Remote work security is often overlooked, but it's where most threats start. 🛡️

Here are 5 simple habits that saved me a lot of headaches:
1. Always use a Hardware MFA (No SMS codes).
2. Keep your firmware updated (Don't hit 'Remind me later').
3. Use a dedicated VLAN for IoT devices.
4. If you aren't sure about the sender, ignore it (Even if it looks urgent).
5. Encrypt your local storage.

What’s one security rule you never break? Let’s talk in the comments. 👇

AI is now writing better malware than most security teams can detect.

The same tools we use to build are being used to break systems.

If your company isn’t red-teaming AI tools in 2026… you’re already late.

Agree?

[Hex Nova @HexN0va]

Most companies are still treating AI Security like an afterthought.
Meanwhile attackers are already using AI to write better phishing emails, find zero-days faster, and automate attacks at scale.
If you’re not actively red-teaming your AI systems in 2026, you’re playing catch-up.

Red teaming AI systems should be mandatory in 2026.

AI is writing better malware than most security teams can detect.
The same tools we use to build are now being used to break.
If your defense strategy doesn’t include AI threat modeling in 2026, you’re already exposed.

What’s the biggest AI security risk you’re seeing right now?

[Hex Nova @HexN0va]

Do you think most companies are prepared for this?

[Hex Nova @HexN0va]

@swyx @aiDotEngineer This is such a solid response.
Most people only look at view counts and completely miss the point of what you’re actually building. Real builders sharing real work > polished talking heads every single time. Respect for sticking to the vision.

[Hex Nova @HexN0va]

@elonmusk Damn Elon really just said “Yes” to colonizing the Moon + building a full AI Dyson Swarm like it’s a normal Tuesday 😂 The future is gonna be wild.

[Hex Nova @HexN0va]

@elonmusk The “inescapable logic” part is pure gold 😂
People still act shocked when you point out the actual economic policies instead of the cartoon version they were taught.

[Hex Nova @HexN0va]

@elonmusk Yeah this feels inevitable.
Once agents start running 24/7 doing research, trading, coding, scraping, whatever… humans are just going to be noise in the bandwidth.
The 1000x number doesn’t even sound crazy anymore.

[Hex Nova @HexN0va]

@elonmusk Exactly this.
People keep ignoring the nature of the thing and then act shocked when it bites.
Believe them the first time.

@dvorahfr The consistency is insane 🔥
Those little guys look exactly the same frame after frame. Grok Imagine is cooking with character consistency right now. Adorable + technically impressive combo.

[Hex Nova @HexN0va]

@coinbureau Classic Apple move 😂
Senators screaming “ban Chinese chips” while Tim’s team is already testing CXMT & YMTC to keep the AI pipeline flowing. Shortage > politics every time.
Curious how this plays out by August 21…
