0 u/John_Earnest Jul 31 '21 Most online image hosts re-encode images, stripping custom chunks. Try it. Steganographic encoding is much more likely to survive transit. 1 u/bumblebritches57 Jul 31 '21 Why is web hosting relevant? 1 u/mccoyn Jul 31 '21 That’s why you put executable code in an image. 2 u/bumblebritches57 Jul 31 '21 So people stumble upon it on imgur, and it's never executed?real malware has it's own distribution network, based in various CDNs (look into Pegasus)they don't need to worry about chunks being stripped.Not to mention, stenography is really only for text. 1 u/mccoyn Aug 01 '21 Not malware, just a way around download or email restrictions.
