WORLDTECHGMO urges customers to shut down PCs after ransomware threat to Onamae Desktop Cloud
Japan's GMO Group has asked customers to disconnect their systems from the internet and shut down their computers after a threat actor who breached its Onamae Desktop Cloud service threatened to launch a ransomware attack.
Warning to customers about the threat
According to a report by BleepingComputer, the GMO Group has urged its customers to cut their systems off from the internet and power down their computers. The instruction follows a threat from an actor who had broken into the company's Onamae Desktop Cloud service, which allows users to run desktop computers remotely.
The threat actor has warned that a ransomware attack, a form of malware that encrypts files and demands payment for their release, would be launched today.
Limits of what is known
The available information comes from a single outlet and rests on the company's warning to customers. The reporting does not say how the intruder gained access to the service, how many customers may be affected, or whether any attack has since taken place.
Open questions
