What it is
The campaign sends hospitality-themed messages through legitimate notification and redirect services, then leads recipients to a ZIP archive that installs a persistent Node.js implant. Using trusted services helps the message resemble authenticated business email and can weaken simple reputation checks. Microsoft documented the approach as an evolution of familiar archive-based malware delivery tailored to booking and guest-service workflows.
Why it is rising
Microsoft observed multilingual lures abusing legitimate notification and redirect services, making malicious messages resemble authenticated email.
