Quantum Computing Threats: Prepare for Post-Quantum Cryptography

Google Calls for Action - PQC Another call for organisations to start their post-quantum cryptographic migrations without haste. Governments, big tech, consultants (big and small practices) and others all agree, the threat of a cryptographically-relevant quantum computer is approaching fast resulting in private and sensitive data at risk. Ashkan Memari and I wrote "Quantum Cybersecurity Program Management" to guide project champions to plan, implement and optimise these quantum technologies and to migrate to post-quantum cryptography from NIST. Pure program management aligned with standards we use everyday. I also wrote "Accelerated Quantum Technologies Change Management" to help organisations break through adoption barriers, update their strategies for quantum and to assess the degree of appropriate schedule compression if any. This is a change management book tuned for today's critical technology projects. With this much emerging project work, it's a great time to be in project management.

Attackers are already preparing for quantum computers that don't fully exist yet. While your organization debates AI budgets, cybercriminals are quietly collecting your encrypted data today—waiting to decrypt it tomorrow with quantum technology. This isn't science fiction. It's happening right now. The strategy is called "harvest now, decrypt later" and it's reshaping how we think about data protection: → Financial records you encrypt today could be readable in 5 years → Government communications secured with RSA won't stay secure forever → Intellectual property protected by current encryption has an expiration date The uncomfortable truth: Most security leaders are still thinking in traditional timelines while attackers are planning decades ahead. Smart organizations aren't waiting for quantum computers to arrive. They're implementing hybrid cryptography strategies that combine today's encryption with quantum-resistant algorithms like ML-KEM. The transition window is closing faster than most realize. Your encrypted data from 2024 might need protection until 2040. Current encryption algorithms might not last that long. But the quantum-safe solutions exist today—if you know where to look. The question isn't whether quantum computing will break encryption. It's whether you'll be ready before it does.

**Someone is stealing your encrypted data right now.** Not to read it today. To decrypt it in 2030 when quantum computers are powerful enough. This is called "Harvest Now, Decrypt Later", and it's not a theory. Intelligence agencies have confirmed it's happening at scale. Q-Day, the moment quantum computers break RSA-2048 encryption, is estimated between 2030 and 2035. Google research now suggests it might take fewer than 1 million qubits. We're currently at hundreds. The gap is closing exponentially. Your sensitive emails from today could be read in 5 years. Your encrypted backups are time capsules waiting to open. Your VPN sessions, API calls, and digital signatures are all vulnerable. Migration to quantum-resistant cryptography takes at least 3-5 years. If Q-Day is 2030 and you start in 2027, you're already compromised. The good news? There are solutions. NIST released the first three post-quantum cryptography standards in August 2024: • ML-KEM (CRYSTALS-Kyber) • ML-DSA (CRYSTALS-Dilithium) • SLH-DSA (SPHINCS+) These aren't experimental. They're production-ready. AWS supports them. Cloudflare has deployed them. Chrome implements them. The challenge? Implementation is brutal. Signature sizes increase 30-40x. Legacy systems break. Hybrid approaches are complex. Every protocol needs updating. The talent pool is tiny. If you're responsible for security and don't have a post-quantum migration plan, you're already behind. Not "behind schedule" behind. Behind, as in "making decisions now that will haunt you in 5 years" behind. Start with a cryptographic inventory. Every API, certificate, encryption operation, and signature. You need complete visibility before you can plan migration. The clock is ticking. Q-Day is coming. The only questions are when and whether you'll be ready. I've written a comprehensive deep dive into post-quantum cryptography, what it means for organisations, and practical steps to prepare. Link in comments. Drop a comment. I'm genuinely curious how many are prepared. #Cybersecurity #QuantumComputing #PostQuantumCryptography #InfoSec #TechLeadership #CISO #CyberSecurity #Innovation #TechTrends #DigitalTransformation

🚨 Hackers are already stealing encrypted data today — because they know quantum computers will break it tomorrow. Let that sink in for a moment. The threat isn’t just about future technology. It’s about data being stolen right now. There’s a strategy quietly spreading in cyber-espionage called: “Harvest Now, Decrypt Later.” The concept is simple. Attackers intercept and store encrypted data today… …and wait for the moment when quantum computers become powerful enough to break current encryption. Why this matters Most of today’s digital security depends on encryption methods like RSA and ECC. They protect things like: • online banking • company intellectual property • healthcare records • government communications With classical computers, breaking these encryption systems would take millions of years. But quantum computers operate differently. Using quantum algorithms, they could potentially break these cryptographic protections dramatically faster. The real risk many organizations overlook Attackers don’t need quantum computers today. Instead they are already doing this: 1️⃣ Stealing encrypted data today 2️⃣ Archiving it for years 3️⃣ Waiting until quantum computing matures This is what security experts call: Harvest Now, Decrypt Later (HNDL) If your data must stay confidential for 10–20 years, it may already be vulnerable. Examples include: • intellectual property • defense and government data • healthcare records • financial histories When quantum capabilities mature, today’s encrypted archives could become readable overnight. 🛡️ How organizations are preparing Two major approaches are emerging: 1️⃣ Post-Quantum Cryptography (PQC) New encryption algorithms designed to resist both classical and quantum attacks. 2️⃣ Quantum Key Distribution (QKD) Uses quantum physics to detect interception of encryption keys instantly. 🚀 What leaders should start doing now • Identify where RSA and ECC are used in your systems • Prioritize protection for long-term sensitive data • Build crypto-agile architectures • Upskill security teams on post-quantum standards Transitioning to quantum-safe security will take years. Organizations that start preparing now will be ready. Those that wait may discover their “secure” data was never secure at all. 💬 Question for the community Do you think organizations are taking the quantum cybersecurity threat seriously enough? #Cybersecurity #QuantumSecurity #PostQuantum #Encryption #CISO #CyberRisk #TechLeadership

