- Usernames and passwords
- Private keys and firewall rules
According to cybersecurity experts, the leak appears to be extensive, with the majority of affected devices located in Mexico (1,603), followed by the United States (679) and Germany (208). Many of these devices are deployed in various sectors, including healthcare and government, making the breach particularly alarming.
The Belsen Group claims that the data was obtained through exploiting vulnerabilities in Fortinet devices. Specifically, the group is believed to have leveraged a zero-day vulnerability tracked as CVE-2022-40684, which was actively exploited before a patch was released. This vulnerability allowed attackers to download configuration files from targeted FortiGate devices and create unauthorized super_admin accounts.
The attack vector likely involved unauthorized administrative logins on management interfaces of the firewalls. Once inside, attackers could alter configurations and extract sensitive credentials using techniques such as DCSync, which simulates a domain controller to extract password hashes for Active Directory accounts.
The implications of this data leak are profound. With access to configuration files and credentials, malicious actors can potentially infiltrate networks, modify firewall settings, and execute further attacks within compromised environments. The availability of plaintext VPN credentials significantly increases the risk of unauthorized remote access to sensitive systems.
Security experts urge organizations that utilize Fortinet devices to take immediate action:
- Assess Exposure: Organizations should check if their devices are among those listed in the leaked data and verify their patch history for CVE-2022-40684.
- Change Credentials: It is critical to change all admin and VPN credentials associated with affected devices immediately.
- Review Firewall Rules: Organizations should conduct thorough reviews of their firewall rules to identify any unauthorized changes or vulnerabilities.
- Implement Enhanced Monitoring: Deploy intrusion detection systems (IDS) and security information and event management (SIEM) solutions to monitor for unusual activity indicative of exploitation attempts.
- Regular Security Audits: Conduct routine security assessments to identify potential vulnerabilities in network infrastructure.
The leak of sensitive data from over 15,000 Fortinet firewalls by the Belsen Group underscores the growing threat posed by cybercriminals targeting critical infrastructure. As organizations scramble to secure their systems in light of this breach, it is essential for them to adopt robust cybersecurity measures and remain vigilant against evolving threats. The incident serves as a stark reminder of the vulnerabilities inherent in interconnected systems and highlights the need for continuous improvement in cybersecurity practices across all sectors.
Over 660,000 Rsync servers exposed to code execution attacks
In a concerning development for cybersecurity, over 660,000 Rsync servers have been exposed to critical vulnerabilities that could allow attackers to execute arbitrary code remotely. This alarming statistic comes from recent findings by security researchers, who identified six significant vulnerabilities in the widely used file synchronization tool, Rsync. These flaws pose serious risks to organizations that rely on Rsync for data transfers and backups.
The vulnerabilities were disclosed following research by teams from Google Cloud and independent security experts. Among the most critical is CVE-2024-12084, a heap-based buffer overflow with a CVSS score of 9.8, indicating its severity. This flaw arises from improper handling of checksum lengths in the Rsync daemon, allowing an attacker with anonymous read access to execute arbitrary code on the server running Rsync. Other notable vulnerabilities include:
- CVE-2024-12085: An information leak vulnerability that allows attackers to extract uninitialized stack data during file checksum comparisons.
- CVE-2024-12086: A server-side flaw enabling arbitrary file enumeration from connected client systems during file synchronization.
- CVE-2024-12087: A path traversal vulnerability that permits malicious servers to write files outside intended directories.
- CVE-2024-12088: A bypass of the –safe-links option, which can lead to unauthorized file writes.
- CVE-2024-12747: A race condition in symbolic link processing that could allow privilege escalation or sensitive information disclosure.
These vulnerabilities primarily affect Rsync versions prior to 3.4.0, which was released on January 14, 2025, to address these critical security issues.
The widespread exposure of Rsync servers is particularly alarming given their extensive use in various sectors, including backup systems, public file distribution, and cloud management operations. A Shodan search revealed that many of these servers are publicly accessible, with a significant concentration in China (over 521,000), followed by the United States and other countries. Attackers exploiting these vulnerabilities could gain control over vulnerable servers simply by having anonymous read access, such as through public mirrors. This access could lead to the extraction of sensitive data like SSH keys or even allow attackers to overwrite critical files on connected clients.
In light of these vulnerabilities, it is crucial for organizations using Rsync to take immediate action:
- Upgrade to Version 3.4.0: All users are strongly advised to upgrade their Rsync installations to version 3.4.0 or later, which addresses all identified vulnerabilities.
- Configuration Review: For those unable to upgrade immediately, it is recommended to configure the Rsync daemon to require authentication instead of allowing anonymous access.
- Network Security Measures: Organizations should consider blocking TCP port 873, commonly used by Rsync, at the perimeter firewall until they can secure their installations.
- Regular Security Audits: Conduct routine assessments of your systems and configurations to identify potential vulnerabilities and ensure compliance with best practices.
The exposure of over 660,000 Rsync servers to critical vulnerabilities highlights a significant risk in cybersecurity infrastructure. As cyber threats continue to evolve, maintaining up-to-date software and implementing robust security measures are essential for protecting sensitive data and preventing unauthorized access. The recent disclosures serve as a reminder of the importance of vigilance in cybersecurity practices and the need for organizations to act swiftly in response to emerging threats.
