Ext. Crasher - Chr0meCrash3r (Testing)

[2pro12342]

i found out a way to crash other pages including chrome extension pages using html files/websites (works with html editors). this exploit is useful for the people that cannot access DNS settings on their computer. this is still in testing and this might work.

Tested on:

• Personal chromebook, but school account. (Board: Hana, version: 149 & 150, type: Lenovo no touch screen)
• Chrome OS VM

Requirements:

• HTML coding
• File urls unblocked (if blocked use unblock files method)
• No sh1tty ram (if you have a sh1tty ram, use Sh1ttyLagg3r exploit)
• Phone hotspot (easier) or some way to disconnect your wifi fast (or change wifi disconnecting steps with "unplug your router")

Steps:

1. find your extension blocker's update url and copy it.
2. make an html file that creates a lot of lag to the webpage.
3. in the html code, put in <script>window.open(" [your url here] ");</script> and replace the [your url here] with your extension blocker's update url. (add multiple urls as you want to crash)
4. save your html code (prob save to google drive tab in file manager) and save your account data.
5. sign out and powerwash (Ctrl+Shift+Alt+R) or remove account (down arrow next to your name).
6. connect to your wifi and keep enrolling.
7. as soon as you log in or when that lag happens before log in, immediately disconnect wifi.
8. open html file and when it opens the pages, wait 3-5 seconds and reload page.
9. when it says "Page Unresponsive", connect back to wifi and immediately click "Exit Pages".
   this will break your extension's update url, leading it to crash.

Notes:

• If didn't work for crashing the page, add a lot more lag to your HTML code and save code.
• If the "Page Unresponsive" pop-up disappeared, you have to re-do steps and on step 9, wait longer than 6 seconds and reload page.
• might work on Data URLs
