What happened?

On February 8, 2019, our engineering team became aware of a potential security issue affecting certain user profile data. We immediately launched a comprehensive review of our systems to understand the nature and scope of the issue. We engaged a third-party expert to assist us in our investigation and are coordinating with law enforcement authorities on this matter.  

Based on our investigation to date, we believe that an unauthorized party gained access to our systems and acquired partial user data on approximately July 5, 2018. We’ve concluded this issue affected certain information that users provided when filling out their user profiles, as listed below. Our engineers are closely monitoring our platform and we’ve found no evidence to date of any recurrence of this issue.

As a precaution, we are requiring all users to reset their 500px account passwords. A notification email will provide instructions to affected data subjects on how to reset their passwords.

A system-wide password reset is currently underway for all users, prioritized in order of potential risk, and we have already forced a reset of all MD5-encrypted passwords.

What type of user data was affected?

  • Your first and last name as entered on 500px
  • Your 500px username
  • The email address associated with your 500px login
  • A hash of your password, which was hashed using a one-way cryptographic algorithm
  • Your birth date, if provided
  • Your city, state/province, country, if provided
  • Your gender, if provided

How do I know if I was affected?

If you were a 500px user on or prior to July 5, 2018, you have been affected.

We are in the process of notifying all users via email as well as onsite and with mobile notifications, however, given the volume of users affected, there may be delays in the notifications you receive.

Regardless of whether or not you were directly affected, given the nature of the personal data involved, we are alerting you to this matter so you can take steps to help protect yourself against the risk of phishing, spam, and other misuse of your information as a result of this issue. We recommend you change your password on any other website or app on which you use a password that is the same as or similar to your password for your 500px account.

When did you first learn of the security issue?

On February 8, our engineering team learned of a potential security issue and began investigating right away.  

What have you done to fix this?

Given the nature of the personal data involved, our priority was to first ensure:

1) the security of our system;

2) that our users’ data is secured from further breaches and unauthorized access of the accounts first and foremost, followed by communication to our users, followed by public communications.

  • We have vetted access to our servers, databases, and other sensitive data-storage services.
  • We have and are continuing to monitor our source code, both public-facing and internal, to protect against security issues.
  • We are partnering with leading experts in cyber security to further secure our website, mobile apps, internal systems, and security processes.
  • We are modifying our internal software development process.
  • We are continuing to upgrade our network infrastructure.

What data wasn’t taken?

At this time, there is no indication of unauthorized access to your account, and no evidence that other data associated with your user profile was affected, such as credit card information (which is not stored on our servers), if used to make any purchases, or any other sensitive personal information.

Have you alerted law enforcement?
We have alerted law enforcement, in addition to retaining a security firm to assist us in the investigation and next steps.


How can we trust this won’t happen again?

Going forward, we will continue to enhance our security measures to help keep your data safe and we are implementing additional measures to help prevent this type of incident from reoccurring.

We are continuing to upgrade our network infrastructure. Over the last 12 months, we have undertaken a major upgrade to our network infrastructure—this project is nearing completion, and will also offer a significant increase in security.

I want to delete my 500px account.

Keep in mind, deleting your 500px account does not affect whether your information has been compromised by this breach. The steps for deleting your account can be found here:

How do I delete my account? 

As per our privacy policy, we may preserve your data if necessary to comply with specific legal obligations.

How can I get a copy of all my data from 500px?

500px can send you an archive of your data via email. Please send a request to help@500px.com and we can fulfill the data request within 72 hours of our team confirming receipt of the email.

I didn’t get the password reset email.

If we invalidated your password, you will be prompted to reset your password the next time you try to log in to 500px with a password. We are contacting affected users as soon as possible over the next few days.

The link in the email doesn’t work.

If we invalidated your password, you will be prompted to reset your password the next time you try to log in to 500px with a password. We recommend doing so at your earliest convenience.

Why do I have to reset my password/why can’t I log in?

While we have password security measures in place, we are taking additional steps to protect your personal data. As a precaution, we are requiring all users to reset their 500px account passwords.

Why do I have multiple emails and links?

You may have received multiple messages or password reset prompts from 500px. This is because we are taking every precaution to ensure we have made all of our users aware of this incident.
