Well, her behavior with friends could be a sign. If she starts to prioritize a new 'friend' over her partner and their relationship. For example, she'll always make time for this new person but is too busy for her boyfriend. Also, she may become more critical of her partner. She used to accept his flaws but now nit - picks at everything he does. And secrecy around her social media activities. If she used to be open about who she was following and chatting with online, but now she locks her accounts or gets angry when asked about it.
One sign is secrecy. If she starts being very secretive about her phone or where she's been, like always taking her phone to the bathroom or not sharing her location. For example, in a story I heard, the cheating girlfriend would never let her partner see who she was texting.

She may start dressing differently or putting on more makeup just for her webcam sessions. This could indicate that she's trying to impress someone specific she's chatting with on there. In some stories, the wife might also start to be less affectionate towards her husband, as her emotional focus is shifting to the person she's interacting with via webcam.

Maybe a scenario where you and your gf plan a surprise party for her 'little sister'. You both decorate the place, cook delicious food, and when the 'sister' arrives, it's a moment full of joy and celebration. It can strengthen the bond between you, your gf and this important person in her life.
In a business setting, an employee could be caught cheating on their expense reports. This kind of 'caught cheating' is about unethical behavior in a professional context. They might inflate their expenses to get more money from the company, and when the accounting department discovers the false information, they are caught cheating.
One story I heard was that a guy noticed his girlfriend was always on her phone late at night. When he finally got a chance to look, he found flirty messages with another guy. She had been making plans to meet up with this other person behind his back.
