UPDATE: We also recommend reading our additional thoughts about these guidelines to help clarify what types of applications and bugs are eligible for this program.
Q) What classes of bug are in scope? A) It's difficult to provide a definitive list of vulnerabilities that will be rewarded; however, any serious bug which directly affects the confidentiality or integrity of user data may be in scope. We anticipate most rewards will be in bug categories such as:
XSS
XSRF / CSRF
XSSI (cross-site script inclusion)
Bypassing authorization controls (e.g. User A can access User B's private data)
Server side code execution or command injection
Out of concern for the availability of our services to all users, we ask you to refrain from using automated testing tools.
These categories of bugs are definitively excluded:
attacks against Google’s corporate infrastructure
social engineering and physical attacks
denial of service bugs
non-web application vulnerabilities, including vulnerabilities in client applications
SEO blackhat techniques
vulnerabilities in Google-branded websites hosted by third parties
bugs in technologies recently acquired by Google
Q) How far should I go to demonstrate a vulnerability? A) Please, only ever target your own account or a test account. Never attempt to access anyone else's data. Do not engage in any activity that bombards Google services with large numbers of requests or large volumes of data.
Q) I've found a vulnerability — how do I report it? A) Contact details are listed here. Please only use the email address given for actual vulnerabilities in Google products. Non-security bugs and queries about problems with your account should should instead be directed to the Google Help Centers.
Q) What reward might I get? A) The base reward for qualifying bugs is $500. If the rewards panel finds a particular bug to be severe or unusually clever, rewards of up to $3,133.7 may be issued. The panel may also decide a single report actually constitutes multiple bugs requiring reward, or that multiple reports constitute only a single reward.
We understand that some researchers aren’t interested in the money, so we’d also like to give you the option to donate your reward to charity. If you do, we'll match it — subject to our discretion.
Regardless of whether you're rewarded monetarily or not, all vulnerability reporters who interact with us in a respectful, productive manner will be credited on a new vulnerability reporter page. If we file a bug internally, you'll be credited.
Superstar performers will continue to be acknowledged under the "We Thank You" section of this page.
Q) How do I find out if my bug qualified for a reward? A) You will receive a comment to this effect in an emailed response from the Google Security Team.
Q) What if someone else also found the same bug? A) Only the first report of a given issue that we had not yet identified is eligible. In the event of a duplicate submission, only the earliest received report is considered.
Q) Will bugs disclosed without giving Google developers an opportunity to fix them first still qualify? A) We believe handling vulnerabilities responsibly is a two-way street. It's our job to fix serious bugs within a reasonable time frame, and we in turn request advance, private notice of any issues that are uncovered. Vulnerabilities that are disclosed to any party other than Google, except for the purposes of resolving the vulnerability (for example, an issue affecting multiple vendors), will usually not qualify. This includes both full public disclosure and limited private release.
Q) Do I still qualify if I disclose the problem publicly once fixed? A) Yes, absolutely! We encourage open collaboration. We will also make sure to credit you on our new vulnerability reporter page.
Q) Who determines whether a given bug is eligible? A) Several members of the Google Security Team including Chris Evans, Neel Mehta, Adam Mein, Matt Moore, and Michal Zalewski.
Q) Are you going to list my name on a public web page? A) Only if you want us to. If selected as the recipient of a reward, and you accept, we will need your contact details in order to pay you. However, at your discretion, you can choose not to be listed on any credit page.
Q) No doubt you wanted to make some legal points? A) Sure. We encourage broad participation. However, we are unable to issue rewards to individuals who are on sanctions lists, or who are in countries (e.g. Cuba, Iran, North Korea, Sudan and Syria) on sanctions lists. This program is also not open to minors. You are responsible for any tax implications depending on your country of residency and citizenship. There may be additional restrictions on your ability to enter depending upon your local law.
This is not a competition, but rather an experimental and discretionary rewards program. You should understand that we can cancel the program at any time, and the decision as to whether or not to pay a reward has to be entirely at our discretion.
Of course, your testing must not violate any law, or disrupt or compromise any data that is not your own.
Thank you for helping us to make Google's products more secure. We look forward to issuing our first reward in this new program.
