Background for this topic.
Encryption transforms readable data into ciphertext using an algorithm and a key, so someone who obtains the ciphertext cannot normally understand it without the required key. It protects confidentiality for data in transit, such as traffic between services, and at rest, such as files, databases, and backups. Encryption does not by itself prove who sent data, prevent tampering, or protect plaintext displayed on a compromised endpoint.
Its security therefore depends on implementation and key management. Attackers may target stolen, exposed, or overprivileged keys, weak algorithms or protocols, poor randomness, and systems that decrypt data unnecessarily. Use modern, authenticated encryption where appropriate; protect keys separately from encrypted data with tightly limited access, rotation and revocation procedures, and monitored use. Verify that encryption covers relevant backups and internal service links, while recognizing that lost keys can make recovery impossible and that encrypted traffic may still reveal metadata such as timing or endpoints.

Strong Data Foundations Give AI Leaders an Edge in Quantum SecurityCompanies leading in AI security are also better prepared for quantum threats. New Thales research shows that data visibility, governance, encryption and crypto agility are helping CIOs build stronger foundations for both AI adoption and post-quantum readiness.
Researchers Urge Organizations to Rotate Credentials and Review Audit LogsThreat actor 888 claims it stole Accenture source code and cloud credentials, prompting researchers to warn that any exposed Azure tokens, encryption keys or DevOps secrets could enable follow-on intrusions and downstream supply-chain attacks even as Accenture says operations remain unaffected.
Agencies and Industry Coordinate Post-Quantum Migration PlansThe White House convened government officials, quantum companies and researchers to accelerate the transition to post-quantum cryptography, align public-private investments and reinforce a 2030 deadline as advances in quantum computing increase risks to today's encryption.
Healthcare organizations should prepare for post-quantum cryptography without overreacting to hype, said John Frushour, CISO of New York-Presbyterian Hospital. Stronger encryption standards, commercial software support and attention to medical devices can help providers manage emerging risks.
Fraudsters Tokenize Stolen Cards Into Attacker WalletsGoogle Threat Intelligence Group warned that Chinese-language phishing-as-a-service platforms are using AI, encrypted messaging and real-time OTP interception to bypass multifactor authentication and provision stolen payment cards into attacker-controlled digital wallets worldwide.
Company Pushes Key Rotation After 3,800 Repositories CompromisedHacked code repository GitHub warned administrators of self-hosted git servers to rotate public encryption keys following a May 18 incident involving a poisoned VS Code extension used by an employee. GitHub CISO Alexis Wales in a Tuesday update said the repository is rotating all keys.
Governments Have Long Warned About Kremlin Social Engineering HacksSignal is defending the security of its systems following a series of phishing attacks that took place on the encrypted messaging platform, and that reportedly compromised members of the German government including the president of the country's parliament.
France Invokes Geopolitical Instability to Mandate 2030 DeadlineA working quantum computer is probably at least a decade away. The rush to adopt encryption algorithms that can withstand the onslaught of a qubit attack has already begun, with European countries feeling variable levels of urgency. "Sooner is better in principle," an analyst said.
Dell's John Roese on Quantum Readiness, Cryptographic Inventory and Sovereign AIQuantum computing poses an existential threat to encryption systems built on asymmetric key management protocols, and most enterprises don't know where their cryptographic exposure begins. Dell Technologies' John Roese explains what to do now.
Google's Accelerated PQC Timeline Demands Enterprise Action NowGoogle set a public deadline for migrating to post-quantum cryptography, setting a strong signal for IT and security leaders that they too should transition their encryption into more robust algorithms. Enterprises need a migration strategy now before the window closes.
Cyborg's Nicolas Dupont on Closing the Encrypted Vector Search GapCyborg CEO Nicolas Dupont describes how vector databases concentrate sensitive enterprise data in a structurally unencrypted layer, and conventional encryption can't address the risk without degrading performance.
Alex Doll of Ten Eleven Ventures on Q-Day Risk ConsiderationsQuantum computing advances push security teams to replace encryption keys faster and adopt quantum-resistant algorithms. Investors and enterprises now treat Q-Day as a near-term risk, forcing changes in key management, PKI and cryptographic standards, says Alex Doll of Ten Eleven Ventures.
Fresh Vulnerability Found in Windows AI-Enabled 'Photographic Memory' FeatureMicrosoft's determination to embed the automatic screenshot storage and retrieval feature dubbed Recall into operating systems doesn't appear matched by resolve to make it secure. Researcher Alexander Hagenah said again he's found vulnerabilities in Recall.
'Malicious Server Threat Model' Threatens 'Zero Knowledge Encryption' GuaranteesClaims by leading stand-alone password managers that their implementation of "zero knowledge encryption" means stored passwords can withstand the worst of hacker assaults are vastly overblown, say academic security researchers. They said vendors are in the process of patching the flaws they found.
Futurex's Ruchin Kumar on CBDC Adoption and HSM Security for TransactionsCBDCs are expanding, with 90% of central banks exploring them. India's e-rupee pilot shows strong adoption, backed by RBI standards and HSM-secure transactions. Ruchin Kumar, VP for South Asia at Futurex, underscores awareness, interoperability and encryption as keys to CBDC success and PQC readiness.
FBI Accessed Encrypted Windows Devices Via BitLocker Keys, Microsoft SaysMicrosoft confirmed it handed over BitLocker recovery keys to the FBI in 2025 under court order, raising concerns over cloud-stored encryption keys and whether default designs that prioritize recovery convenience and efficiency weaken user control and security.
University of Hawaii Cancer Center Paid RansomCancer patients who participated in University of Hawaii Cancer Center studies during the 1990s may soon receive a notification that ransomware hackers stole their data in an August 2025 incident. Experts said the hack spotlights concerning risks involving compromises of medical research data.
Chinese-Linked Malware Campaign Targets Critical Environments With Weak MonitoringU.S. and Canadian cyber authorities say Chinese state-backed actors used a backdoor dubbed BRICKSTORM to maintain long-term access into critical infrastructure, exploiting VMware environments to exfiltrate credentials and evade detection through encrypted covert channels.
New Investigatory Powers Act Request Reportedly Transmitted in SeptemberThe U.K. Home Office reportedly again ordered Apple to give it backdoor access to an encrypted cloud service after backing down in August from a similar demand made earlier this year. The order comes after a similar attempt by the Home Office in January.
Tops: Rapidly Acting on Security Software Alerts and Calling in Incident RespondersRapidly acting on security alerts and activating third-party incident response help are the top two ways organizations have successfully arrested an in-progress ransomware attack before it gets to the encryption, according to a review of more than two years' worth of incident response engagements.