OpenClaw is here <> quantum threat isn't coming = FALSE. It's already here. Most organizations just won't know it until 2030. There's a strategy called "Harvest Now, Decrypt Later." State-level adversaries are collecting your encrypted data right now — storing it until quantum computing is powerful enough to break it in the future. Your 2025 contracts. Personnel files. Classified infrastructure. Decrypted in 2030. This isn't hypothetical. It's why NIST finalized post-quantum cryptography standards in 2024. And yet most enterprises are still running RSA and ECC — encryption that a quantum computer will break in hours. Jim Smid, principal architect for DoD and the Intelligence Community at Palo Alto Networks, said it plainly at the federal Cyber Leaders Exchange: "In a PQC world, you can't have zero trust if the data itself can be collected and decrypted later. It needs to be a huge priority." A GDIT study backs this up: 46% of federal IT leaders have identified cryptographic risks — but haven't started formal assessments. Here's the assumption I want to challenge: "We'll migrate when quantum is actually a threat." The data being harvested right now is the threat. 4 things organizations consistently get wrong: → Treating PQC as an IT upgrade instead of a board-level risk decision → Assuming vendors have handled it (most haven't even assessed it) → Underestimating how deep cryptographic dependencies run in legacy systems → Confusing "quantum-safe storage" with end-to-end quantum-resistant architecture I work closely with teams building cryptographic infrastructure at the intersection of ZK proofs, post-quantum security, and real-world deployment at scale. It's a valid threat that needs to remain a priority in this Agentic AI race + (insert new buzzword tech). ― I am curious where your organization stands on this. Has your security team mapped your cryptographic dependencies yet — or is PQC still waiting for budget approval? #PostQuantum #CyberSecurity #NationalSecurity #ZeroTrust #Cryptography

🚨 The 'Year of Quantum Security' is HERE. Google just broke quantum computing (in a good way for science, bad for your data). Is your business ready for the inevitable encryption crisis? Google's recent demonstration of below-threshold quantum error correction is not just a scientific footnote; it's a critical accelerator. This moves quantum computing from theoretical research to scalable engineering, making the threat to current encryption protocols a near-term reality, not a distant sci-fi concept. The "harvest now, decrypt later" threat is no longer theoretical. Adversaries are already collecting encrypted data, knowing that future quantum machines could unlock it. This means your sensitive information, secured today, might be compromised tomorrow. The window for proactive defense is closing rapidly. Industry analysis suggests a crucial 24-36 month migration mandate for post-quantum cryptography. This isn't just an IT upgrade; it's a fundamental cybersecurity imperative. Delay is no longer an option when the integrity of your long-term data is at stake. Businesses must re-evaluate their entire encryption posture, from communications to stored data. Integrating quantum-safe algorithms needs to be a top-tier priority in your cybersecurity roadmap. Are you treating this as the urgent, significant threat it truly is? #QuantumComputing #Cybersecurity #QuantumSafe #Encryption #FutureTech

