Der Konflikt in der Ukraine hat globale Auswirkungen, und wie jedes globale Ereignis, das mit Konflikten verbunden ist, schafft er die perfekten Umstände, um Cyberangriffe durchzuführen.

Über Nacht wurde eine weitere russische Cyberangriffskampagne gegen Tausende von US-Unternehmen bekannt.
Die Umfrage ergab, dass bei fast allen Unternehmen die Sicherheit der Lieferkette eine höhere Priorität hat als noch vor zwei Jahren. Doch 64 Prozent der Führungskräfte wissen nicht, an wen sie sich im Falle eines Angriffs auf ihre Supply Chain wenden könnten.
Eine Ransomware-Attacke hat die Treibstoffversorgung in weiten Teilen der USA beeinträchtigt, von Texas im Südwesten bis hoch nach New Jersey im Osten. Marcin Kleczynski, CEO von Malwarebytes, hat den Vorfall kommentiert und geht u.a. auf die Spannungen zwischen Russland und den USA ein.
Unternehmen investieren viel Zeit und Geld, um ihre IT-Infrastruktur gegen Angriffe und ungewollte Besucher abzusichern. Meist liegt dabei der Fokus auf der Stärkung der lokalen Infrastruktur, Applikationslandschaft und Cloud-Dienste. Dabei übersehen sie oft eine potenzielle Schwachstelle im System: den Menschen.
Microsoft schloss zum 3. März 2021 mit einem außerplanmäßigen Sicherheitsupdate vier Schwachstellen in den Microsoft Exchange-Server-Versionen 2010 bis 2019. Zunächst stellte Microsoft die Bedrohung als relativ gering dar. Mittlerweile läuft eine beispiellose Angriffswelle auf ungepatchte Exchange-Instanzen.
Die Zahl der von einem Massenhack betroffenen Microsoft Exchange Server steigt stündlich. Bereits zehntausende Systeme sind allein in Deutschland kompromittiert. Das Bundesamt für Sicherheit in der Informationstechnik (BSI) sieht die IT-Bedrohungslage folglich als „extrem kritisch“.
Sophos beschreibt in drei Reports detailliert das Vorgehen einer realen Conti-Ransomware-Attacke und wie sie gestoppt wurde. Mit dabei: Angriffsverhalten, technische Hintergründe und praktische Tipps für IT-Administratoren.
Arcserve, ein Anbieter von Lösungen für Daten- und Ransomware-Schutz, warnt vor der gestiegenen Bedrohung durch Ransomware und stellt einen Strategie-Fahrplan zum Schutz vor Cyber-Attacken vor. Ransomware ist seit der Corona-Krise zu einer noch größeren Bedrohung für die Cybersicherheit von Unternehmen geworden.
Das Link11 Security Operation Center warnt vor erneuten DDoS-Erpressungen im Namen von Fancy Bear, die von großvolumigen DDoS-Attacken begleitet werden. Zu den angegriffenen Unternehmen zählen auch KRITIS-Betreiber.

We firmly believe that the internet should be available and accessible to anyone, and are committed to providing a website that is accessible to the widest possible audience, regardless of circumstance and ability.
To fulfill this, we aim to adhere as strictly as possible to the World Wide Web Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA level. These guidelines explain how to make web content accessible to people with a wide array of disabilities. Complying with those guidelines helps us ensure that the website is accessible to all people: blind people, people with motor impairments, visual impairment, cognitive disabilities, and more.
This website utilizes various technologies that are meant to make it as accessible as possible at all times. We utilize an accessibility interface that allows persons with specific disabilities to adjust the website’s UI (user interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the background and optimizes its accessibility level constantly. This application remediates the website’s HTML, adapts Its functionality and behavior for screen-readers used by the blind users, and for keyboard functions used by individuals with motor impairments.
If you’ve found a malfunction or have ideas for improvement, we’ll be happy to hear from you. You can reach out to the website’s operators by using the following email
Our website implements the ARIA attributes (Accessible Rich Internet Applications) technique, alongside various different behavioral changes, to ensure blind users visiting with screen-readers are able to read, comprehend, and enjoy the website’s functions. As soon as a user with a screen-reader enters your site, they immediately receive a prompt to enter the Screen-Reader Profile so they can browse and operate your site effectively. Here’s how our website covers some of the most important screen-reader requirements, alongside console screenshots of code examples:
Screen-reader optimization: we run a background process that learns the website’s components from top to bottom, to ensure ongoing compliance even when updating the website. In this process, we provide screen-readers with meaningful data using the ARIA set of attributes. For example, we provide accurate form labels; descriptions for actionable icons (social media icons, search icons, cart icons, etc.); validation guidance for form inputs; element roles such as buttons, menus, modal dialogues (popups), and others. Additionally, the background process scans all the website’s images and provides an accurate and meaningful image-object-recognition-based description as an ALT (alternate text) tag for images that are not described. It will also extract texts that are embedded within the image, using an OCR (optical character recognition) technology. To turn on screen-reader adjustments at any time, users need only to press the Alt+1 keyboard combination. Screen-reader users also get automatic announcements to turn the Screen-reader mode on as soon as they enter the website.
These adjustments are compatible with all popular screen readers, including JAWS and NVDA.
Keyboard navigation optimization: The background process also adjusts the website’s HTML, and adds various behaviors using JavaScript code to make the website operable by the keyboard. This includes the ability to navigate the website using the Tab and Shift+Tab keys, operate dropdowns with the arrow keys, close them with Esc, trigger buttons and links using the Enter key, navigate between radio and checkbox elements using the arrow keys, and fill them in with the Spacebar or Enter key.Additionally, keyboard users will find quick-navigation and content-skip menus, available at any time by clicking Alt+1, or as the first elements of the site while navigating with the keyboard. The background process also handles triggered popups by moving the keyboard focus towards them as soon as they appear, and not allow the focus drift outside it.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
We aim to support the widest array of browsers and assistive technologies as possible, so our users can choose the best fitting tools for them, with as few limitations as possible. Therefore, we have worked very hard to be able to support all major systems that comprise over 95% of the user market share including Google Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS and NVDA (screen readers).
Despite our very best efforts to allow anybody to adjust the website to their needs. There may still be pages or sections that are not fully accessible, are in the process of becoming accessible, or are lacking an adequate technological solution to make them accessible. Still, we are continually improving our accessibility, adding, updating and improving its options and features, and developing and adopting new technologies. All this is meant to reach the optimal level of accessibility, following technological advancements. For any assistance, please reach out to
