PayPal’s Third LHE Brings Top Global Hackers to the Virtual Stage

PayPal has been partnering with the hacker community since launching a bug bounty program in 2012 and in April 2022, they returned for their third live hacking event. As usual, PayPal showed up ready to engage the best of the best of HackerOne’s community in order to put their mobile products and apps to the test. And did they ever.

Here’s what they had to say:

“We came back for our third Live Hacking Event because we know how important these events are. Not only do we build strong relationships with the most elite hackers in the world, but they also help us prioritize the most critical mobile security processes while making sure our customers, our merchants, and their data remain protected,said Assaf Keren, Chief Information Security Officer and Vice President, Enterprise Cyber Security for PayPal. 

PayPal was joined by heavy hitters from our community and a dedicated triage team who came prepared to ice some bugs.

Hackers ran through a black box engagement discovering a gallery of potential vulnerabilities. This included bugs in the realms of account takeover, authentication, transactions, and live security controls.

With proxies on and scripts ready, a group of 52 hackers from 17 different countries joined us to test their mettle. We are also happy to give a shoutout to seven hackers new to our LHE!

Let’s turn to the scoreboard and give some props to our victors:
