Julien Levrard, Security Operations Manager, OVHcloud:

 DNA. It’s inherent in our business as an infrastructure provider and all of the services that we offer. Our infrastructure security is a permanent focus, as well as a driver of our customers’ trust. That security relies on physical and logical safeguards and oversight activities, scans, internal and external penetration tests, code and configuration reviews, and other security measures. Some of these safeguards are managed non-stop by our teams, while others rely on a partnership with trusted third parties.

 several years ago in order to add a layer of security to our existing systems. Our companies share the same core values and evolve in the same ecosystem; we share the same passion and the same European roots. It’s partly for these reasons that we started with this platform: we were one of 

 clients, and launched our program during a live bug bounty at the Nuit du Hack (Hack Night) event.

Is bug bounty strengthening the trust you have with your customers?

Yes, definitely. OVHcloud works with different types of clients. Some of them manage their infrastructure themselves and are highly sensitive to technical communications. Our communication is therefore based on transparency and reliability. Other customers are more mindful as to our ability to bring in trusted third parties, such as certification auditors or external service providers. 

Bug bounty offers an added degree of trust for some of our customers who demand more than traditional security measures.

 works with large strategic organisations such as OVIs (Operators of Vital Importance) and we also play in that market. 

bug bounty is part of this ecosystem of trust and is becoming a ‘must have’ for organisations like ours

. It’s also a question of reputation vis-à-vis the community of hunters, who are stakeholders in this ecosystem: through YesWeHack, we can interact with people who aren’t always available via other channels.

What does bug bounty offer you in terms of the aforementioned services (audits, scans, penetration tests, etc.)?

Bug bounty puts us in touch with experts with knowledge that complements our teams across the entire spectrum of technologies that we use. This includes OpenStack, Kubernetes, Machine Learning tools, and AI. It’s impossible to find a team of penetration testers with advanced skills in all of these technologies.

YesWeHack gives us easy access to experts in these various technologies who say: 

“I’m a Kubernetes expert, so I’m going to take a look at all of these bug bounty programs with Kubernetes offers and dig deeper

.” This effectively completes our security approach by providing a perspective that complements that of our teams.

Bug bounty also offers a formal framework for vulnerability reporting. It allows us to provide a legally secure point of entry for the hunters. Even if it isn’t the only OVHcloud channel for vulnerability reporting, we recommend to anyone that ‘finds’ vulnerabilities to use our program. This allows us to have one single inflow and a linked process for managing vulnerability reports. It’s therefore a defining part of our 

CVD (Coordinated Vulnerability Disclosure).

Beyond the advantages of bug bounty as a model, I would highlight the YesWeHack platform, which has a very intuitive user interface. The OVHcloud team managing the bug bounty program gives us excellent feedback on the workflow management, report processing, and interactions with the hunters.

The APIs enable us to integrate useful information into our own tools and dashboards automatically. We can also track our bonus budget and the activity of each program. 

At a glance, we understand the status of our programs and can quickly report indicators to our management. Bug bounty is fully integrated into our global security strategy.

What role does bug bounty play in your agile development methodology?

Our team of penetration testers oversees our bug bounty program: two managers are in charge of the program as well as leading the community of hunters. They then work with the various teams affected by the vulnerabilities so that we can integrate them into our management systems and ensure remediation.

Once the vulnerabilities are reported via the platform, we integrate them into our processes: we have an entire organisational structure that we call security management systems, as part of the ISO 27001 certification framework. Documented processes, roles, and responsibilities ensure that each vulnerability, incident, or potential threat is processed and monitored over time by our teams. It is also part of a detailed action plan whose application is verified according to the sensitivity of the product in question, and the associated level of requirement. 

Thanks to the YesWeHack API, we can easily integrate the bug bounty reports into this process. Everything is managed by tickets that are viewable on our dashboards and accessible to our external auditors.

You’re in a public program – how are your exchanges with the community going?

Managing a bug bounty program is a real commitment to all stakeholders involved in making the internet safer. We have a responsibility to be rigorous and transparent in the management and resolution of reported vulnerabilities. This is made easier by the fact the platform provides a framework that facilitates relationships between customers and hunters, with very rich and very direct communication. 

