Apple Doubles Bug Bounty Maximum Payout to $2 Million for Zero-Click Remote Code Execution Vulnerabilities

Apple has announced a comprehensive expansion and restructuring of its security bug bounty program, doubling maximum payouts to $2 million and introducing new vulnerability categories targeting sophisticated attack techniques. The enhanced program reflects escalating concerns about mercenary spyware targeting high-risk individuals and organizations.

Since launching in 2020, Apple’s bug bounty initiative has distributed $35 million across 800 security researchers, with individual reports previously commanding up to $500,000. The new framework substantially increases rewards across multiple vulnerability categories while maintaining bonus structures that can elevate total payouts beyond $5 million for specific high-value discoveries.

The expansion positions Apple’s program among the most lucrative in the technology industry, potentially reshaping the economics of vulnerability research and mercenary spyware development. By offering competitive financial incentives, Apple aims to encourage researchers to responsibly disclose vulnerabilities rather than sell exploits to commercial surveillance vendors.

Zero-Click Remote Exploits Command Highest Rewards

The program’s top-tier reward targets zero-click remote code execution vulnerabilities—exploits requiring no user interaction to compromise a device. These represent the most sophisticated and dangerous attack vectors, frequently deployed in mercenary spyware campaigns against journalists, activists, and political figures.

“This is an unprecedented amount in the industry and the largest payout offered by any bounty program we’re aware of – and our bonus system, providing additional rewards for Lockdown Mode bypasses and vulnerabilities discovered in beta software, can more than double this reward, with a maximum payout in excess of $5 million,” Apple stated.

The $2 million base reward for zero-click exploits reflects their rarity and technical complexity. Successfully chaining multiple vulnerabilities to achieve remote code execution without user interaction requires exceptional expertise and represents the capability level of nation-state actors and commercial spyware vendors.

Apple’s bonus system can amplify rewards substantially. Vulnerabilities that bypass Lockdown Mode—Apple’s enhanced protection feature for high-risk users—or discoveries made in beta software qualify for additional compensation, potentially exceeding $5 million total for a single comprehensive disclosure.

Expanded Reward Structure Addresses Diverse Attack Vectors

Apple has introduced or increased payouts across multiple vulnerability categories, reflecting the diverse techniques adversaries employ to compromise devices and access user data:

High-Value Categories:

  • One-click remote attack requiring user interaction: $1,000,000
  • Wireless proximity attack: $1,000,000
  • Broad unauthorized iCloud access: $1,000,000
  • WebKit exploit chain enabling unsigned arbitrary code execution: $1,000,000

Medium-Value Categories:

  • Attack on locked device with physical access: $500,000
  • App sandbox escape: $500,000
  • One-click WebKit sandbox escape: $300,000

Specialized Categories:

  • macOS Gatekeeper complete bypass with no user interaction: $100,000
  • Encouragement award for low-impact but valid reports: $1,000

The tiered structure acknowledges varying exploitation complexity and real-world impact. Vulnerabilities enabling broad iCloud access or complete Gatekeeper bypasses without user interaction have never been reported to Apple, suggesting these represent particularly challenging research targets with correspondingly high rewards.

Wireless Proximity Attacks Receive Substantial Increase

Apple highlighted the wireless proximity attack category, which has been elevated from $250,000 to $1,000,000. The company notes it has “never observed a real-world, zero-click attack executed purely through wireless proximity,” underscoring both the theoretical nature of this threat and the substantial reward for demonstrating feasibility.

The category now encompasses additional Apple-developed wireless components, including C1 and C1X modems and the N1 wireless chip. This expansion reflects Apple’s growing in-house silicon development and the corresponding need to ensure these proprietary components meet rigorous security standards.

Wireless proximity attacks represent a particularly concerning threat vector because they require only physical proximity to a target device without network connectivity or user interaction. Successfully demonstrating such capabilities would have significant implications for protecting high-risk individuals in sensitive environments.

