A1 Telekom, the largest internet service provider in Austria, has admitted to a security breach this week, following a whistleblower's exposé.

The company admitted to suffering a malware infection in November 2019. A1 said its security team detected the malware a month later, but that removing the infection was more problematic than it initially anticipated.
A1, which didn't disclose the nature of the malware, didn't say if the intruders were financially-focused cybercrime gang or a nation-state hacking group.

The attacker supposedly took manual control of the malware and attempted to expand this initial foothold on a few systems to the company's entire network.
In interviews with Austrian press [1, 2, 3], A1 said that the complexity of its internal network helped prevent the attacker from making their way to other systems "because the thousands of databases and their relationships are by no means easy to understand for outsiders."

A1 told German news site Heise that despite a pretty serious compromise that lasted more than six months, the attacker did not get their hands on any sensitive customer data.

Christian Haschek, the Austrian blogger and security researcher who first broke the story, said the whistleblower claimed the hack was carried out by Gallium, a codename used by Microsoft to describe a Chinese nation-state hacking group specialized on hacking telecom providers worldwide.
