    fix interesting bug in my transmitter: phase discontinuity in the FSK modulation.Previously, generate_tone() restarted the sine from phase 0 for every bit.At the boundary of each of the frame's ~160 symbols the signal jumped - an audible click and spectral smearing, which raises the error floor on a real speaker --> microphone path.Real Bell 202/FSK is continuous-phase FSK. The generator's phase now accumulates continuously across all symbols (build_signal carries a phase accumulator).Also fully rewrote the transmitter's terminal output#hacking #research #malware #stealer #linux #fsk #fft #dft #math #physics #signal #programming

    Can't even showcase actual dope labs because of these stupid compliance/ethics restrictions! Ethical guardrails are killing me, I can't drop real-world PoCs for readers. My brain is totally melted 😈😈😈 #research #malwaredevelopment #hacking #book

    Writing a book with a publisher is a complete nightmare. I really don't like being rushed, and I try to explain to them that I need to finish and double-check all the practical examples; I can't provide material that I haven't personally verified. I'm amazed by people who work, teach, and also write books at the same time. 😂😂😂 #hacking #malware #research #book

    The second edition of the book is already in the finishing line. But the first part will most likely come out first, as I won't be able to finish all the practical examples in time. I'm trying to improve the quality of the material. #malware #hacking #research #redteam #blueteam #book

    VirusTotal banned me, and I think I know why. I tried to parse a bunch of signatures and kept exceeding my request quota. And it won't let me generate a new key before banned. What kind of stupidity is this? 😈 #hacking #threatintel #malware #research #cybersecurity #programming
