Quantum computing is one of the most exciting technological frontiers of our time. It promises to revolutionize fields like medicine, logistics, and artificial intelligence. However, significant authority necessitates a corresponding level of accountability and entails potential risk. One of the most overlooked dangers in the race to build powerful quantum computers isn’t just what outsiders might do with them. It’s what insiders might do.
Imagine this: a researcher working late at a cutting edge quantum lab, surrounded by machines capable of calculations that would take classical computers billions of years. What if that person decided to use the lab’s quantum computer not for science, but for theft? What if they quietly ran an algorithm to crack the encryption on a cryptocurrency wallet and walked away with millions?
The Rise of Quantum Computing and the Encryption Problem
Most of today’s digital security relies on cryptography. Whether it’s your bank account, your email, or your cryptocurrency wallet, encryption keeps your data safe. But quantum computers are built to solve the very math problems that make this encryption work.
Algorithms like RSA and elliptic-curve cryptography (ECC) are considered secure because they’re hard to break with classical computers. But quantum algorithms like Shor’s can crack them much faster. Experts estimate that a quantum computer capable of breaking RSA-2048 encryption could be just 10 to 20 years away. Some even think it could happen sooner.
This looming threat has led to a global push for post-quantum cryptography, new algorithms that can withstand quantum attacks. But the transition is slow, and many systems still rely on vulnerable encryption.
The Insider Threat: A New Kind of Risk
When we think of cyber threats, we often picture hackers in hoodies breaking into systems from afar. But insiders, people who already have access, pose a different kind of danger. They don’t need to break in. They’re already inside.
In quantum labs, insiders might be researchers, technicians, or IT staff. They have access to the machines, the data, and the systems. If one of them decided to misuse a quantum computer, they could do serious damage before anyone even noticed.
Let’s explore how this could play out.
Scenario One: The Quantum Crypto Heist
Cryptocurrency is a tempting target. It’s decentralized, anonymous, and often worth a lot of money. The Human Rights Foundation recently warned that around 6.5 million bitcoins, about one-third of all BTC, could be vulnerable to quantum attacks. That includes 1.1 million coins believed to be held by Bitcoin’s mysterious creator, Satoshi Nakamoto.
Here’s how an insider could pull off a quantum-powered crypto heist:
- They identify Bitcoin addresses with known public keys. These are often older addresses or ones that have been reused.
- Using the lab’s quantum computer, they run Shor’s algorithm to derive the private keys from those public keys.
- With the private keys in hand, they sign transactions to transfer the funds to their own wallet.
- They do all of this quietly, possibly during off-hours, and disguise the job as a routine experiment.
- They export the results offline, avoiding network monitoring, and execute the theft from an external device.
Because the insider is operating within a trusted environment, their actions might not trigger any alarms. The theft only becomes visible when the stolen coins start moving on the blockchain. Even then, it might take time before anyone suspects a quantum attack.
Scenario Two: Decrypting Sensitive Data
Another possibility is espionage. Governments and companies store encrypted data, assuming it’s safe. But an insider with quantum access could decrypt that data years before anyone expects it.
They might target:
- Classified government files
- Intellectual property
- Intercepted communications
- Encrypted backups
Because the data is encrypted, organizations might not monitor access closely. The insider could read sensitive information without raising suspicion. If they leak or sell the data, the breach might never be traced back to them.
Scenario Three: Forging Digital Signatures
Digital signatures are used to verify identity and authenticity. They’re critical for software updates, secure communications, and financial transactions. If an insider uses a quantum computer to forge a signature, they could impersonate executives, issue fake commands, or distribute malware disguised as trusted software.
Encryption Consulting warns that attackers could fake software updates and impersonate anyone digitally. An insider would know exactly which keys to target for maximum impact. They could forge a CEO’s signature, authorize fraudulent transactions, or issue fake certificates that compromise entire systems.
Why It’s So Hard to Detect
Insider quantum attacks are stealthy. The insider uses legitimate access, runs computations that look like normal research, and avoids network monitoring by keeping everything offline. They might disable logs, work during quiet hours, and cover their tracks.
Even when the consequences become visible, like stolen cryptocurrency or leaked data, it’s hard to trace the attack back to the insider. The quantum computer doesn’t leave fingerprints. It just does math.
What Can Be Done?
Preventing insider quantum attacks requires a mix of technical controls, policy changes, and cultural shifts.
1. Secure Quantum Labs
Treat quantum computers like high security assets. Implement role based access controls, two person rules for sensitive operations, and immutable logging. Use behavior analytics to detect unusual activity, like a researcher accessing systems at odd hours or running large computations without explanation.
2. Limit Data Exposure
Don’t assume encrypted data is safe. Use the principle of least privilege. Store critical keys in hardware security modules. Rotate keys frequently. Monitor access to encrypted files, even if they’re not supposed to be readable.
3. Migrate to Post-Quantum Cryptography
Start transitioning to quantum resistant algorithms now. The fewer vulnerable systems, the less attractive the target. Use lattice based or hash based cryptography for signatures and encryption. It’s a long process, but every step reduces risk.
4. Strengthen Insider Threat Programs
Train staff to recognize signs of insider misuse. Update threat models to include quantum scenarios. Encourage reporting of suspicious behavior. Vet employees carefully, especially those with access to quantum hardware.
5. Conduct External Audits
Bring in outside experts to review quantum job logs and system usage. Use honeytokens, fake data or keys, to detect unauthorized access. Mirror logs to secure servers that insiders can’t tamper with.
6. Build an Ethical Culture
Remind researchers of their responsibilities. Emphasize the consequences of misuse. Foster a culture of transparency and accountability. Make it clear that quantum computing is powerful and that power must be used responsibly.
Final Thoughts
Quantum computing is a game changer. It’s going to unlock incredible possibilities. But it also introduces new risks, especially from insiders who have early access to this technology.
We’ve already seen what happens when insiders misuse powerful machines. In 2018, Russian scientists were caught using a nuclear supercomputer to mine Bitcoin. They were only discovered because they tried to connect the machine to the internet. A quantum insider wouldn’t need to do that. They could operate entirely offline, making detection even harder.
The good news is that we still have time. Quantum computers capable of breaking encryption aren’t here yet. But they’re coming. By acting now: securing labs, migrating to post-quantum cryptography, and updating insider threat programs we can stay ahead of the risk.
The quantum revolution is exciting. Let’s make sure it’s also safe.
