Welcome to another edition of Forefront Insights. After feedback from our readers, we decided to start publishing these articles every Monday, instead of Friday, seeing as there are often significant developments in events during the weekend! Today is the 22nd of April, and these are some of the latest in the world of cybersecurity!

Nation-State Breach of The MITRE Corporation

This week, the cybersecurity community was alerted to a sophisticated breach at The MITRE Corporation, carried out by a nation-state actor. MITRE is integral to U.S. national security, managing several federally funded research and development centers. The breach involved the exploitation of two critical vulnerabilities: CVE-2023-46805, with a CVSS score of 8.2, and CVE-2024-21887, with a CVSS score of 9.1. These vulnerabilities allowed attackers to bypass authentication mechanisms and execute arbitrary commands on compromised systems.

The attackers commenced their campaign with spear-phishing emails, which led to the installation of backdoor payloads for initial access. Subsequently, they exploited the above-mentioned CVEs to gain deeper access and control over MITRE’s systems. Following initial compromise, the attackers moved laterally within the network, targeting and breaching its VMware infrastructure using a compromised administrator account. This lateral movement enabled the deployment of additional backdoors and web shells, which facilitated persistence within the network and credential harvesting.

It's important to note, however, that MITRE has indicated that their core enterprise network, known as NERVE—an unclassified collaborative network providing storage, computing, and networking resources—was not impacted by this breach. This suggests that while the attackers were able to infiltrate certain aspects of MITRE’s systems, the core operational infrastructure remains secure, and there is no evidence of partner systems being affected.

For our clients, this underscores the importance of securing organizational perimeters against similar sophisticated threats. Strengthening endpoint security, enhancing user authentication processes, and increasing network monitoring are essential steps to safeguard sensitive data from such high-level intrusions.

Networkless Identity Attacks

With the escalation of identity-based attacks, we are witnessing a significant shift in the cybersecurity landscape. CrowdStrike's latest global threat report indicates that 75% of access-related attacks were malware-free, relying instead on more discreet techniques such as credential theft and manipulation of standard authentication processes. This reflects a growing trend towards "cloud-conscious" attacks, which have seen a dramatic increase of 110%. These attacks are deliberate attempts to target cloud services, aiming to compromise specific functionalities rather than opportunistically exploiting vulnerabilities.

Furthermore, Microsoft reports approximately 4,000 password attacks per second targeting cloud identities. Google has also indicated that attacks designed to steal session cookies—to bypass multi-factor authentication (MFA)—are occurring with alarming frequency, nearly on par with password-based attacks.

High-profile attacks by groups like APT29 (also known as Cozy Bear or The Dukes) and Scattered Spider (also known as 0ktapus), targeting Identity Provider (IdP) services, Software as a Service (SaaS) applications, and single sign-on/OAuth mechanisms, demonstrate the strategic focus of modern threat actors. These breaches against major platforms like Microsoft and Okta highlight the critical need for robust identity protection strategies.

In response to these developments, it is essential for organizations to enhance their identity protection measures. This can include strengthening user authentication processes, implementing zero-trust frameworks, and increasing awareness and training for employees to recognize and mitigate the risks associated with identity-based attacks. We work closely with our partners to secure their SaaS apps and wider infrastructure using advanced Zero Trust solutions from Cloudflare and Duo.

GitHub Comments Abused to Spread Malware

A novel malware distribution method has been reported involving the abuse of GitHub comments. Attackers are embedding malicious URLs within comments on popular repositories, which then redirect to malware-laden sites when clicked by unsuspecting users. This technique highlights a new vector of attack—abusing the trust and utility of platforms like GitHub to spread harmful software.

Organizations must educate their developers about the risks of interacting with unknown links and ensure that proper security measures are in place, including the use of web filtering and anti-malware solutions to prevent such threats from compromising systems.
