What happened
SANS ISC diaries (early June 2026) report multiple active abuse techniques: a resurgence of a payload delivered via a MSI-branded background embedded in a JPEG (image-based payload delivery, initially via a WeTransfer link); a spike in phishing emails delivering SVG files used to carry malicious content; ongoing scans probing swagger.json endpoints (exposing potential API/management misconfigurations); and an unidentified RAT observed dropping NetSupport RAT. No specific CVEs are referenced in the entries.