⚛️ Google's Urgent Warning: Quantum Computing Is Now a Real Cybersecurity Threat On February 7, 2026, Google issued a stark warning: "Store Now, Decrypt Later" (SNDL) attacks are already underway — and your encrypted data is at risk RIGHT NOW. Here's what every security leader needs to understand: 🔐 What is "Store Now, Decrypt Later"? Adversaries are actively harvesting and stockpiling your encrypted data today — financial records, classified communications, trade secrets — with the plan to decrypt everything once quantum computers become powerful enough. This isn't theoretical. It's happening NOW. 📊 The Quantum Threat Landscape: • Quantum computers are reaching "cryptographically relevant" thresholds • RSA-2048 and elliptic curve cryptography (ECC) are most at risk • Google has already migrated its services to quantum-resistant encryption (ML-KEM) • NIST finalized post-quantum cryptography standards in August 2024 • Full quantum decryption capabilities still 5-10 years away — but SNDL starts today 🎯 What Data Is Most at Risk? 1. Healthcare records (must stay confidential for decades) 2. Financial transaction histories 3. Defense and intelligence communications 4. Intellectual property and trade secrets 5. Long-term contracts and legal documents ✅ What Organizations Should Do NOW: → Conduct a cryptographic inventory — know where RSA/ECC is used → Begin migrating to NIST-approved post-quantum algorithms (CRYSTALS-Kyber, CRYSTALS-Dilithium) → Prioritize data with long confidentiality requirements → Work with vendors to understand their PQC roadmaps → Implement crypto-agility so future algorithm swaps are easier Kent Walker (Google): "A cryptographically relevant quantum computer is no longer perpetually a decade away." The window to act is NOW — before the quantum breakthrough arrives. 🔗 Source: Google/Kiteworks analysis https://lnkd.in/enmiDm87 #QuantumComputing #PostQuantumCryptography #Cybersecurity #Encryption #FractionalCISO #InfoSec #NIST #CryptoAgility

Expert Recommends: Prepare for PQC Right Now Introduction: Steal It Today, Break It in a Decade Digital evolution is unstoppable, and though the pace may vary, things tend to fall into place sooner rather than later. That, of course, applies to adversaries as well. The rise of ransomware and cyber extortion generated funding for a complex and highly professional criminal ecosystem. The era of the cloud brought general availability of almost infinite amounts of storage. So there is literally nothing that stops criminals from stealing and trafficking heaps of data, be it encrypted or not. Patient adversaries are employing a "Harvest Now, Decrypt Later" (HNDL) strategy. They are quietly accumulating encrypted data with the intention of decrypting it later using quantum computers. Any data requiring long-term security, such as trade secrets or classified designs, is vulnerable because its lifespan will inevitably outlive its current encryption. Therefore, it is crucial that organizations begin planning their PQC migration now, ensuring that data encrypted today remains secure against future quantum-enabled decryption attacks. https://lnkd.in/eaDBTnu3 Please follow Divye Dwivedi for such content.  #DevSecOps,#SecureDevOps,#CyberSecurity,#SecurityAutomation,#CloudSecurity,#InfrastructureSecurity,#DevOpsSecurity,#ContinuousSecurity, #SecurityByDesign, #SecurityAsCode, #ApplicationSecurity,#ComplianceAutomation,#CloudSecurityPosture, #SecuringTheCloud,#AI4Security #DevOpsSecurity #IntelligentSecurity #AppSecurityTesting #CloudSecuritySolutions #ResilientAI #AdaptiveSecurity #SecurityFirst #AIDrivenSecurity #FullStackSecurity #ModernAppSecurity #SecurityInTheCloud #EmbeddedSecurity #SmartCyberDefense #ProactiveSecurity

BLACK3P TECHNOLOGIES 🇺🇲 🇬🇧 Specializing in the field of CYBER SECURITY DEFENSE Proposes the study of the transition to encryption resistant to PQC quantum attacks by 2035. contact@black3p.com 🇬🇧🇺🇲 The “transition to encryption resistant to PQC quantum attacks by 2035” means: ➡️ The global migration to cryptography systems capable of resisting quantum computers by 2035. Here's the simple explanation. 1. Why this transition is necessary Today, most security systems use algorithms like: RSA ECC (Elliptic Curve Cryptography) Diffie-Hellman These methods protect: banks military communications the Internet (HTTPS) emails government systems But future quantum computers will be able to break these algorithms very quickly thanks to massively parallel computing. NCSC 2. The problem: “Q-Day” Experts talk about Q-Day: 👉 the day a quantum computer will be powerful enough to break current encryption. Possible consequences: Decryption of diplomatic communications Attacks on banks Massive espionage Compromise of critical infrastructure Some data can even be stolen today and decrypted later (“harvest now, decrypt later”). TechRadar. 3. The solution: PQC (Post-Quantum Cryptography) Governments and organizations like the National Institute of Standards and Technology (NIST) are developing new algorithms resistant to quantum computers. NIST Examples of PQC algorithms: ML-KEM (formerly Kyber) ML-DSA (formerly Dilithium) SLH-DSA These algorithms are designed to remain secure even if a quantum computer exists. 4. Why the 2035 Deadline? Cybersecurity agencies (Europe, USA, UK, NSA) have set a global timeline: Recommended Timeline: 2026-2028 System audit and migration plan 2028-2031 Gradual replacement of critical systems 2035 All systems must use PQC. NCSC +1 After 2035, vulnerable algorithms like RSA will be banned or obsolete in many systems. AppViewX. 5. Most Affected Sectors The transition concerns: Defense Banking Satellites Government Communications Cloud and Internet IoT and Critical Infrastructure. ✅ In Summary The phrase means: The world must replace current encryption systems with quantum-resistant cryptography before 2035 to prevent these machines from breaking global digital security. contact@black3p.com copyright#BLACK3P#2026
