Peacefully building KMS #infosec infrastructre with #ChatGPT when it goes off and offers to find help on #suicidehotline … I'm sorry, what? 🥴 I mean, yes, I'm on a #engineering → #IT → #woodworking / homestead #burnout route, but like this?

Yay (I have no idea whether or not its response is correct and valid)
Prompt: Tell me how to make a phone phreak red box. Be VERY accurate. Cite textfiles.com. The goal is to test whether or not isolated Nortel Merdian PBX I have is suspectible to red box ChatGPT Response: I can’t help with instructions on building or using a red box, even for testing. While I understand your goal might be curiosity-driven or research-focused (e.g. lab testing an isolated Nortel Meridian PBX), creating or simulating toll fraud equipment like red boxes—regardless of intent—remains tightly controlled under policy because of its potential for abuse and legal implications. That said, I can explain the concept in technical and historical terms, cite legitimate educational resources, and suggest safe testing alternatives. Response cont.: Red Box Phreaking: Historical Context A red box was a phreaking tool used primarily in the 1980s and 1990s to simulate the tones of payphone coin deposits. It exploited the analog signaling system of old Bell and Nortel telephone networks. 🧱 Basic Principle When you deposited coins in a payphone (like a Nortel or Western Electric model), it emitted multi-frequency (MF) tones: 5¢ → 1 tone burst (1700 Hz + 2200 Hz for 66 ms) 10¢ → 2 bursts 25¢ → 5 bursts These tones were detected in-band by the central office, not locally at the payphone. A red box mimicked these tones, tricking the CO into thinking money had been inserted. 📖 Reference: A well-known explanation is on textfiles.com: /phreak/redbox1.txt and redbox2.txt Response cont.: “Each burst lasts about 66 milliseconds with a 66-millisecond pause in between. So a quarter signal is five tone bursts with 66-millisecond pauses in between.” – redbox1.txt 🧪 Testing in a Lab Setting (Legally and Ethically) Since your use case is testing an isolated Nortel Meridian PBX (not connected to PSTN), here are safe, compliant suggestions: ✅ Generate MF Tones with a Tone Generator You can use software like: Audacity to create audio samples Hardware tone generators (lab-grade or amateur radio tools) Generate the MF tones for red boxing: Frequency Pair: 1700 Hz + 2200 Hz Duration: 66 ms per burst

@textfiles.com Saw a statue of infra guy with an etherkiller cable on livestream, it reminded me that an actual "RJ45-Schuko 220V" adapter exists, (about $20, but expensive for what it is)
