Showcasing your vulnerability disclosure policy to the world

Every business needs a vulnerability disclosure policy. Thankfully, a growing number of organisations have one. Yet, those programs are not always a click away. Here’s to a unique plugin for both Chrome and Firefox, because making it easy to report issues need not be much work.

We are all too familiar with the quotidian data breach debacle that organisations go through more often than not. Besides, the initial notice frequently comes from an “anonymous report” or a disgruntled ethical hacker tweeting about your mishandling their repeated vulnerability notifications.

Those are situations we observe, yet many still struggle with preparing for them and the PR mess that inevitably follows. Shooting the messager, coming up with statements that look pretty much like they have been randomly generated , or not responding for months, are all symptoms that you are ill-prepared to handle reports from the broader security community.

The good news: I can haz a VDP

One robust approach to preventing stinky headlines and loss of trust from customers and partners is a vulnerability disclosure policy (VDP). That policy is a commitment that your organisation will receive, evaluate, and if need be, fix vulnerabilities notified by security folks external to the business.
A VDP also clarifies that you will not go after ethical hackers willing to help you improve the security of your service or product.

For a VDP to be efficient, it needs a few essential elements:

  1. Scope: clearly state what is what, identifying assets that your VDP covers.
  2. Safe harbour: specifically directed at ethical hackers, this bit confirms your commitment to not prosecuting well-intentioned researchers who report a vulnerability. That part is particularly important as legal clarity across organisations and countries is extremely challenging to achieve.
  3. How To: the precise mechanism your organisation has set up and, ideally, the details you would want to see added to a vulnerability report. The aim here is to make said report the most useful possible to the organisation’s technical team.
  4. DO’s and DON’Ts: anything you find relevant to smoothen communication.

You get it right: setting up such a policy implies you have thought out roles and responsibilities internally. Rather than a burden, setting a VDP and organising it is a way of developing talent, breaking silos and improving security altogether.

The better news: Showcasing your VDP has never been easier

You have a VDP; you need to feature it prominently on the organisation’s website so it is accessible to anyone who needs it. One way of doing so is creating a dedicated webpage, such as F-Secure.

Another way is thanks to a simple tool that comes in handy, namely security.txt. You fill in the form, download the file and upload it to the business’s website. Your security.txt can contain contact details, or else the link to your ongoing Bug Bounty programme. Indeed, a Bug Bounty programme is a vulnerability disclosure policy with a monetary reward system.

Whichever way you choose, you will want it to be known. Well, now, there is a plugin for that! Enter YesWeHack VDP Finder, the go-to Chrome and Firefox plugin . Whenever you browse the web, the plugin indicates whether a VDP exists. Because making it easy to report issues does not need to be much work!

Download the firefox plugin
Wanna go for a cool – and secure – carpooling service?
We have marked cases where a VDP exists without a security.txt as “room for improvement” to highlight that security.txt is a (draft, for now) standard. As such, it makes locating a VDP policy even easier since one needs no extra browsing to find the contact detail: the security.txt file is always present at www.mywebsite.tld/.well-known/security.txt
Like, really?

YesWeHack EDU, the world’s first Bug Bounty educational platform

YesWeHack, Europe’s leading Bug Bounty company announces the launch of YesWeHack EDU, the world’s first Bug Bounty education platform dedicated to cybersecurity training.

YesWeHack EDU creates a training ecosystem for best practices in cybersecurity, meeting the growing need for talent in this sector.

Taking advantage of recognized expertise in Coordinated Vulnerability Disclosure (CVD), as well as a unique ecosystem of customers and researchers, YesWeHack EDU trains its users to detect security vulnerabilities in realistic scenarios, in identical contexts to what exists today in production within companies and organizations.

Guillaume Vassault-Houlière,
CEO & Co-Founder, YesWeHack

“Cybersecurity is both an economic and societal issue, and this sector suffers from an imbalance between the state of the threat and the market’s defence capabilities,” commented Guillaume Vassault-Houlière, co-founder of YesWeHack. He adds: “To remedy this situation, the capacity of public and private actors to detect and correct shortcomings in a professional and ethical manner must be rapidly strengthened – This requires specialized profiles training and better information sharing. »

YesWeHack EDU is aimed at cybersecurity curriculums in schools and universities and more broadly at all European IT curriculums (e.g. development, big data, etc.) that want to accelerate the sharing of quality datasets.