We’re in a relationship where we openly discuss findings on how to analyse a vulnerability. There is no other way to have such productive communication.

We’re working on standardizing the integration of tickets generated by vulnerability reports into our global risk management model. The goal is to unify our risk management regardless of the information source – whether it’s a proven incident or a vulnerability report. It’s about taking advantage of the full potential of APIs to further automate reporting.

We’ve also identified certain hunters who are particularly strong on our public program, with whom we have excellent relationships, or who have very specific skills. We plan to invite these experts onto programs dedicated to specific products. That will probably happen this year.

The ‘first contact’ is the establishment of a conversation between the security researcher having discovered a vulnerability and the manager of the information system affected; it is the nerve centre of efficient coordinated vulnerability disclosure. How do we enable ‘first contact’ then? We have listed the tools that make it possible in a nifty infographic (in English and

Security researchers can make significant contributions to increasing products’ digital security. Yet, ‘first contact’ is hard to establish. More broadly, even when a vulnerability is reported, editors may prefer not to acknowledge it. This silence often drives security researchers to resort to public disclosure as a means of pressuring the publishers to correct the vulnerability.

So, how should one address the discovery and interaction intended to correct a vulnerability when this identification is by an individual outside the organisation? Different means exist to promote 

The ‘first contact’ is the establishment of a conversation between the security researcher having discovered a vulnerability and the manager of the information system affected; it is the nerve centre of a CVD. How do we enable ‘first contact’ then?

An organisation hosts a CERT or uses such a service via a managed services company. It is thus possible to direct all vulnerability disclosure reports to the CERT, which will then ensure coordination of the stakeholders, acting as counsel, intermediary and communicator. Likewise, CERTs are in the best position to preserve necessary pre-disclosure discretion. CERTs ensure there is time to fix. They also monitor the assets in question guaranteeing the vulnerability has not been rediscovered or exploited meanwhile.

It is easy to appreciate the need to inform the essential operators, who would be concerned by a given risk, as well as State services crucial to the Nation’s survival. Hence, the management by a CERT ensures such information reaches the third parties concerned in a privileged and fast manner. The communication circle can evolve before the patch reaches all users, thereby avoiding all malicious use. For example, the CERT-EU facilitates such interactions between the various national CERTs.

Given the difficulty in identifying an entry point allowing for the escalation of vulnerabilities, experts from the cybersecurity community have proposed 

: a file named security.txt, located at a known place in the tree structure of each website. That location needs to remain the same across websites; it is the following: www.mywebsite.tld/.well-known/security.txt.

Various organisations, including BlaBlaCar, Facebook and Google have already adopted this communication channel. For now, security.txt is still a draft standard. Indeed, the project has been submitted to the IETF (Internet Engineering Task Force, an international workgroup that participates in the development of Internet standards) for review and eventual adoption as a standard.

 is a non-partisan non-profit platform which enables vulnerability reporting while maintaining anonymity for the discoverer. Thanks to ZeroDisclo, disclosure can also occur 

 the Tor Browser. Regardless of the web browser the report submitter uses, the report is encrypted with the receiving organisation’s public key, then signed and timestamped by a blockchain. The site sends the report (to a private or national CERT), and the researcher receives a certificate as proof of deposit.

. Indeed, it formalises the report through various criteria enabling the calculation of a CVSS severity score. Even more important, thanks to the report’s encryption, ZeroDisclo acts as a secure ‘transmission belt’. At no time does the platform or the individuals administering it access the details of the vulnerability described.

Thus, coordinated vulnerability disclosure is effortless. Also, ZeroDisclo does not accumulate a dangerous knowledge of the bugs affecting third-party information systems.

Bug Bounty: the comprehensive approach to coordinated vulnerability disclosure

, also known as crowdsourced security, is a collective means of testing the security of a product or service. Each vulnerability receives a reward by the manager of the system concerned according to its severity and thus the risk that its subsequent remediation reduces. In its current version, a Bug Bounty platform brings together international ethical researchers. These platforms enable coordination between an organisation that wants to test the security of its systems and a community of ethical hackers who receive recognition and compensation for their discoveries.

