Patch your shit today, bro.

Fine. Since you asked twice:

• On the KEV list and internet-facing: today. Hours to days, not weeks. VPNs, firewalls, and file-transfer apps go first, because that's where attackers go first.
• On the KEV list, internal: within days, and always before the CISA due date. "Internal" is a network location, not a force field.
• Critical or high, not (yet) exploited: within your normal cycle, ideally inside 2–4 weeks. That "(yet)" is doing a lot of work.
• Everything else: monthly. Microsoft's Patch Tuesday (second Tuesday of the month) is a fine heartbeat. It's literally on a calendar. You have a calendar.
• Browsers and endpoints: turn on auto-update, then actually check it's applying. "I clicked 'remind me tomorrow'" 47 times is not auto-update.

"Once a quarter" isn't a cadence, it's a hope.

The Known Exploited Vulnerabilities catalog: CISA's list of bugs that someone is already using to break into things. Not theoretical, not "could potentially," not a conference talk. Actual crimes.

Every entry has a CVE, what to do about it, and a due date. It's the best free "patch this first" list on the internet, and the government made it for you. When was the last time that happened?

They're deadlines for US federal civilian agencies under CISA's binding operational directive. You're not legally bound by them. Congrats on the loophole.

Unfortunately, ransomware crews don't check whether you're a federal agency before they encrypt you. Treat the date as a ceiling, not a target. Under BOD 26-04 the feds get as little as three days. You don't get "eventually."

Countdowns on this site run to the end of the due date in UTC, because time zones are also a vulnerability.

Because the catalog goes back to 2021, and deadlines on old entries came and went while everyone was "prioritizing."

Overdue doesn't mean dead. Years-old KEV bugs still get exploited constantly, because years-old unpatched boxes are still out there, humming along, waiting for their moment. Is one of them yours? Check My stack. Want only the live deadlines? Use the "Still ticking" filter and pretend the rest don't exist (they do).

CVSS tells you how bad a bug could be. KEV tells you someone is actually doing it. One is a weather forecast, the other is water coming under the door.

Start with exploitation evidence, then ask whether the attack can reach the vulnerable code and what compromise would actually damage. A medium-severity KEV can deserve attention before a 9.8, but your deployment and the potential consequences matter. Sorting a spreadsheet by CVSS and starting at the top is not a strategy, it's a screensaver.

Working in FedRAMP? Patch your shit. For FedRAMP. connects the impact, reachability, and remediation questions to a method you can explain and audit.

Then you earn that security budget. "We're waiting on the vendor" is going to look fantastic in the incident report.

• Read the fucking advisory. Disable the vulnerable feature. Set the vendor-documented environment flag. Restart or redeploy if required, then verify it took effect. Wishful thinking isn't a configuration setting.
• Make your WAF earn its invoice. Add a rule for the exploit, put it in blocking mode, and test it. The attack has to actually pass through the WAF. That lovely rule on a completely different traffic path is home decor.
• Stop showing your ports to strangers. Get the affected service off the internet, lock down management interfaces, and restrict access. "Nobody knows that URL" is a hell of a security architecture.
• Check that your EDR does more than bill you. Update it, confirm a matching signature or behavior detection is enabled on the affected hosts, and verify prevention is active if you're counting on it to block the exploit. A green dashboard isn't a force field.
• Check whether you've already had visitors. Hunt for compromise using the vendor's indicators and your logs. If it's on KEV, someone may already be in. They won't send a calendar invite.
• If the potential damage is bad enough, turn that shit off. Disable the service or take the system offline until you can patch or verify an effective mitigation. You can explain a deliberate outage. Explaining six terabytes on a leak site takes more slides.
• Retire the museum exhibit. If it's end-of-life, replace it. "But it still works" is also true of the exploit.

The vendor is writing a patch. You have shit to do.

Then you'll have a bad afternoon. Ransomware is a bad quarter, a press release, and a very awkward board meeting.

Snapshot or back up first, test on a small pilot group, then roll out wide. Keep a rollback plan. And if the patch genuinely breaks prod, tell the vendor loudly, apply mitigations, and try again. "It might break" is a reason to test, not a reason to wait until 2031.

Look at you! Almost.

• Verify it landed. Check the version. "The ticket says done" is not a version number.
• Reboot if it needs one. A kernel patch you haven't booted into is a decorative patch.
• Look for compromise. Patching locks the door. It doesn't evict whoever walked in last Tuesday.
• Rotate credentials if the bug could have leaked them.

Then you're done. Until tomorrow. See you tomorrow.

Every hour, a robot pulls CISA's official KEV feed plus a pile of vendor advisories and security news, and caches it. The robot doesn't sleep, take PTO, or wait for a change advisory board. Be like the robot.

Every CVE links to NVD and CISA. Check our homework before you act on it. We'd check ours, if we were you.

YOU ACTUALLY BELIEVE PPL WHEN THEY SAY DON'T? LLLOLLLLLLL.

But seriously, I honestly don't care that much to track you.

Are you seriously going to argue against this????? WTF bro.

Because "please consider applying security updates at your earliest convenience" has been tried for 25 years. Look around. How's that going?
