Comcast is leaking the names and passwords of customers’ wireless routers

Comcast has simply been caught in a significant safety snafu: revealing the passwords of its prospects’ Xfinity-provided wi-fi routers in plaintext on the net. Anybody with a subscriber’s account quantity and avenue tackle quantity will likely be served up the wi-fi identify and password through the corporate’s Xfinity web activation service.

Safety researchers Karan Saini and Ryan Stevenson reported the issue to ZDnet.

The positioning is supposed to assist individuals establishing their web for the primary time: ideally, you place in your knowledge, and Comcast sends again the router credentials whereas activating the service.

The issue is threefold:

  1. You possibly can “activate” an account that’s already lively
  2. The info required to take action is minimal and it isn’t verified through textual content or electronic mail
  3. The wi-fi identify and password are despatched on the net in plaintext

Because of this anybody along with your account quantity and avenue tackle quantity (e.g. the 1425 in “1425 Alder Ave,” no avenue identify, metropolis, or house quantity wanted), each of which might be discovered in your paper invoice or in an electronic mail, will immediately be given your router’s SSID and password, permitting them to log in and use it nevertheless they like or monitor its visitors. They might additionally rename the router’s community or change its password, locking out subscribers.

This solely impacts individuals who use a router offered by Xfinity/Comcast, which comes with its personal identify and password inbuilt. Although it additionally returns customized SSIDs and passwords, since they’re synced along with your account and might be modified through app and different strategies.

What are you able to do? Whereas this downside is at giant, it’s no good altering your password — Comcast will simply present any malicious actor the brand new one. So till additional discover all of Comcast’s Xfinity prospects with routers offered by the corporate are in danger.

One factor you are able to do for now could be deal with your private home community as if it’s a public one — if you happen to should use it, make certain encryption is enabled if you happen to conduct any non-public enterprise like shopping for issues on-line. What is going to probably occur is Comcast will difficulty a discover and ask customers to vary their router passwords at giant.

One other is to purchase your personal router — it is a good concept anyway, as it would pay for itself in a number of months and you are able to do extra stuff with it. Which to purchase and easy methods to set up it, nevertheless, are past the scope of this text. However if you happen to’re actually nervous, you could possibly conceivably repair this safety difficulty right now by bringing your personal {hardware} to the cut price.

I’ve contacted the corporate for remark and can replace after I hear again.
