What happened
SANS ISC entries (Apr 16–22, 2026) cover several operational threats and defensive topics: a guest diary describing Telegram "tdata" folders being abused as a credential-harvesting vector (lessons from a honeypot); reports of threat actors using .wav audio files as malware delivery vectors; an observed Lumma Stealer infection paired with Sectop RAT (ArechClient2); guest research on compromised DVRs in the wild; and a piece on handling the daily CVE flood using EPSS. No specific CVE identifiers were referenced in these items.
