What does "pwned" mean?

The word "pwned" has origins in video game culture and is a leetspeakderivation of the word "owned", due to the proximity of the "o" and"p" keys. It's typically used to imply that someone has been controlled orcompromised, for example "I was pwned in the Adobe data breach". Read more abouthow "pwned" went from hacker slang to the internet's favourite taunt.

What is a "breach" and where has the data come from?

A "breach" is an incident where data is inadvertently exposed in a vulnerablesystem, usually due to insufficient access controls or security weaknesses in the software.HIBP aggregates breaches and enables people to assess where their personal data has beenexposed.

Are user passwords stored in this site?

When email addresses from a data breach are loaded into the site, no corresponding passwordsare loaded with them. Separately to the pwned address search feature, the Pwned Passwordsservice allows you to check if an individual password has previously been seen in a databreach. No password is stored next to any personally identifiable data (such as an emailaddress) and every password is SHA-1 hashed (read why SHA-1 was chosen in the Pwned Passwords launch blog post.)

Can I send users their exposed passwords?

No. Any ability to send passwords to people puts both them and myself at greater risk. Thistopic is discussed at length in the blog post on all the reasons I don't make passwords available via this service.

Is a list of everyone's email address or username available?

The public search facility cannot return anything other than the results for a singleuser-provided email address or username at a time. Multiple breached accounts can beretrieved by the domain search feature but only aftersuccessfully verifying that the person performing the search is authorised to access assetson the domain.

What about breaches where passwords aren't leaked?

Occasionally, a breach will be added to the system which doesn't include credentials for anonline service. This may occur when data about individuals is leaked and it may notinclude a username and password. However this data still has a privacy impact; it is datathat those impacted would not reasonably expect to be publicly released and as such they havea vested interest in having the ability to be notified of this.

How is a breach verified as legitimate?

There are often "breaches" announced by attackers which in turn are exposed ashoaxes. There is a balance between making data searchable early and performing sufficient duediligence to establish the legitimacy of the breach. The following activities are usuallyperformed in order to validate breach legitimacy:

(Video) Have I been Pwned and What to do if you have been in a data breach

  1. Has the impacted service publicly acknowledged the breach?
  2. Does the data in the breach turn up in a Google search (i.e. it's just copied from another source)?
  3. Is the structure of the data consistent with what you'd expect to see in a breach?
  4. Have the attackers provided sufficient evidence to demonstrate the attack vector?
  5. Do the attackers have a track record of either reliably releasing breaches or falsifying them?

What is a "paste" and why include it on this site?

A "paste" is information that has been "pasted" to a publicly facingwebsite designed to share content such as Pastebin. Theseservices are favoured by hackers due to the ease of anonymously sharing information andthey're frequently the first place a breach appears.

HIBP searches through pastes that are broadcast by the accounts in the Paste Sources Twitter listand reported as having emails that are a potential indicator of a breach. Finding an emailaddress in a paste does not immediately mean it has been disclosed as the result ofa breach. Review the paste and determine if your account has been compromised then takeappropriate action such as changing passwords.

My email was reported as appearing in a paste but the paste now can't be found

Pastes are often transient; they appear briefly and are then removed. HIBPusually indexes a new paste within 40 seconds of it appearing and stores the emailaddresses that appeared in the paste along with some metadata such as the date, title andauthor (if they exist). The paste itself is not stored and cannot be displayed if it nolonger exists at the source.

My email was not found — does that mean I haven't been pwned?

Whilst HIBP is kept up to date with as much data as possible, it contains buta small subset of all the records that have been breached over the years. Many breaches neverresult in the public release of data and indeed many breaches even go entirely undetected."Absence of evidence is not evidence of absence" or in other words, just becauseyour email address wasn't found here doesn't mean that is hasn't been compromised in anotherbreach.

How does HIBP handle "plus aliasing" in email addresses?

