Summary
Observed facts: CISA issued an emergency directive on active exploitation of Cisco SD‑WAN, mandating urgent federal patching [1]. SC Media highlights a broader shift toward vulnerability exploitation as primary attack vector [2]. Wynn Resorts confirmed a breach and addressed attacker claims of data deletion [4]. DarkReading coverage (shared via Mastodon) shows litigation intensifying vendor/customer blame in breaches (Marquis v. SonicWall) [3].
