Since last year, I thought Ivanti Endpoint Manager was the most insecure tool you could use.

This year, I know it’s been Elon all along.

Excellent research by Sagi Olshansky shows how even a simple "Terms of Service" conditional access option in Entra ID can become a thorn in the side of phishing threat actors.

I've been dealing with mysterious high CPU utilization from WmiPrvSE.exe for MONTHS. I finally did some digging using github.com/luctalpe/WMI... (run wmimon from an elevated cmd prompt). Guess what the culprit was?

I'm currently doing super exciting research (that's a joke 😭) trying to decide which invoicing platform with API access to use.

Can anyone confirm if Zoho Books is a good platform or if there is any alternative worth considering?

I'm having the time of my life 😆

I keep catching myself referring to "Linkin Park" as "LinkedIn Park".

Is it a sign of growing old? 👴

Evilginx Pro Update:

Tool is ready and awaits release.

I'm now creating an online shop engine, because why not 😜

I hope one day it becomes Steam for cybersecurity tools with Evilginx Pro its first release, like Half-Life 2 on Steam exactly 20 years ago.

Red team tools unite!

Defenders use cross-origin requests through CSS url() or injected JS to leak your phishing URL in the HTTP Referer header.

Today, I've been reminded about the excellent post by Keanu Nys, which contains a lot of great evasion ideas!

Does anyone else feel Bluesky has finally solved the notification stacking/clutter problem Twitter has been unable to solve since its beginning?
November 15, 2024 at 12:05 PM
I'm reaching the point where most of the Twitter accounts I followed for news, have migrated to Bluesky.

Soon I may have no reason to go there anymore! 🥳