A Bug Bounty program submits a digital service (a website, an API, a mobile application) or a product (a connected car) to ethical hackers for them to examine for potential vulnerabilities. In the case of public Bug Bounty programs, any ethical hacker subscribed to the platform can participate. If the program is private, only a group of preselected hackers takes part.

Bug Bounty is a future standard for cybersecurity in that it materialises collective responsibility for the reduction of digital risk. It embodies the transition (somewhat contrary to popular wisdom) from centralised control of information security towards a ‘decentralised’ approach. The latter is possible through the involvement of a community of ethical hackers. Besides, this securing by the community reduces the number of vulnerabilities likely to be sold to intermediaries with unclear, if not dishonest, motives. Indeed, through Bug Bounty, the researcher who reports a vulnerability receives a financial reward and bolsters their social capital.

Summing up: ways to mobilise collective intelligence

The global and lasting reduction of risk will come from the cooperation of both public and private actors. An international model in this field is essential to avoid all uncoordinated public disclosure. As such, guaranteeing protection for ethical security researchers is paramount. The issue of information sharing is thus crucial, and private actors play an essential role at this stage. Thus, 

the VDPFinder plug-in for Chrome and Firefox

 showcases whether a website one browses has an existing CVD policy. The latter can be an email to a CERT, a security.txt or an ongoing Bug Bounty program.

Mobilising collective intelligence for better security

Since 2015, Firebounty has been helping users discover

disclosure policies (VDPs). For policy discovery on steroids, we have partnered with

, the ‘Internet SIEM’. Read on to find what this boost means for coordinated disclosure.

 exists since 2015 with the primary purpose of allowing security researchers to find disclosure policies of any kind, be it ‘Hall of Fame’ or Bug bounty programs paying rewards. So far, FireBounty harbours thousands of Vulnerability Disclosure Policies (VDPs). Thus, Firebounty is already the world’s most complete VDP directory.

—a one-of-a-kind tool making VDP discovery as effortless as web browsing itself. Thanks to the witty combination of FireBounty’s up-to-date and exhaustive database and VDPFinder’s ease of use, everyone knows in a glimpse how to report a vulnerability and where doing so is rewarded through a Bug Bounty program.

We have been ramping up FireBounty’s capabilities. In our quest to identify and index all VDPs out there, we have been testing a range of solutions. That is how we got to play with ONYPHE. A young, like-minded security-oriented endeavour, ONYPHE goes with the leitmotif ‘Your Internet SIEM’.

Sounds cool, eh? Read on–it gets better.

Security.txt <3 FireBounty: VDPs for anyone to use

, security.txt allows each organisation to create its VDP in a breeze. Doing so happens through a text file located in a defined, well-known path of its website. Imagined by 

, security.txt is becoming a de facto standard, adopted by large corporate websites and personal webpages alike.

Since FireBounty harbours VDPs web over, it is natural to add security.txt to it. Sure thing—but do we need to crawl, like, the 

 web to achieve this? Besides, bot-spidering websites regularly can lead to a variety of misinterpretations and side effects we ought to avoid.

We first tried to discover criteria to guess whether a website is likely to expose security.txt. By using certificate transparency to discover and check websites, we tested different criteria (

 country, certificate authority). But the approach was quick yielding no meaningful correlation with any criterium, and a meagre bunch of security.txt scattered therein.

So there we were, facing the whole internet alone with our powerful yet insufficient crawlers. We logically turned to Shodan, and it worked in a specific manner, providing us with more than 1,500 security.txt. We can do better, however.

ONYPHE is a young French company defining itself as 

. Its active scan of the whole internet—and not only the web–is coupled with other useful sources such as threat list, geolocation data, passive DNS, paste sites and even the darkweb. Thus, ONYPHE collects and indexes a tremendous amount of data.

Naturally, harbouring data is only part of the story. ONYPHE then offers the capacity to easily query these troves of information in a single search form or API. Doing so is how one effortlessly identifies the proverbial needle in the different information categories haystack (

 datascan, synscan, pastries, resolver, ctl, onionscan and many others).

And, last but not least, ONYPHE—just like 

—is founded by security enthusiasts with a deep understanding of the technical challenges practitioners face in their everyday work. Through its innovative approach, it aims to improve tools, so contributing to better cybersecurity for all.

