In 2024, our Vulnerability Reward Program confirmed the ongoing value of engaging with the security research community to make Google and its products safer. This was evident as we awarded just shy of $12 million to over 600 researchers based in countries around the globe across all of our programs.

VRP Highlights in 2024

In 2024 we made a series of changes and improvements coming to our vulnerability reward programs and related initiatives:

• The Google VRP revamped its reward structure, bumping rewards up to a maximum of $151,515, the Mobile VRP is now offering up to $300,000 for critical vulnerabilities in top-tier apps, Cloud VRP has a top-tier award of up $151,515, and Chrome awards now peak at $250,000 (see the below section on Chrome for details).

• We rolled out InternetCTF – to get rewarded, discover novel code execution vulnerabilities in open source and provide Tsunami plugin patches for them.

• The Abuse VRP saw a 40% YoY increase in payouts – we received over 250 valid bugs targeting abuse and misuse issues in Google products, resulting in over $290,000 in rewards.

• To improve the payment process for rewards going to bug hunters, we introduced Bugcrowd as an additional payment option on bughunters.google.com alongside the existing standard Google payment option. 

• We hosted two editions of bugSWAT for training, skill sharing, and, of course, some live hacking – in August, we had 16 bug hunters in attendance in Las Vegas, and in October, as part of our annual security conference ESCAL8 in Malaga, Spain, we welcomed 40 of our top researchers. Between these two events, our bug hunters were rewarded $370,000 (and plenty of swag).

• We doubled down on our commitment to support the next generation of security engineers by hosting four init.g workshops (Las Vegas, São Paulo, Paris, and Malaga). Follow the Google VRP channel on X to stay tuned on future events.

More detailed updates on selected programs are shared in the following sections.

Android and Google Devices

In 2024, the Android and Google Devices Security Reward Program and the Google Mobile Vulnerability Reward Program, both part of the broader Google Bug Hunters program, continued their mission to fortify the Android ecosystem, achieving new heights in both impact and severity. We awarded over $3.3 million in rewards to researchers who demonstrated exceptional skill in uncovering critical vulnerabilities within Android and Google mobile applications. 

The above numbers mark a significant change compared to previous years. Although we saw an 8% decrease in the total number of submissions, there was a 2% increase in the number of critical and high vulnerabilities. In other words, fewer researchers are submitting fewer, but more impactful bugs, and are citing the improved security posture of the Android operating system as the central challenge. This showcases the program's sustained success in hardening Android.

This year, we had a heightened focus on Android Automotive OS and WearOS, bringing actual automotive devices to multiple live hacking events and conferences. At ESCAL8, we hosted a live-hacking challenge focused on Pixel devices, resulting in over $75,000 in rewards in one weekend, and the discovery of several memory safety vulnerabilities. To facilitate learning, we launched a new Android hacking course in collaboration with external security researchers, focused on mobile app security, designed for newcomers and veterans alike. Stay tuned for more.

We extend our deepest gratitude to the dedicated researchers who make the Android ecosystem safer. We're proud to work with you! Special thanks to Zinuo Han (@ele7enxxh) for their expertise in Bluetooth security, blunt (@blunt_qian) for holding the record for the most valid reports submitted to the Google Play Security Reward Program, and WANG,YONG (@ThomasKing2014) for groundbreaking research on rooting Android devices with kernel MTE enabled. We also appreciate all researchers who participated in last year's bugSWAT event in Málaga. Your contributions are invaluable! 

Chrome

Chrome did some remodeling in 2024 as we updated our reward amounts and structure to incentivize deeper research. For example, we increased our maximum reward for a single issue to $250,000 for demonstrating RCE in the browser or other non-sandboxed process, and more if done directly without requiring a renderer compromise. 

In 2024, UAF mitigation MiraclePtr was fully launched across all platforms, and a year after the initial launch, MiraclePtr-protected bugs are no longer being considered exploitable security bugs. In tandem, we increased the MiraclePtr Bypass Reward to $250,128. Between April and November, we also launched the first and second iterations of the V8 Sandbox Bypass Rewards as part of the progression towards the V8 sandbox, eventually becoming a security boundary in Chrome. 

We received 337 reports of unique, valid security bugs in Chrome during 2024, and awarded 137 Chrome VRP researchers $3.4 million in total. The highest single reward of 2024 was $100,115 and was awarded to Mickey for their report of a MiraclePtr Bypass after MiraclePtr was initially enabled across most platforms in Chrome M115 in 2023. We rounded out the year by announcing the top 20 Chrome VRP researchers for 2024, all of whom were gifted new Chrome VRP swag, featuring our new Chrome VRP mascot, Bug.

Cloud VRP

The Cloud VRP launched in October as a Cloud-focused vulnerability reward program dedicated to Google Cloud products and services. As part of the launch, we also updated our product tiering and improved our reward structure to better align our reports with their impact on Google Cloud. This resulted in over 150 Google Cloud products coming under the top two reward tiers, enabling better rewards for our Cloud researchers and a more secure cloud.

Since its launch, Google Cloud VRP triaged over 400 reports and filed over 200 unique security vulnerabilities for Google Cloud products and services leading to over $500,000 in researcher rewards. 

Our highlight last year was launching at the bugSWAT event in Málaga where we got to meet many of our amazing researchers who make our program so successful! The overwhelming positive feedback from the researcher community continues to propel us to mature Google Cloud VRP further this year. Stay tuned for some exciting announcements!

Generative AI

We’re celebrating an exciting first year of AI bug bounties.  We received over 150 bug reports – over $55,000 in rewards so far – with one-in-six leading to key improvements. 

We also ran a bugSWAT live-hacking event targeting LLM products and received 35 reports, totaling more than $87,000 – including issues like “Hacking Google Bard - From Prompt Injection to Data Exfiltration” and “We Hacked Google A.I. for $50,000”.

Keep an eye on Gen AI in 2025 as we focus on expanding scope and sharing additional ways for our researcher community to contribute. 

Looking Forward to 2025

In 2025, we will be celebrating 15 years of VRP at Google, during which we have remained fully committed to fostering collaboration, innovation, and transparency with the security community, and will continue to do so in the future. Our goal remains to stay ahead of emerging threats, adapt to evolving technologies, and continue to strengthen the security posture of Google’s products and services. 

We want to send a huge thank you to our bug hunter community for helping us make Google products and platforms more safe and secure for our users around the world – and invite researchers not yet engaged with the Vulnerability Reward Program to join us in our mission to keep Google safe! 

Thank you to Dirk Göhmann, Amy Ressler, Eduardo Vela, Jan Keller, Krzysztof Kotowicz, Martin Straka, Michael Cote, Mike Antares, Sri Tulasiram, and Tony Mendez.
