CISA's Urgent Ivanti Warning: 105 Exploit Attempts in the Wild

Michael Miller · 2026-10-14

Tuesday started like any other day for a lot of IT teams. Then CISA dropped a warning that made plenty of coffee go cold. The U.S. Cybersecurity and Infrastructure Security Agency is telling organizations to patch their Ivanti Connect Secure (ICS) appliances right now. Not next week. Not after the next change window. Now. Here's why the urgency is real: honeypots have already logged 105 exploit attempts against this thing. That's not a drill, and it's not theoretical. Attackers are actively poking at the door. ### What Exactly Is the Problem? The flaw is tracked as CVE-2026-104935, and it carries a CVSS score of 8.6. In plain English, that's serious. This is an authentication bypass, which means an attacker can slip past the login process without valid credentials. Once inside, they can potentially move deeper into your network. If you're running Ivanti Connect Secure, you're the target. It doesn't matter if you're a small shop in Ohio or a Fortune 500 in New York. If the appliance is exposed, it's fair game. ### Why 105 Attempts Should Get Your Attention Honeypots are basically decoy systems set up to look juicy to attackers. When 105 attempts show up against them, that tells us the exploit is already circulating in the wild. Someone has figured it out, and they're not keeping it to themselves. Think of it like this: your front door has a lock that a bunch of people already know how to pick. You wouldn't wait for a break-in to fix it. You'd fix the lock today. ### What You Should Do Right Now - Update Ivanti Connect Secure to the latest version immediately - Check your logs for any signs of unusual authentication activity - Rotate credentials for any accounts tied to the appliance - Review your network segmentation so a single compromised device can't roam freely - Subscribe to CISA alerts if you haven't already If you're not sure whether you've been hit, don't guess. Bring in someone who can do a proper forensic review. A quiet compromise is worse than a loud one. ### A Quick Reality Check on Patching I get it. Patching is annoying. It means downtime, testing, and someone giving up their weekend. But compare that to the cost of a breach. The average incident response bill can run into the hundreds of thousands of dollars, and that's before you count the reputational damage. > "The only patch that matters is the one you actually deploy." — every security engineer, ever. That quote isn't fancy, but it's true. A vulnerability you know about and ignore is a choice. CISA is handing you the playbook. The only question is whether you'll use it. ### The Bigger Picture This isn't just about Ivanti. It's a reminder that edge devices are the new front line. VPNs, firewalls, and remote access appliances are constantly under fire because they sit right at the boundary between the internet and your internal network. If you're in the antidetect browser space, you already know how much attention these edge systems get. Attackers love them because one successful bypass can open up everything behind them. So take CISA seriously. Patch today. Check your logs. And if something looks off, assume it is and dig in. Your future self will thank you.
