Ask HN: How can I prevent myself from being doxxed?
I imagine my practices are similar to many other HN readers. I follow some privacy best practices but don't generally seek anonymity online. You can google me and find my social media accounts, some articles I've written or for which I was interviewed, and figure out what city I live in. That is to say, my online persona is not entirely locked down.
Let's say I wanted to prevent myself from being doxxed. What steps could I take to make it more difficult?
- coronadisaster 6y agoWhat I do for things like Reddit and HN, is that I create a new account every few months to make it harder for them... and of course I try not to post information that could personally identify me. As a bonus, you almost stop caring about karma points ;) But of course the provider could still doxx you unless you take some additional steps to stay anonymous (like Tor, maybe).
- yyyuutt 6y agoI've started doing this too. Also email every few years now. Its nice not to care about karma.
- wtt604 6y agoStart new accounts with no reference to your old ones, your name or your location. Be careful about what you put online publicly. I think most people would be horrified at what the likes of Facebook, amazon or google knows about them.
- disposekinetics 6y agoI'd add to this use some sort of random word generator to come up with usernames since humans are bad at not picking patterns.
- searchableguy 6y agoCreate many accounts similar to your current ones or buy existing accounts with activity and change their information to be similar to yours. Muddy the water enough that anyone googling your real name can never guess you and misdirect people into clicking unsafe content. You will leave traces of information no matter how hard you try if you spend enough time on any site. Btw, did you know that even if you ask dang to rename your account - people can easily find you by searching on hn.algolia.com because they don't auto update indexes on renames? Same for many other sites. There are many indexes and archives that never update old data and won't care about GDPR requests.
- PopeDotNinja 6y agoOne approach is to simply not care if you are doxxed. What would really happen if someone figured out who you are? If the answer is not much, maybe don’t worry about it. This approach makes less sense if you are saying things that will get you in hot water.
- cardamomo 6y agoI'm not likely to say things that will get me in hot water, and I'm not a public figure by any means. That said, I see doxxing as a tactic increasingly employed against those who participate in political activism, which, like many, I am increasingly involved in.
- ggggtez 6y agoThis is a key point missing in your original post. If being politically active using your real name or real face is required, you'll need to just accept that people will be able to tie your name and face together eventually. You can additionally try to make yourself not stand out in real life: Choose a non-flashy style of dress. Black hoodie, hat, glasses, mask. Something that dozens of other people will be wearing at such events.
- userbinator 6y agomask It's interesting how the virus has caused far more widespread acceptance of wearing a mask in public, something that would arouse suspicion only a year ago. Covering most of your face no longer causes others to notice you.
- cutemonster 6y ago> If being politically active using your real name or real face is required, you'll need to just accept that people will be able to tie your name and face together eventually That might be fine, need not be a problem. (Maybe) Instead, he or she (or others in politics) might get doxxed about things unrelated to politics that s/he wants to keep private. Which might have worse consequences if beinga bit well known because of politics
- coderobe 6y agoEasy, just dox yourself first.
- xenocyon 6y agoIt depends on what you mean by being 'doxxed'. It is trivially easy to find out what city I live in and a few other non-identifying details. It's harder to pinpoint my real name or address without the active cooperation of website owners (and maybe not even then). Miniscule levels of risk are not worth worrying about, unless you are a figure in the public spotlight or likely to be a person of interest to police or intelligence orgs, in which case you should probably seek advice specific to your situation.
- cardamomo 6y ago> in which case you should probably seek advice specific to your situation This is really the key takeaway I'm getting from your comment and others so far: what is meant by doxxing and what I can do about it are very context-specific.
- anigbrowl 6y agoIf you are just worried about someone trying to steal your identity to abuse your credit or so, you probably already practice good basic security (like 2-factor authentication, not recycling your passwords etc. etc.) and have no particular need to worry about. You are more likely to have your security compromised in a corporate data breach than someone taking the time to dox you. If you get in fights online or are a member of some group that frequently experiences abuse (from inside or outside your community) then you should consider rebuilding your social media identities, giving up some of them, compartmentalizing your digital life so that your work or business don't overlap with your friendships or public persona etc. If things have gone sideways and you think people are already motivated to go after you, a determined person can pull your details together very quickly with a mixture of software tools, access to commercial databases, and some detective work. It's not difficult for someone with experience. In such a situation you should probably work with a commercial service like https://privacyduck.com https://privacyduck.com which will do the work of erasing your digital footprints. It's not cheap, last time I looked they charged $600/year or so and depending on your circumstances and vulnerability that might need to be budgeted as an ongoing expense. I'm sure there are other competitors int he same field but am not sufficiently informed to make comparisons.
- cardamomo 6y agoIt sounds like auditing my digital life might be a starting place. By understanding what others in various circles see of me, I can begin to better compartmentalize my presence online. I'm grateful that I don't have any need for a commercial privacy service right now. I wish we lived in a world where such a service weren't necessary, but that doesn't seem to be the direction we're heading.
- an_opabinia 6y ago> giving up some of them This is the way. Ask yourself if you really need an online presence or to be part of fights online.
- strombofulous 6y agoI'm looking at their list of websites https://www.privacyduck.com/services/ https://www.privacyduck.com/services/ and it looks like this is pretty similar to services that will pay to remove your mugshot from the internet... It will probably help deter people who aren't trying super hard but it's unlikely to actually help defend a dedicated attacker
- batch12 6y agoThis is an interesting question. Given your admission that your identity is loosely linked to your online accounts, I don't think it's possible to prevent someone from doxxing you-- someone just needs to tie it all together. I agree with sibling comments here that the only way to really prevent someone from identifying you from your online personas would be to start over. If you want to truly be anonymous, you need to build these new personas with OPSEC in mind. The process includes 5 general steps: 1. Identify information you feel is critical. In your case, this could be anything that ties your online activity to your real life identity. 2. Identify your threat. This can be simple or complex depending on your needs. Are you concerned about hiding from pissed off gamers, hacktivists, or a nation state? Knowing the enemy you face will help you better understand their potential capabilities to find out information about you and how they could use this information. 3. Assess your vulnerabilities. Look at yourself from the viewpoint of the attacker. What information would you use to dox yourself? 4. Assess your risk. This can also be pretty involved depending on your vulnerabilities and threats. What could someone do with this information? How bad could you be hurt? 5. Apply countermeasures. Figure out how you can mitigate the risk you found above. This may include closing old accounts, creating new accounts, creating alternate personas, disinformation, heading off potential impact from a dox, etc. Hope my ramblings helped.
- cardamomo 6y agoFortunately, I'm just asking this question out of curiosity right now. Putting this in an OPSEC perspective makes the problem a lot clearer. Your reply complements anigbrowl's sibling comment, which gets into some options for countermeasures.
- gostsamo 6y agoWhat is your threat model? Whom you are hiding from and what will happen when the info leaks? If you are the generally paranoid though, never publish photos from around your home, never make online purchases with home delivery, but choose midpoints like post stations to collect them. Assume that if you type your info somewhere, it would be sold and will pop up somewhere. Currently my name, home address, and phone are published in a american data broker website. If I want them removed, I need to send them an id with even more personal data and even then they insist that it will be hidden from public view, not deleted. I need a lawyer if I want the situation delt with properly.
- cardamomo 6y agoI haven't looked into data brokers yet. (Not tonight's problem!) How did you go about verifying what data of yours they have?
- gostsamo 6y agoI just googled my name one day. It is unusual enough to have a limited number of results and this website popped up with my name, home address and phone. They must've slurped from some dodgy website where I've shopped or the like, not sure. In case that you have too much results on your name, you can add keywords like "home", "home address", "phone number", and the like. Additionally, you can add the exact values, but those will be visible for the search engine, and maybe for someone who is smart enough to go through all queries in google trends that include your name.
- miguelmota 6y agoIf it can happen, it most likely will happen if someone really wanted to (ie by doing phising attacks, looking up public records, hiring private investigators, etc), so the best thing to do is to think about what can be done to minimize any collateral damage after the fact (ie protecting your image, securing online accounts, keeping your home safe, etc), since any sensitive information (ie confidential or embarrassing) they can acquire can be used to blackmail. It's pretty hard to remain anonymous online for a long time given how everything is connected and archived on the internet these days.
