Come regola, Monero, a differenza di molte altre criptovalute, non \u00e8 calcolato con speciali Asics, ma con GPU e CPU convenzionali. I server x86 dirottati ottengono quindi un rendimento elevato.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Secondo Intezer, il worm \u00e8 distribuito e controllato centralmente tramite un server di comando e controllo. Regolare <a href=\"https:\/\/webhosting.de\/it\/taegliche-updates-auf-facebook\/\">Aggiornamenti<\/a> sul server suggeriscono che la rete mineraria \u00e8 amministrata da un gruppo di hacker attivo.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-mysql-tomcat-und-jenkins-als-angriffsvektoren\">MySQL, Tomcat e Jenkins come vettori di attacco<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Il worm si diffonde attraverso interfacce pubblicamente visibili di servizi come <a href=\"https:\/\/webhosting.de\/it\/mysql\/\">MySQL<\/a>Tomcat e Jenkins (porte come 8080, 7001 e 3306). Il worm tenta di indovinare le password deboli per questi servizi tramite un attacco di forza bruta. Inizialmente, viene utilizzato un approccio a dizionario, in cui le password usate di frequente sono testate in modo prioritario.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Una volta che il malware ha scoperto una password, distribuisce uno script contagocce via bash o powerhell che installa un minatore MXRig. Inoltre, il verme tenta di <a href=\"https:\/\/webhosting.de\/it\/existenzgruendung-online-chancen-und-stolpersteine\/\">indipendente<\/a> sulla rete del server infetto per poter attingere ad altre risorse per la criptominazione. Attualmente il malware non viene rilevato da un software antivirus ed \u00e8 quindi molto pericoloso, secondo Intezer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pertanto, solo password forti e, se possibile, l'autenticazione a due fattori possono fornire protezione. La societ\u00e0 di sicurezza raccomanda inoltre di disattivare i servizi che non vengono utilizzati e di limitare l'accessibilit\u00e0 dei servizi richiesti dall'esterno. Inoltre, secondo Intezer, un software aggiornato pu\u00f2 spesso prevenire l'infezione da malware.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Un worm scoperto di recente si infiltra nei server Windows e Linux per usare il loro potere per estrarre il Monero. <\/p>","protected":false},"author":2,"featured_media":6502,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_crdt_document":"","inline_featured_image":false,"footnotes":""},"categories":[685],"tags":[951,963,962],"class_list":["post-6501","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-allgemein","tag-hacker","tag-kryptowaehrung","tag-monero"],"acf":[],"_wp_attached_file":null,"_wp_attachment_metadata":null,"litespeed-optimize-size":null,"litespeed-optimize-set":null,"_elementor_source_image_hash":null,"_wp_attachment_image_alt":null,"stockpack_author_name":null,"stockpack_author_url":null,"stockpack_provider":null,"stockpack_image_url":null,"stockpack_license":null,"stockpack_license_url":null,"stockpack_modification":null,"color":null,"original_id":null,"original_url":null,"original_link":null,"unsplash_location":null,"unsplash_sponsor":null,"unsplash_exif":null,"unsplash_attachment_metadata":null,"_elementor_is_screenshot":null,"surfer_file_name":null,"surfer_file_original_url":null,"envato_tk_source_kit":null,"envato_tk_source_index":null,"envato_tk_manifest":null