Read article →Watch / listen on YouTube ↗

October 31, 2026. Sales Engineer Briefing. Three customer conversations today. Start with Cursor customers whose developers installed a specific extension version during Thursday’s exposure window; attempted persistence can outlast uninstalling it.

Item one. Cursor extension marketplace: identify the installed build and investigate the host
Item two. Linux kernel networking: distinguish MPTCP listeners from Linux in general
Item three. Help-desk impersonation and AD CS: ask how support access becomes identity access
