How a Compromised Third-Party Led to a National Security Incident
The recent hack of the U.S. Treasury Department, attributed to a Chinese state-sponsored hacking group, was facilitated through a vulnerability in the cybersecurity firm BeyondTrust. According to reports, the breach was first detected on December 8, 2024, when BeyondTrust, a provider of privileged access management solutions, notified the Treasury that a threat actor had gained access to a key used to secure a cloud-based service. This key was instrumental in providing remote technical support for the Treasury's departmental offices' end users, thereby allowing hackers to override security measures and access workstations. 1. 2. 3.
For the reasons discussed below Blacksands Cyber Zero Trust Technology would have prevented the hack.
Details of the Hack:
Method of Hack: The attackers exploited a compromised key from BeyondTrust, which was used for securing a cloud service. This breach allowed the hackers to remotely access certain workstations within the Treasury Department.
Impact: The information accessed was unclassified, but this incident has raised significant concerns regarding the security of sensitive government operations. There's no evidence suggesting ongoing access by the hackers to Treasury systems post-incident. 1.2.
Response: The Treasury has taken steps to mitigate the impact, including taking the affected BeyondTrust service offline and working with agencies like the FBI and the Cybersecurity and Infrastructure Security Agency (CISA) to assess the damage. Coverage of the hack is ongoing. 3. 4.
Risks with Poor Key Management:
Compromised Keys: The core of this incident was the theft of a security key. Poor management of cryptographic keys can lead to unauthorized access, as keys are central to authenticating and securing communications and data.
Human Error Multiplied: Often, breaches stem from human mistakes like misconfiguration or inadequate access controls, which can be exacerbated by a lack of robust key management practices. In environments where keys are not properly tracked, rotated, or revoked, the risk of widespread breaches increases, particularly when keys are used across multiple services or systems. 5.
Risks with Cloud-Based Managed Security:
Increased Attack Surface: Cloud environments inherently expand the attack surface. Misconfigurations in cloud setups can lead to data exposure or provide avenues for lateral movement within compromised networks.
Third-Party Vulnerabilities: When security is outsourced, the security posture of the third-party provider directly impacts the client. If a service like BeyondTrust is compromised, it can serve as a gateway to attack other connected systems.
Data Integrity and Trust: Cloud services must ensure that data remains confidential and unaltered, which requires stringent key management, especially in scenarios where keys control access to critical infrastructure. Relying on cloud services for government functions creates a dependency on external providers' security protocols, which, if breached, can compromise national security. 6.
This incident drives many organizations to even greater complexity and risk implementing:
A New Approach
Blacksands SDC can provide full control of every connection and the remove the risk of a stolen Key.
Blacksands Software Defined Connectivity offers a unique ‘Separation of Powers’ architecture which provides granular visibility (full story) and brokered point-to-point encrypted connections (full control) from the network layer (OSI Layer 3) to the application layer (OSI Layer 7). Each Blacksands’ connection requires multi-factor authentication prior to any brokering of said connection. Each Blacksands Receiver maintains ‘Invisibility’ (no communication) even if an adversary has obtained a legitimate key. This mitigates any access from a potentially stolen or compromised keys.
Instead of application layer (Layer 7) PKI (Public Key Infrastructure) and complex cloud based routing, a new methodology of ‘Brokering Each Connection’ must be considered.
Unlike BeyondTrust and other PAM (Privileged Access Management) solutions that are limited to Layer 7 management and require complex integration with a multitude of other technologies in order to control other layers,
Blacksands increases security, reduces complexity, and offers global scalability.
The U.S. Treasury hack through BeyondTrust serves as a critical reminder of the continuous need for vigilance, robust security practices, and the potential vulnerabilities introduced by complex supply chains in cybersecurity.
