AI Weekly Malaysia

ANY.RUN researchers traced a phishing campaign dubbed "CSuite" across 351 sandbox analyses, with 51% of submissions from the United States, 18% from India, and further activity in the Philippines, Australia, the UK, and Canada; technology, manufacturing, government, and consulting showed the highest exposure. Lures impersonate Adobe, DocuSign, Zoom, Google Meet, Dropbox, and Microsoft 365, and the chain splits two ways: installers, archives, or BAT/VBS droppers that install legitimate remote-management tools such as ScreenConnect or Action1, or credential-harvesting and device-code phishing flows that capture Microsoft 365 access and active sessions. One analyzed session showed an Adobe-themed lure delivering a BAT file that elevated privileges and installed ScreenConnect.

Why: The device-code phishing path is the one most startup teams have not locked down: if your Microsoft 365 tenant allows the device-code flow, a lure alone can hand over live sessions without a password prompt, and the RMM path means an endpoint ends up with ScreenConnect or Action1 installed under attacker control. Concretely, check whether your Entra ID conditional access blocks device-code flow, and whether anyone would notice a ScreenConnect or Action1 install on a work laptop — small teams without a SOC typically would not. This is a US-concentrated campaign, so treat it as a check-your-config item rather than an imminent local threat; the text gives no Malaysia-specific figures.