- exolymph 6y agoThe easiest way is to be insignificant. But it's still no guarantee.
- cardamomo 6y agoWell, I've got that one covered!
- prostoalex 6y agoPeople have landed in hot water for something they wrote or said decades ago. I'm guessing the OP is asking for a strategy that's reasonably future-proof.
- srtjstjsj 6y agoInsignificant people? Who?
- ggggtez 6y ago1) Promptly stop saying anything interesting under your real name. Opt out of all social media except to post messages like "Congratulations on the baby!". This will prevent you from making any enemies who know your real name, and reduce the chances anyone will want to doxx you. 2) Start adopting new pseudonyms. Use a different one on every site, and a password keeper to help you stay logged in. If you happen to forget, don't worry. Treat every account as disposable. These are not "you". This is not "your brand". These are merely tools that allow to into a walled garden party wearing the mask of anonymity. 3) Do not mix your two online personas. Keep your politics, jokes, and personality in your pseudononymous accounts. Keep your boring safe opinions and pictures of dogs in your primary account. Don't talk about anything in your real life in your pseudonymous accounts, even the weather. Reserve that kind of discussion for in-person friends only. If you make a mistake, just delete the account and make a new one.
- 300bps 6y ago2a. Unique usernames per site are essential. Even better if you use common words that will have millions of hits in search engines. 4. Don’t use the same profile picture on multiple sites. Tineye will link them together.
- jimmaswell 6y agoDo people still use Tineye with the advent of Google's reverse image search?
- thatcat 6y agoyes google image doesn't do fingerprinting technique anymore, they moved to something that does categorical matching and it isn't that good for exact image matching
- mumblerino 6y agoThis is what I do. I have “work profiles” and for everything else I just come up with a username every few months, leaving behind any “karma” I don’t need. For example the username of this month for HN is mumblerino.
- aaron695 6y ago"You can google me and find my social media account" Why can i do this? Sounds like you know the problem already and want a push ;) A lot of people I know have, no photo of their face, and not their real full name, and goes without saying totally private. Use Facebooks feature to check you have no accidental public ones. Using photos people have taken from their house, I've found the location and unit numbers before. So all these need to be private if you are really worried. Wives/husbands/family are good attack vectors. Not much you can do here to begin with. But you want things locked down to at least friends of friends. I shouldn't be able to easily escalate from necessary public profiles to private ones. But it's all about working towards the goal. Just make a start. Every little bit reduces the chance you'll get doxxed. You might just have to be the stronger gazelle. Maybe privacy is dead, maybe it's about having a job you can't be fired from or a gun in the house? Some peoples incomes depend on the public profiles.
- cardamomo 6y agoPerhaps I've put too much trust in social media companies' privacy controls. I trust you can find my accounts but see very little of my profiles or posts of relevance to my offline life. Perhaps it's time to make myself less searchable.
- searchableguy 6y agoYeah. You should avoid following people directly too. That reveals a lot about you. You can make a private twitter list.
- aaron695 6y agoA real interesting point someone else makes is, it's probably like a code review. You'll find it hard to find your own errors, but it's always fun for someone else to find your mistakes.
- ggggtez 6y ago>Wives/husbands/family are good attack vectors. Not much you can do here to begin with. But you want things locked down to at least friends of friends. Fun doxxing trick: 80% of the time your "first-friend" on social media is your significant other. Honestly, if you opt out of social media, you'll save yourself a lot of headache trying to lock it down. You'll make mistakes. And if you don't, then your spouse will. Or your friend. Or your coworkers. They'll upload a photo of you, or leave their account public, or get their account hacked... The only way to win is not to play.
