What happened

SANS ISC diary roundup (Jun 16–23, 2026). Headline: CVE-2024-40766 was patched but systems remained exposed due to an unaddressed configuration issue. Other items: continued prevalence of webshells (new GitHub-launched variant), an e‑banking phishing campaign delivered via IPv4‑mapped IPv6 addresses targeting a major Belgian bank, analysis of coordinated SSH brute‑force behavior over three months, a VHDX‑packed drop that yields a Remcos RAT via embedded JavaScript, discussion of browser visibility gaps that can undermine security controls, and several ISC “Stormcast” podcast entries.
