A flaw in cable modems called “Cable Haunt’ puts hundreds of millions at risk from hackers.
Cable Haunt
The flaw is found in a Broadcom system on a chip used in many modems, in the software that runs the spectrum analyzer. A hacker needs to be on your local network in order to exploit it, but if successful they could take control, send you to malicious websites, perform a man-in-the-middle attack, or even change the modem’s firmware.

Modems confirmed by ISPs or the researchers
There isn’t much you can do though. It requires a patch from your ISP, but so far only four companies in Scandinavia have provided patches.

Modems confirmed by the community
You can see in the images above which modems are affected. To see if a patch is available you’ll have to contact your ISP.
