What's particularly critical: The attack could occur without the user accepting the call.<\/p><\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-uagb-info-box uagb-block-74c7e2d5 uagb-infobox__content-wrap  uagb-infobox-icon-above-title uagb-infobox-image-valign-top\"><div class=\"uagb-ifb-content\"><div class=\"uagb-ifb-title-wrap\"><h3 class=\"uagb-ifb-title\">The consequences<\/h3><\/div><p class=\"uagb-ifb-desc\">Billions of WhatsApp users worldwide were potentially at risk. A single compromised incoming video call was enough to install malware on the device or completely compromise the smartphone. Although WhatsApp quickly released updates (Android version 2.18.302 and later, iOS version 2.18.93 and later), many users remained vulnerable because they didn't update the app regularly.<a href=\"https:\/\/www.heise.de\/news\/Kritische-Sicherheitsluecke-gefaehrdet-Milliarden-WhatsApp-Nutzer-4186365.html?utm_source=chatgpt.com\" target=\"_blank\" rel=\"noreferrer noopener\"><\/a><\/p><\/div><\/div>\n\n\n\n<div class=\"wp-block-uagb-info-box uagb-block-2c2d5058 uagb-infobox__content-wrap  uagb-infobox-icon-above-title uagb-infobox-image-valign-top\"><div class=\"uagb-ifb-content\"><div class=\"uagb-ifb-title-wrap\"><h3 class=\"uagb-ifb-title\">The lesson<\/h3><\/div><p class=\"uagb-ifb-desc\">This incident underscores the importance of regular security audits and updates, as well as proactive security testing. Manufacturers should quickly identify and close vulnerabilities and effectively inform users about necessary updates. At the same time, users should update their apps regularly and be cautious of incoming calls from unknown numbers, especially video calls.<\/p><\/div><\/div>\n\n\n\n<div
