An unknown number sends you a blurry photo disguised as a greeting, meme, holiday wish, or advertisement. You click the photo to download it, and a dangerous malware or fake app secretly downloads onto your smartphone.
This malware immediately starts sending your private data to the scammers. It hacks into your banking apps, steals your passwords, and transfers your money instantly.
Officials strictly advise the public to never open or click any files, links, or photos from unknown numbers.
