If you own your cable modem, your first step should be to find out if the modem has a Broadcom chipset.

If so, then ask when a firmware update might be coming. If you rent your cable modem, or a combined cable modem/router, from your ISP, then contact your ISP and ask whether your model is vulnerable to the Cable Haunt flaw. The Lyrebirds researchers say models known to be vulnerable include the Arris Surfboard CM8200A, Arris Surfboard SB6183 (misspelled by Lyrebirds as the nonexistent SB6813), Arris Surfboard SB8200, COMPAL 7284E, COMPAL 7486E, Humax HGB10R-02, Netgear C6250EMR, Netgear CG3700EMR, Netgear CM1000, Sagemcom 3686, Sagemcom 3890, Technicolor TC4400, Technicolor TC7230 and Technicolor TC7300, although some firmware versions of those models may not be at risk. The Lyrebirds team thinks nearly 200 million cable modems may be vulnerable to Cable Haunt in Europe alone. the spectrum analyzer's websocket server is not compatible with the websocket version used in Firefox." However, it adds that "other techniques to exploit specific modems" do work in Firefox. The Cable Haunt website FAQ notes that "in general. Using Mozilla Firefox exclusively for the time being might also help.

It's not clear why Lyrebirds implied that those ISPs had patched their customers' modems only after receiving notice from the researchers, if Broadcom provided a patch several months ago. Four internet service providers in Scandinavia have remotely patched their customers' cable modems, but ISPs in the rest of the world don't seem to have caught on yet.
Unfortunately, there isn't much you can do about the Cable Haunt flaw yet. What you can, and can't, do about Cable Haunt Successful attackers could seize control of the modem and send users of the compromised network to malicious websites, conduct man-in-the-middle attacks on online transactions, or change the modem's firmware, said researchers at Lyrebirds, the Danish security firm that found Cable Haunt and put up a website detailing the flaw.
