Zscaler ThreatLabZ observed and blocked over 2,500 targeted Microsoft-themed phishing attempts over three months that used attached HTML/PDF lures to redirect senior executives through fake Google reCAPTCHA pages to fraudulent Microsoft login screens (hosted on .xyz, .club, .online domains) to steal credentials; the report includes IOCs, traffic captures, industry/role targeting breakdowns, and no firm attribution.
