Janus: Compiler-Based Defense against Transient Execution Attacks Using ARM Hardware Primitives

We present Janus, a compiler-based security framework that mitigates transient execution attacks like Spectre and control-flow hijacking on ARM64 platforms. Janus integrates speculative execution and control flow dependencies with PA modifiers, using PA and BTI microarchitectural features to...

Secure Development of a Hooking-Based Deception Framework against Keylogging Techniques

Keyloggers remain a serious threat in modern cybersecurity, silently capturing user keystrokes to steal credentials and sensitive information. Traditional defenses focus mainly on detection and removal, which can halt malicious activity but do little to engage or mislead adversaries. In this pape...

Quantum Enhanced Entropy Pool for Cryptographic Applications and Proofs

This paper investigates the integration of quantum randomness into Verifiable Random Functions VRFs using the Ed25519 elliptic curve to strengthen cryptographic security. By replacing traditional pseudorandom number generators with quantum entropy sources, we assess the impact on key security and...

NanoZone: Scalable, Efficient, and Secure Memory Protection for Arm CCA

Arm Confidential Computing Architecture CCA currently isolates at the granularity of an entire Confidential Virtual Machine CVM, leaving intra-VM bugs such as Heartbleed unmitigated. The state-of-the-art narrows this to the process level, yet still cannot stop attacks that pivot within the same...

The Evolution of Zero Trust Architecture (ZTA) from Concept to Implementation

Zero Trust Architecture ZTA is one of the paradigm changes in cybersecurity, from the traditional perimeter-based model to perimeterless. This article studies the core concepts of ZTA, its beginning, a few use cases and future trends. Emphasising the always verify and least privilege access, some...

CVE-2024-35843

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Use device rbtree in iopf reporting path The existing I/O page fault handler currently locates the PCI device by calling pcigetdomainbusandslot. This function searches the list of all PCI devices until the desired...

CVE-2024-26759

The CVE-2024-26759 issue is a Linux kernel race in swap caching. Two threads swapping the same entry with SWP_SYNCHRONOUS_IO can end up installing different pages (A and B), causing ABA and possible data corruption when the entry is freed and reused. The fix uses swapcache_prepare to pin the swap...

Microsoft SQL Server db_ddladmin Privilege Escalation Vulnerability

Microsoft SQL Server versions 2014 through 2022 suffers from a dbddladmin privilege escalation vulnerability. When escalated to Microsoft as a concern, they instead opted to update their documentation to note that this is possible instead of addressing the issue. Title: SQL Server Privilege...

Security Oriented Fuzzer: American Fuzzy Lop

American fuzzy lop is a security-oriented fuzzer that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary. This substantially improves the functional coverage fo...
