La plus cit\u00e9e est l\u2019analyse de Cyberhaven Labs portant sur la t\u00e9l\u00e9m\u00e9trie de 1,6 million de salari\u00e9s, recueillie aupr\u00e8s d\u2019entreprises utilisant le produit de Cyberhaven entre fin 2022 et environ mi-2023, avec des mises \u00e0 jour ult\u00e9rieures. Il vaut la peine de lire les vrais chiffres plut\u00f4t que leur version en gros titre, parce qu\u2019ils sont plus pr\u00e9cis \u2014 et plus int\u00e9ressants \u2014 que \u00ab tout le monde fait fuiter des donn\u00e9es dans ChatGPT \u00bb.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Les chiffres, tels que publi\u00e9s<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>4,7 %<\/strong> des salari\u00e9s ont d\u00e9j\u00e0 coll\u00e9 au moins une fois des donn\u00e9es confidentielles de l\u2019entreprise dans ChatGPT.<\/li>\n<li>De tout ce que les salari\u00e9s collent dans ChatGPT, <strong>11 %<\/strong> est class\u00e9 comme sensible ou confidentiel \u2014 le code source et les donn\u00e9es clients figurent parmi les principales cat\u00e9gories.<\/li>\n<li>Le comportement est concentr\u00e9 : <strong>0,9 %<\/strong> des salari\u00e9s sont \u00e0 l\u2019origine de <strong>80 %<\/strong> de ces collages.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Lus ensemble, ces trois chiffres racontent une histoire plus pr\u00e9cise que \u00ab 4,7 %, c\u2019est effrayant \u00bb ou \u00ab 4,7 %, ce n\u2019est rien \u00bb. Un pourcentage \u00e0 un chiffre de l\u2019ensemble des salari\u00e9s reste un grand nombre en valeur absolue une fois multipli\u00e9 par le nombre de personnes qui utilisent ChatGPT ou Claude au travail chaque semaine \u2014 mais ce n\u2019est pas tout le monde qui le fait r\u00e9guli\u00e8rement. C\u2019est un groupe plus restreint, qui le fait de mani\u00e8re r\u00e9p\u00e9t\u00e9e, et ce groupe est responsable de fa\u00e7on disproportionn\u00e9e du volume de donn\u00e9es sensibles qui transite par ces outils.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Qui sont probablement ces 0,9 %<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Le chiffre de concentration est celui qui m\u00e9rite qu\u2019on s\u2019y arr\u00eate. Il ne d\u00e9signe pas tant une minorit\u00e9 n\u00e9gligente qu\u2019une minorit\u00e9 de gros utilisateurs \u2014 ceux qui ont int\u00e9gr\u00e9 les outils d\u2019IA assez profond\u00e9ment dans leur quotidien pour y coller en permanence : d\u00e9boguer, r\u00e9diger, r\u00e9sumer, demander un deuxi\u00e8me avis sur un fichier de config. Cette description correspond \u00e0 beaucoup de d\u00e9veloppeurs en activit\u00e9, pas \u00e0 quelqu\u2019un qui ferait quelque chose d\u2019inhabituel. Si vous collez dans un outil d\u2019IA plusieurs fois par jour, le taux de base indique que vous avez plus de chances de faire partie de ces 0,9 % que le salari\u00e9 m\u00e9dian \u2014 c\u2019est bon \u00e0 savoir, non comme une accusation, mais comme une fa\u00e7on plus juste de penser \u00e0 qui cela d\u00e9crit vraiment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Un chiffre dont il faut se m\u00e9fier<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Un autre chiffre, plus bruyant, circule \u00e0 c\u00f4t\u00e9 de ceux de Cyberhaven : l\u2019affirmation selon laquelle \u00ab 77 % des salari\u00e9s font fuiter des donn\u00e9es \u00bb dans les outils d\u2019IA, g\u00e9n\u00e9ralement attribu\u00e9e \u00e0 un rapport de LayerX Security via un article d\u2019eSecurity Planet. Ce titre ne correspond pas aux chiffres sous-jacents tels qu\u2019ils ont \u00e9t\u00e9 publi\u00e9s \u2014 environ 18 % des salari\u00e9s en entreprise collent des donn\u00e9es dans des outils d\u2019IA g\u00e9n\u00e9rative, et plus de la moiti\u00e9 de ces collages contiennent des informations d\u2019entreprise. Passer de \u00ab 18 % collent, et plus de la moiti\u00e9 contient des infos d\u2019entreprise \u00bb \u00e0 \u00ab 77 % font fuiter des donn\u00e9es \u00bb est un raccourci que l\u2019article publi\u00e9 n\u2019explique pas clairement, et il ne pr\u00e9cise ni la taille de l\u2019\u00e9chantillon ni la m\u00e9thodologie compl\u00e8te.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nous pr\u00e9f\u00e9rons citer le chiffre que nous pouvons r\u00e9ellement d\u00e9fendre plut\u00f4t que le plus effrayant. Les chiffres de Cyberhaven s\u2019accompagnent d\u2019une m\u00e9thodologie d\u00e9crite et d\u2019une affirmation pr\u00e9cise et v\u00e9rifiable ; le chiffre de 77 %, pour autant que nous puissions le v\u00e9rifier, ne r\u00e9siste pas au m\u00eame examen. Si vous le voyez cit\u00e9 ailleurs, demandez-vous d\u2019o\u00f9 il vient r\u00e9ellement avant de le reprendre.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Ce que cela signifie au quotidien<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">La lecture honn\u00eate de cette \u00e9tude est plus nuanc\u00e9e que \u00ab personne n\u2019a \u00e0 s\u2019en inqui\u00e9ter \u00bb ou \u00ab tout le monde est \u00e0 un collage d\u2019une fuite \u00bb. Elle ressemble plut\u00f4t \u00e0 ceci : c\u2019est un comportement r\u00e9el, mesur\u00e9, faible mais non nul, concentr\u00e9 chez les personnes qui utilisent le plus les outils d\u2019IA \u2014 ce qui, si vous lisez un article comme celui-ci, vous inclut probablement. C\u2019est une raison de prendre une habitude au moment du collage, pas une raison de paniquer \u00e0 propos de chaque conversation avec une IA que vous avez eue.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ce que l\u2019\u00e9tude ne tranche pas, et nous reconnaissons que c\u2019est encore une question ouverte, c\u2019est si les d\u00e9veloppeurs choisiraient un outil personnel et local pour cela plut\u00f4t que ce que leur employeur fournit d\u00e9j\u00e0 via une solution de pr\u00e9vention des pertes de donn\u00e9es d\u2019entreprise \u2014 c\u2019est une vraie hypoth\u00e8se derri\u00e8re la cr\u00e9ation de PasteCloak, et nous la validons plut\u00f4t que de la tenir pour acquise. L\u2019\u00e9tude nous dit que le comportement est r\u00e9el et document\u00e9 \u00e0 plusieurs reprises par plus d\u2019une \u00e9tude ind\u00e9pendante. Elle ne nous dit pas encore comment les gens veulent le r\u00e9soudre.<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>Une lecture attentive de l\u2019\u00e9tude derri\u00e8re le chiffre \u00ab 11 % de ce qui est coll\u00e9 dans ChatGPT est confidentiel \u00bb, et ce qu\u2019il signifie au quotidien.<\/p>\n","protected":false},"author":1,"featured_media":531,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[23],"tags":[],"class_list":["post-459","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-recherche"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
