Fake Windows 10 updates are being used to distribute the Magniber ransomware in a massive campaign that started earlier this month. Over the past few days, BleepingComputer has received a surge of requests for help regarding a ransomware infection targeting users worldwide.

While researching the campaign, we discovered a topic in our forums where readers report becoming infected by the Magniber ransomware after installing what is believed to be Windows 10 cumulative or security update.
