Brinztech Alert: Unauthorized Network Access Sale Detected for a Portuguese IT Company

Dark Web News Analysis

A threat actor on a known cybercrime forum is advertising the sale of unauthorized network access to a Portuguese IT company. This is a classic Initial Access Broker (IAB) listing, representing an immediate and severe threat.

The seller is offering access for a surprisingly low price of $1,000. The listing details are specific and alarming:

• Target: A Portuguese IT Company.
• Infrastructure: VMware Cloud and Veeam Cloud environments.
• Scope: 41 hosts, including 39 servers.
• Capability: The seller explicitly mentions the ability to extract data from Veeam backups.

Brinztech Analysis: This listing fits the profile of a Supply Chain Attack vector. By compromising an IT service provider, the attacker potentially gains access to the data and systems of the provider’s numerous corporate clients. The specific mention of “extracting data from Veeam” is a critical technical indicator. It suggests the attacker may be exploiting recent vulnerabilities such as CVE-2024-40711 (a critical RCE in Veeam Backup & Replication patched in Sept 2024) or using known credential dumping techniques to harvest passwords stored within the backup server. The low price ($1,000) suggests the seller wants a quick turnover to a ransomware affiliate who will likely deploy encryption immediately.

Key Cybersecurity Insights

This alleged access sale presents a critical and immediate threat:

• High-Impact Supply Chain Risk: Compromise of an IT company with numerous corporate contracts poses a significant supply chain threat. An attacker could leverage this access to “island hop” into the networks of the IT company’s clients, magnifying the impact.
• Direct Data Exfiltration Threat: The ability to access and download files from Veeam backups defeats the primary purpose of a backup strategy. It allows attackers to steal sensitive data without tripping alerts on the live production servers.
• Critical Infrastructure Compromise: Access to both VMware virtualization (the compute layer) and Veeam (the recovery layer) grants an attacker total control. They can delete backups before deploying ransomware to the virtual machines, ensuring maximum leverage for extortion.
• Low Barrier to Entry: The $1,000 price point is dangerously low for administrative access to 39 servers. This makes the target accessible to a wide range of threat actors, from low-level data thieves to sophisticated ransomware gangs.

Mitigation Strategies

In response to this claim, the company and its clients must take immediate action:

• Immediate Validation & Incident Response: Prioritize validating the authenticity of the alleged breach. Check logs for unauthorized access to Veeam consoles or unusual data transfers from backup repositories.
• Secure Backup Infrastructure: Ensure Veeam backups are immutable (cannot be deleted or modified) and air-gapped (logically isolated from the primary network). If the attacker has admin access to the Veeam server, standard backups are likely already compromised.
• Enhance Access Management & MFA: Implement Multi-Factor Authentication (MFA) for all administrative interfaces, especially for VMware vCenter and Veeam consoles. Review privileged accounts for any new, unauthorized users created by the IAB.
• Patch Veeam & VMware: Verify that all Veeam Backup & Replication servers are patched against CVE-2024-40711 and other recent critical flaws. Unpatched backup servers are a primary target for IABs in late 2024/2025.
