Are you using LibreOffice? You should be extra careful about what document files you open using the LibreOffice software over the next few days. That's because LibreOffice contains a severe unpatched code execution vulnerability that could sneak malware into your system as soon as you open a maliciously-crafted document file. LibreOffice is one of the most popular and open source alternatives to Microsoft Office suite and is available for Windows, Linux and macOS systems. Earlier this month, LibreOffice released the latest version 6.2.5 of its software that addresses two severe vulnerabilities (CVE-2019-9848 and CVE-2019-9849), but the patch for the former has now been bypassed, security researcher Alex Inführ claims . Though Inführ has not yet disclosed details of the technique that allowed him to bypass the patch, the impact of this vulnerability remains the same, as explained below. 1.) CVE-2019-9848 : This vulnerability, which still exists in the latest version,...

It's 2019, and just opening an innocent looking office document file on your system can still allow hackers to compromise your computer. No, I'm not talking about yet another vulnerability in Microsoft Office, but in two other most popular alternatives— LibreOffice and Apache OpenOffice —free, open source office software used by millions of Windows, MacOS and Linux users. Security researcher Alex Inführ has discovered a severe remote code execution (RCE) vulnerability in these two open source office suites that could be triggered just by opening a maliciously-crafted ODT (OpenDocument Text) file. The attack relies on exploiting a directory traversal flaw, identified as CVE-2018-16858, to automatically execute a specific python library bundled within the software using a hidden onmouseover event. To exploit this vulnerability, Inführ created  an ODT file with a white-colored hyperlink (so it can't be seen) that has an "onmouseover" event to trick victim...

Cybersecurity isn't just another checkbox on your business agenda. It's a fundamental pillar of survival. As organizations increasingly migrate their operations to the cloud, understanding how to protect your digital assets becomes crucial. The shared responsibility model , exemplified through Microsoft 365's approach, offers a framework for comprehending and implementing effective cybersecurity measures.  The Essence of Shared Responsibility  Think of cloud security like a well-maintained building: the property manager handles structural integrity and common areas, while tenants secure their individual units. Similarly, the shared responsibility model creates a clear division of security duties between cloud providers and their users. This partnership approach ensures comprehensive protection through clearly defined roles and responsibilities.  What Your Cloud Provider Handles  Microsoft maintains comprehensive responsibility for securing the foundational eleme...
