Use the “passwords” feature to check if one of yours is compromised. If it shows up, never ever reuse those credentials. They’ll be baked into thousands of botnets etc. and be forevermore part of automated break-in attempts until one randomly succeeds.

    As someone who consults in the IT Security space, It’s bad out there. Contractors and BYOD companies are downright sheepish in asking their outsourced employees to do anything security-related to their devices. The biggest attack vector is allowed unfettered remote access (and therefore the whole company and any bad actors are also granted unfettered remote access)

    I still can’t get over how quickly companies-at-large have abandoned VPN Servers (removing network trust from the list of options as well)

    I’m down to managed browsers via IdP, and I just can’t wait for the objections to that as well. People out here offering their faces to leopards. Certificate-based MFA on all the things IMO - passwords shouldnt matter (but six digit MFA codes aren’t immune to fake landing pages and siphoned MFA tokens that don’t expire)

          Synthient wasn’t hacked, as a security company, they aggregated tons of stealer logs dumped to social media, Telegram, etc.

          They found 8% of the data collected was not in the HIBP database, confirmed with some of the legitimate owners that the data was real.

          They then took that research and shared it with HIBP which is the correct thing to do.

          I was also thrown off by the title they gave it when I first saw it, a security company being hacked would be a terrible look. but they explain it in the article. Should probably have named it “list aggregation” or something.

    Protip for the room: Use a password manager with a unique password for every service. Then when one leaks, it only affects that singular service, not large swaths of your digital life.

      I was thinking about this earlier. The password manager browser plugin I use (Proton Pass) defaults to staying unlocked for the entire browser session. If someone physically gained access to my PC while my password manager was unlocked, they’d be able to access absolutely every password I have. I changed the behavior to auto-lock and ask for a 6-digit PIN, but I’m guessing it wouldn’t take an impractical amount of time to brute-force a 6-digit PIN.

      Before I started use a password manager, I’d use maybe 3-4 passwords for different “risks,” (bank, email, shopping, stupid shit that made me sign up, etc). Not really sure if a password manager is better (guess it depends on the “threat” you’re worried about).

      Edit: Also on my phone, it just unlocks with a fingerprint, and I think law enforcement are allowed to force you to biometrically unlock stuff (or can unlock with fingerprints they have on file).

        Yes, it is better. The likelihood that someone will physically access your device is incredibly low, the likelihood that one of the services in your bucket gets leaked and jeopardizes your other accounts is way higher.

        I set mine to require my password after a period of time on certain devices (the ones I’m likely to lose), and all of them require it when restarting the browser.

        it just unlocks with a fingerprint, and I think law enforcement are allowed to force you to biometrically unlock stuff

        True, but it’s also highly unlikely that LE will steal your passwords.

        My phone requires a PIN after X hours or after a few failed fingerprint attempts, and it’s easy to fail without being sus. In my country, I cannot be forced to reveal a PIN. If I travel to a sketchy country or something, i switch it to a password unlock.

      I use a “password pattern”, rather than remembering all the passwords, I just remember a rule I have for how passwords are done, there are some numbers and letters that change depending on what the service is so every password is unique and I can easily remember all of them as long as I remember the rules I put in place

          That is assuming that someone will sit there and try to decrypt password rules for that specific person. Chances of that happening are basically 0, unless they are some sort of a high interest person.

            If there’s a leak with multiple services, it’s possible some script kiddie will flag it as having a pattern. I’m guessing the rule is simple enough that an unsophisticated attacker could figure it out with several examples.

            It’s way better than reusing passwords, but I don’t think it’s better than a password manager, and it takes way more effort esp given all the various password rules companies have (no special characters, must have special character, special character must be one of…). If you’re paranoid, use something like keypassxc that’s just a file.

          What’s more likely, a password manager gets a breach or someone targets only me and manages to find out multiple passwords across multiple services and cross compares them works out what the random numbers and letters mean…

            I don’t know your rule, but when I hear this, usually it includes the name of the service or something, so a script kiddie armed with a levenstein distance algo could probably detect it.

            That said, the “safer than the person next to you” rule applies here. You’re probably far enough down that list to not matter.

            As for password manager breaches, the impact really depends on what data the password manager stores. If all decryption is done client-side and the server never gets the password, an attacker would need to break your password regardless. That’s how Bitwarden works, so the only things a breach could reveal are my email, encrypted data, and any extra info I provided, like payment info. The most likely attack would need to compromise one of the clients. That’s possible, but requires a bit more effort than a database dump.

        I’ve found that there are a handful of passwords that you need to remember, the rest can go in the password manager. This includes the password for the password manager, of course, but also passwords for your computer/phone (since you need to log in before you can access the password manager), and your email (to be able to recover your password for the password manager).

        You are also correct that length is mostly what matters, but also throwing in a random capitalization, a number or two, and some special character will greatly increase the required search space. Also using uncommon words, or words in other languages than english can also greatly increase the resistance to dictionary attacks.

          your email (to be able to recover your password for the password manager)

          If your password manager has a password recovery mechanism, that means your key is stored on the server and would be compromised in a breach. If that’s the case, I highly recommend changing password managers.

          The ideal way a password manager works is by having all encryption done client-side and never sending the password to the server. If the server cannot decrypt your password data, neither can an attacker. That’s how my password manager works (Bitwarden), and I highly recommend restricting your options only to password managers with that property.

