  • Understand the difference between a joke and an insult.

  • Don't get baited into back-and-forth insults. We are not animals.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn, no politics, no trolling or ragebaiting.
  • Don't come looking for advice, this is not the right community.
  • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.

    Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility.

    Listen, the only folks you put your black hat on for are folks who try to phish you. And you report your findings anonymously to CISA.

    That's how the recent USPS scams, the EZ pass scam, and the AAA scam got untangled. Be safe.

    You put on your black hat at work when your boss tells you to do so on objects under your teams ownership. Don't be stupid.

    Other than that, don't be an idiot. Stick to BBPs and VDPs, Educational labs, shit you own, etc. Nothing more than a totally unglamorous fine, or worse, awaits you.

    Sincerely, a veteran of cybersecurity.

    You put on your black hat at work when your boss tells you to do so on objects under your teams ownership.

    But that's white hat, not black hat.

    In my country, simply scanning for hosts/IP addresses could get you implicated, since IP addresses are under certain circumstances regarded as PII according to the GDPR. So... stay safe xD

    Unauthorized port scanning. If your job involves networking or cybersecurity, you're contracted to do pen-testing, or your activities are limited to a network you own, you'll be fine.

    Definitely! But speaking of pen-testing, there are some "funny" stories about pen-testers getting temporarily apprehended and questioned by security or the authorities when communication between their employer and their client wasn't done properly. I wonder if the IT Crowd at my agency would notice if I did an unsanctioned, unauthorized port scan from my office desktop...

    Yep, true story. Besides from the particulars in the GDPR that affects EU citizens, I think there is a more generalized disclaimer in the nmap manual about doing certain scans.

    No US laws currently criminalize port scanning.

    So go learn SEToolkit instead I guess.

    The US isn't the only country; this is a GDPR thing.

    Rotate your MAC every 3-5 minutes on a random interval, or even more often. Stay safe.
