Brinztech Alert: Active Directory Access to Uzbekistan’s Largest Telecom, Uztelecom, on Sale

Dark Web News Analysis: Uztelecom Active Directory Access on Sale

A threat actor is selling access to the Active Directory of Uztelecom, Uzbekistan’s largest telecommunications provider. The sale, advertised on a hacker forum, includes the employee emails and passwords for over 1,000 users and represents a critical compromise of national infrastructure. A breach of a national telecom’s central identity management system is one of the most severe security incidents possible. The seller has provided a sample of the data to verify their claim. The assets for sale include:

• Type of Access: “Full access” to Uztelecom’s Active Directory.
• Compromised Credentials: Over 1,000 employee accounts, including their emails and passwords.

Key Cybersecurity Insights

The compromise of Active Directory at a national telecommunications provider is a worst-case scenario that threatens the security of the entire country.

• Active Directory Compromise is a “Keys to the Kingdom” Event: Active Directory (AD) is the central identity and access management system for most large organizations. An attacker with administrative control over AD can control the entire corporate network. They can create new admin accounts, access any data on any server, deploy ransomware or spyware across the entire enterprise, modify logs to erase their tracks, and maintain persistent, undetected access. This is a total network compromise scenario.
• A Direct Threat to National Security and Communications Infrastructure: Uztelecom is not just a company; it is a piece of Uzbekistan’s critical national infrastructure. A compromise of its core network could be leveraged by a hostile state actor to conduct surveillance on a national scale, disrupt essential communication services for citizens and government, or use the trusted network as a launchpad for further attacks against other government and commercial entities in the country.
• Employee Credentials as a Gateway to Widespread Espionage: The 1,000+ stolen employee credentials provide a direct entry point for attackers. Even if the main AD compromise is contained, these credentials will be used for highly targeted spear-phishing attacks against Uztelecom’s partners, large corporate customers, and other government agencies to expand the attacker’s reach and intelligence-gathering capabilities.

Critical Mitigation Strategies

Uztelecom must operate under the assumption that its entire network is controlled by a hostile actor and take immediate, drastic measures.

• For Uztelecom: Assume Total Network Compromise and Initiate Full-Scale Incident Response: This is a code-red situation. The company must assume its entire Active Directory is compromised and untrustworthy. This requires an immediate, top-priority incident response led by external forensic experts to hunt for the adversary, identify the extent of their control, and begin the long and complex process of securely rebuilding the AD environment from scratch.
• For Uztelecom: Mandate an Immediate, Company-Wide Credential Reset and MFA Enforcement: Every single password for every user and service account in the domain must be reset immediately. Enforcing phishing-resistant Multi-Factor Authentication (MFA) on all accounts, especially privileged ones, is non-negotiable to prevent attackers from re-gaining access.
• For Uztelecom Customers and Partners: Be on High Alert for Sophisticated Scams: All corporate customers and partners of Uztelecom should be warned that the provider has suffered a severe breach. They should be on high alert for any unusual communications or sophisticated phishing attempts appearing to come from Uztelecom, as the attackers could potentially control the company’s legitimate email systems.
