WARNING: Telstra Resetting Modems To Default Login

UPDATE AUGUST 3, 2022, 1930 HRS

Well, I’m told it’s a Telstra issue, not a cybersecurity issue. Which it is, technically, but Telstra should not being doing this. Their fix was to perform a reset on the modem and if it happens again, a new modem comes my way.

The issue: it’s not the damn modem causing the problem. It’s Telstra.


ADVICE: Telstra users: CHANGE YOUR MODEM LOGIN PASSWORD. Usually connect to your home network and go to 10.0.0.138 (in a browser) or 192.168.1.1, and go from there. Don’t let Telstra’s default stick around, don’t let them reset it to default for god knows what reason.


POSTED LATE AUGUST 2, 2022:

It’s late, I’m tired, but couldn’t get the modem to work – or it would, but I couldn’t log into it without using an ethernet cable.

Turns out they had reset a bunch of settings, and worst by far, the modem configuration password back to the default – accessible from anywhere on the internet.

Telstra F@ST 5355 NBN Modem affected at least – others are simple to crack. Even without logging in, they can be rebooted, shut down, and give out your phone number.

Posting because Telstra have to pick up their damn game.
