When we communicate online today – from your personal emails and DMs to secure international commerce – we usually do so with encryption. Encryption converts readable data into unreadable gibberish to protect our privacy and security. This didn’t just happen organically. Three decades ago, the U.S government treated encryption like a weapon, and it took some unlikely heroes to set it free: a grad student, a junior la…
It was discovered that some AMD processors did not properly perform Reverse Map Table (RMP) checks when the IOMMU accessed certain host buffers. A local attacker with hypervisor access could possibly use this to trigger an out-of-bounds condition and compromise the integrity of SEV-SNP guest memory. (CVE-2023-20585) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to c…
Lattice Semiconductor has released version 5.0 of its Lattice Sentry solution stack, adding post-quantum cryptography (PQC) to its platform firmware resilience (PFR) and attestation capabilities. The update provides CNSA 2.0-aligned, NIST-compliant protection for AI data centers and critical infrastructure, giving system designers a validated, production-ready approach to quantum-resistant security. “AI infrastructur…
It is tempting to think of Windows in terms of a simple model: user mode and kernel mode. If a bug lets a user-mode process gain control of the kernel, it’s game over. Well, for a long time it used to be like that. Protected processes, SMEP, PatchGuard and other mitigations surely raised the bar, but it was Virtualization-Based Security that added another dimension to that model and made the whole design a lot more c…
You want to set a cryptographic algorithm policy and stop non-compliant choices from being made in your Amazon Web Services (AWS) environment. This post shows you how. As you adopt post-quantum cryptography, one of the first decisions you face is which algorithms and parameter sets fit your business needs, balancing security against signature size, key […]
The acquisition pairs Elisity's zero-trust access controls with IonQ's post-quantum cryptography business as federal agencies and major companies accelerate timelines for quantum-ready encryption. The post IonQ to buy zero-trust security firm Elisity in deal valued at up to $1.3 billion appeared first on CyberScoop.
If you run a website, you’ve already met encryption even if you’ve never used the word. It’s the 🔒 padlock in the browser bar, the reason your host told you to stop using plain FTP, and the checkbox on your backup settings that says “encrypt archive.” Encryption is one of the few security controls that works quietly and almost never needs your attention, which is exactly why it’s easy to misunderstand. Plenty of site…
Year after year CISOs see the volume, velocity, and sophistication of attacks increase. They also see their attack surfaces expand and increase in complexity. Advances in artificial intelligence and the rapid growth of AI use in business are also impacting the security agenda, introducing novel attacks, broadening the attack surface to include AI infrastructure, and presenting governance and security control challeng…
Websites that rely on Let’s Encrypt will soon have to renew their TLS certificates more often. Starting February 10, 2027, the certificate authority will issue certificates valid for 64 days by default, down from 90 days. Subscribers who already use Let’s Encrypt’s optional 45-day or 6-day certificates are not affected. The organization expects the last 90-day certificate to expire on May 11, 2027, and will not revok…
Silent Ransom Group allegedly extorted $207 million from 27 law firms in six months using phone calls and social engineering, not encryption. Silent Ransom Group doesn’t rely on encryption. No malware payload, no locked files, just phone calls and social engineering aimed almost entirely at law firms, and apparently it works extraordinarily well. A new […]
