Phishing - The Top Attack Vector

KnowBe4, a firm started by former hacker and author Kevin Mitnick (RIP), has a blog on phishing emails. It is single-handedly the most severe threat vector in the world.

 
I think we see a good phishing email that gets spread through our organization, perhaps every few weeks. Lately, I think, with a few exceptions, our students and staff are getting better at identifying and flagging them in Exchange, while I end up going into the MS Defender console and extracting them from the system. But as you can see, even on a light day, phish messages can get through, despite best efforts.

BTW - if you're not sure how to do this in Microsoft Defender, I would encourage you to learn how to use the Explorer blade of the Defender console and how to do an extraction, particularly if something gets delivered to thousands of mailboxes and you need to rip it out.

This is gold!!! This could be a TTT session all by itself!!!
My only involvement with Microsoft Defender is to enable it. Once that's done,
I'm moving on down the road to something else.

Thank you Mr. Butler for this fantastic nugget!!!!

Defender P2 is a great platform for total malware management. Only thing above that is XDR which adds in the SIEM and SOAR. Too much for our school, but good for bigger environments.

I briefly worked for a SIEM company. Comprehensive solutions such as XDR, SIEM, SOAR, etc. will be more commonplace if they can get the licensing costs down. Either that, or big orgs will go full Zero Trust Architecture with microsegmentation.
 
72% of successful breaches involve phishing emails,
such as the attack on a public transportation authority
that compromised scheduling systems, and caused
significant delays.

Be diligent all!!!
Phishing emails are out here ruining more than just inboxes—now they're messing with our schedules too! Stay sharp, everyone!

You are the cyber janitor, clearing out the phishing mess before it gets out of control! Thanks for the tip on the Explorer blade—I'll be sure to sharpen my Defender skills!

As far as the bad guys are concerned, you're just another minnow in the pond my friend. There's no discrimination with those guys! Of course, you already know this!!!!
Yes, that's true! Even though I'm a minnow in their phishing pond, I prefer to think of myself as the one that always manages to get away with it by ignoring 😅!
