Open Source Security Tools: A 2026 Guide

A mid-sized SOC can have endpoint telemetry in one platform, cloud logs in another, vulnerability findings in a third, and identity alerts somewhere else entirely. Analysts switch consoles, normalize the same event repeatedly, and still miss the incident that required context from several systems. The problem usually isn't a lack of detection technology. It's the absence of a shared data model, disciplined correlation, and evidence that security and compliance teams can use together.

Why Your AI Application Is Exposed

Imagine getting three separate security reports back for your new enterprise AI assistant: On paper, the application looks ready for production, but in reality, a threat actor bypasses your guardrails in minutes. How? By using the AI model as an intermediary. The attacker steers the LLM to invoke the internal utility tool, thereby bridging an untrusted prompt directly to the backend execution sink.

'The Gentlemen' Profile: Why This Ransomware Group Wants In Before It Locks You Out

The Gentlemen is a financially motivated ransomware group that combines data theft with encryption to increase pressure on victims. They first came onto the threat scene in July 2025. Rather than relying on encryption alone, the group exfiltrates sensitive business data before locking files, leaving organizations to deal with both operational disruption and the risk of stolen information being exposed.

Attackers Use Vishing Attacks to Distribute New Android Malware

Attackers are distributing a new Android malware called “WindRelay” via phone-based social engineering attacks, according to researchers at Group-IB. The attackers call the victims, impersonating bank employees and instruct them to install a malicious app. In one instance observed by Group-IB, the scammers carried out the entire attack in just thirteen minutes.

How to Send a Secure Email with Gmail, Outlook, Yahoo, and More

Sending an email is easy, but sending an email securely with the right settings can be time-consuming or difficult if you’re unsure how to configure the right settings. Even so, securing your emails protects your business from phishing attempts and ransomware. If you use an email for personal use, the same risks of email scams apply, so the techniques you learn in this article will keep your personal and business information secure from hackers.

Nucleus Helix Was Built to Fix Exposure Management's Breaking Point

Let me be direct about something the industry keeps dancing around: the vulnerability problem isn’t getting better. It’s getting structurally worse. The wave of AI-generated code and compression of time to exploit thanks to frontier AI models like Mythos is about to make “worse” look quaint. If your vulnerability and exposure management program is still built around scanner cycles, ticket queues, and CVSS scores, you’re not running a security program.

AI/LLM Penetration Testing in 2026: The Complete Guide

Most organisations now run at least one LLM in production, and a growing number run agents that call tools and act without a human in the loop. The security testing those systems receive was designed for deterministic software. AI applications fail differently. The payload is natural language, the same input can be safe nine times and unsafe on the tenth, and the malicious instruction often arrives inside a document or tool description rather than from the user.

Dark Caracal Reloaded: New Malware, Same Hunting Grounds

Arctic Wolf Labs exposes Dark Caracal’s evolving tradecraft, linking 249 samples to two operational build profiles and a resilient Ethereum-based C2 architecture targeting Latin America. In June 2026, Arctic Wolf Labs investigated a targeted intrusion affecting a communications organization in Venezuela.

How Many Cyber Risk Scenarios Should You Model?

Scenario libraries grow. A program starts with ransomware and a data breach, adds a third-party failure after a supplier incident, splits ransomware into encryption and extortion variants, adds a cloud outage, and two years later holds forty entries nobody has revisited. ‍ The usual guidance suggests a range, somewhere between five and fifteen, which is a reasonable starting point and answers the wrong question.
