A empresa Cloudflare publicou estat\u00edsticas sobre a natureza do tr\u00e1fego processado pelo sistema de entrega de conte\u00fado de 1\u00ba de abril de 2023 a 31 de mar\u00e7o de 2024. Durante o ano, a propor\u00e7\u00e3o de tr\u00e1fego HTTP considerado duvidoso, malicioso ou lixo, que foi bloqueado ou redirecionado para p\u00e1ginas de verifica\u00e7\u00e3o para filtrar bots (verifica\u00e7\u00e3o JavaScript ou CAPTCHA), aumentou de 6% para 6,8% em m\u00e9dia ao ano. Os picos desse tipo de tr\u00e1fego chegaram a 12% em certos dias. <\/p>\n
53,9% do tr\u00e1fego bloqueado ou redirecionado para verifica\u00e7\u00e3o adicional est\u00e1 relacionado a atividades maliciosas, tentativas de ataque e atividade de bots, 37,1% \u00e9 de tr\u00e1fego de ataques DDoS, e 7,2% \u00e9 de solicita\u00e7\u00f5es de endere\u00e7os IP<\/a>, com m\u00e1 reputa\u00e7\u00e3o e listadas em listas negras. <\/p>\n Embora o tipo mais popular de ataques a aplicativos web continue a ser os ataques DDoS, que causam nega\u00e7\u00e3o de servi\u00e7o, h\u00e1 um aumento nos ataques direcionados \u00e0 explora\u00e7\u00e3o de vulnerabilidades n\u00e3o corrigidas. Administradores s\u00e3o aconselhados a n\u00e3o atrasar a instala\u00e7\u00e3o de atualiza\u00e7\u00f5es que tratam de vulnerabilidades cr\u00edticas, pois esses ataques est\u00e3o se tornando cada vez mais r\u00e1pidos. Por exemplo, o produto JetBrains TeamCity come\u00e7ou a ser atacado apenas 22 minutos ap\u00f3s a divulga\u00e7\u00e3o do prot\u00f3tipo do exploit para a vulnerabilidade n\u00e3o corrigida CVE-2024-27198, que permite acesso sem autentica\u00e7\u00e3o. Entre os ataques mais ativos est\u00e3o as tentativas de explora\u00e7\u00e3o de vulnerabilidades no Apache Struts (CVE-2023-50164), Apache Spark (CVE-2022-33891), Adobe ColdFusion (CVE-2023-29298, CVE-2023-38203, CVE-2023-26360) e MobileIron (CVE-2023-35082). <\/p>\n 31,2% de todo o tr\u00e1fego est\u00e1 relacionado \u00e0 atividade de bots, enquanto apenas 7% das solicita\u00e7\u00f5es de bots s\u00e3o geradas por servi\u00e7os leg\u00edtimos conhecidos, como motores de busca; os restantes 93% s\u00e3o classificados como bots desconhecidos, que potencialmente podem realizar a\u00e7\u00f5es maliciosas. <\/p>\n Entre as tend\u00eancias, tamb\u00e9m se observa um crescimento do tr\u00e1fego associado a chamadas de Web API, que retornam respostas nos formatos JSON ou XML. A parcela dessas solicita\u00e7\u00f5es alcan\u00e7ou 60% de todo o tr\u00e1fego gerado dinamicamente (n\u00e3o cacheado). Segundo a Cloudflare, um ter\u00e7o das solicita\u00e7\u00f5es de API est\u00e1 relacionado a chamadas para 'APIs sombrias' que n\u00e3o s\u00e3o contabilizadas pelas organiza\u00e7\u00f5es (n\u00e3o s\u00e3o apresentadas como APIs Web publicamente acess\u00edveis) e n\u00e3o s\u00e3o devidamente protegidas. <\/p>\n Em m\u00e9dia, os clientes corporativos da Cloudflare utilizam 47 scripts de terceiros em seus servi\u00e7os web. Os provedores de scripts de terceiros mais populares incluem 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 e Hotjar. <\/p>\n Durante o funcionamento de aplicativos web corporativos, em m\u00e9dia, quase 50 servi\u00e7os externos est\u00e3o sendo conectados (geralmente, os scripts de terceiros transferem dados para hosts externos, por exemplo, o Google Analytics envia estat\u00edsticas para servidores<\/a> Google). Entre os servi\u00e7os externos mais populares aos quais se conecta est\u00e3o: Google (Analytics, Ads), Microsoft (Clarity, Bing, LinkedIn), Meta (Facebook Pixel), Hotjar, Kaspersky, Sentry, Criteo, tawk.to, OneTrust, New Relic e PayPal. \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Cloudflare \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043b\u0430
