Recent research reveals that some series of HP printers have firmware issues that can cause major information leaks, especially when we're thinking about printers in large networks. While especially-devised documents can be infected with malicious code, printing them can give a hacker complete access over the respective printer, and allow them to perform network scans, or copy all printed documents and have them sent to a specific IP.
Installing the new firmware version for the printers in the list below is mandatory, if you hold your security dear.
Please note, though, that the updated firmware does not solve the entire problem; there still are some issues being addressed as you read, and new firmware will most likely surface again soon.
We'll keep you posted as we learn about anything new happening in this field. Until then,
please check the firmware download link for the affected printers and see if you find yours in the list below:
