    Unfortunately that wouldn’t work as this is information inside the PDF itself so it has nothing to do with the file hash (although that is one way to track.)

    Now that this is known, It’s not enough to remove metadata from the PDF itself. Each image inside a PDF, for example, can contain metadata. I say this because they’re apparently starting a game of whack-a-mole because this won’t stop here.

    There are multiple ways of removing ALL metadata from a PDF, here are most of them.

    It will be slow-ish and probably make the file larger, but if you’re sharing a PDF that only you are supposed to have access to, it’s worth it. MAT or exiftool should work.

    Edit: as spoken about in another comment thread here, there is also pdf/image steganography as a technique they can use.


  • Sucks that I have to preface but people can be jumpy here. This is genuine curiosity, I’m actually asking, because it’s really probably something I should already know. Can you explain the nuance to me please?


    My understanding, speaking mostly of apps/websites, I know jobs can be much different:

    Most places have the first factor as a password.

    First factor (or “login”) = username+password pair.

    For the longest time that was all there was, “your login” was just a login, which meant a username and password combination. Then 2FA/MFA (“2 factor authentication / multi-factor authentication”) came along in the form of username+password combo plus SMS/email/Google Authenticator/Yubikey/etc to verify as the 2nd form of authentication. You can have 3FA 4FA 5FA whatever if you want and if it’s supported by the app/website. So 2FA is MFA, but MFA is not necessarily 2FA.

    I know jobs can be set up a lot differently.



  • I think it’s not humiliating, but if you know someone, you should have some idea what they like/their interests are. Getting a small gift that fits them shows that you spent at least a small amount of time and thoughtfulness picking out or making the gift. If you don’t know the person, sure, cash/gift card.

    Although I think it’s becoming less common to have the space or ‘the time’ (but we could prob all spend 30 mins less each day doing nothing on our phones) so giving physical actual gifts are becoming less common, and also due to the economy the idea of ‘mandatory days of gift giving’ is a bit off-putting. People love getting personalized gifts from people who create things, but far less people today ‘have time’ to learn a hobby where they create things in physical space.

    Less “Fuck you here is $10” and more “Here is $10 as agreed upon by the social contract unwritten by the masses who came before us, I didn’t have any clue what you might like or want and didn’t think to ask.”

    Some people gladly prefer cash/card. I am one of those people. We will make that known well ahead of time.



  • The upper crust and intelligence apparatus was incredibly uncomfortable with OWS for obvious reasons.

    Preface: short (2min) video of an Occupy meeting near the end https://www.youtube.com/watch?v=W81A1kTXPa4

    Pre-occupy, gender identity and race-based issues were known but not talked about a great deal in the public sphere. They weren’t the core identity of a large number of people, and they were something that was ‘allowed’ to be discussed without blind following or rage.

    During occupy, OWS organizers started what they called an ‘egalitarian stance’, which was a way to reframe the available classes to fight against in class warfare, were those more privileged than you (race, gender, identity politics) instead of financial privilege. If you were a white male, whether disabled or had a speech impediment or whatever, you were more privileged than anyone and you lost your rung in the ladder, you were now the lowest class. White women were just above you. Minority groups (race and gender, poverty level not included) became the prevailing upper-class and had the most right to speak.

    OWS quickly lost momentum after a number of changes like this, and the conversation was no longer about class warfare, but about privilege, meaning only race and gender (initially). I believe there were leaked documents (unsure if verified) that the FBI was seeking, or had gained, access to OWS leadership positions. It seems obvious they would attempt it. This is something someone will have to confirm or correct me on, because a quick search isn’t pulling the documents and I need to run.

  • Friendly reminder that Bluetooth has a larger network stack than Wi-Fi. Much more code, much larger available attack base. There have been many numerous Bluetooth vulnerabilities that allow remote code execution or theft of files.

    This is truly becoming a surveillance state, in no way that can be debated. That want to be able to access everyone’s innermost thoughts (texts, notes, recordings, calendars, contacts, photos, you get it) without any chance of someone being able to protect against it.

    Reminder that Google was the 2nd or 3rd company to commit to NSA’s PRISM program of feeding American’s data for future analysis.