Some people choose to create accounts using a pattern known as "plus aliasing" in their emailaddresses. This allows them to express their email address with an additional piece of datain the alias, usually reflecting the site they've signed up to such as test+netflix@example.comor test+amazon@example.com. There is presently a UserVoice suggestionrequesting support of this pattern in HIBP. However, as explained in that suggestion, usageof plus aliasing is extremely rare, appearing in approximately only 0.03% ofaddresses loaded into HIBP. Vote for the suggestion and follow its progress if this featureis important to you.

How is the data stored?

The breached accounts sit in Windows Azure table storage which contains nothing more than the emailaddress or username and a list of sites it appeared in breaches on. If you're interested inthe details, it's all described in Working with 154 million records on Azure Table Storage – the story of Have I Been Pwned

Is anything logged when people search for an account?

Nothing is explicitly logged by the website. The only logging of any kind is via GoogleAnalytics, Application Insightsperformance monitoring and any diagnostic data implicitly collected if an exception occurs inthe system.

Why do I see my username as breached on a service I never signed up to?

When you search for a username that is not an email address, you may see that name appearagainst breaches of sites you never signed up to. Usually this is simply due to someone elseelecting to use the same username as you usually do. Even when your username appears veryunique, the simple fact that there are several billion internet users worldwide means there'sa strong probability that most usernames have been used by other individuals at one time oranother.

Why do I see my email address as breached on a service I never signed up to?

When you search for an email address, you may see that address appear against breaches ofsites you don't recall ever signing up to. There are many possible reasons for this includingyour data having been acquired by another service, the service rebranding itself as somethingelse or someone else signing you up. For a more comprehensive overview, seeWhy am I in a data breach for a site I never signed up to?

Can I receive notifications for an email address I don't have access to?

No. For privacy reasons, all notifications are sent to the address being monitored so youcan't monitor someone else's address nor can you monitor an address you no longer have accessto. You can always perform an on-demand search of an address, but sensitive breacheswill not be returned.

Does the notification service store email addresses?

Yes, it has to in order to track who to contact should they be caught up in a subsequent databreach. Only the email address, the date they subscribed on and a random token for verificationis stored.

Can a breach be removed against my email address after I've changed the password?

HIBP provides a record of which breaches an email address has appeared in regardless ofwhether the password has consequently been changed or not. The fact the email address was inthe breach is an immutable historic fact; it cannot later be changed. If you don't wantany breach to publicly appear against the address, use the opt-out feature.

What email address are notifications sent from?

All emails sent by HIBP come from noreply@haveibeenpwned.com. If you're expecting an email(for example, the verification email sent when signing up for notifications) and it doesn'tarrive, try white-listing that address. 99.x% of the time email doesn't arrive in someone'sinbox, it's due to the destination mail server bouncing it.

How do I know the site isn't just harvesting searched email addresses?

You don't, but it's not. The site is simply intended to be a free service for people toassess risk in relation to their account being caught up in a breach. As with any website,if you're concerned about the intent or security, don't use it.

Is it possible to "deep link" directly to the search for an account?

Sure, you can construct a link so that the search for a particular account happensautomatically when it's loaded, just pass the name after the "account" path.Here's an example:

https://haveibeenpwned.com/account/test@example.com

How can I submit a data breach?

If you've come across a data breach which you'd like to submit, get in touch with me.Check out what's currently loaded into HIBP on the pwned websites pagefirst if you're not sure whether the breach is already in the system.

What is a "sensitive breach"?

HIBP enables you to discover if your account was exposed in most of the databreaches by directly searching the system. However, certain breaches are particularlysensitive in that someone's presence in the breach may adversely impact them if others areable to find that they were a member of the site. These breaches are classed as "sensitive"and may not be publicly searched.

A sensitive data breach can only be searched by the verified owner of the email addressbeing searched for. This is done via the notification systemwhich involves sending a verification email to the address with a unique link. When that linkis followed, the owner of the address will see all data breaches and pastes theyappear in, including the sensitive ones.

