Hackers log in by fax

What many companies do not know is that they have a fax, because in last generation printers we find an integrated one. Hackers simply need to obtain the company's fax number, which in many cases is on their own website or in the store. They then send a file with an image, which the device will decode and load into its memory.

And in this way they manage to introduce a malicious program into the network to which this fax / printer is connected. Thus they can end up taking control, causing the connection to be interrupted or having access to confidential data.

The vulnerability has been discovered in one model of HP fax printer, but it is expected that more models will suffer from the same problem. Therefore, it is recommended to be careful and separate the fax from other devices on the network, to make things difficult for hackers. Having the latest security patches is also important.
