Is this with JBIG2? I remember reading about JBIG2 also used in the FORCEDENTRY zero click exploit that which was (?) used in the Pegasus spyware. Unrelated tidbit, I guess.

I dealt with this where our fax number had a 6 in it and it would sometimes get changed into an 8, which happened to be a valid fax number for another company, ugh. And this was confidential info too…

Always a funny phone call when they insist they sent it to the number on the cover page we sent and then they send us a copy and xerox made it wrong.

Nice! Just because you’re the top comment, I feel it is helpful to quick readers to point out that it has 0 to do with what happened here. :)

And now practically every phone camera "enhances" the image via AI that might invent details. Most famously Samsung adding details to photos of the moon.

I'm scared that the "AI" marketing will make it much harder convincing non-technical coworkers and execs that "garbage in, garbage out" is a real concept, that not all "data" is good, and that our systems need to keep track of which kind is going where.

"All data is useful, the more the better! Just put it all into the AI and it'll sort it out."

Is this really pervasive? E.g. To my knowledge the "AI" enhancement that iPhones do automatically is limited to the usual sorts of post-processing for contrast, color, etc. There is an AI editing mode that leans more into generative fill capability that would be analogous to the Samsung incident but I don't think it's happening automatically to every photo you take.

I still remember Samsung faking images when using digital zoom...
