Credential-stuffing the named C-suite via Hunter pattern + breach corpora
Recon enumerates Hunter pattern {f}{last}@iqt.org and ten named senior staff (Steve Bowsher CEO, Dan Geer CISO, Peter Bronez CDO, plus seven SVPs / Partners / Directors). Breach corpora hit 9 of 10 sampled mailboxes — sbowsher@iqt.org alone appears in DemandScience, Evite, LinkedIn, Adapt, LinkedInScrape-2021, ATT-Speculated, Twitter-Scraped, Verifications, Disqus. The plaintext linda@iqt.org:2483000q is the single highest-confidence stuffing primitive. An adversary will very likely attempt this against IQT's Duo-fronted SSO; success is unlikely there but very likely against personal-cloud and third-party SaaS where the same passwords were reused.
Enforce Duo SSO MFA + automated breach-aware credential rotation
IQT already runs Cisco Duo SSO across the workforce (ent_034). Add an automated rotation trigger: any @iqt.org mailbox appearing in a HIBP / commercial-breach-feed match forces a password reset within 24h. Push specifically: rotate the nine mailboxes (sbowsher, kbojack, imyauo, mchadwick, bsmith, glewis, jwilder, cfarley, vpetkoski) that surfaced in DemandScience / Adapt / Verifications / Apollo / LinkedInScrape-2021, regardless of perceived staleness. Maintain credential-rotation cadence on a 90-day basis as a baseline.