Amongst the cool things Onyphe can do is directing its sensors and tailoring its search to find data, located deep down in a protocol structure—or, like security.txt, in a specific, well-defined path. (Shhhhh, it’s thanks to that feature that 

 actual exposures to the latest top 0-days or internet spread of famous botnets.)

ONYPHE adapted its crawlers to extract security.txt and exposed it 

 its comprehensive API. We now have everything we need to continue identifying security.txt. Since 27 April, a new logo features on many policies listed at FireBounty. Indeed Firebounty daily indexes new security.txt retrieved by ONYPHE. And it now exceeds 3,200 policies ?

We are delighted to see that many VDPs are surfacing. The increasing number of organisations devising a clear path to coordinated vulnerability disclosure indicates that a growing number of people works towards better cybersecurity. Similarly, an ever-growing number of ethical hackers makes use of existing VDPs.

While that effort is commendable, it is vital to remind everyone that a VDP is quite often a passive listening mechanism. FireBounty and VDPFinder aim at showcasing the efforts to quell wild vulnerability disclosure. They are in no way an incentive to aggressively hunt or, worse, ask for a financial reward upfront promising to “disclose if you pay me” where no monetary reward is envisioned. We are

of ours is somewhat special: it tells tales

about the journey from a private bug bounty to a public one.

Olvid, a thriving start-up, made the leap in only four months. Here’s how they did it.

 is an instant messaging (IM) application whose security does not rely on any trusted third party. Unlike other IM applications – such as Signal, WhatsApp, and Telegram which use a central directory to establish secure channels – Olvid does not need a directory. This eliminates:

The risk of a significant hack/leak if an attacker takes control of that directory.

The need for Olvid to collect any personal data, for example, no phone number, name, or email.

Owing to this new security model and the innovative cryptographic protocols implemented, Olvid offers users:

A strong guarantee on the identity of its contacts, without any risk of identity usurpation, fraud, spam, etc.

Total anonymity towards third parties, including our own servers.

At Olvid, we re-implemented everything from scratch. We rely on a minimum of third-party libraries and we have designed the entire application in house.

Having new cryptographic protocols, we needed our implementation to be validated as widely as possible. To achieve that, we worked on three axes:

A ‘theoretical’ ve­­rification of the cryptography, by 

French National Centre for Scientific Research

. This mathematically proves that our protocols delivers the security guarantees that we claim;

 (National Cybersecurity Agency of France requirements);

A bug bounty program mobilising thousands of cybersecurity researchers looking for exploitable vulnerabilities in every corner of our application.

For us, this last verification stage is essential. When you sell a security application, you certainly do not want a hacker to brag about having found a vulnerability in it!

If we want to protect our application from hackers, it must be evaluated by people who use their exact methods and thought process.

We had the opportunity to participate in 

’s Live bug bounty at the International Cybersecurity Forum (FIC). We began our bug bounty experience here being hacked live for two days! We don’t regret it – it was an incredible experience. The event gave us the opportunity to discuss our application with cybersecurity researchers; and it was a very instructive experience, from both technical and business aspects.

You’re now expanding your private program into a public one. What prompted this choice?

, only a few vulnerabilities were reported by the 20 or so participating researchers. None of these were severe.

We deduced from this that our system is robust enough to welcome 

’s entire community. We now want to take advantage of one of bug bounty’s major strengths, crowdsourcing: tens of thousands of researchers bringing different skill sets and methodologies to test the security of our application.

The reason for our move to a public program is simple: we want to offer our users the best possible security guarantee. The more hunters scanning and attacking our app, the better it is for everyone!

Any tip for startups thinking of launching a bug bounty program?

Stop doubting right now! You’ve got to do it! It is indeed a bit scary at first to think that people will actually try to attack your product; but that’s fine, as long as you have the right people doing it.

I guess it’s comfortable to live in denial, thinking that if no-one has succeeded to attack us yet, we’re safe. However, one day, an attack will happen. And the only way to be better prepared for this is to test your application. Penetration testing and certifications are very important as they provide ‘stamps’ that we can show to our clients.

Continuous monitoring by expert hunters validating every new update is critical for every business in today’s world.

