We have long enjoyed a close relationship with the security research community. To honor all the cutting-edge external contributions that help us keep our users safe, we maintain a Vulnerability Reward Program for Google- owned web properties, running continuously since November 2010.
In principle, any Google-owned web service that handles reasonably sensitive user data is intended to be in scope. This includes virtually all the content in the following domains:
Bugs in Google Cloud Platform, Google-developed apps and extensions (published in Google Play, in iTunes, or in the Chrome Web Store), as well as some of our hardware devices (Home, OnHub and Nest) will also qualify. See our Android Rewards and Chrome Rewards for other services and devices that are also in scope.
On the flip side, the program has two important exclusions to keep in mind:
Any design or implementation issue that substantially affects the confidentiality or integrity of user data is likely to be in scope for the program. Common examples include:
New! In addition, significant abuse-related methodologies are also in scope for this program, if the reported attack scenario displays a design or implementation issue in a Google product that could lead to significant harm.
An example of an abuse-related methodology would be a technique by which an attacker is able to manipulate the rating score of a listing on Google Maps by submitting a sufficiently large volume of fake reviews that go undetected by our abuse systems. However, reporting a specific business with likely fake ratings would not qualify.
Note that the scope of the program is limited to technical vulnerabilities in Google-owned browser extensions, mobile, and web applications; please do not try to sneak into Google offices, attempt phishing attacks against our employees, and so on.
Out of concern for the availability of our services to all users, please do not attempt to carry out DoS attacks, leverage black hat SEO techniques, spam people, or do other similarly questionable things. We also discourage the use of any vulnerability testing tools that automatically generate very significant volumes of traffic.
New! Visit our Bug Hunter University page dedicated to common non-qualifying findings and vulnerabilities.
Depending on their impact, some of the reported issues may not qualify. Although we review them on a case-by-case basis, here are some of the common low-risk issues that typically do not earn a monetary reward:
Monetary rewards aside, vulnerability reporters who work with us to resolve security bugs in our products will be credited on the Hall of Fame. If we file an internal security bug, we will acknowledge your contribution on that page.
New! Vulnerabilities in the Google Cloud Platform are also eligible for an additional $100,000 prize. Read the official rules for the GCP VRP Prize here and nominate your vulnerability write-ups for the prize here.
Rewards for qualifying bugs range from $100 to $31,337. The following table outlines the usual rewards chosen for the most common classes of bugs. To read more about our approach to vulnerability rewards you can read our Bug Hunter University article here

Mobile / Hardware: "Information leak, privilege escalation" | $500 - $7,500 | $500 - $5,000 | $500 - $3,133.7 | $100
" For example, for web properties this includes some vulnerabilities in Google Accounts (https://accounts.google.com)."
" This category includes products such as Google Search (https://www.google.com and https://encrypted.google.com), Google Wallet (https://wallet.google.com), Google Mail (https://mail.google.com), Google Inbox (https://inbox.google.com), Google Code Hosting (https://code.google.com), Chromium Bug Tracker (https://bugs.chromium.org), Chrome Web Store (https://chrome.google.com), Google App Engine (https://appengine.google.com), Google Admin (https://admin.google.com), Google Developers Console (https://console.developers.google.com), and Google Play (https://play.google.com)."
" Note that acquisitions qualify for a reward only after the initial six- month blackout period has elapsed."
New! Rewards for abuse-related methodologies are based on a different scale and range from USD $100 to $5,000. The reward amount for these abuse- related bugs depends on the potential probability and impact of the submitted technique.
| Impact 
| High | Medium | Low
Probability  | High | Up to $5,000 | $1,337 to $3,133.7 | $500
Medium | $1,337 to $3,133.7 | $500 | $100
Low | $500 | $100 | HoF Credit
" The impact assessment is based on the attack’s potential for causing privacy violations, financial loss, and other user harm, as well as the user- base reached."
" The probability assessment takes into account the technical skill set needed to conduct the attack, the potential motivators of such an attack, and the likelihood of the vulnerability being discovered by an attacker."
The final amount is always chosen at the discretion of the reward panel. In particular, we may decide to pay higher rewards for unusually clever or severe vulnerabilities; decide to pay lower rewards for vulnerabilities that require unusual user interaction; decide that a single report actually constitutes multiple bugs; or that multiple reports are so closely related that they only warrant a single reward.
We understand that some of you are not interested in money. We offer the option to donate your reward to an established charity. If you do so, we will double your donation - subject to our discretion. Any rewards that are unclaimed after 12 months will be donated to a charity of our choosing.
