ThreatsDay Bulletin: Defender 0-Day, SonicWall Brute-Force, 17-Year-Old Excel RCE and 15 More Stories

This week's ThreatsDay Bulletin covers multiple significant security events including a Windows Defender 0-day vulnerability, SonicWall brute-force attacks targeting network devices, and a 17-year-old Excel remote code execution vulnerability still being exploited. The bulletin aggregates 18 distinct threats in total, encompassing supply chain risks, legacy vulnerabilities, and emerging attack vectors. Organizations should prioritize patching known vulnerabilities, implement network segmentation, enforce strong authentication mechanisms, and monitor for unusual authentication attempts against VPN and firewall infrastructure. The diversity of attack methods suggests threat actors are employing multiple vectors simultaneously, requiring defensive-in-depth strategies.

You know that feeling when you open your feed on a Thursday morning and it's just... a lot? Yeah. This week delivered. We've got hackers getting creative in ways that are almost impressive if you ignore the whole "crime" part, ancient vulnerabilities somehow still ruining people's days, and enough supply chain drama to fill a season of television nobody asked for.
