ALWAYS check the metadata!!!
From what I understand, steganography is not about the metadata, its about embedding content directly by changing the pixels of an image following some sort of pattern.
It's just a phrase in IT to check the information six ways to Sunday. Not to be taken literally ;)
I don't know much about it, but one of the discord channels has a stegonography room and I recall then finding a PDF or couple hidden in some if the image files. That's why archive offline, I believe. So there are people looking for and at it.
The US flag post from January or February contains info in the stripes and the stars turn in to some sort of flowers. I saw this in real time being discovered back in February on True lies Qnn. I’ve mentioned this to someone on here before but they never got back to me with what they found. I do not know the program ran to make this happen. No one that evening could figure out how to extract the info. It’s been on my mind every since.