,"envato_tk_folder_name":null,"envato_tk_builder":null,"envato_elements_download_event":null,"_menu_item_type":null,"_menu_item_menu_item_parent":null,"_menu_item_object_id":null,"_menu_item_object":null,"_menu_item_target":null,"_menu_item_classes":null,"_menu_item_xfn":null,"_menu_item_url":null,"_trp_menu_languages":null,"rank_math_primary_category":"685","rank_math_title":null,"inline_featured_image":null,"_yoast_wpseo_primary_category":"692","rank_math_schema_blogposting":null,"rank_math_schema_videoobject":null,"_oembed_049c719bc4a9f89deaead66a7da9fddc":null,"_oembed_time_049c719bc4a9f89deaead66a7da9fddc":null,"_yoast_wpseo_focuskw":null,"_yoast_wpseo_linkdex":null,"_oembed_27e3473bf8bec795fbeb3a9d38489348":null,"_oembed_c3b0f6959478faf92a1f343d8f96b19e":null,"_trp_translated_slug_en_us":null,"_wp_desired_post_slug":null,"_yoast_wpseo_title":null,"tldname":null,"tldpreis":null,"tldrubrik":null,"tldpolicylink":null,"tldsize":null,"tldregistrierungsdauer":null,"tldtransfer":null,"tldwhoisprivacy":null,"tldregistrarchange":null,"tldregistrantchange":null,"tldwhoisupdate":null,"tldnameserverupdate":null,"tlddeletesofort":null,"tlddeleteexpire":null,"tldumlaute":null,"tldrestore":null,"tldsubcategory":null,"tldbildname":null,"tldbildurl":null,"tldclean":null,"tldcategory":null,"tldpolicy":null,"tldbesonderheiten":null,"tld_bedeutung":null,"_oembed_d167040d816d8f94c072940c8009f5f8":null,"_oembed_b0a0fa59ef14f8870da2c63f2027d064":null,"_oembed_4792fa4dfb2a8f09ab950a73b7f313ba":null,"_oembed_33ceb1fe54a8ab775d9410abf699878d":null,"_oembed_fd7014d14d919b45ec004937c0db9335":null,"_oembed_21a029d076783ec3e8042698c351bd7e":null,"_oembed_be5ea8a0c7b18e658f08cc571a909452":null,"_oembed_a9ca7a298b19f9b48ec5914e010294d2":null,"_oembed_f8db6b27d08a2bb1f920e7647808899a":null,"_oembed_168ebde5096e77d8a89326519af9e022":null,"_oembed_cdb76f1b345b42743edfe25481b6f98f":null,"_oembed_87b0613611ae54e86e8864265404b0a1":null,"_oembed_27aa0e5cf3f1bb4bc416a4641a5ac273":null,"_oembed_time_27aa0e5cf3f1bb4bc416a4641a5ac273":null,"_tldname":null,"_tldclean":null,"_tldpreis":null,"_tldcategory":null,"_tldsubcategory":null,"_tldpolicy":null,"_tldpolicylink":null,"_tldsize":null,"_tldregistrierungsdauer":null,"_tldtransfer":null,"_tldwhoisprivacy":null,"_tldregistrarchange":null,"_tldregistrantchange":null,"_tldwhoisupdate":null,"_tldnameserverupdate":null,"_tlddeletesofort":null,"_tlddeleteexpire":null,"_tldumlaute":null,"_tldrestore":null,"_tldbildname":null,"_tldbildurl":null,"_tld_bedeutung":null,"_tldbesonderheiten":null,"_oembed_ad96e4112edb9f8ffa35731d4098bc6b":null,"_oembed_8357e2b8a2575c74ed5978f262a10126":null,"_oembed_3d5fea5103dd0d22ec5d6a33eff7f863":null,"_eael_widget_elements":null,"_oembed_0d8a206f09633e3d62b95a15a4dd0487":null,"_oembed_time_0d8a206f09633e3d62b95a15a4dd0487":null,"_aioseo_description":null,"_eb_attr":null,"_eb_data_table":null,"_oembed_819a879e7da16dd629cfd15a97334c8a":null,"_oembed_time_819a879e7da16dd629cfd15a97334c8a":null,"_acf_changed":null,"_wpcode_auto_insert":null,"_edit_last":"1","_edit_lock":"1609759142:1","_oembed_e7b913c6c84084ed9702cb4feb012ddd":null,"_oembed_bfde9e10f59a17b85fc8917fa7edf782":null,"_oembed_time_bfde9e10f59a17b85fc8917fa7edf782":null,"_oembed_03514b67990db061d7c4672de26dc514":"<iframe title=\"Gaia X\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/NhqLt_NJ6FA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer;
