Baisse de 75 % des appels pass\u00e9s au nom de pr\u00e9tendues autorit\u00e9s <\/p>\n

Keystone-SDA <\/p>\n

Les appels au nom de pr\u00e9tendues autorit\u00e9s sont de plus en plus contr\u00e9s avec succ\u00e8s en Suisse. Gr\u00e2ce \u00e0 une nouvelle r\u00e9glementation, le nombre de signalements a diminu\u00e9 de plus de 75%. La cybermenace reste toutefois \u00e9lev\u00e9e, surtout \u00e0 l’\u00e8re de l’IA, note la Conf\u00e9d\u00e9ration.\n<\/p>\n

(Keystone-ATS) Les appels frauduleux pass\u00e9s au nom des autorit\u00e9s figurent parmi les incidents les plus signal\u00e9s ces derni\u00e8res ann\u00e9es, rappelle lundi l\u2019Office f\u00e9d\u00e9ral de la cybers\u00e9curit\u00e9 (OFCS). De janvier \u00e0 juin, plus de 400 signalements ont \u00e9t\u00e9 enregistr\u00e9s chaque mois.<\/p>\n

Mais la donne a chang\u00e9 en juillet gr\u00e2ce \u00e0 l\u2019entr\u00e9e en vigueur d\u2019une mesure obligeant \u00e0 identifier les appels provenant de l\u2019\u00e9tranger et usurpant des num\u00e9ros suisses. Le nombre de signalements est pass\u00e9 \u00e0 moins de 100 en juillet (-75%).<\/p>\n

L\u2019OFCS reste cependant vigilant: au premier semestre, il a re\u00e7u 27\u2019128 signalements volontaires et 200 annonces obligatoires quant aux infrastructures critiques. Il avertit contre l\u2019utilisation croissante de l\u2019intelligence artificielle (IA) qui permet de mener des attaques de plus en plus personnalis\u00e9es.<\/p>\n","protected":false},"excerpt":{"rendered":"Baisse de 75 % des appels pass\u00e9s au nom de pr\u00e9tendues autorit\u00e9s Keystone-SDA Les appels au nom de…\n","protected":false},"author":2,"featured_media":274867,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[6],"tags":[45,44,43,23,36],"class_list":["post-274866","post","type-post","status-publish","format-standard","has-post-thumbnail","category-economie","tag-business","tag-economie","tag-economy","tag-suisse","tag-ticker"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ch_fr\/117152274529213206","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/posts\/274866","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/comments?post=274866"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/posts\/274866\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/media\/274867"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/media?parent=274866"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/categories?post=274866"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ch-fr\/wp-json\/wp\/v2\/tags?post=274866"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
