You need a layered defense. Here’s our vetted stack for this specific threat.

Kaspersky EDR
This is your *sensor*. It’s the #1 tool for providing the behavioral telemetry (process chains, network data) that your *human* MDR team needs to hunt.Edureka — Threat Hunting Training
Your SOC team must become Hunters. Train them *now* on AI-Phishing Defense, PowerShell Threat Hunting, and MDR TTPs.TurboVPN
The “Vibe Hack” (phish) often lands on a *remote* device on *public Wi-Fi*. A VPN encrypts this initial access channel.

Alibaba Cloud (Private AI)
The *real* solution. Host your *own* private, secure LLM on isolated cloud infra. Stop leaking data to public AI.AliExpress (Hardware Keys)
*Mandate* this for all C-Suite and Finance. A FIDO2/YubiKey *kills* the credential phish.Rewardful
Run a bug bounty program. Pay white-hats to find flaws *before* APTs do.

We are the “AI + Human” model. We are the expert team you call when a CISA KEV alert drops. We stop the breach and prove you are secure.

• Emergency Incident Response (IR): Our 24/7 team will deploy *today* to hunt for the post-exploit TTPs from CVE-2025-6554.
• Managed Detection & Response (MDR): Our 24/7 SOC team becomes your “human sensor,” watching your EDR logs for the behavioral signs of this attack.
• Adversary Simulation (Red Team): We will simulate this *exact* V8-to-`SYSTEM` kill chain to test if your EDR and your team can actually detect and stop it.
• PhishRadar AI — Our app to detect and block the initial spear-phishing email that delivers the zero-day link.
• SessionShield — Protects your SaaS apps *after* the breach, when the attacker steals the browser cookies.

FAQ

Q: I use Microsoft Edge / Brave / Opera. Am I safe from this Chrome flaw?
A: NO. This is a vulnerability in Chromium V8, the engine that *all* these browsers use. You are just as vulnerable. You MUST go to `Help > About` and force the update on *all* your Chromium-based browsers.

Q: I use Firefox. Am I safe?
A: From *this specific* CVE, yes. Firefox uses its own engine (SpiderMonkey). However, you are still vulnerable to the *class* of attack (phishing) and the *post-exploitation* TTPs (cookie theft). Your defense strategy should be the same.

Q: I forced the update. Am I 100% safe?
A: You are safe from *new* attacks using this flaw. You are *not* safe if an attacker *already* breached you *before* you patched. This is why “Patch” is only Step 1. “Hunt” (Step 2) is *mandatory*. You must call our IR team or your MDR provider to hunt for compromise.

Q: How do I hunt for this?
A: You need a behavioral EDR (like Kaspersky) and an expert MDR team. The hunt query is: “Show me anomalous process chains” (e.g., `chrome.exe -> powershell.exe`) and “Show me all EDR agent service-stop events.”
