Details are light at the moment, but a bit of news out of Google’s Playtime developer event this morning: the company is launching a Google Play bug bounty program that’ll encourage researchers to poke around and look for vulnerabilities in some of Android’s most popular apps (both those built by Google and those built by third-party devs.)

Called the “Google Play Security Reward” program, the new program aims to get researchers to work directly with Android app developers to find vulnerabilities.

If you help a developer squash a bug, Google will pay you $1,000 (on top of whatever bounty the third-party dev themselves might pay).

Google is tapping HackerOne to handle much of the back end for this program, from submitting reports to inviting white-hat hackers into new parts of the program as they roll out.

The newly discovered KRACK exploit affects the WPA2 security protocol, a standard for Wi-Fi security used on almost every Wi-Fi router.

In theory it allows a hacker within range of a Wi-Fi network to read passwords, credit card numbers and photos sent over the internet.  

Other sensitive information that can be obtained thanks to this exploit is chat app messages and e-mails.

Open the console, run cmd.exe (Run as Administrator, {Right click on Window Logo, and choose CMD Run as Administrator}), then, execute the following 3 commands in turns. (after each command there should be status OK).

cmd run as admin


  1. netsh advfirewall firewall add rule dir=in action=block protocol=TCP localport=135 name="Block_TCP-135"
  2. netsh advfirewall firewall add rule dir=in action=block protocol=TCP localport=139 name="Block_TCP-139"
  3. netsh advfirewall firewall add rule dir=in action=block protocol=TCP localport=445 name="Block_TCP-445"
