Chinese Telecom Firm

The organisation is identified as a Chinese telecommunications company.
Its headquarters is situated in China.
The firm operates within the telecommunications sector, which is considered a critical infrastructure industry in China.
Specific details about its size, subscriber count, or range of services are not provided in the available sources.
The available information does not disclose its ownership structure, parent company, or subsidiary relationships.
Consequently, the profile is limited to the confirmed attributes of being a China‑based telecom provider.

In April 2017 the company experienced a distributed denial‑of‑service attack that lasted 277 hours, setting a record for the longest observed DDoS incident at that time.
The attack was reported by cybersecurity researchers who noted it reflected a broader trend of extortion‑oriented DDoS campaigns demanding payment in cryptocurrency.
Researchers observed that both professional cybercriminal groups and less experienced actors were participating in such prolonged disruptions.
The prolonged disruption caused operational challenges for the firm and posed potential reputational risks.
Victims who might have considered paying a ransom were warned that doing so could attract further attacks from other threat actors.
No definitive motive or attribution for the unprecedented attack duration was established in the reporting.
