Last week, Motherboard revealed that hackers had broken into the servers that belong to ASUS, the Taiwanese computer giant.

Once inside, the hackers pushed out a malicious update signed with a legitimate digital certificate to thousands of ASUS customers. Kaspersky Lab, which discovered the attack, estimates that around 500,000 people received this update. The hackers, however, were only targeting 600 of them.
