OSINT › Module 10 › Lesson 1
Have I Been Pwned and Mozilla Monitor
Check YOUR email on official monitors — never paste other people's addresses into random checkers.

https://haveibeenpwned.com/ and https://monitor.mozilla.org/ for YOUR inbox. GATE 192.168.0.1.
Opening
A breach list is a memory of passwords you reused. Official monitors are the door. Random “checkers” are often the leak.
Have I Been Pwned (HIBP) at https://haveibeenpwned.com/ and Mozilla Monitor at https://monitor.mozilla.org/ tell YOU whether YOUR address appeared in known breaches. You type YOUR email in those official sites. You do not paste a classmate's address. You do not paste a celebrity. You do not upload a stolen list to a shady “breach checker.” You do not download dumps. Original Cyberlium Topic 12 capstone start. Teaching bind never 0.0.0.0. Next: IntelX Dehashed and Why You Never Download Dumps.
1. Official monitors, YOUR address, no third-party pastebins
HIBP is Troy Hunt's public notification service. Mozilla Monitor is Mozilla's notification product. Both exist so people can rotate credentials. Cyberlium's lab is: open the official page, use YOUR email from t12-scope.yaml, write what the UI said in chmod 600 notes (redact the address if you will share the file). That is enough.
Random Google ads that say “check if you were pwned — paste 10,000 emails” are not HIBP. Pasting other people's emails is both unethical and often against those sites' intent. IntelX and Dehashed wait for the next lesson as commercial names — still no dumps.

2. What a hit means, and what it does not
A hit means that address was in a dataset HIBP or Monitor knows. It does not mean you must download the dump “to see the password.” Rotate unique passwords and enable MFA on accounts YOU control. Write “rotated / not yet / no hit” in notes. Do not paste passwords into chat.
No hit is not a lifetime guarantee. It is “not in these catalogs today.” Keep using unique passwords anyway.
3. GATE is still not an email lab on the router
If 192.168.0.1 was Router Admin, STOP. Do not hydra it for “admin@local.” Breach monitors are cloud UIs plus YOUR notes. Teaching toy stays
Never Sherlock strangers as a way to find emails to paste into HIBP. Module 2 was YOUR handle only; that rule did not expire.
4. What you ship: official HIBP/Monitor result for YOUR email only
Bookmarks https://haveibeenpwned.com/ and https://monitor.mozilla.org/. UI result for YOUR address (redacted in notes if needed). chmod 600. No other people's emails. No dump download. DEMO GATE.
5. What you record before the next lesson
Date. Breach check = official UI + MY email. NEVER random checkers. File t12-m10-l01-hibp.txt.
6. Wrong vs right: strangers vs identifiers YOU own
Worked failure — same OSINT word, opposite target. Right never needs a classmate or a dump site.
Wrong
Paste a class roster into a random checker. Download a dump to “see the hash.” Sherlock a stranger then HIBP them.
Right
Official monitors, YOUR inbox. Next: IntelX Dehashed and Why You Never Download Dumps.
Mission: check YOUR address on official monitors
1) / STOP if router. 2) Open HIBP and Mozilla Monitor. 3) Check YOUR email only; write hit/clear/skipped chmod 600. Never paste others. Never download dumps. Never Sherlock strangers.
Stuck? Ask Cyberlium AI Mentor
If you do not want your email in notes, write “checked in UI, redacted.” Do not use a classmate's address as a stand-in.