When investigating a vulnerability, please, only ever target your own accounts. Never attempt to access anyone else's data and do not engage in any activity that would be disruptive or damaging to your fellow users or to Google.
New! Visit our Bug Hunter University articles to learn more about sending good vulnerability reports.
If you have found a vulnerability, please contact us at goo.gl/vulnz. Please be succinct : the contact form is attended by security engineers and a short proof-of-concept link is more valuable than a video explaining the consequences of an XSS bug. If necessary, you can use this PGP key.
Note that we are only able to answer to technical vulnerability reports. Non- security bugs and queries about problems with your account should be instead directed to Google Help Centers.
Q: What if I found a vulnerability, but I don't know how to exploit it?
A: We expect that vulnerability reports sent to us have a valid attack scenario to qualify for a reward, and we consider it as a critical step when doing vulnerability research. Reward amounts are decided based on the maximum impact of the vulnerability, and the panel is willing to reconsider a reward amount, based on new information (such as a chain of bugs, or a revised attack scenario).
Q: How do I demonstrate the severity of the bug if I’m not supposed to snoop around?
A: Please submit your report as soon as you have discovered a potential security issue. The panel will consider the maximum impact and will choose the reward accordingly. We routinely pay higher rewards for otherwise well-written and useful submissions where the reporter didn't notice or couldn't fully analyze the impact of a particular flaw.
Q: I found an outdated software (e.g. Apache or Wordpress). Does this qualify for a reward?
A: Please perform due diligence: confirm that the discovered software had any noteworthy vulnerabilities, and explain why you suspect that these features may be exposed and may pose a risk in our specific use. Reports that do not include this information will typically not qualify.
Q: Who determines whether my report is eligible for a reward?
A: The reward panel consists of the members of the Google Security Team. The current permanent members are Daniel Stelter-Gliese, Eduardo Vela Nava, Gábor Molnár, Krzysztof Kotowicz, Martin Straka, and Michael Jezierny. In addition there is a rotating member from the rest of our team.
Q: What happens if I disclose the bug publicly before you had a chance to fix it?
A: Please read our stance on coordinated disclosure. In essence, our pledge to you is to respond promptly and fix bugs in a sensible timeframe - and in exchange, we ask for a reasonable advance notice. Reports that go against this principle will usually not qualify, but we will evaluate them on a case-by-case basis.
Q: My report has not been resolved within the first week of submission. Why hasn't it been resolved yet?
A: Reports that deal with potential abuse-related vulnerabilities may take longer to assess, because reviewing our current defense mechanisms requires investigating how a real life attack would take place and reviewing the impact and likelihood requires studying the type of motivations and incentives of abusers of the submitted attack scenario against one of our products.
Q: I wish to report an issue through a vulnerability broker. Will my report still qualify for a reward?
A: We believe that it is against the spirit of the program to privately disclose the flaw to third parties for purposes other than actually fixing the bug. Consequently, such reports will typically not qualify.
Q: What if somebody else also found the same bug?
A: First in, best dressed. You will qualify for a reward only if you were the first person to alert us to a previously unknown flaw.
Q: My employer / boyfriend / dog frowns upon my security research. Can I report a problem privately?
A: Sure. If you are selected as a recipient of a reward, and if you accept, we will need your contact details to process the payment. You can still request not to be listed on our public credits page.
Q: What is bughunter.withgoogle.com?
A: The dashboard for the participants in Google’s VRP program. It dynamically creates the hall of fame, i.e., the 0x0A and honorable mentions lists.
Q: Do I need a profile on bughunter.withgoogle.com to participate in the VRP?
A: No. You can participate in the VRP under the same rules without the need of a profile. However, if you want your name to be listed in the 0x0A or the honorable mentions lists, you need to create a profile.
Q: Is the profile data publicly available?
A: Yes. The profile holds the data that is currently already available now on our hall of fame, i.e., on the 0x0A and honorable mentions lists. You can always leave these fields blank.
Q: How is the honorable mentions list sorted?
A: The hall of fame is sorted based on the volume of valid bug submissions, the ratio of valid vs. invalid submissions, and the severity of those submissions.
Q: My account was disabled after doing some tests. How can I get my account restored?
A: We recommend that you create an account dedicated only to testing before beginning any tests on our products, since we cannot guarantee that you will get access back to your account if it is disabled due to your testing activities. If you accidentally used a non-test account or you suspect your personal account was disabled due to your testing, you can request to have your account restored by Signing in to your Google Account and selecting Try to Restore.
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. 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.