          If you need a backup, write it in a notebook and keep it in a safe. If your house gets broken into, change your password immediately before the thief has a chance to rifle through the stuff they stole. My SO and I have shared passwords to all important credentials, so that’s out backup mechanism.

              Spammers go for the easiest targets. If you do stuff like this, they might redesign their system to make it LESS likely to send to you. Keep in mind theyre targetting the elederly, mentally handicapped, and the emotionally desperate. They specifically DO NOT want to target the educated, technologically literate, and those that will waste their time. By attempting to technologically limit them from their scams, you make it more difficult for them to target you and it makes it obvious theyre not worth your time.

              Its not about making yourself scam proof, its about making yourself an unappealing target.

              (This all applies to scam emails, dunno if it has any effect if the goal is phishing but i would imagine so. If they can phish 5 people in the time it takes to phish you, youre no longer their target.)

              Edit: this is why scam emails look obviously scammy, with misspelled words and grammarical errors. Its not a mistake, its an attempt to preemptively weed out people who want to waste their time

        Just as an example, 1Password has a secondary encryption key that they can’t even recover. If you lose it, you’re fucked. I doubt the chances of that being cracked are any good at all.

          Bitwarden has no secondary key, and the master key is never sent to the server. All they get is an email address and encrypted data. If you forget your key, your passwords cannot be accessed, which means an attacker is screwed too.

          There are tons of ways to give yourself ways to “recover” your password that don’t compromise you in a breach scenario:

          • logged in devices - they have the key decrypted and can generate a new one, re-encrypt, and overwrite the data server-side
          • store a physical copy of the password at home somewhere (notebook?)
          • share passwords with a trusted person (SO) for critical shared accounts
          • securely store an unencrypted backup of your password vault (say, on a personal computer with full disk encryption)

          Maybe that’s how 1password works, idk, but I do recommend verifying that there’s no password recovery option on whatever password manager service you use.

              Make sure whatever password manager you use doesn’t store the key on their servers. Bitwarden does this correctly (if you lose your PW, Bitwarden can’t recover it), and I’m sure some competitors do as well. LastPass apparently didn’t.

          I’ve only really been in one breach. This one is actually a breach of a “security firm” (incompetent idiots) who aggregated login data from the dark web themselves, essentially doing the blackhats’ work for them.

          This is also EXACTLY why requiring online interactions to be verified with government ID is a terrible idea. Hackers will similarly be able to gain all possible wanted data in a single location. It’s simply too tempting of a target not to shoot for.

            I currently have 110 unique user+password combos. I wouldn’t want to change all those even once, if I were breached and had used similar credentials everywhere.

            Bitwarden keeps them well managed, synced between devices, and allows me to check the whole database for matches/breaches via haveibeenpwned integration. Plus because I prefer to keep things in-house as much as possible, I even self-host the server with vaultwarden walled off behind my own vpn, instead of using the public servers. (this also means it’s free, instead of a paid service)

            To the people who didn’t read the article posted in the comment prior, basically the software installed wasn’t the legitimate software, it was a modified software that was a trojan that was forwarding passwords stored in the keepass database to a home server.

            That’s not something that the sites are going wrong, nor is it the password managers fault. That’s fully the users fault for downloading a trojan.

        A password manager is still a good idea, but you have to not use a hacked one. So only download from official sites and repositories. Run everything you download through VirusTotal and your machine’s antivirus if you have one. If it’s a Windows installer check it is properly signed (Windows should warn you if not). Otherwise (or in addition) check installer signatures with GPG. If there’s no signature, check the SHA256 OR SHA512 hash against the one published on the official site. Never follow a link in an email, but always go directly to the official website instead. Be especially careful with these precautions when downloading something critical like a password manager.

        Doing these things will at least reduce your risk of installing compromised software.

    The thing about this one is no one seems sure of the source (it appears to be from multiple sources, including infostealer malware and phishing attacks), so you don’t know which passwords to change. To be safe you’d have to do all of them.

    Some password managers (e.g. Bitwarden) offer an automatic check for whether your actual passwords have been seen in these hack databases, which is a bit more practical than changing hundreds of passwords just in case.

    And of course don’t reuse passwords. If you have access to an email masking service you can not only use a different password for every site, but also a different email address. Then hackers can’t even easily connect that it’s your account on different sites.

        More details about the k-anonimity process. https://blog.cloudflare.com/validating-leaked-passwords-with-k-anonymity/

        The short answer is that they download a partial list of passwords that hash to values starting with the same 5 characters as yours and then check if your password hash is in that list locally. This gives the server very little information about your password if it was not breached and more if it was (but then you should change it anyway), making an elegant compromise

        They probably hash the list of hacked passwords the same way your passwords get hashed and check for matches.

      The breach occurred in April 2025.

      During 2025, the threat-intelligence firm Synthient aggregated 2 billion unique email addresses disclosed in credential-stuffing lists found across multiple malicious internet sources. Comprised of email addresses and passwords from previous data breaches, these lists are used by attackers to compromise other, unrelated accounts of victims who have reused their passwords. The data also included 1.3 billion unique passwords, which are now searchable in Pwned Passwords. Working to turn breached data into awareness, Synthient partnered with HIBP to help victims of cybercrime understand their exposure.