Hunters, go ahead. Attack us. We’re waiting! There’s still money to be taken from our wallet 🙂

Vulnerability disclosure must be coordinated to be responsible and is an opportunity to empower the various participants. Coordination means that stakeholders understand their roles and responsibilities. Here’s a handy infographic to put confused minds at ease. It is available in English and

The number of connected digital services (Internet, Bluetooth, etc.) grows. And with it, the issue of vulnerability disclosure management is becoming increasingly urgent. Unknown vulnerabilities constitute a risk. System managers, software publishers and their users must be able to identify that risk to fix. Appropriate management and disclosure of all vulnerabilities are essential for reducing digital security risks.

The question of vulnerability disclosure management is gradually becoming more urgent as the number of connected digital services (Internet, Bluetooth, etc.) increases. Yet, this issue is not new: ever since we began creating digital products and services, the subject of vulnerability disclosure has ignited debates within the information security community.

Creating software that meets all security requirements is no small challenge. It is thus crucial to identify and correct vulnerabilities as fast as possible to prevent their mobilisation by malicious individuals. Information systems are better protected when vulnerabilities are discovered and dealt with.

Vulnerability disclosure must be coordinated to be responsible. It is also an opportunity to empower the various stakeholders. All digital service providers, both public and private, are responsible—not only for the development of the best software possible but also for the responsible management of vulnerabilities.

NEW TO COORDINATED VULNERABILITY DISCLOSURE?

WE’VE GOT YOU COVERED: READ OUR WHITE PAPER.

Identifying a bug is within reach of many individuals. There is no need to work inside a company to recognise a malfunction leading to a security risk. Well-intentioned individuals often identify vulnerabilities and then seek to 

Obstacles to coordinated vulnerability disclosure

Besides, it is a far more delicate situation for an individual outside of the organisation to report the vulnerability. It is impossible to address vulnerability disclosure without considering the motivations of the individuals reporting the bugs in an information system. Depending on the answer to this question, legal penalties may apply. Such legal uncertainty is a frequent hurdle to reporting a vulnerability.

Another obstacle to coordinated disclosure is the absence of a clear and secure communication channel enabling the escalation of active vulnerabilities. Indeed, most organisations with an online presence have no means dedicated to receiving reports of information system bugs. This deficiency explains in part why the organisation in question remains silent in response to reports from well-meaning individuals. This silence endangers the users of the vulnerable service.

Last but never the least, disclosure without anticipating the remediation timeline can also lead to negative consequences for the users.

These issues underscore the need for a transparent and smooth decision-making process. It ensures the digital security of individuals as well as public and private stakeholders and protects the rule of law online.

Clear roles and responsibilities are part of the right answer

Hence, the challenge is to get an ethical hacker who had found a vulnerability to report it to a system manager. The latter can then fix it and mitigate the relevant user risks without harming the hacker in the process. It is thus necessary to put in place a vulnerability disclosure system that benefits all stakeholders. You guessed that right: it is coordinated vulnerability disclosure (CVD). The latter is structured cooperation where ethical hackers report vulnerabilities to the manager of the information system in question.

Any company or public organisation can implement CVD and enable a direct report of the vulnerability to the most relevant entity. It can also involve an intermediary. In both cases, the approach is a coordinated vulnerability disclosure. That process allows an organisation to remedy the loophole before any detailed information concerning it goes public, with all of the negative implications that this can cause.

We have created the infographic below to better grasp the roles and responsibilities of the various participants to a CVD.

ZeroDisclo builds the bridge between an ethical hacker and a CERT. The platform formalises the report through various criteria enabling the calculation of a CVSS severity score. Even more important, thanks to the report’s encryption with the keys of the person submitting the report and of the receiving organisation, ZeroDisclo serves as a ‘transmission belt’. At no time does the platform or the individuals administering it access the details of the vulnerability described.

ZeroDisclo is also available as a .onion instance, enabling coordinated vulnerability disclosure 

. Regardless of the web browser the submitter uses, the report is encrypted with the receiving organisation’s public key, then signed and timestamped by a blockchain. The site sends the report to a CERT; the vulnerability discoverer receives a certificate as proof of deposit. Coordinated vulnerability disclosure is thus possible without ZeroDisclo having to accumulate a dangerous knowledge of the bugs affecting third-party information systems.

