Since the previous hacks stopped working, I started looking into new methods of getting cheap chicken. I noticed that the KFC app seems to only perform client side validation of whether your cart is valid (very bad cybersecurity), so I found a new method of getting the hack which works on the KFC website ordering. The method involves performing a replay attack on the add to cart request sent to the server. Unfortunately this method only works on PC, so it is not very convenient to use, but I believe that it might still be possible on the app due to lack of server side cart validation.

Steps:

  1. Open KFC website (https://www.kfc.com.au/menu/shared-meals/burger-feast)
  2. Add burger feast to cart (Other feasts might also work)
  3. Open browser developer tools (Ctrl + Shift + I), then go to the network tab
  4. Add the add on you want to cart
  5. In the developer tools, identify the network request that corresponds to adding the add on to cart (POST request, URL ends with /line-items)
  6. Go to cart and remove the feast, it will remove the add on as well. (Hint: do this in another tab so the developer tools does not get cluttered with extra network requests).
  7. Go back to browser developer tools and replay the request identified in step 5. (right click, then Resend in Firefox or Replay XHR in Chrome)
  8. Refresh the cart page and the add on should be in there.

See also alternative hack by ThristyCow, which does not use developer tools and can be performed on mobile:

  1. Open 2 tabs of the KFC site.
  2. On tab #1, add the Burger Feast to the cart and do not press anything when Add-ons menu appears.
  3. Switch to tab #2 and navigate to cart and remove the feast
  4. Switch to tab #1 and click Add to Order on the add-on you want.

        "unauthorised modification of data", it is considered a criminal activity, combined with obtaining advantage by deception. You are intentionally bypassing their security even though the security is obviously written by a first year computer grad as anyone else in the industry knows the very first computer lesson is never rely on client side validation. No They are unlikely to come after you for this, but make no mistake it is most definitely a crime.

    I've gone so far as to stop the KFC app from updating on my phone. So the last hack still works for me. Yes, I now have to manually update each one of my apps, but the love of the chicken keeps me going.

          100% agree looks like KFC added extra spices to suit local palate. The one in Indonesia has more spices flavour which I like

  • vorsprung on 01/07/2024 - 17:04

    I wouldn't do this, especially after giving detailed instructions on a public forum. When their app has a bug or glitch that you exploit, you could play dumb. When you're intentionally bypassing client side validation and replaying HTTP messages it's a bit more deliberate.

    I agree they shouldn't rely on client-side validation but that's beside the point.

    I'll probably get downvoted like the other nay-sayer…

    Nice got it to work.

    A tip for those on MS Edge

    Go to network tab first and 'stop' recording network log so it doesn't spam the log with data you do not want. Start recording just before you add the add-on then stop it afterwards.

    Coles has lowered the Steggles Chicken Wings for $9.9,they are more juicy than KFC pieces and thats the best case if the kids not overcooked your chicken,only if you dont have microwave or air fryer,this "hack"might be ok,by the way KFC chicken are made and marinated by Baiada(Steggles) anyway

  • ThirstyCow on 01/07/2024 - 18:18

    There is a alternative method to do this also in web browsers which doesnt involve the developer tools and it works on phone as well.
    1. Open 2 tabs of the KFC site.
    2. On tab #1, add the Burger Feast to the cart and do not press anything when Add-ons menu appears.
    3. Switch to tab #2 and navigate to cart and remove the feast
    4. Switch to tab #1 and click Add to Order on the add-on you want.

    You should then have the addon only in the cart and can checkout as usual.

    Nice to see people innovating for a bargain.

      • AwesomeAndrew on 02/07/2024 - 12:21
        +1

        I guess this method exploits a race condition in the case of 2 tabs, so it is slightly different, but if they patch it properly by doing server side cart validation then the hacking will be over for good.

        • gromit on 03/07/2024 - 08:20
          +1

          kinda but not really, race condition is something else. This basically is just utilising shared data (cookies) on the client side and the scripts have poor validation through cross session data access. Race conditions are when 2 threads try to change the data at the same time.

      If you happen to have one of the online feedback voucher code for a 600ml soft drink (now it's an email with a code), choose pickup at drive thru. When you're at the speakerphone, tell them your order number, also tell them you want to redeem a free drink from the feedback page. Show them your phone screen with the email on it (they don't really read it anyway) and you can reuse the same voucher again again and again. Been working since they have this online voucher code thing earlier this year. YMMV.
