SANS Institute Launches AI Cybersecurity Hackathon

The crime solver wore disguises, spied on targets, and built intelligence networks long before modern-day tactics emerged. He has lessons for today’s ethical- and nonethical-hat hackers.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added a critical security flaw impacting Citrix NetScaler ADC and Gateway to its Known Exploited Vulnerabilities (KEV) catalog, officially confirming the vulnerability has been weaponized in the wild. The shortcoming in question is CVE-2025-5777 (CVSS score: 9.3), an instance of insufficient input validation that

The threat actor known as ToddyCat has been attributed to a new malware called Umbrij that’s designed to gain surreptitious access to a victim’s email correspondence via the Google API. “In this campaign, the attackers focused their attention on corporate email communications hosted on Gmail, targeting access compromise via APIs,” Kaspersky said in a detailed…

Barracuda has disclosed details of two vulnerabilities affecting its products that, if chained together, could allow an attacker to bypass authorization controls and gain root access to a susceptible device. The vulnerabilities, a pre-authentication authorization bypass vulnerability and a command injection vulnerability, have been assigned the CVE identifiers CVE-2026-116606 (CVSS score: 9.3)

A four-question exercise that CISOs can use to create a threat model that promises results, without a big spend.

The threat actors are exploiting non-interactive sign-ins, an authentication feature that security teams don’t typically monitor.
