Cloudflare har offentliggjort statistik om karakteren af trafikken behandlet af indholdsleveringssystemet fra 1. april 2023 til 31. marts 2024. I l\u00f8bet af \u00e5ret er andelen af tvivlsom, skadelig eller skadelig HTTP-trafik, der er blevet blokeret eller omdirigeret til kontrolsider for at afvise bots (JavaScript-kontrol eller captcha), steget fra 6% til 6,8% i gennemsnit. Toppe af s\u00e5dan trafik n\u00e5ede 12% p\u00e5 bestemte dage. <\/p>\n
53,9 % af den blokerede eller dirigerede trafik til yderligere kontrol stammer fra ondsindede aktiviteter, angrebsfors\u00f8g og bot-aktivitet, 37,1 % \u2014 fra DDoS-angretrafik, og 7,2 % \u2014 fra anmodninger fra IP-adresser<\/a>, der har et d\u00e5rligt omd\u00f8mme og er p\u00e5 sorte lister. <\/p>\n Selvom DDoS-angreb stadig er den mest popul\u00e6re type angreb p\u00e5 webapplikationer, der for\u00e5rsager serviceafvisning, er der en stigning i angreb, der sigter mod at udnytte uopdaterede s\u00e5rbarheder. Administratorer anbefales at undg\u00e5 at uds\u00e6tte installationen af opdateringer, der retter kritiske s\u00e5rbarheder, da s\u00e5danne angreb bliver stadig mere rettidige. For eksempel blev JetBrains TeamCity angrebet blot 22 minutter efter offentligg\u00f8relsen af en prototype af exploit til den uoprettede s\u00e5rbarhed CVE-2024-27198, som tillader adgang uden godkendelse. Blandt de mest aktive angreb n\u00e6vnes fors\u00f8g p\u00e5 at udnytte s\u00e5rbarheder i Apache Struts (CVE-2023-50164), Apache Spark (CVE-2022-33891), Adobe Coldfusion (CVE-2023-29298, CVE-2023-38203, CVE-2023-26360) og MobileIron (CVE-2023-35082). <\/p>\n 31,2% af al trafik er relateret til botaktivitet, mens kun 7% af anmodningerne fra bots genereres af kendte legitime tjenester som s\u00f8gemaskiner, mens de resterende 93% henvises til kategorien ukendte bots, der potentielt kan udf\u00f8re skadelige handlinger. <\/p>\n Tendenser viser ogs\u00e5 en stigning i trafik relateret til foresp\u00f8rgsler til Web API'er, der returnerer svar i formaterne JSON eller XML. Andelen af s\u00e5danne foresp\u00f8rgsler har n\u00e5et 60 % af al dynamisk genereret (ikke cachet) trafik. If\u00f8lge estimater fra Cloudflare er en tredjedel af anmodningerne til API'er relateret til s\u00e5kaldte 'skygge'-API-h\u00e5ndterere, som ikke registreres af organisationer (de pr\u00e6senteres ikke eksplicit som offentligt tilg\u00e6ngelige Web API'er) og ikke beskyttes korrekt. <\/p>\n I gennemsnit anvender virksomhedskunder hos Cloudflare 47 tredjeparts scripts i deres webtjenester. De mest popul\u00e6re udbydere af tredjeparts scripts omfatter Google (Tag Manager, Analytics, Ads, Translate, reCAPTCHA, YouTube), Meta (Facebook Pixel, Instagram), Cloudflare (Web Analytics), jsDelivr, New Relic, Appcues, Microsoft (Clarity, Bing, LinkedIn), jQuery, WordPress (Web Analytics, plugins), Pinterest, UNPKG, TikTok og Hotjar. <\/p>\n Under driften af virksomhedswebapplikationer forbindes der i gennemsnit til n\u00e6sten 50 eksterne tjenester (som regel sender de brugte tredjeparts scripts data til eksterne hosts, eksempelvis sender Google Analytics statistik til servere<\/a> Google). Blandt de mest popul\u00e6re eksterne tjenester, der forbindes til, er: Google (Analytics, Ads), Microsoft (Clarity, Bing, LinkedIn), Meta (Facebook Pixel), Hotjar, Kaspersky, Sentry, Criteo, tawk.to, OneTrust, New Relic og PayPal. \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Cloudflare \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043b\u0430
