Fortinet Cybersecurity Breach Exposes Sensitive Customer Data

 

Fortinet experienced a significant cybersecurity breach involving a third-party cloud drive, where 440 GB of data was leaked by a hacker named “Fortibitch” after the company refused to pay the ransom. The breach affected about 0.3% of Fortinet’s customers, roughly 1,500 corporate users, and included sensitive information such as financial documents, HR data, customer details, and more. Experts highlight that the breach underscores the critical need for implementing rigorous cybersecurity measures like multi-factor authentication (MFA) and robust identity access management (IAM) systems. 

Multi-factor authentication is particularly emphasized as a vital layer of defense against unauthorized access, significantly reducing the risk of data exposure when combined with strong identity access management. Organizations need to ensure that they enforce MFA and other identity management protocols consistently, especially for accessing essential systems like SharePoint and cloud storage services. Jim Routh, Chief Trust Officer at Saviynt, pointed out the growing concern over cloud security, given its increased adoption in software development and data storage. He stressed that without proper safeguards, such as MFA and secure access controls, sensitive data is at risk of exposure. 

Cybersecurity analyst Koushik Pal from CloudSEK echoed this sentiment, advocating for stricter IAM policies and urging organizations to regularly monitor repositories for potential misconfigurations, exposed credentials, or sensitive data leaks. This kind of vigilance is necessary for all teams to adhere to security best practices and minimize vulnerabilities. Relying on third-party vendors for data storage, as Fortinet did, is not inherently dangerous but introduces additional risks if strict security protocols are not enforced. The breach serves as a reminder that even established cybersecurity companies can fall victim to attacks, highlighting the need for ongoing vigilance. 

According to Routh, it’s crucial for system administrators to manage accounts meticulously, ensuring that identity access management protocols are properly configured and that privileged access is monitored effectively. The breach exemplifies how cybercriminals exploit security weaknesses to gain unauthorized access to sensitive data. As cloud technologies continue to be integrated into businesses, the responsibility to protect data becomes increasingly important. Cybersecurity experts emphasize that organizations must invest in proper training, regularly update security measures, and remain vigilant to adapt to evolving cyber threats. 

Ensuring that MFA, identity management systems, and monitoring practices are in place can go a long way in protecting against similar breaches in the future. This Fortinet incident serves as a wake-up call, showing that no organization is entirely immune to cyber threats, regardless of its expertise in cybersecurity.

Ransomware Groups Exploit VMware ESXi Bug for Widespread Attacks

 

Several ransomware groups have been exploiting a vulnerability in VMware ESXi hypervisors that allows them to bypass authentication and rapidly deploy malware across virtual environments. Identified as CVE-2024-37085, this bug has been assigned a “medium” severity rating of 6.8 out of 10 on the CVSS scale. The rating reflects the need for attackers to have existing permissions in a target’s Active Directory (AD) to exploit it. 

The vulnerability, identified as CVE-2024-37085, has been assigned a “medium” severity score of 6.8 out of 10 on the CVSS scale. This score reflects the fact that attackers need existing permissions in a target’s Active Directory (AD) to exploit it. However, if attackers have AD access, they can inflict substantial damage. The CVE-2024-37085 bug allows them to instantly elevate their ESXi privileges to the highest level, enabling the deployment of ransomware, data theft, lateral movement within the network, and more. 

Notably, groups such as Storm-0506 (also known as Black Basta), Storm-1175, Manatee Tempest (part of Evil Corp), and Octo Tempest (also known as Scattered Spider) have utilized this vulnerability to distribute ransomware like Black Basta and Akira. Broadcom has released a fix for the vulnerability, which is available on its website. The vulnerability arises in scenarios where organizations configure their ESXi hypervisors to use AD for user management. By default, ESXi hypervisors grant full administrative access to any member of an AD domain group named “ESX Admins.” This oversight means that an attacker with sufficient AD privileges can create an “ESX Admins” group in the targeted domain and add a user to it, thereby gaining full administrative access to the ESXi hypervisors. Alternatively, they could rename an existing group to “ESX Admins” and use one of its existing users or add a new one. 

This vulnerability is problematic because ESXi hypervisors do not validate the existence of the “ESX Admins” group when joining a domain. The membership in this group is determined by name rather than by security identifier (SID), making the exploit straightforward. An attacker only needs to create or rename a group to “ESX Admins” to exploit the vulnerability. Ransomware attacks targeting ESXi hypervisors and virtual machines (VMs) have become increasingly common, particularly since 2020, as enterprises have accelerated their digital transformation efforts and adopted modern hybrid cloud and virtualized on-premise environments. 

Virtualized environments offer hackers significant advantages, as hypervisors typically run many VMs simultaneously, making them ideal targets for widespread ransomware deployment. These VMs often host critical services and business data, making successful attacks highly disruptive. The limited visibility and protection for hypervisors from traditional security products exacerbate this issue. Hypervisors’ isolation and complexity, along with the specialized knowledge required to protect them, make it difficult for conventional security tools to monitor and safeguard the entire environment. 

Additionally, API integration limits further complicate protection efforts. To mitigate these risks, Microsoft emphasizes the importance of keeping systems up to date with patches and practicing broader cyber hygiene around critical and vulnerable assets. Ensuring that systems are patched and that cyber hygiene practices are in place can help defend against such attacks. As ransomware actors increasingly target these systems, organizations must remain vigilant and proactive in their cybersecurity measures.
