RevStealer is an infostealer first observed in September 2026 that targets Windows systems, with reported 64-bit execution and JavaScript-based components. It is built to steal authentication credentials and other sensitive user data while emphasizing stealth through anti-debugging, anti-sandbox, anti-VM, and evasion features. Its threat significance comes from a short, theft-focused execution model that pairs broad data collection with concealed command-and-control and exfiltration behavior.

Any SCA tool worth its salt has reachability analysis these days. When a dependency has a known vulnerability, these tools can tell you whether your code calls the affected function. This is pretty much non-negotiable because it helps teams focus their security efforts instead of sifting through noise. Every other step in prioritizing dependency CVEs builds on it. But just because the vulnerable function is reachable doesn’t mean it’s exploitable.

AI guardrails are sold as a solution to keep models behaving as intended - but it can be hard to figure out what you’re getting. The problem starts with the word itself. "Guardrails" means different things depending on who's selling them. Some vendors use it for simple prompt filtering, others bundle in entirely different controls and call it "guardrails" because the word sounds reassuring. Without a shared definition, buyers can't easily tell what they're actually getting.

For years, we described phishing as an email problem: an attacker writes a convincing message, sends it to thousands of people and waits for someone to click. That model is now outdated. Microsoft’s disruption of YAM Store, CoGUI and Iron Man exposed something much larger: a cloud-based impersonation industry.

AI tools can scan an entire application in minutes. They flag known vulnerabilities, map attack surfaces, and generate reports that look thorough. So, it’s fair to ask whether human penetration testers are still necessary. They are.
