution stages of a product. This malware can be designed to go undetected until it reaches the intended target or user.
-
Software Supply Chain Attacks: Involves targeting the software supply chain, which includes components, libraries, and tools used in software development. A notable example is the compromise of Npm packages through phishing attacks on package maintainers. Attackers manipulate software updates to distribute malicious code.
Notable Incidents
SolarWinds Attack
One of the most significant supply chain attacks was the 2020 attack on SolarWinds. The attackers infiltrated SolarWinds' Orion software platform, which was used by numerous organizations worldwide, including several U.S. federal government agencies. This breach allowed attackers to gain undetected access to sensitive systems for several months.
ASUS Live Update Attack
In 2019, a large-scale attack known as ShadowHammer was uncovered by Kaspersky Lab. Attackers injected malicious code into official ASUS Live Update software, which was then distributed to unsuspecting users.
Implications and Preventive Measures
Supply chain attacks underscore the vulnerabilities present in interconnected systems. With a reported 78% increase in these attacks in 2018, as highlighted in Symantec's Internet Security Threat Report, organizations are urged to adopt comprehensive cybersecurity measures. These might include:
-
Rigorous Third-Party Assessments: Ensuring that all elements in the supply chain adhere to stringent cybersecurity standards.
-
Enhanced Software Audits and Code Reviews: Regularly auditing software components to detect and eliminate potential vulnerabilities.
-
Advanced Threat Detection Systems: Deploying sophisticated threat detection mechanisms to quickly identify and mitigate potential breaches.