- AmericanChopper 6y agoIf you’re trying to prevent an online persona from being tied to your real identity, then you just have to be incredibly paranoid about anonymity. It’s not enough to hide your name, you have to consider hiding anything that makes you identifiable. If I knew somebody was a software engineer, well I wouldn’t know how to find out who they were. If I knew they were a software engineer from Arkansas who contributed to Rust projects, all of a sudden my search would have been narrowed down significantly. If you want to prevent somebody who knows your identity from finding your phone number, address, etc... good luck. Whether somebody can find that would pretty much boil down to how much effort they’re willing to invest. Source: I used to do some of these sorts of OSINT investigations as part of a fraud investigations team.
- yyyuutt 6y agoIts almost worth changing your name if you have an unusual one. It must be great to be have a name like John Smith because no one can google you to find anything interesting.
- ydnaclementine 6y agoGoogle your full name (and any variations, Edward -> Ed, etc) and remove yourself from these whitepage direcetory type websites that people can look up your past/current residences do your family a favor and remove them too
- rishabhd 6y agoRead everything ever written by thegrugq and apply it.
- Causality1 6y agoEffectively you've already doxxed yourself. The ability to associate a real name with an address without excessive effort predates the internet and these days it is even easier, so with the internet the only winning move is not to play. Stop using your real name, period. Creating fame and an online persona that can pay your bills is directly at odds with maintaining privacy.

- hartem_ 6y agoBrian Krebs (krebsonsecurity.com) has a lot of fascinating stories on his blog on doxxing and revealing identities of people for whom remaining anonymous was vital (spoiler alert: they couldn't). Keeping totally separate identities across different services is key (using unrelated usernames, avatars, emails for every service). It’s also extremely difficult and unpractical to pull off. In most doxxing cases perpetrators manage to get access to a single service and use it as a foothold to penetrate to other services. For example, someone learns your email from a forum, somehow hacks your email, gains access to Dropbox and finds the scan of your passport, driver's licence and social security card. Email in general is the key one's digital kingdom so the surest way to minimize the blast radius is to keep everything separate and unrelated. Edit: typos
- paranoidrobot 6y agoFyi: Brian Krebs. No C. https://krebsonsecurity.com/ https://krebsonsecurity.com/
- hartem_ 6y agoThank you! I fixed my comment.
- tracker1 6y ago2FA on email definitely helps... I've actually considered just scrubbing most of my online posts on social media (not that it's absolute) and using a chromebook + prepaid burner phone for new online personas per site. I've always tried to be honest about myself, my thoughts and opinions... that said, people are getting truly crazy out there.
- d3nj4l 6y agoAt the most basic level, don't say anything online you wouldn't want seen again. Not in discord, not on twitter, nowhere. Always treat anything you disclose online as if it's public knowledge from that point on. Even if you delete it, there's a tonne of third parties that archive data you post, even on more "ephemeral" services.
- pbhjpbhj 6y agoIsn't it a given that the OP still wants to take part in online society. You're comment is more like "stop your eyes stinging when you're in the pool by never going in the pool", but they're looking for mitigations not avoidance.
- d3nj4l 6y agoThat's not the same. I'm not suggesting giving up social networks. What I mean by "never say anything you don't want sticking around" is that you should never disclose things that could be used to dox you. Never give anything more than a very general general area for location, or speak about which college you went to, or where you work. Talking about hobbies is fine, preferably on multiple accounts so nobody can link them together into a complete profile.
- goatinaboat 6y agodon't say anything online you wouldn't want seen again But the rules change at random, what is perfectly fine to say one day may not be the next.
