Microsoft Patch Tuesday, February 2018 Edition

Microsoft today released a bevy of security updates to tackle more than 50 serious weaknesses in Windows, Internet Explorer/Edge, Microsoft Office and Adobe Flash Player, among other products.

New(ish) Mirai Spreader Poses New Risks

A cross-platform win32-based Mirai spreader and botnet is in the wild and previously discussed publicly. However, there is much information confused together, as if an entirely new IoT bot is spreading to and from Windows devices. This is not the case.

MS Update 3033929 Causing Reboot Loop

One of the operating system updates Microsoft released on Tuesday of this week — KB3033929 — is causing a reboot loop for a fair number of Windows 7 users, according to postings on multiple help forums. The update in question does not appear to address a pressing security vulnerability, so users who have not yet installed it should probably delay doing so until Microsoft straightens things out.

Microsoft Pushes Patches for Dozens of Flaws

Microsoft today released nine update bundles to plug at least 55 distinct security vulnerabilities in its Windows operating system and other software. Three of the patches fix bugs in Windows that Microsoft considers “critical,” meaning they can be exploited remotely to compromise vulnerable systems with little or no help from users, save for perhaps clicking a link or visiting a hostile Web site.
