The term “Grey Hat” is used within the context of computer security[2] and hacking. First appearing in 1996, the term has been defined and redefined by various hacker groups and communities over the years. A grey hat hacker is known for their ethical yet sometimes legally questionable practices. They often identify and expose security[3] vulnerabilities, prompting improvements in cybersecurity. Grey hat techniques also appear in the world of Optimisation des moteurs de recherche[1] (SEO), where they refer to strategies that, while not outright banned, may still be considered unethical. The grey hat community is a diverse one, sharing knowledge through various platforms and grappling with the ethical implications of their work. It’s important to understand that while grey hat practices can lead to advancements in security, they must be balanced with respect for vie privée[4] rights.

Définitions des termes
1. Optimisation des moteurs de recherche ( Optimisation des moteurs de recherche ) L'optimisation des moteurs de recherche, communément appelée "SEO", est une stratégie de marketing numérique essentielle. Apparue au milieu des années 90, l'optimisation des moteurs de recherche consiste à améliorer les sites web pour qu'ils soient mieux classés dans les pages de résultats des moteurs de recherche. Ce processus est essentiel pour augmenter le trafic web et convertir les visiteurs en clients. Le référencement fait appel à diverses techniques, notamment la conception des pages, l'optimisation des mots clés et la mise à jour du contenu, afin d'améliorer la visibilité d'un site web. Il implique également l'utilisation d'outils permettant de surveiller et de s'adapter aux mises à jour des moteurs de recherche. Les pratiques de référencement vont des méthodes éthiques "chapeau blanc" aux techniques désapprouvées "chapeau noir", le "chapeau gris" se situant à mi-chemin entre les deux. Bien que le référencement ne convienne pas à tous les sites web, son efficacité dans les campagnes de marketing en ligne ne doit pas être sous-estimée. Les tendances récentes du secteur, telles que l'utilisation du web mobile dépassant celle des ordinateurs de bureau, mettent en évidence l'évolution du paysage du référencement.
2. computer security.
1 Computer security, also known as cybersecurity, is a specialized field that involves safeguarding computer systems, networks, and data from digital attacks. These attacks often aim to access, change, or destroy sensitive information, interrupt normal business processes, or exploit system vulnerabilities for malicious purposes. Cybersecurity threats and attacks come in various forms such as malware, phishing, and denial-of-service attacks, among others. To combat these threats, security measures such as access control, firewalls, secure coding, and hardware protection are employed. It's also critical to continuously update these measures, given the evolving nature of cyber threats. The statistics and trends in this field underscore the importance of maintaining robust computer security to prevent potentially costly and damaging breaches.

Chapeau gris (Wikipedia)

A grey hat (greyhat ou gray hat) is a computer hacker ou computer security expert who may sometimes violate laws or typical ethical standards, but usually does not have the malicious intent typical of a black hat hacker.

The term came into use in the late 1990s, and was derived from the concepts of "white hat" and "black hat" hackers. When a white hat hacker discovers a vulnerability, they will exploit it only with permission and not divulge its existence until it has been fixed, whereas the black hat will illegally exploit it and/or tell others how to do so. The grey hat will neither illegally exploit it, nor tell others how to do so.

A further difference among these types of hacker lies in their methods of discovering vulnerabilities. The white hat breaks into systems and networks at the request of their employer or with explicit permission for the purpose of determining how secure it is against hackers, whereas the black hat will break into any system or network in order to uncover sensitive information for personal gain. The grey hat generally has the skills and intent of the white hat but may break into any system or network without permission.

According to one definition of a grey-hat hacker, when they discover a vulnerability, instead of telling the vendor how the exploit works, they may offer to repair it for a small fee. When one gains illegal access to a system or network, they may suggest to the system administrator that one of their friends be hired to fix the problem; however, this practice has been declining due to the increasing willingness of businesses to prosecute. Another definition of grey hat maintains that grey hat hackers only arguably violate the law in an effort to research and improve security: legality being set according to the particular ramifications of any hacks they participate in.

Dans le cadre de la optimisation des moteurs de recherche (SEO) community, grey hat hackers are those who manipulate websites' search engine rankings using improper or unethical means but that are not considered search engine spam.

A recent research study looked into the psychological characteristics of individuals that participate in hacking in the workforce. The findings indicate that grey hat hackers typically go against authority, black hat hackers have a strong tendency toward thrill-seeking, and white hat hackers often exhibit narcissistic traits.