YesWeHack EDU’s educational approach first encourages emulation through gamification and the involvement of each student in securing their institution. Above all, it opens up prospects for future developers towards promising specializations such as DevSecOps, Data Scientist, Security Analyst, etc. Finally, YesWeHack EDU facilitates the implementation of collaborative projects and cross-functional initiatives between academic institutions and the private sector.

“According to a study published by Gartner, 50% of companies worldwide are expected to use Bug Bounty by 2022, compared to 5% today. We are launching YesWeHack EDU to address the talent shortage faced by the cyber security industry. This program provides the academic community with a sophisticated training platform to professionalize vulnerability management and to train for new cyber jobs, such as DevSecOps, Big Data, SOAR, etc. ” explains Guillaume Vassault-Houlière, CEO & Co-founder of YesWeHack.

YesWeHack will rely on its partner IT-Gnosis, who will provide YesWeHack EDU to schools and universities globally.

Available throughout Europe, the YesWeHack EDU platform is aligned with the SPARTA consortium initiative, of which YesWeHack is a founding member, that aims to strengthen both innovation and research in cybersecurity at the European level.

A quick update on our ranking point system.

We have recently been questioned on how our ranking point system works and how report quality is evaluated.

Our system has evolved quite a lot since inception, and some new report quality rating features have been added.

1- Triaging

The first step of a bug report life cycle is being ( hopefully ) accepted as valid by the program owner, otherwise it is classified as invalid and receives an additional qualification that eventually can lead to a negative rating, as illustrated below:

Note that a valid report can be triaged again as ” Informative ” or ” Won’t Fix ” after validation and before being accepted.

2- Accepted stage

Now that your shiny report has been accepted by the program owner, congratulations, you are now eligible for a reward.
But how are your ranking points calculated exactly?

a – Bounty

Depending on the bounty your report matches, you will be rewarded with ranking points:
– 15 POINTS for every bounty inferior to 500€
– 25 POINTS for every bounty from 500€, to 2000€
– 50 POINTS for every bounty superior to 2000€

b – Quality rating

The program owner can also reward the quality of your report and attribute 1 to 5 additional ranking points.

c – CVSS scoring bonus

Again, the program owner can give you 1 additional point if your report CVSS scoring falls right.

As summed-up in this chart:

You get 7 additional points for a resolved bug, a big thank you.

3- The big picture.

Finally we’ve stitched it all inside a single graph for your convenience.
Is our ranking system clearer?

Lucas aka BitK: high level bug hunter and the brand new YesWeHack Tech Ambassador.

Tell us about yourself, your background ?

I’m Lucas also know as BitK, I am 28 y/o. I’m a French guy who lives in Lyon. If you play CTF we have probably already met during an on site event as I play a lot of them with the French team Hexpresso.

Before joining YesWeHack I was writing / reversing software for power plants.

I’m also a bug hunter, I’ve been in the top 10 hackers on YesWeHack Bug Bounty platform since the launch of the platform.

Why did you join YesWeHack and what is your role ?

It’s a team that I’ve known for quite some time through CTF, Bug hunting and HZVCommunity & Events ( LeHack ).

We share the same principles and I do like the idea of bringing tools to the community.

My role as Tech Ambassador within YesWeHack will be to support the hackers’ community, by providing tools, talks and workshop. I’ll attend the YesWeHack sponsored events, having great time with bug hunters and IT security researchers.

As a bug hunter and CTF player what are you driven by ?

To me, bug hunting is a lot like a puzzle game, I feel like every software, application is vulnerable to some kind of exploitation, you just need to find how.

Writing software is a difficult job, and developers are still human beings, so they make mistakes : our job is to find those mistakes and help developers to fix them before it gets worse.

One thing I love about the hacker community is the willingness to share information, tips or tools. There is always someone better than you in a specific field and most of the time those people will share their knowledge if you ask nicely.

What are the benefits of CTF (Capture The Flag) for those who want to start bug hunting ?

CTF is a bit different from bug bounties, the major difference is that in CTF you know that a vulnerability is there, you goal is “just” to exploit it.

So usually CTF tasks are quite small, you need to exploit a very specific bug. While in bug bounties, you are hacking real enterprise, their website can be huge and sometime you can find yourself lost in the scope. Bug Bounty has a whole reckon phase that CTF don’t have, it’s a new skill to learn.

CTF and Bug Bounties are different, but most of the time I use tricks and tips I’ve learn during CTF to exploit real life application in Bug Bounty.