- thetechimist 6y agoIt seems to me that the whole threat of being doxxed relies on two things: (1) that you’ve done something in one sphere of life that would be reprehensible (and maybe actionable) to another sphere of life, and (2) that the unholy Russian Twitter not mob can influence that other sphere of life. It may not be possible to have different spheres of life cohabitate peacefully, especially if the doxxing involves shining light on old character flaws you’ve since remedied, but thanks to the digital world we live in, can be easily surfaced. I’d say “get off social media forever” to at least prevent your self 20 years in the future having this same worry about whatever it is you are innocently sharing this month, but that always seems to draw a gasp from people who apparently can’t imagine life without the internet. Seems to me that everyone who has ever been doxxed is doing “something” that draws attention to them. That doesn’t make it right, but I haven’t heard of doxxing of any quiet Amish families, or guys building cabins in the woods minding their own business. It’s usually some loudmouth on some open source software forum, or some politician’s operative, or someone being a potential whistleblower. What you are asking is, in essence, how can I keep from getting punched in the mouth? It’s not too difficult, if you think about it. Someone randomly punching you in the mouth “for no reason” is about as statistically probable as being struck my lightning twice in the same week. Some people attack punches more than others. I’m not saying it’s right, or even deserved. Just that there are life choices that can increase the odds. Maybe what you’re really asking is how can I avoid the risks of some life choices I am making or want to make? All the advice here will only partially mitigate the risk. The only real way to eliminate it would be to make different choices to stop unwanted attraction. I somewhat laughed at all the “privacy” tips here. My friend, if you tick off the wrong person, they will find you or hire someone good to do it for them. And if doxxing is their chosen revenge, you can’t choose to then decide to be a quiet mild-mannered ordinary citizen when you already opened your mouth and drew attention to yourself. I’m sure everyone who flips someone off across the street wishes the same when they see the scrawny guy reach into his jacket and pull out a gun.
- dcow 6y agoFind the courage to post under your real identity. Society can’t cancel everyone. In my experience whatever political activism you’re engaging in (you mentioned as much in a sibling comment) will benefit far more from association with a real humans than with “internet commenters”. Politics happen in the real world, the internet is not representative in that respect. There are very few things that require true anonymity, and in a liberalist society political speech is not and should not be one of them, despite trends of late. The only effective response is to fight back and speak up for what you believe is right. Don’t be a coward. I mean this in the most sincere way possible.
- ppf 6y agoWhy would you let an online hate mob ruin your real life? They generally have little relation to reality, and there's a decent chance they themselves are just being manipulated and used by others. I do feel that I have a place in some online battles (or I'm just yelling into a whirlwind that someone else is controlling, but it can be fun), but I never link any of my identities. I take the stance that ideas are more powerful than solid identities. Edit: Yes I agree, real world actions are much more powerful, and we should all spend less time online.
- auganov 6y agoWell, yes, why would you let them? I don't want to live a life which could be ruined by a mob simply pointing out something I have said. I can't help but wonder if people afraid of "doxxing" are paranoid or really posting stuff they'd never say in person (in which case you probably don't want to be posting them). I understand that people get unfairly fired for social media posts. But that's what it is, an unfair firing. Why work at this kind of a place? And if you're very open about your beliefs you probably won't get yourself into this kind of a situation in the first place.
- CJefferson 6y agoPeople die from doxxing, by getting "swotted". I have a friend who had death threats sent to her parents. These people are vicious and relentless.
- ppf 6y agoDon't use your real name online. I don't have any complicated privacy best practices, I'm just not on social media and don't use my real name online if I can at all help it. Edit: Sounds like it's too late for you, but don't be an activist online using your real name unless you have some real, physical security.
- ghufran_syed 6y agoI’m actually trying to address this problem by creating a place for “kind, clear and constructive” discussion online, which uses anonymous identities, so that all users can express themselves in safety. Of course, the hard thing is to have both high quality discussion and anonymity, take a look at conferacity.com if that sounds interesting.
- srtjstjsj 6y agoDoesn't moderation solve the quality problem? Content is only low quality when the admins intentionally don't moderate.
- ghufran_syed 6y agoYes, but what we’re really trying to see is what happens if essentially everyone is a moderator? Or more specifically, what if the only people who can take part in the discussion are those who can care enough about high quality discussion to ensure that they and others adhere to some set of principles that encourage that kind of discussion. Those are obviously the kind of people who should be moderators, but if the whole community of contributors is that kind of person, maybe you could maintain the quality of the discussion as you scale? Of course, you’d grow much slower, and maybe it’s impossible to get that kind of site to a critical mass of contributors. But it seems worth trying :)
- Hakashiro 6y agoInterestingly, nobody seems to have talked about email. I run my own mail server, and I have a domain registered for handling incoming mail. Every single website, and I mean every single one, has a different email address under that domain. Now, while it could be relatively easy to correlate all usernames with domain part of the email, I make it as difficult as possible. Additionally, some handles are further separated. For example, my professional handles (so stuff I use at work but on my name, my GitHub public email, and similar stuff like that) are under other domain names from a professional (paid) email service. And even those aliases get changed over time (damn you automated email crawlers). So even if the database of a website was leaked and my mail was in that database, I would , as soon as I’m made aware of the breach, delete the account immediately and instruct my mail server to discard all incoming mail to that address. Of course, every online identity of mine has a different name. This onr has a Japanese name, but I have others with common American names, tongue twisters, and sometimes keysmashes. Good luck correlating it all.
