Ready to prevent a Supply Chain Attack?

A top 10 (email) security threat, Supply Chain Attacks (SCA) have increased dramatically in recent years. They should be taken seriously as they result in severe damage to the entire supply chain network. In this type of attack, also known as a backdoor breach, value chain or third-party attack, cybercriminals penetrate an organization’s system through trusted suppliers, partners or vendors that have been whitelisted by the organization to facilitate data sharing and communication. The targets are usually technology vendors, managed service providers, or suppliers that have vulnerabilities in their security.

The mechanisms of Supply Chain Attacks

These are the most common scenarios of SCA:

  • Email-based Supply Chain Attacks – Companies often whitelist their trusted partners to facilitate communication. However, the whitelist can pose a vulnerability. Because if one of the partners is breached, hackers can easily penetrate the company through this loosened control and spread their malicious code.
  • Compromising software or updates – Criminals hack a vendor and insert malware into their software or compromise network protocols. When a customer buys and installs this software or its update, their entire system becomes infected. Open-source software solutions are particularly vulnerable to this type of attack, as hackers often build in vulnerabilities to later sneak malicious code into the companies using the software.
  • Stealing code-sign certificates – By stealing certificates that guarantee a product’s legitimacy and security, criminals can spread malicious code under the identity of the vendor.
  • Infected hardware – Malware is already pre-installed on hardware, devices or firmware components.
  • Foreign-sourced threats – Almost half of the Supply Chain Attacks come from state-sponsored groups from abroad. In particular, software/ hardware from China often contains malicious code that the manufacturer has integrated into its product at the government’s request.

Why are Supply Chain Attacks so dangerous:

  • Multiple targets with one attack – SCA can infiltrate an entire eco-system and spread beyond. Through the security weaknesses of one company, all other companies on its network can be infected, resulting in a large number of victims.
  • Difficult to detect – Due to the complexity of supply chains and access agreements, SCA can go undetected. No matter how good a company’s security is, hackers can bypass it through the privileged access granted to trusted suppliers.
  • Supply Chain Attacks are sophisticated – Most organizations do not have the expertise or resources to effectively prevent SCA. As a result, the malicious code can remain unnoticed for a very long time.
  • Supply Chain Attacks deliver various types of malware – SCAs most often involve phishing tactics, viruses, or other malicious software that spreads throughout the enterprise network.
  • Damage to image and business relationships – Becoming the source of multiple security breaches can harm the trust your partners have in your company. More and more organizations are evaluating their partners based on their security maturity. If they deem it insufficient, they demand upgrades or discontinue the relationship with the partner.

Supply Chain Attacks on the rise

Enterprise Security Practices for Exchange and Office365

he last couple of years, and especially 2021, have been marked by several huge attacks on service providers and vendors. Some of the most notable ones are the attacks on SolarWinds, Mimecast and Kaseya. Year 2021 has been extremely productive for supply chain attackers – over 66% of the confirmed attacks for the last 2 years were executed in 2021, which is a 100% growth compared to 2020.

In Wikipedia you will find the following definition of a supply chain attack: “a cyber-attack that seeks to damage an organization by targeting less-secure elements in the supply chain.” This formulation is a bit general, so let’s try to put it more precisely.