Security Research Devices Target Civil Society Protection

For 2026, Apple plans to distribute one thousand secured iPhone 17 devices to members of civil society organizations identified as higher risk for mercenary spyware targeting. These devices will simultaneously support Apple’s Security Research Device Program, with applications accepted through October 31.

This initiative recognizes that journalists, human rights defenders, political dissidents, and other civil society members face disproportionate targeting from sophisticated surveillance tools. By providing specialized research devices to both potential targets and security researchers, Apple aims to strengthen defenses against commercial spyware operations.

The Security Research Device Program provides researchers with modified hardware offering deeper system access for vulnerability research while maintaining isolation from production devices. This approach balances the need for thorough security testing against the risks of providing unrestricted access to Apple’s security mechanisms.

Strategic Implications for Spyware Economics

Apple explicitly acknowledges that enhanced bounty rewards aim to impact the economics of sophisticated attack chain development. By offering competitive compensation for vulnerability disclosure, the company seeks to influence researchers’ calculations when considering whether to report findings or sell to spyware vendors.

“The tech giant expects that the increased awards will have an additional impact on the development of sophisticated attack chains from spyware vendors, as researchers will be more incentivized to find and report security issues,” according to the announcement.

This strategic approach recognizes that commercial spyware vendors rely on acquiring or developing zero-day vulnerabilities to maintain effectiveness. If Apple can successfully incentivize more researchers to disclose rather than sell, it potentially constrains the vulnerability supply available to surveillance vendors.

However, the effectiveness of this strategy depends on whether Apple’s rewards remain competitive with prices offered by exploit brokers and spyware vendors. While $2 million represents substantial compensation, reports suggest that zero-click iOS exploits have commanded higher prices in commercial markets, particularly for capabilities that evade Apple’s latest protections.

Enhanced Security Measures Complement Bounty Program

The bounty expansion accompanies ongoing development of iOS security features designed to raise the cost and complexity of spyware attacks. Apple has implemented advanced protection measures including Lockdown Mode and Memory Integrity Enforcement, which make developing and executing stealthy spyware attacks significantly more expensive.

Lockdown Mode, introduced for high-risk users, substantially restricts device functionality to minimize attack surface. Features like message attachments, link previews, and complex web technologies are limited or disabled, prioritizing security over convenience for users facing elevated threats.

Memory Integrity Enforcement and other low-level protections harden the operating system against exploitation techniques commonly employed in sophisticated attacks. By making exploitation more difficult, Apple forces adversaries to invest more resources in developing and maintaining effective attack chains.

The combination of technical defenses and economic incentives through the bug bounty program represents a comprehensive strategy to protect users from commercial surveillance. Technical barriers increase attack development costs while financial rewards encourage disclosure rather than exploitation.

Industry Context and Competitive Positioning

Apple’s expanded bounty program occurs within a broader industry context of escalating concerns about commercial spyware and the vulnerability marketplaces that enable surveillance operations. Technology companies increasingly recognize that defensive security measures alone cannot fully protect users against well-resourced adversaries with access to previously unknown vulnerabilities.

Bug bounty programs have become standard across the technology industry, though payout structures and program scope vary significantly. Apple’s announcement of industry-leading rewards may pressure competitors to enhance their own programs, potentially reshaping the broader vulnerability research landscape.

The program’s emphasis on protecting civil society organizations also reflects growing awareness of how commercial spyware targeting extends beyond traditional national security contexts. Journalists, activists, lawyers, and other civil society members face sophisticated surveillance that threatens fundamental rights including press freedom and political expression.

Looking forward, the program’s success will be measured not only by the quantity and quality of vulnerability reports received but also by whether it meaningfully impacts the commercial spyware industry’s operational capabilities. If successful, Apple’s approach could provide a model for other technology companies seeking to protect high-risk users from targeted surveillance.

The expanded bug bounty program represents a significant commitment of resources to security research and vulnerability disclosure. Whether these enhanced incentives prove sufficient to substantially impact the spyware ecosystem remains an open question that will unfold as researchers respond to the new reward structure and Apple implements the associated security improvements.
