What happened
SANS ISC diary (late May–early June 2026) highlights multiple active threats and tooling updates: a recent surge of phishing emails delivering SVG attachments (no visible URLs) to bypass detection and deliver malicious content; reports of an unidentified RAT that installs/ pushes NetSupport RAT; a detailed reconstruction of an Akira ransomware kill chain emphasizing the need to correlate perimeter/firewall and Windows event logs to detect pre‑impact activity; a YARA‑X 1.17.0 release (performance improvements + bugfix); and DShield sensor analysis showing a peak in uploaded threats in Dec 2025–
