ACR Stealer ClickFix campaigns targeting enterprise credentials
- Engineer — Learn: ClickFix-delivered infostealers targeting browser credentials and auth tokens are relevant to understanding how attackers bypass browser security; no patch or config action required, but review whether privileged workstations restrict clipboard-execution lures.
- SOC/IR — Act: Active enterprise campaigns from April–June 2026 using ClickFix lures to harvest credentials and tokens; hunt for ClickFix execution patterns (user-initiated PowerShell/cmd from browser context) and tune EDR/SIEM rules for ACR Stealer IOCs from Microsoft’s published analysis.
- Leader — Learn: Infostealer campaigns targeting enterprise auth tokens are a credential-theft trend worth noting for board-level risk awareness, but this does not require immediate leadership action absent a confirmed incident in your environment.
