Microsoft did another four-digit patch drop today, releasing updates to fix almost 1,100 security vulnerabilities in its Windows operating systems and supported software. This month’s Patch Tuesday addresses 63 critical flaws — including a zero-day in Microsoft Outlook — and comes amid important security updates from other software makers, including Adobe, Apple, Google and Mozilla.
Microsoft today pushed updates to fix at least 56 security flaws in its Windows operating systems and supported software. This final Patch Tuesday of 2025 tackles one zero-day bug that is already being exploited, as well as two publicly disclosed vulnerabilities.
Microsoft warned today that attackers are exploiting a previously unknown security hole in Microsoft Word that can be used to foist malicious code if users open a specially crafted text file, or merely preview the message in Microsoft Outlook.
Last month’s post examining the top email-based malware attacks received so much attention and provocative feedback that I thought it was worth revisiting. I assembled it because victims of cyberheists rarely discover or disclose how they got infected with the Trojan that helped thieves siphon their money, and I wanted to test conventional wisdom about the source of these attacks.
While the data from the past month again shows why that wisdom remains conventional, I believe the subject is worth periodically revisiting because it serves as a reminder that these attacks can be stealthier than they appear at first glance.
