Neuralink and cybersecurity: is it possible to hack the chip implanted in humans?
As technological innovations advance, new questions arise, especially in sensitive areas such as brain-computer interfaces. Elon Musk's company Neuralink is one of the pioneers in this field, developing brain chips that promise to revolutionize communication between the human brain and digital devices.
However, a crucial question has been raised: is it possible to hack these chips?
What do experts say about the security of Neuralink's chip?
Noland Arbaugh, the first patient to receive a Neuralink brain implant, has become a focal point of this discussion. On January 28, 2024, Arbaugh, who was paralyzed after an accident in 2016, received the chip and has since demonstrated the ability to control a computer cursor using only his thoughts.
While the advances are remarkable, he himself admits that, yes, the chip can be hacked, but the possible damage is limited.
In an interview with Joe Rogan, Arbaugh noted that a hacker could, at most, access brain signals, view data collected by Neuralink, or control the cursor on the screen. “But that’s it,” he said, downplaying the risks.
Cybersecurity Outlook: Real Risks or Exaggeration?
Despite Arbaugh’s apparent optimism, cybersecurity experts such as Roger Grimes have taken a more cautious view. Grimes, who has more than 35 years of experience in the field, emphasizes that any implanted medical device can be vulnerable to attack.
“Why would Neuralink’s chip be any different?” he asks. According to Grimes, history shows that most implanted devices, from pacemakers to insulin pumps, can be compromised by hackers.
Still, hacking the Neuralink chip would not be a simple task. For Grimes, it would require the hacker to be physically close to the device, in addition to having detailed technical knowledge about how it works.
The lack of direct internet connectivity is one of the main factors that hinder cyberattacks, making the device less susceptible to remote attackers. In addition, the chip uses a specific operating system, which is probably not popular, which further reduces the risk of attacks using traditional hacking methods.

The possible consequences of a hacker attack on the Neuralink chip
While the risk of a cyberattack on Neuralink’s chip is low, the potential consequences of a successful hack cannot be ignored. According to Grimes, if a hacker were to gain control of the chip, it could potentially put the user’s life at risk, depending on the functions the device controls.
This is particularly concerning in cases where the chip is used to restore critical motor or cognitive functions. For example, an attack that interferes with the user's ability to control their movements could result in serious or even fatal injuries.
However, it's important to note that Grimes did not provide details on the specific scenarios in which these consequences could occur, leaving a significant gap in the debate over the safety of Neuralink's devices.
The challenges of protecting implanted medical devices
The security of implanted medical devices, such as Neuralink’s chip, poses an ongoing challenge for engineers and cybersecurity experts.
The lack of direct internet connectivity is a significant advantage, but it does not completely eliminate risks. Cutting-edge technologies like these require additional layers of security to protect the sensitive data they collect and process.
Furthermore, the medical and scientific community needs to be vigilant and proactive, conducting regular audits and constantly updating systems to mitigate any new threats that may emerge.
Collaboration between medical device manufacturers, cybersecurity experts and regulators is essential to ensure these devices remain secure as they become more integrated into users’ lives.
Brain chip security is a work in progress
While Neuralink's chip represents a significant advance in brain-computer interfacing, the issue of cybersecurity cannot be underestimated.
While experts like Roger Grimes warn of the potential risks, the current landscape suggests that while it is technically possible to hack the device, the technical challenges make this task extremely difficult. However, as the technology evolves and becomes more widely adopted, continued vigilance and security updates will be crucial to protect users from potential threats.
So while the future of brain-computer interfaces looks promising, the security of these devices is still a rapidly evolving field, where innovation must always be accompanied by caution.
