Australian government urges holidaymakers to kill two-factor auth

Um, not sure you thought this one through


The Australian government is urging its citizens to turn off two-factor authentication while abroad.

The official Twitter account for myGov – a portal for accessing government services online – told Aussies this week: "Going overseas this summer? If you're registered for myGov security codes make sure you turn them off before you go."

The startling tweets come complete with professional cartoon graphics, clearly suggesting that rather than a civil servant going rogue on an idle afternoon, the advice was produced as a matter of policy.

The myGov website allows Australians to tap into a broad range of government services including tax payments, health insurance, child support, and so on. Since this tends to involve sensitive personal information, it's wise to protect one's account with two-factor authentication – such as a one-time code texted to a phone that needs to be given to the website while logging in.

There's a fear that while citizens are overseas, they may not be able to reliably get these text messages (or be charged an extra fee to receive them) if they try to use myGov. So the advice is: turn off this protection when out the country, and turn it back on again when you return.

Except, of course, that rather misses the entire reason for two-factor authentication, and puts convenience above the actual security of your information.

What's more, people are significantly more likely to be using online services in less secure settings when they are abroad, making the decision to remove a vital mechanism all the more likely that their accounts will be compromised.

In other words, this is really terrible advice.

The entire point of two-factor auth is to make it so that if someone manages to snatch a look at your username and password, they can't automatically log into your account.

As such, the Australian government is doing is the exact opposite of what it should be doing, which is educating people about alternative ways to secure their accounts, rather than pushing the crazy message that security is about convenience and that you should simply drop it when it requires a little extra effort. ®

    As a slowdown in PC sales brings down prices for graphics cards, AMD is hoping to win over the market's remaining buyers with a bold, new claim that its latest Radeon cards provide better performance for the dollar than Nvidia's most recent GeForce cards.

    In an image tweeted Monday by AMD's top gaming executive, the chip designer claims its lineup of Radeon RX 6000 cards provide better performance per dollar than competing ones from Nvidia, with all but two of the ten cards listed offering advantages in the double-digit percentages. AMD also claims to provide better performance for the power required by each card in all but two of the cards.

    A futuristic design won't make people want to come back – just ask Apple

    After nearly a decade of planning and five years of construction, Google is cutting the ribbon on its Bay View campus, the first that Google itself designed.

    The Bay View campus in Mountain View – slated to open this week – consists of two office buildings (one of which, Charleston East, is still under construction), 20 acres of open space, a 1,000-person event center and 240 short-term accommodations for Google employees. The search giant said the buildings at Bay View total 1.1 million square feet. For reference, that's less than half the size of Apple's spaceship. 

    The roofs on the two main buildings, which look like pavilions roofed in sails, were designed that way for a purpose: They're a network of 90,000 scale-like solar panels nicknamed "dragonscales" for their layout and shimmer. By scaling the tiles, Google said the design minimises damage from wind, rain and snow, and the sloped pavilion-like roof improves solar capture by adding additional curves in the roof.

  • Pentester pops open Tesla Model 3 using low-cost Bluetooth module
    Anything that uses proximity-based BLE is vulnerable, claim researchers

    Tesla Model 3 and Y owners, beware: the passive entry feature on your vehicle could potentially be hoodwinked by a relay attack, leading to the theft of the flash motor.

    Discovered and demonstrated by researchers at NCC Group, the technique involves relaying the Bluetooth Low Energy (BLE) signals from a smartphone that has been paired with a Tesla back to the vehicle. Far from simply unlocking the door, this hack lets a miscreant start the car and drive away, too.

    Essentially, what happens is this: the paired smartphone should be physically close by the Tesla to unlock it. NCC's technique involves one gadget near the paired phone, and another gadget near the car. The phone-side gadget relays signals from the phone to the car-side gadget, which forwards them to the vehicle to unlock and start it. This shouldn't normally happen because the phone and car are so far apart. The car has a defense mechanism – based on measuring transmission latency to detect that a paired device is too far away – that ideally prevents relayed signals from working, though this can be defeated by simply cutting the latency of the relay process.
