What happened
SANS ISC diary (June 1–5, 2026) reports several active trends: a return of an MSI-branded background payload embedded into an image (observed delivered via WeTransfer), a surge in phishing emails delivering malicious SVG files, ongoing scans looking for swagger.json API definitions, and an unidentified RAT that is distributing NetSupport RAT. These indicate increasing use of image/SVG-based payload delivery and continued reconnaissance/exploitation of exposed API metadata, with commodity RAT propagation observed in the wild.
