SpaceX Increases Reward for Security Vulnerabilities in Starlink Link to $100,000 for Skilled Hackers
SpaceX's bug bounty program for its Starlink satellite internet service has proven to be a valuable asset in identifying and addressing potential security issues. The program, launched in 2022, offers rewards up to $100,000 for identifying critical vulnerabilities in the Starlink network and hardware [1].
In a recent development, researchers have discovered a critical flaw in the CryptoLib encryption library used by many satellites, including Starlink. This vulnerability allows unauthenticated packets to crash the onboard software and reset keys, potentially leading to a zero-key state for secure communication [1]. SpaceX has promptly addressed these vulnerabilities, ensuring they have been patched [1].
Beyond the CryptoLib issue, the program has uncovered dozens of vulnerabilities in Starlink to date. However, specific details on each vulnerability beyond the critical onboard software crash issue are not publicly enumerated [3].
The Starlink bug bounty program has two main categories: software vulnerabilities and hardware systems. Researchers can earn between $100 and $50,000 for uncovering software vulnerabilities, while if a hardware bug has the potential to compromise critical systems or enable persistent access, researchers could receive up to $100,000 [1].
The program has strict guidelines in place to prevent abuse. Hackers testing in the Starlink program must only use hardware they personally own and should avoid disrupting service for other users [1]. Any discovery of a potential satellite-level vulnerability must be immediately reported [1].
Bugcrowd, the platform managing the Starlink bug bounty program, reviews 75% of reported vulnerabilities within two days [1]. The hardware side of the bug bounty program evaluates vulnerabilities in Starlink antenna, routers, or backend infrastructure on a case-by-case basis [1].
The Starlink bug bounty program has already paid out for over 100 vulnerabilities [1]. Recent average payouts for discoveries in the Starlink program are around US$1,000 [1]. It's important to note that no new information about the rewards structure for the bug bounty program was provided [1].
This information reflects the latest known reports as of August 2025 [1][3]. While the discovery of these vulnerabilities is concerning, it's reassuring to know that SpaceX is actively addressing these issues through its bug bounty program. The program underscores SpaceX's commitment to maintaining the security and reliability of its Starlink satellite internet service.

- The Starlink bug bounty program, managed by Bugcrowd, encompasses both software vulnerabilities and hardware systems, with rewards ranging from $100 to $100,000 for significant findings in these areas.
- In addition to the critical CryptoLib encryption library vulnerability, the Starlink bug bounty program has uncovered and addressed over 100 vulnerabilities since its launch in 2022, underscoring SpaceX's commitment to maintaining the security and reliability of its space-and-astronomy, technology, and cybersecurity infrastructure.
