SANS ISC diary RSS entries (Apr 16–22, 2026) summarizing multiple investigations and posts: a guest diary on Telegram 'tdata' files being abused as a credential-harvesting vector (honeypot lessons), reports of threat actors delivering malware via .wav audio files, analysis of Lumma Stealer infections paired with Sectop RAT (ArechClient2), research on compromised DVRs and discovery methods, and guidance on handling the daily CVE flood using EPSS. Several ISC Stormcast podcast items are also listed.
