Hackers, we’re running a beta with payouts directly to BTC and USDC wallets without needing a Coinbase account. No ETA on general availability but this is now live for the first 300 hackers to test it out.

The live hacking in Las Vegas is EPIC! Scoreboard shows $243,950 and we are only getting going.

Collaboration yields more vulnerabilities and typically higher severities! Go hang out with (internet) friends and hack together!
That is a _lot_ of collaborations recently 👀

Hackers, thanks as always for the on-point feedback! The missing tags, e.g. "Managed by HackerOne", are coming back. See screenshot. In the interim, it's still possible to search on them. And the new ones. I'm excited for programs to respect you by committing to "Fast Payment".

Hackers, based on feedback, we're planning to separate out and make BBP reputation the primary measure on profiles and leaderboards. Further iterations likely to follow -- feedback welcome as always.

Hackers, there's now a better UI for programs to give you testimonials on your public profile. As Chief Hacking Officer, it's my expectation that any top-tier or world-class program uses this to celebrate the best reports. Share with your friends who operate programs!

HackerOne Ambassador World Cup in full swing with over $30,000 paid in bounties in these first days alone. How is your country faring? Bookmark the leaderboard so you can follow! leaderboards.hackerone.live/…

The massive Ambassador World Cup is starting again, with 700 hackers competing in 40 teams. Last year, one of our major customers said it was the best thing they ever did.

Thanks @galnagli for the feedback. There is no new policy but there was a documentation error, which is now fixed. Keep the feedback coming!

The new @Hacker0x01 policy around CVE reports is concerning, especially for High & Critical ones, as it potentially keeps hundreds of their customers vulnerable to critical ransomware-leading risks by withholding information as they are automatically being set as "Informative." A report that could have resulted in a $3,000-$15,000 bounty, based on the customer's assessment of its helpfulness, will very likely become a 6-7 digit Incident Response bill. I hope this policy will change soon, let's break down what happens today when you report a critical CVE to a Managed program: Up until a few weeks ago, programs could set in their policy that they do not accept CVE reports with a public advisory up to 30 days from disclosure. This was a reasonable decision for the program to make when it was harder to exploit, detect, and take down systems. As of the latest update, a site-wide ruling was enforced for the triage teams to not forward any incoming CVE to their customers if it is less than 30 days since disclosure, even if it is a critical LFI/RCE with one simple request, completely overriding the customer's policy that welcomes them. (docs.hackerone.com/en/articl…) Some serious questions arise from this policy: Timing: What constitutes a "reasonable period of time"? For example, with the latest Checkpoint LFI, the public exploitation POC came about 5 days after disclosure, make a drop down for customer to decide based on their own threat model? Validity: The policy states, "The following issues will be closed as invalid except in rare circumstances demonstrating clear security impact." Isn't unauth RCE/LFI enough? Rationale: Researchers will still report these issues, customers would appreciate the value from their bug bounty platform, and the platform would benefit from reporting it first to their customers rather than relying on other security tools. Communication: This may push researchers towards off-platform communications, bypassing triage processes. As a researcher and ethical hacker, I want to ensure the programs are aware of serious risks to their infrastructure. Obfuscation: Researchers might obfuscate their findings to bypass the policy, making it harder for clients to implement fixes. Bug Bounty Goals: One main goal of a Bug Bounty program is to report exploitable CVEs. This policy seems to contradict that. Double Policies: Program's own policy is not being taken seriously if site wide restrictions are over-riding them. Yesterday I was fortunate enough to experience three different outcomes when reporting the Checkpoint VPN CVE (a simple LFI that can lead to an easy RCE): 1. HackerOne Managed Program: Report to a program with a >$10B market value on their main VPN was directly closed as informative, not passed to the team, leaving the appliance vulnerable. HackerOne Managed Program: Report to a program with >$10B market value on 10 VPNs was picked up before triage after tagging the program manager, who is evaluating it and will probably pay for it as they take critical risks super serious. BugCrowd Report: Triager passed the issue to the team due to its criticality. The team acknowledged it was out of scope but decided to pay a courtesy award. This is not just a rant. I genuinely think this policy is a mistake and want to improve processes for everyone involved. This situation appears to be a loss for the platform, customers, and hackers. Potential Solutions: Highway Pass for Critical & High CVEs: Forward these reports to programs as "Pending Program Review," allowing the program to decide on the reward. Set a Reasonable Date: Accept reports "5-7 days" after publication. If a customer hasn't addressed a CVE within a week, additional delay is unlikely to help. Opt-in Policies: Allow programs to opt-in to strict rules rather than auto-enforcing them, ensuring critical information isn't hidden from customers. Again, the goal is to improve the experience for everyone involved in the #BugBounty space, we should definitely find those vulnerabilities and notify the customers over their legacy tools, allowing them to double-down and invest more on their programs. 🙏

I'm very excited about Spot Checks. It's a new way for hackers and enterprises to connect, to build relationships, and generate the same spectacular results they always do.
The spot check feature by @Hacker0x01 is really awesome. Submitted spot check report today at 8:25 pm and got rewarded $500 at 8.56 pm

Hackers, thanks for the feedback on bounty table transparency enhancements. Glad it's useful! Why do this? See screenshot of great program. You deserve to know a program honors its bounty table, uses the extent of any ranges, and is generous with High / Critical severities.

Hackers, today we’re announcing Spot Checks for all; a new way to help organizations all over the world by testing specific areas of their systems. Spot Checks vary in size and often pay out quickly (we’ve seen $500 within minutes). Opportunities show up on @Hacker0x01 and in your email inbox. Happy hacking!
Excited to introduce @Hacker0x01 Spot Checks! Now, customers can perform targeted testing on specific assets, and hackers have new ways to earn. Learn more: hackerone.com/vulnerability-…

Hackers, I think this one's important. You deserve transparency as a matter of fairness and platform integrity. It is now mandatory for programs to always show time-to-bounty related statistics. (Example is from a leading program.)

Every Bug Bounty Program has areas for improvement. IMHO, the mark of a Gold Standard BBP is accepting feedback with humility and making updates. In this instance, we had a bounty table inconsistency. I approved $60,000 in retroactive payouts and we straightened out the table.

HackerOne just gave me $5,000 out of the blue on a report I had forgotten Today is a good day

Great hacking MUST be celebrated! Yes, with robust bounties of course. But also with praise when a hacker's creativity finds something unusual, or deeply hidden, or clever, or unexpected, or just downright impactful, or difficult, or ... ! I commit to giving more Testimonials.

Just received a feedback with nice words from @scarybeasts @Hacker0x01 🤓 this is a big motivation for me and @flysec_corp to keep finding impactful bugs to make the Internet safer 🔥🔥

Hackers, good news: we’ve launched the ability to pause your payments and setting a minimum amount for a small group of hackers — and it’s looking good! We expect to make this available for the entire community in the second half of May.
