Bullhorn’s services went offline on 16th October 2026 due to a cyber incident, here’s the original report at the time – Bullhorn Cyber Incident October 2026.
The majority of Bullhorn’s services are back online as at 4th November, but there are still some important items to note.
Some of our customers’ API user accounts have had their passwords changed automatically by Bullhorn. This means that if the password no longer authenticates, your Bullhorn service is not able to perform it’s task.
We have been contacting customers who have been affected, a quick password reset and they are back on their way.
There are many Bullhorn job board plugin customers who self host, if you find that your jobs suddenly stop syncing, please get in touch. It’s a quick and easy fix to change the API password and get your jobs syncing back in to your website.
Potential big disruption incoming as a result of the cyber incident
Bullhorn are considering updating ALL API keys, not just those for select customers. This means that every product and service you have that utilises the API will cease to work, until the new API keys have been input.
We have been working with the Bullhorn API since 2012 and as such have almost 1000 customers and many more projects using the Bullhorn API. Updating every single one of these projects with new keys is going to be quite a task.
If Bullhorn do decide to update all keys, hopefully they utilise a staged approach to give agencies such as ourselves a fighting chance to update all projects quickly and minimize any down time for our and their customers.
Which customer and projects are affected?
If all API keys are changed, it will affect everyone.
What do we need to do if API keys are updated?
Projects we host, we will take care of updating the keys. You simply need to provide the new key info and we’ll do the rest. It’s a quick job, but multiplied thousands of times turns a quick project into a large task.
For those customers self hosting, you have a handy interface where you can insert your new keys. Simply add the new keys and press save. The system will then utilise these new keys and get you back up and running.
What else do we know about the Bullhorn Cyber incident?
Not much at this point, our blog post over on our Recruitment Swiss Army Knife website – Bullhorn Cyber Incident Update 3 November – has more information on this, but there has been no official word on whether data was compromised.