There are presently 48sensitive breaches in the system including Adult FriendFinder (2015), Adult FriendFinder (2016), Adult-FanFiction.Org, Ashley Madison, Beautiful People, Bestialitysextaboo, Brazzers, Carding Mafia (December 2021), Carding Mafia (March 2021), CrimeAgency vBulletin Hacks, CTARS, CyberServe, Doxbin, Emotet, Fling, Florida Virtual School, Freedom Hosting II, Fridae, Fur Affinity, Gab and 28 more.

What is a "retired breach"?

After a security incident which results in the disclosure of account data, the breach may beloaded into HIBP where it then sends notifications to impacted subscribers and becomessearchable. In very rare circumstances, that breach may later be permanently remove from HIBPwhere it is then classed as a "retired breach".

(Video) Has My Online Account Been Hacked - haveibeenpwned Tool Walkthrough

A retired breach is typically one where the data does not appear in other locations on theweb, that is it's not being traded or redistributed. Deleting it from HIBP provides thoseimpacted with assurance that their data can no longer be found in any remaining locations.For more background, read Have I Been Pwned, opting out, VTech and general privacy things.

There is presently 1retired breach in the system which is VTech.

What is an "unverified" breach?

Some breaches may be flagged as "unverified". In these cases, whilst there islegitimate data within the alleged breach, it may not have been possible to establishlegitimacy beyond reasonable doubt. Unverified breaches are still included in the systembecause regardless of their legitimacy, they still contain personal information aboutindividuals who want to understand their exposure on the web. Further background onunverified breaches can be found in the blog post titledIntroducing unverified breaches to Have I Been Pwned.

What is a "fabricated" breach?

Some breaches may be flagged as "fabricated". In these cases, it is highly unlikelythat the breach contains legitimate data sourced from the alleged site but it may still besold or traded under the auspices of legitimacy. Often these incidentsare comprised of data aggregated from other locations (or may be entirely fabricated), yetstill contain actual email addresses unbeknownst to the account holder. Fabricated breachesare still included in the system because regardless of their legitimacy, they still contain personal information about individuals who want to understand their exposure on the web.Further background on unverified breaches can be found in the blog post titledIntroducing "fabricated" breaches to Have I Been Pwned.

What is a "spam list"?

Occasionally, large volumes of personal data are found being utilised for the purposes ofsending targeted spam. This often includes many of the same attributes frequently found indata breaches such as names, addresses, phones numbers and dates of birth. The lists areoften aggregated from multiple sources, frequently by eliciting personal information from people with the promise of a monetary reward.Whilst the data may not have been sourced from a breached system, the personal nature of theinformation and the fact that it's redistributed in this fashion unbeknownst to the ownerswarrants inclusion here. Read more about spam lists in HIBP.

What is a "malware" breach?

Data breaches in HIBP aren't always the result of a security compromise of an online serviceand occasionally, data obtained by malware campaigns is also loaded. For example, the US FBI and Dutch NHTCU provided HIBP with data from the Emotet malware in April 2021.The risk posed to individuals in these incidents is different (their personal device may becompromised) hence the presence of this flag in HIBP.

What does it mean if my password is in Pwned Passwords?

If a password is found in the Pwned Passwords service, it means ithas previously appeared in a data breach. HIBP does not store any information about who thepassword belonged to, only that it has previously been exposed publicly and how many times ithas been seen. A Pwned Password should no longer be used as its exposure puts it at higherrisk of being used to login to accounts using the now-exposed secret.

I searched for my email address on HIBP and then I was hacked, what gives?!

First of all, searches are not logged so there's no collection ofaddresses. Any searches that are performed are done so over an encrypted connectionso nobody has access to the web traffic other than those hosting the HIBP services. Even ifthey did, it's only an email address and not enough to gain access to someone'sonline accounts. If Pwned Passwords has also been used to search fora password, it's anonymised before being sent to HIBP so even a search for both email addressand password doesn't provide a usable credential pair. Correlation does not imply causation;it's a coincidence.
