What happened
This ISC SANS Diary collection highlights multiple security topics: a deep-dive into RCS adoption and DNS NAPTR records (service discovery for SIP-based RCS messaging), noting RCS support for optional end-to-end encryption and digital signatures; a phishing campaign targeting MetaMask browser/mobile wallets; Apple’s June 2026 updates for iOS/iPadOS/macOS/Safari; automation techniques for host reconnaissance using favicon.ico during pentests; and YARA-X 1.18.0/1.19.0 releases. Content is largely informational and defensive, with no specific CVEs called out in the feed items.
