Národní úřad pro kybernetickou a informační bezpečnost (NÚKIB) vydal Zprávu o stavu kybernetické bezpečnosti ČR za rok 2024 (pdf). V loňském roce NÚKIB evidoval dosud nejvíce kybernetických bezpečnostních incidentů s celkovým počtem 268. Oproti roku 2023 se však jedná pouze o drobný nárůst a závažnost dopadů evidovaných incidentů klesá již třetím rokem v řadě. V minulém roce NÚKIB evidoval pouze jeden velmi významný incident a významných incidentů bylo zaznamenáno 18, což oproti roku 2023 představuje pokles o více než polovinu.

Marek Tóth v příspěvku DOM-based Extension Clickjacking: Data ve správcích hesel v ohrožení na svém blogu popsal novou clickjacking techniku s několika variantami útoků a otestoval ji proti 11 správcům hesel. Výsledkem bylo nalezení několika 0-day zranitelností, které mohly ovlivnit uložená data desítek milionů uživatelů. Jedno kliknutí kdekoliv na webové stránce kontrolované útočníkem umožňovalo ukrást uživatelská data ze
