Fixing my Virtual Machine after breaking it has to be one of the most exhausting things ever.
Cybersecurity and Troubleshooting🤝

[Rosemary @RMJSec]

Same as Troubleshooting in Cybersecurity

Debugging isn’t a skill.
It’s a superpower you earn by breaking things over and over.

The worst part about being alone is that sometimes
You’ll have to handle the failures alone as well

It is well

I'm learning gratitude even when things are not going well.

FYI: Your life will get a whole lot better if you're grateful

I'm building cybersecurity skills and incorporating with AI.
I'm trying to figure out how AI can be used to make cybersecurity easier and reduce burnouts.

[Kevin Szabo @KevinSzabo14]

What are you building?

I want to know what everyone is up too?

Introduce yourself?

A part of cybersecurity no one talks about:
The Troubleshooting!!!
I have built personal labs, hacked and defended my windows and windows server using MITRE ATT&CK and custom exploits.
Yet, the Troubleshooting makes me feel like I'm not doing enough or I haven't learned enough.

7. The USB Killer

Hack Name: USB Kill Attack
How?: A tiny USB stick with capacitors charges from the USB port, then discharges 200+ volts into the device frying it instantly. Used for destruction, not data theft.

⚡ Some devices catch fire. Never plug in found USBs.

Here are 7 weird cyber hacks that actually worked. These are surprising, creative, and sometimes straight out of a movie, but all real:

🧵

1. Laser Beams to "Hear" What You Say (via Light Bulbs)

Hack Name: Lamphone Attack
How?: Attackers pointed a telescope with a laser at a hanging light bulb in a room. Tiny vibrations on the bulb, from people speaking, let attackers reconstruct conversations in real time.

[Rosemary @RMJSec]

6. Radio Waves to Steal Air-Gapped Data

Name: AirHopper
How?: Even if a computer is not connected to the internet (air-gapped), attackers used electromagnetic signals emitted by the video cable to transmit stolen data which was received by a nearby mobile phone’s FM radio chip.

[Rosemary @RMJSec]

5. Fax Machine Takeover
Hack Name: Faxploit
How?: Attackers sent a specially crafted fax to an HP all-in-one printer. That single fax triggered a buffer overflow, which allowed remote code execution and access to the entire internal network.

Lesson: Don’t underestimate old tech.

[Rosemary @RMJSec]

4. Balloon Ride to Hack Tesla

Hack Name: Drone Injection via Wi-Fi
How?: Researchers used a drone hovering near a Tesla (Model X) to deliver malicious payloads over Wi-Fi (no physical access). The hack exploited a Bluetooth vulnerability to gain full control of the car.

[Rosemary @RMJSec]

3. Keyboard Sounds → Password Theft
Hack Name: Acoustic Side Channel Attack
How?: By recording the sounds of someone typing, researchers trained machine learning models to guess what keys were being pressed with up to 90% accuracy.

🎧 Just a mic next to your keyboard is enough.

2. Hacking via a Smart Fish Tank
Hack Name: Aquarium Breach
How?: A casino installed a smart fish tank with internet-connected temperature controls. Attackers breached the fish tank, then used it as a pivot point to access the casino’s internal network and steal high-roller data.