Enabling coordinated vulnerability disclosure is essential. ZeroDisclo is a uniquely positioned tool that does just that. The technology behind it does disclosure well.

That is why we deem it necessary also to give the website a spring refresh. The redesigned-from-head-to-toe website aims at seamless navigation—vulnerability disclosure is also done right when it is done through an unambiguous interface. Among other things, the submission form now indicates what parts of the vulnerability report are encrypted. Furthermore, the FAQ provides answers to many questions we have received since the platform’s inception in late 2016.

Indicate which report details are concealed

We heavily insist on the importance of bringing sensitive information to the right people without exposing the discoverer to unnecessary legal danger in the process. Alongside, we need not receive a copy of those details: our work aims to contribute to reducing vulnerabilities, not to stockpile them.

The vulnerability submission form is a central tool on ZeroDisclo. As it enables the discoverer to reach out to the receiving CERT, we have paid particular attention to make it as unambiguous as possible. Hence the little icon that indicates which parts we have access to—and which we do not.

A FAQ to better know what you can(not) do with ZeroDisclo

You have questions; we get that. And get these, too ? Hence a FAQ to reflect the various questions we have received in the past nearly-four years. The page is accessible through the top navigation menu. The questions are under broader 

, clarifying aspects for the different roles that partake in the vulnerability disclosure process.

CERT onboarding and further awareness raising

On the other side of ZeroDisclo’s ‘transmission belt’ is a CERT.

A short yet unambiguous Disclosure Policy

The CERT needs time to investigate. Reproducing the vulnerability may take time; cascading details to all concerned parties and organising fixes is also time-consuming. That is the reason we have outlined a concise yet straightforward Disclosure Policy. Acknowledging it is the final and mandatory step before submitting the vulnerability report.

An infographic to grasp ZeroDisclo in the blink of an eye

We aim for ZeroDisclo to be effortless to use. Yet, there will always be newcomers, both in the hacker community and within CERTs. Hence a dedicated ‘How it works’ page—and infographic has the spotlight therein. We have given it

ZeroDisclo.com: Vulnerability disclosure done right

, we sat down with the Information System Security Expert of a major European financial institution. Read on to learn how a heavily regulated industry implemented Bug Bounty.

Why did you decide to launch a Bug Bounty program?

To be honest, I wasn’t convinced at first. I imagined it was a ‘patchwork’ of various missions being carried out by their pentesters and not an established, focused activity.

 team who pre­sented different advantages that met my security expectations. Following this, we launched an initial 

 campaign on a site we knew well and which we had already tested multiple times before. Choosing a mature scope enabled me to control the potential program costs.

I wasn’t expecting to get any feedback as we were already on our eighth penetration test on the site since I’d been on the job. And the last test had been conducted just the week before. 

But the results proved us wrong: we received multiple vulnerability reports, including one that was critical, just an hour after launching the program

. We now know this vulnerability had existed for 18 months. In other words, 

two pentests had taken place without it being noticed. So, Bug Bounty instantly appealed to us! (Laughs)

What value does Bug Bounty offer compared with traditional cybersecurity solutions, such as penetration testing?

First, you’re getting something close to the real thing. By that I mean we’re not trying to get a comprehensive view of the vulnerabilities. We’re trying to hit right where it hurts immediately. That’s very close to what a real attack would do.

Second, Bug Bounty gives us continuity – vital given the current agility trend. We continually update our internet applications (at least once a month); so, it becomes complicated and costly to pentest each deployment. Bug Bounty enables us to monitor continuously.

Third, the efficiency and quality of the work done by the hunters is exceptional. On sites that we’d tested multiple times, we systematically found vulnerabilities, some of which were critical. The hunters are paid based on results, so their goal is to find something concrete for us – and that’s my goal, too. One of the problems with pentesting is that the results rely entirely on the pentester.

With Bug Bounty, we work with specialists. The hunters won’t necessarily look for every type of vulnerability that may exist on a web application. Instead, they go where they perform the best – and where they can be swift and effective. That’s what we’re looking for, too.

Since we launched our Bug Bounty program, we’ve upped our security game: we found new vulnerabilities. We were able to fix them, and the security of these applications is now a cut above. Ultimately, that’s what a CISO should be aiming for: not just compliance, but enhanced security.