- tracker1 6y ago1) get a "burner" cell phone, pay in advance service that isn't tied to you. Use cash to buy "gift card" or prepaid ahead of time for anything you do with this phone or online. Disable location tracking. 2) get a chromebook or other cheap laptop that isn't connected to "you" Use the laptop and phone for anything you do online. Do not connect to public wifi, or use the accounts on other devices or your personal accounts on these devices. You should be able to stay relatively anonymous this way. You will have a phone and laptop to run whatever operations/statements or other activities you want to remain private from your real life person. You may want to go a step farther and use a pre-paid VPN service for all activities as well. But by all means, don't mingle your devices...
- 082349872349872 6y agoHave your lawyer transact your business. Have your holding companies own shell companies that own your assets. The above is not complete snark: a friend's brother, whose daughter's fiesta de quinceañera I'd attended, was put in a coma working full-time for a fellow who employed two full-time accountants as part of his "family office" but who was not only too cheap to carry insurance but then even explicitly said the brother, as an independent contractor, should've had his own and refused to contribute anything towards his medical bills. I spent an afternoon trying to track down assets, and the structure I managed to reveal was ... interesting.

- 082349872349872 6y agothat following recommendations of the first para makes doxxing difficult (the second para is to say I can confirm).
- AnimalMuppet 6y agoDoxxing is usually about revealing a person, not their assets. The structure you describe is perhaps useful for protecting one's finances, but not so much for protecting one's personal identity. I mean, you know who this guy actually is.
- grimzucchini 6y agoOne thing: Delete url of your HN bio with information about who you are and hide your real name in the footer your website.
- m3kw9 6y agoEssentially any info you have posted that you remember that can be linked to any of your real ID can be traced to you. Sometime it doesn’t need to be public as hackers sell a lot of these info from hacked sites. I would say difficult to hide unless you don’t really use the internet or you are so careful it takes the joy out of it.
- lazyant 6y agoMaybe adding false information? Harder in blog articles if you already have an identity and a real name, but if you are in twitter or reddit, you can post about fake locations, hobbies, family members etc. This way at least is harder to be doxxed by automated tools and add some plausible deniability.
- RickJWagner 6y agoMy technique is to use my real name and offer only opinions that I think are quite reasonable. Of course I still run risks, but I imagine everything is knowable to someone determined enough to go looking for you. I'd hate to have posted something I wouldn't be proud of later.
- AnimalMuppet 6y agoThat lets you live as a person of integrity (in the sense of "integral", that is, there's only one of you). But it's not going to save you from the mob. Things that are quite reasonable can still set off the mob, because the mob is very much not reasonable.
- rurban 6y agoThe problems are not kids, the problems are grownups. Like police, border control, visa applications, which can harass you if you dare to voice your opinions. Which is a problematic turn of events. When I grew up, the western world was not like China or Eastern Europe, as it is now. So you didn't use pseudonyms, because your name was your brand. Only immature kids or lgbt people used pseudonyms, the rest was honest, and it helped you with your job prospects. Now a new wave of fear, bullshit and lies has taken over cooperate and public matters. You can now even trust the Eastern Europeans more than westerners.
- tmaly 6y agoAvoid politics at all costs. Stay quiet and mainly share content about food, gardening, and occasionally programming.

- probinso 6y agoYou have to define your threat model. The easiest way to not get doxxed is to always use a throwaway account. Don't bother having persistent identities online.
