Brinztech Alert: Unauthorized Admin Access (FortiOS) to American Forensic Lab is on Sale

Dark Web News Analysis

A threat actor on a known cybercrime forum is advertising the sale of unauthorized Administrative and Command Line Interface (CLI) access to a FortiOS-based firewall belonging to an American forensic laboratory.

This claim, if true, represents a critical threat to the integrity of the US justice system.

• The Listing: The seller is not just offering a VPN login; they are selling root-level control (Admin + CLI) over the lab’s security perimeter. CLI access often allows an attacker to bypass the graphical interface logs, create hidden “ghost” admin accounts, and establish deep persistence.
• The Target: A forensic lab handles sensitive digital evidence (e.g., seized hard drives, DNA databases) for law enforcement. A breach here is not just a data theft risk; it is a data tampering risk.
• The Vector: The specific mention of “FortiOS” strongly suggests the attacker is an Initial Access Broker (IAB) weaponizing recent, critical vulnerabilities. In November 2025, multiple Fortinet flaws (such as CVE-2025-58034 and CVE-2025-64446) have been under active exploitation. It is highly probable this lab failed to patch these internet-facing devices.

Key Cybersecurity Insights

This alleged access sale presents a unique and severe threat profile:

• Chain of Custody at Risk: The most critical risk is not theft, but alteration. With admin access, an attacker could theoretically delete logs, modify digital evidence files, or plant exculpatory/incriminating data. If the chain of custody is broken digitally, active criminal cases could be dismissed in court.
• Perimeter Control: Gaining admin/CLI access to the firewall grants full control over the network’s traffic. The attacker can decrypt SSL traffic, re-route evidence uploads to their own servers, or disable logging to cover their tracks.
• Deep System Manipulation: Admin/CLI permissions allow for comprehensive system configuration changes, backdoor installation, and potential complete takeover of the network’s inbound/outbound traffic.
• Reputational & Legal Ramifications: A compromise of this nature could severely impact the integrity of legal proceedings, erode public and client trust, and lead to significant legal and regulatory penalties for the affected forensic lab.

Mitigation Strategies

In response to this claim, the lab and all organizations using Fortinet devices must take immediate action:

• Immediate FortiOS Vulnerability Assessment: Conduct an urgent audit of all Fortinet devices. If the firewall is running an older version of FortiOS, assume it is compromised. Patch immediately against CVE-2025-58034 and related flaws.
• Disable External Admin Access (TOP PRIORITY): Ensure that the administrative interface (HTTP/HTTPS/SSH) is not accessible from the public internet. Restrict management access to a trusted internal VLAN or VPN only.
• Forensic Integrity Check: The lab must immediately verify the integrity of its digital evidence stores. Check checksums/hashes of stored evidence against offline backups to ensure no data manipulation has occurred.
• Enhanced Multi-Factor Authentication (MFA): Enforce mandatory MFA for all administrative access to firewalls. CLI access should be restricted to specific, whitelisted IP addresses and require SSH key-based authentication, not just passwords.
