BleepingComputer reports that Onamae Desktop Cloud, a provider of VPS services in Japan, was hacked. The attackers compromised the company's infrastructure and installed malware on customer servers. The report puts the number of affected servers at up to 26,739, or roughly 27,000.
The source does not specify what kind of malware was used, how the attackers gained access, or whether customer data was stolen. It also does not say how the company discovered the breach or what steps it has taken. Those details may come to light as the incident is investigated.
The case highlights the scale of damage possible when a managed hosting provider's own infrastructure is compromised. A single intrusion can cascade across many customer environments, and the 26,739 figure is an upper-bound estimate based on the current report.
