Agentic AI: The Weapon That No Longer Needs a Warrior
Every weapon begins as an extension of the hand that holds it. The spear lengthened the reach of the arm. The bow sent the point flying without the throw. The rifle placed a man’s death a quarter mile beyond his sight, and the aircraft carried that death across oceans. At each turn, the distance between […]

Stop Your Legacy Infrastructure from Hijacking Your AI Agents
Earlier this month, I spoke at the Gartner Security & Risk Management Summit about a blind spot most security programs are still not accounting for – how attackers are circumventing AI security programs by using legacy infrastructure to hijack AI agents. AI adoption is moving faster than security programs can account for. Roughly 71% of […]
⚡ Weekly Recap: Browser Bugs, EDR Killers, TV Botnet, OpenBSD Flaw, Android Trojan, and More
It’s Monday again. This week’s threat list looks painfully familiar: abused integrations, fake tools, poisoned websites, ransomware crews trying to shut down security tools, and mobile malware asking for way too much control. The annoying part is how little of this feels new. Weak credentials, sketchy downloads, browser extensions with too much access, and WordPress […]

AryStinger Malware Infects 4,300 Legacy Routers to Build Reconnaissance Proxy Network
A new malware family is turning forgotten home routers into a distributed reconnaissance and proxy network, not the DDoS botnet these devices usually end up in. QiAnXin’s XLab calls it AryStinger and counts at least 4,300 infected routers, a total it says is still rising. The distinction matters. AryStinger exists for the stage of an attack that […]

From Assistive to Agentic: The AI Shift That's Redefining Threat Management
Introduction The average enterprise security team has 40 or more security tools, giving a lot of visibility into internal telemetry and asset data. But often, these tools are working in siloes, generating (overlapping) alerts and data. And yet, breach dwell times remain stubbornly long (~43 days), response windows keep closing before teams can act, and […]
Forget Data Leakage: Shadow AI's Real Threat Is Access Control
The first wave of enterprise AI concern was straightforward. It was simply employees pasting sensitive data into public AI tools. Security teams responded with usage policies, domain blocks, and data loss prevention rules. That response made sense at the time. It doesn’t fit the problem anymore. Shadow AI has shifted from a data leakage concern […]

ThreatsDay Bulletin: Claude Chat Abuse, NastyC2 npm Packages, Device-Code Phishing + 25 More Stories
The internet did not break this week. It got used exactly as designed, which is worse. Searches were siphoned through shady browser add-ons.

Adversarial Exposure Validation Turns Security Visibility into Confident Prioritization
For security teams, the findings never stop, but confidence in knowing which ones matter is becoming harder to maintain. The problem is no longer visibility. It’s validation. Security teams must decide which findings warrant action while operating under constant pressure and incomplete information. Increasingly, the challenge is not discovering potential risks. It is determining which […]
The Top 10 Attack Surface Exposures in 2026
Breaches don’t always start with a zero-day. An exposed admin panel can get brute-forced, or credentials reused from a previous attack. But when a vulnerability does drop — like MongoBleed earlier this year, which let attackers pull credentials and session tokens from server memory without authentication — anything internet-facing is immediately at risk. With time-to-exploit […]

Rethinking MDR as Attackers and Defenders Embrace AI
For most of the past decade, managed detection and response was the answer to a real problem. Security teams couldn’t staff around the clock, couldn’t hire enough analysts, and needed someone else to handle the alert queue. MDR stepped in. It worked well enough. Until now. The threat landscape has changed faster than the MDR […]

ThreatsDay Bulletin: Worm Code Leaked, AI Agent Phished, Claude Code Patch + 28 New Stories
It’s been one of those weeks. You expect the usual noise: recycled malware, sloppy attacks, another easy target getting hit. Instead, there’s a supply chain attack kit in a public repo, a $5,000-a-month RAT that clones browsers, and research showing AI agents can be tricked into leaking real credentials. The bigger problem is how polished […]
AI Broke Vulnerability Management. That's Why CISOs Are Moving Budget to BAS.
For thirty years, vulnerability management ran on a buffer: the months between when a vulnerability was found and when someone could figure out how to weaponize it. The solution was straightforward enough; triage by severity, schedule the fix, validate, and move on. The buffer was what made that work. Today, that buffer is gone. AI […]

3 SOC Steps that Shut Down Incident Risks Early
Most organizations still picture cyber defense as a fortress problem: build stronger walls, add more guards, buy another detection engine. But modern incidents rarely crash through the front gate. They drift in disguised as routine activity, hide inside legitimate processes, and quietly accumulate risk long before anyone labels them an “incident.” That changes the role […]

Why Agentic AI Is Security's Next Blind Spot
Agentic AI is already running in production environments across many organizations today. It is executing tasks, consuming data, and taking actions — most likely without meaningful involvement from the security team. The industry conversation has largely framed this as a question of policy: allow it, restrict it, or monitor it? However, that framing misses the […]

One report this week basically […]
Your Purple Team Isn't Purple — It's Just Red and Blue in the Same Room
Defending a network at 2 am looks a lot like this: an analyst copy-pasting a hash from a PDF into a SIEM query. A red team script is being rewritten by hand so the blue team can use it. A patch waiting on a change-approval window that’s longer than the exploitation window itself. Nobody in […]
