Navigating New Cyber Threats: The Shift from Third-Party Vendors to U.S. Tariffs in Supply Chain Security
Apr 16, 2025
Artificial Intelligence / Software Security
Introduction
Cyber threats aimed at supply chains are becoming increasingly concerning for businesses across various sectors. As companies deepen their reliance on third-party vendors, cloud services, and global logistics, cybercriminals are seizing opportunities to exploit vulnerabilities in these interconnected systems. By first targeting a third-party vendor with unnoticed security flaws, attackers can establish a foothold, using these weaknesses to penetrate the networks of primary business partners. This allows them to move laterally through vital systems, ultimately accessing sensitive data, financial assets, intellectual property, or even operational controls. Recent high-profile incidents, such as the 2024 ransomware attack on Change Healthcare—one of the largest health payment processing firms—illustrate how attackers can disrupt supply chain operations and compromise millions of patients’ protected health information (PHI), stealing up to 6TB of data.

Cybersecurity researchers have identified several severe vulnerabilities within the Versa Concerto network security and SD-WAN orchestration platform. Exploitation of these flaws could potentially grant attackers control over vulnerable instances. Despite responsible disclosure on February 13, 2025, these issues remain unpatched, leading to a public announcement after the 90-day window expired. According to ProjectDiscovery researchers Harsh Jaiswal, Rahul Maini, and Parth Malhotra, “When combined, these vulnerabilities could enable an attacker to fully compromise both the application and the host system.” The vulnerabilities include:

The North Korean cyber threat group known as Lazarus has been observed changing its strategies and rapidly enhancing its tools within its ongoing DeathNote campaign. While historically focused on the cryptocurrency sector, recent attacks have also expanded to include the automotive, academic, and defense sectors in Eastern Europe and beyond. This shift is seen as a major change in approach. Kaspersky researcher Seongsu Park noted that the group has switched its decoy documents to job descriptions for defense contractors and diplomatic services, marking a strategic pivot that began in April 2020. This campaign is also identified by other names such as Operation Dream Job or NukeSped, with Google-owned Mandiant linking certain activities to this evolving threat.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has categorized a significant security flaw affecting SonicWall Secure Mobile Access (SMA) 100 Series gateways as a Known Exploited Vulnerability (KEV) due to ongoing active exploitation. This high-severity vulnerability, identified as CVE-2021-20035 (CVSS score: 7.2), involves an operating system command injection that may allow for unauthorized code execution.
According to SonicWall’s advisory from September 2021, “improper neutralization of special elements in the SMA100 management interface permits a remote authenticated attacker to inject arbitrary commands as a ‘nobody’ user, potentially leading to code execution.”
The vulnerability impacts the following models: SMA 200, SMA 210, SMA 400, SMA 410, and SMA 500v (ESX, KVM, AWS, Azure) running specific versions—10.2.1.0-17sv and earlier (patched in 10.2.1.1-19sv and higher), 10.2.0.7-34sv and earlier (patched in 10.2.0.8-37sv and higher), and 9.0…

A critical privilege escalation flaw has been identified in Windows Server 2025, allowing attackers to compromise any user within Active Directory (AD). According to Akamai security researcher Yuval Gordon, the vulnerability exploits the Delegated Managed Service Account (dMSA) feature introduced in Windows Server 2025. This attack can be executed easily with the default configuration, posing a significant threat to organizations relying on AD. “In 91% of the environments we examined, users outside of the domain admin group possessed the necessary permissions to carry out this attack,” Gordon noted in a report shared with The Hacker News. The vulnerability takes advantage of the dMSA feature designed to facilitate migration from legacy service accounts and intended to mitigate Kerberoasting attacks. The attack technique has been dubbed “BadSuccessor” by the researchers.
