📣I’m happy to announce that I’m planning to write a brand new “macOS Vulnerability Research” training. 🥳 Considering the amount of work the writing requires it will be available late 2025 or early 2026. It will be Live class only, and likely only once or twice a year.

Hamas killed 1,200 innocent people on Oct. 7. Yet the world blames Israel. How does that make sense? Larry Elder explains why Israel’s survival is about more than borders—it’s about civilization itself. Watch the Full Video now.

Let me blow your mind real quick: When you use Remote Desktop (RDP), Windows secretly takes screenshots of what you are doing. It’s called the RDP Bitmap Cache. To make the connection faster, Windows saves small tiles (images) of the remote screen to your hard drive in a bin

4/4 I could agree that SSIDs are not unique enough, but BSSIDs are unique and you can even use Apple's own service to lookup location. So while Apple does try to protect this data, they are not willing to pay a single cent, although it clearly falls in scope based on their site

3/n Apple fixed almost all of my reports (some are underway). How much they paid out as bounty? 0$ !!! Yes, 0$ Why? Because you need to use an extra step, a lookup to get the precise location.

2/n Before the recent change it was specifically advertised that such data falls in-scope. It's protected, and you can also use this to locate the user.

🧵 1/n... another reason I start losing complete faith in Apple's Security Bounty program. Not that long ago I submitted 32!! tickets where I found SSID and BSSID leaks through various sources. Why is it a thing? Because: 1. Apple started to protect this info with TCC 2. Because

We found that the macOS infostealer AMOS was using a ChatGPT lure to get users to install it 😔 I know you are tired of stealers, so we didn't cover it too much on its own. But the lure itself is interesting. https://t.co/KmWCUQdaO3

Here's my slightly longer talk from earlier this year at @bsidesbud: give this a watch if you are interested in the Apple bug bounty. Unfortunately with the latest changes TCC bypasses are worthless now, but the rest of the talk is still pretty useful https://t.co/fo9wfggbht

I've been seeing a lot of discussion online recently about the changes to Apple's bug bounty program, specifically the downgrading of payouts for TCC bypass vulnerabilities. I was recently asked for my thoughts on this matter. I figured the best way to illustrate the importance
