Mathematics in Cryptography, Cybersecurity, and Blockchain Technology Summary This paper surveys the mathematical foundations underpinning modern cryptography, cybersecurity, and blockchain systems, outlining how algebra, number theory, probability, and complexity inform encryption schemes, consensus, and security guarantees. It connects core concepts to practical concerns like secure communications, decentralized trust, and resilience, offering guidance for practitioners and students. Why This Matters Addresses pressing domains—cryptography, cybersecurity, and blockchain—by clarifying mathematical underpinnings with potential to inform secure protocol design, formal verification, and post-quantum transitions. Cross-disciplinary reach is strong. However, as an overview rather than introducing new algorithms or proofs, its direct research novelty seems limited, suggesting medium long-term impact.

Artificial intelligence notwithstanding, the vast majority of CISOs in northern Europe say they're facing no more serious cyberattacks than they did two years ago.

Palo Alto Networks has warned that a recently disclosed medium-severity security flaw impacting PAN-OS and Prisma Access has come under active exploitation in the wild. The vulnerability, tracked as CVE-2026-0257 (CVSS score: 7.8), refers to a case of authentication bypass that could be exploited by bad actors to set up VPN connections. "Authentication bypass vulnerabilities in the

A purported leak exposing 5.8 million records of Uruguayan citizens is the latest incident where cybercriminals targeted government agencies to monetize citizen data.

Threat actors are continuing to exploit a critical, now-patched security flaw impacting FortiClient Endpoint Management Server (EMS) deployments to deliver a credential-stealing malware family dubbed EKZ Infostealer. "The campaign abused trusted endpoint management infrastructure to deliver malware across managed endpoints," Arctic Wolf said. "Threat actors disguised the credential stealer

A critical security vulnerability has been disclosed in Gogs, a popular open-source self-hosted Git service, that allows an authenticated user to execute arbitrary code under certain conditions. The security flaw, per Rapid7, is rated 9.4 on the CVSS scoring system. It does not have a CVE identifier. "The vulnerability allows any authenticated user to achieve remote code execution (RCE) on

Microsoft has rolled out updates to fix a remote code execution vulnerability impacting SharePoint that could be exploited by bad actors in attacks without requiring any specialized conditions to be met. The vulnerability, tracked as CVE-2026-45659, carries a CVSS score of 8.8. It has been assigned an important severity. "Deserialization of untrusted data in Microsoft Office SharePoint allows
