Cyber Threat Intelligence

Organizations are facing an intensifying and multi-vector threat environment, with attackers actively exploiting critical vulnerabilities across widely deployed platforms including Rejetto HFS, Citrix NetScaler, and Realtek-based devices, while the rapid expansion of credential surfaces and AI-driven data access points continues to outpace security team visibility and controls. In response, industry leaders like Apple are proactively tightening access governance frameworks, underscoring the urgent need for enterprises to accelerate vulnerability patching cadences, strengthen identity and credential management programs, and ensure security strategies keep pace with the evolving AI and connected-device landscape.

The Credential Layer Is Expanding Faster Than Security Teams Can See It

Every modern enterprise depends on credentials. This is how humans, systems, and now AI, all connect to data, services, and each other securely. GitGuardian helps secure that credential layer through three connected capabilities: Detect, Remediate, and Prevent. The journey starts with detection, because organizations first need to understand what c...

Realtek Jungle SDK Exploit Attempts Deliver Cling Botnet With STUN-Based C2

Threat actors have been observed attempting to exploit a now-patched critical security flaw impacting the Realtek Jungle software development kit (SDK) to deploy a botnet malware called Cling. "Cling is notable not because it introduces a new propagation technique, but because it repurposes ordinary STUN behavior into a practical command-and-contro...

Apple Plans Tighter macOS Full Disk Access Controls Over AI Agent Data Access

Apple has announced that it's taking steps to tighten controls around a macOS setting called Full Disk Access (FDA) due to security risks posed by artificial intelligence (AI) agents. "Some developers are using Full Disk Access in ways that could put users at risk, exposing everything on their systems—including files, mail, messages, and even brows...

SMB SPOTLIGHT

Small Business Spotlight

Small businesses are increasingly finding themselves in the crosshairs of sophisticated cyber threats, from actively exploited vulnerabilities in widely used networking tools like Citrix NetScaler to the growing complexity of agentic AI security and adversary simulation tactics. This week's spotlight breaks down what these developments mean for SMBs and how you can take practical steps to stay ahead of attackers.

From the CTO's Desk
Daniel Ramos  — CTO — Intelligent Automation  LinkedIn

Welcome back, fellow travelers on the information superhighway — where the potholes are zero-days and the speed cameras are all compromised. Buckle up.

First, credentials: they're multiplying faster than tribbles on a starship. Your security team literally cannot see every identity surface anymore — service accounts, AI agents, OAuth tokens — it's a credential buffet and attackers have a VIP pass. Audit your non-human identities this week. Yes, this week. I'll wait.

Speaking of uninvited guests, the Realtek Jungle SDK exploit is back delivering the "Cling" botnet — because apparently malware authors are now naming things after bad habits. It uses STUN-based C2 to blend into normal traffic. Patch your embedded devices or accept that your router has joined a gang.

Apple is tightening macOS Full Disk Access controls around AI agents, which is honestly the responsible move given that your AI assistant probably doesn't need to read your therapy notes. Good on them.

Rejetto HFS users — there's an active flaw enabling admin session forgery and RCE. If you're still running HFS in 2026, that's a conversation we need to have. Patch or retire it, no debate.

Finally, a NetScaler zero-day is kneecapping SAML deployments. If your authentication infrastructure just vanished, now you know why. Apply Citrix mitigations immediately and monitor SAML assertion logs like your job depends on it — because it does.
