Dear $VENDOR, can you please stop pushing your full ecosystem and invest into the integration with other solutions ? Nobody starts with a blank sheet (or wants to rely on a single stack) for their security controls. Thank you !

Almost 10 years ago (sick how fast time flies!), I led my very first open workshop in English at the greatest @brucon Conference. That's where my international training adventure began (for which I am grateful to this day), and it hasn't stopped since. I'm coming back this year - #BruCON 0x12 - with bloody "Practical Linux Attack Paths and DFIR/Hunting for Red and Blue Team v2.0" training in Mechelen, Belgium. 3 days - 21-23 September. 100% hands-on. 100% Linux Purple Teaming for life! If you defend (or attack) Linux, this training has been built for you. Short theory dumps and just search-copy-paste-run blocks of real offensive tradecraft going head-to-head with live detection, hunting, DFIR, and prevention strategies inside the #PurpleLabs Cyber Range. Here is the registration: https://t.co/E00Yv9Tlqa

Interesting, yet not surprising learning about privacy #GDPR. Over the last couple of months, I’ve been getting lots of direct marketing phone calls on my cell phone. This is odd as I tend to keep my cell phone number private and only share it with people I know. (1/5)

With Cyber security news dominated by data breaches (Oracle, Signal-gate), @troyhunt has shown how to properly respond to an event like this. Nobody is infallible, not even seasoned security professionals but the way you respond makes all the difference! https://t.co/GHBAXFWjq7

In all seriousness, we offer our most sincere condolences to our friends and colleagues who work at CrowdStrike.

We're sorry we're memeing so hard — but the situation is so unbelievably bad it's borderline satire.
