Brinztech Alert: Unauthorized Network Access Sale Detected for an Italian Company

A threat actor is selling what is claimed to be domain administrator access to an Italian company on a prominent hacker forum. Brinztech’s analysis of the listing reveals that the unauthorized access is provided via RDWeb (Remote Desktop Web Access) for a company with an estimated annual revenue of €15 million. The asking price for these high-level credentials is set at $1500, positioning it as a turnkey entry point for a devastating cyberattack.

The sale of domain administrator credentials is one of the most severe security incidents a company can face. This level of access is equivalent to having the “keys to the kingdom,” granting an attacker complete control over the organization’s entire Windows network environment. There is no need for further privilege escalation; the buyer can immediately begin to exfiltrate data, deploy ransomware, create backdoor accounts, and erase their tracks. This incident highlights the dangerous role of initial access brokers (IABs) in the cybercrime ecosystem, who specialize in breaching networks and selling access to the highest bidder.

Key Cybersecurity Insights

This network access sale represents a critical and immediate threat:

• ‘Keys to the Kingdom’ for Sale: Domain admin privileges allow an attacker to control the entire Active Directory domain. They can create, modify, and delete user accounts; access any file on any connected server or workstation; deploy software (including malware) across the entire network; and disable security tools, making a successful defense nearly impossible.
• Direct Pathway to a Ransomware Attack: Ransomware groups are the primary customers for this type of access. By purchasing domain admin credentials, they can bypass the initial intrusion phase and move directly to deploying their ransomware payload across every system in the network, ensuring maximum disruption and increasing the likelihood of a large payout.
• RDWeb as a High-Risk Attack Vector: Remote Desktop Web Access is a common tool for enabling remote work, but it is also a popular target for attackers. If not properly secured—specifically with Multi-Factor Authentication (MFA)—it can serve as a direct gateway into the heart of a corporate network, as demonstrated by this incident.

Mitigation Strategies

Organizations must take immediate and decisive action to defend against such threats:

• Assume Compromise and Hunt for Threats: The targeted company must operate under the assumption that its network is already compromised. This means immediately activating an incident response plan and deploying forensic teams to hunt for any signs of malicious activity, such as unusual logins, new account creations, or suspicious scripts.
• Enforce MFA on All External Access Points: This is the single most effective defense against credential compromise. All remote access solutions, including RDWeb, VPNs, and other portals, must be protected with mandatory Multi-Factor Authentication. No exceptions should be made for any user, especially administrators.
• Immediately Rotate All Privileged Credentials: All passwords for domain administrators, service accounts, and other high-privilege users must be immediately reset. It is crucial to ensure that any potential footholds the attacker has established using the compromised credentials are severed.
