Android PDF-advertentiescam: Nep-pop-ups ‘PDF-app bijwerken’ overspoelen telefoons met rommelapps (28 nov 2025)

The ad, disguised as a system message, appeared each time the user tried to open a PDF. Removing WPS Office resolved the problem. Security experts warn similar tactics are used in malware campaigns.
