## ⚡ Weekly Recap: Proxy Botnets, Browser Ransomware, AI Agent Tricks, Fake PoC Malware and More
A streaming box should not need a threat model. Neither should a username field, a demo repo, a reset flow, or a browser permission prompt. That is the irritating part this week: the risky pieces were ordinary.
Home devices became a routing cover. Clean code pulled dirt from a dependency. Identity shortcuts aged badly. AI systems trusted the wrong instructions. Same soft spot throughout: trust placed one layer too early.
Below is the full recap, since this is apparently what counted as a normal week.

Microsoft today released patches for 204 vulnerabilities. 38 of these vulnerabilities are considered critical, and three have been disclosed before today. Six of the vulnerabilities affect Microsoft cloud solutions and do not require any user action. In addition, Microsoft incorporated 360 different vulnerabilities affecting Chromium into its Edge browser.
This is certainly a busier-than-usual patch Tuesday. In particular, the large number of patched Chromium/Edge vulnerabilities underscores the impact of AI tools on vulnerability discovery.
Some noteworthy vulnerabilities:

CVE-2026-33825 [HIGH] Patch Tuesday - June 2026
Microsoft is publishing 200 vulnerabilities on June 2026 Patch Tuesday . Microsoft is not aware of exploitation in the wild for any of these vulnerabilities, and is aware of public disclosure for three. This is similar to last month’s Patch Tuesday, however several of last month’s vulnerabilities ended up on CISA KEV in the days following their publication. So far this month, Microsoft has provided patches to address 360 browser vulnerabilities, which is an order of magnitude more than has been typical in any given month over the past few years. As usual, browser vulns are not included in the Patch Tuesday count above. Indeed, the vast, and presumably sustained, uptick in the number of browser vulnerabilities has led to Microsoft no longer enumerating Chromium CVEs in the Security Update G
