HP Releases Firmware Update to Prevent Unauthorized Access

At a moment of weakness it found a lot of debate that emerged about the circumstances in which attacks can be successfully launched and HP had to face much criticism, even from trusted security experts such as Mikko Hypponen. "First of all, how does HP do not have a signature or a certificate showing that the new firmware is the original firmware from HP?" Hypponen said.

Meanwhile, customers who depend on the model of LaserJet printers that have the vulnerability to attack immediately advised to upgrade the firmware on the device to prevent possible adverse incident.

Although HP does not report attacks that use vulnerabilities, but we never know what might have been designed or prepared by the criminals in cyberspace during this period.
