It operates as a telecommunications firm providing services to customers in the Slovak market. Service offerings include internet access, as evidenced by disruptions reported in a 2022 cyberattack. Television service delivery is also part of its portfolio, noted during the same 2022 incident. The firm’s association with the T‑Mobile brand indicates involvement in mobile communications.

On 2025-04-18, the telecommunications firm detected a cybersecurity breach in which hackers infiltrated its internal systems and installed malware. Upon detection, the organization promptly removed the malicious software from its network. Affected equipment was isolated to prevent further spread of the infection. A full-scale investigation was launched to determine the origin and extent of the breach. The investigation noted a possible leak of USIM card data, although no confirmed misuse of such information has been reported. Authorities including the Korea Internet & Security Agency and the Ministry of Science and ICT are examining the incident’s scope and underlying cause. In response, the company has reinforced its defenses against illegal USIM swap attempts. It is providing free protection services to customers concerned about potential data exposure. On 2022-06-26, a major Slovak telecommunications provider was hit by a ransomware attack carried out by a threat actor group. The ransomware deployment caused operational disruptions and resulted in unauthorized access to internal data. As a precaution, the provider took its critical infrastructure offline to contain the breach. During mitigation, customer-facing services such as internet and television experienced intermittent outages. The attackers asserted that they had exfiltrated sensitive information from the compromised systems. The full extent of any data loss remains under investigation as of the latest reports. Recovery efforts involved restoring affected systems from secure backups. Following restoration, the organization implemented enhanced security protocols to reduce future risk.
